P1开场白I am so honored to be with you to communicate academic questions and ideas.The tile of my academic presentation is “The preparation and catalytic performance of porous silica nanotube functioned with heteroatoms”I shall only take ten minutes of your time.I will talk about the topic on the preparation of porous materials.P2First of all, i wanna introduce myself. I come from nanjing university of technology, nanjing city, china.P3The content is listed as follows.P4All our researches are conducted by the academic thoughts. Generally speaking, we are committed to porous materials. In order to explore high-performance functionalized materials for Pilot experiments and scale-up production; we tune the structure, such as composition and morphology step by step and optimize them further. What’s more, the possible synthesis mechanisms are also investigated. Today, the presentation is based on theright-hand branch.P5It is known that mesoporous silica have excellent characters as the catalyst carrier, such as……..But due to lack of active sites, we have to introduce organic or inorganic species as active sites. And the catalytic performance need to be further improved.P6As we know, the three factors including activity, scale and diffusion factor play decisive role in the catalysis, affecting the yield, selectivity, stability strongly. In our presentation, we mainly focus on the influence of scale factor on the catalysis.P7Due to lack of active sites for mesoporous silica, two main methods (surface loading, modified framework) are widely reported, by which various organic or inorganic active sites can be immobilized on the surface or incorporated into the framework of mesopoous silica.P8Though various morphologies of mesoporos silica were widely synthesized, the synthesis of the mesoporos silica, with three simultaneous characteristics including doped metal, mesoporous structure and specific morphology, is always a challenge, which is rarely reported.In other words, for our case exploring a proper condition, at which the silicon and metal sources can simultaneously hydrolyze, can ensure a desired material.P9Next, let’s look at the synthetic steps. Firstly,…. Then, …. After that, …. At last, we obtained theproducts.P10In this work, by changing the synthesis conditions, such as …, and soon, the pure mesoporous silica with different morphologies were synthesized, including nanosphere, nanorod, helix, capsule and nanotube. We will focus on the preparation and catalytic application of mesoporous silica with nanotube morphology.学术会议英文演讲模板P11the SEM images of samples: A1, A2, A3 are shown in the figure. It can be seen that sample a1 is nanowire-like with length of about 2μm and diameter of about 100nm. When the amount of ... is 0.04 g, the morphology of sample A2 became to be short and th ick rods and the size is about 1μm in length and 400nm in diameter, respectively. With further increasing the amount of ..., the sample A3 and A4 turned to be spherical morphology. It also can be seen that the diameters of samples A3 and A4 are substantially the same about 450nm. However, the spherical morphology of A4 is more regular than that of AThe XRD patterns showed four reflection peaks attributed to (100), (110), (200) and (210), respectively, due to the hexagonal sructure.P12Then, we keep the same amount of ..., increasing the amount of ....We found that the length increased gradually. The XRD patterns also showed the hexagonal sructure of samples B1, B2, B3, BP13Moreover, an additional proof of the hexagonal symmetry structure is given by TEM and the FT pattern. The N2 adsorption-desorption isotherms of the samples B1, B2, B3, B4 exhibit a typical type-IV isotherm.According to the table of structural parameters, we can find that the specific surface area and total pore volume increase gradually, the thickness of wall decrease and there is no obvious change in diameter.P14Furthermore, the possible synthesis mechanism of the mesoporous silica nanotube in dual templates system was proposed. We suggest that due to electrostatic repulsion between positively charged ammonium ions from hydrated ammonia molecules and hydrophilic groups of ..., especially in ammonia (NH3, 25wt.%) solution, the high concentrated ammonium ions provide a crowded and repulsive space to prevent the conjunction of ... molecules, leading to the formation of the rod-like micelles as template to form pore structure instead of sphere-like ones.The role of co-template ... is suggested to tune the length of rod-like micelles by arranging itself along the axis of channel with PEO and PPO part immersed in the hydrophilic and the hydrophobic group of CTA+ respectively. As a result, the mesoporous nanotube with different length will be synthesized. However, the non-polar ... micelles are not affected by positively charged ammonium. When the amount of co-template increased further, the non-polar ... micelles tend to control the morphology of micelles which are sequentially from nanotube, short rod to sphere-like ones. It my be the reason that the non-polar ... micelles would provide stronger attractive force than the electrostatic repulsion derived from the PEO block,ammonium ions and head group of ..., respectively.P15In order to investigate the influence of the morphology and structure of mesoporous silica on catalyticperformance, the samples with copper incorporated weresynthesized.P16The figure shows the SEM and TEM images of samples a1, a2, a3, from which we can see they represent incremental length in the range of about 0.5, 0 and 5μm, and insignificant change in diameter around100nm. In XRD patterns, there are also four reflection peaks for the samples with copper incorprated, respectively, which indicates the incorporation of the inorganic copper salt has no obvious effect on the hexagonal sructure and the ordered degree of pore structure. Moreover, the trends in length and the diameter of nanotube are illustrated.学术会议英文演讲模板P17The N2 adsorption-desorption isotherms of the samples a1, a2, a3 exhibit a typical type-IV isotherm according to the IUPAC classification and no hysteresis loop at the relative pressure range of 0.2≤p/p0≤0.4, implying the samples not only have ordered mesoporous structure but also the uniform pore size. Moreover, the pore diameters did not change significantly at different weight ratio of . The most probable pore sizes ofsamples a1, a2, a3 are determined to be 71, 50, 44 nm, respectively. The structural parameters are listed in following table.P18This table summarized the catalytic activity of copper-modified porous silica nanotube in the direct hydroxylation of benzene with H2O2 as oxidant. The catalysts showed high catalytic activity, and direct proportional relationship between the benzene conversion and the length of the silica nanotube. Considering the similar copper content determined by ICP, the variations of catalytic activities were probably caused by different retention time of reagent in the nanotube with different lengths. P19It is Summary and Future ResearchThis part of research can be summed up from the following three aspects.Mophology control,Catalytic activity and Future research看this slide.P20thanks第二篇、英文国际学术会议开幕词演讲稿学术会议英文演讲模板International Conference on Space T echnologyDistinguished guests, distinguished delegates, ladies and gentlemen, and all the friends:At this special time of wonderful September, in this grand hall of the beautiful city, our respectable guests are here getting together.

Ino rderto selecta optimalmining method, some main factors should be considered carefully, and some proper approach should be followed accord in gly. My report briefly in troduced the main factors affecting the selection of an mining method, and a proper approach to select an mining method.Abstract:Ground Con trolWu Weiwei135501008The terms ground control and strata control, which here are usedin tercha ngeably , date back some 60 years to the early 1930s whe n the use of rock bolts was pioneered in the United Stated. The first international conference on rock pressure and ground con trol was held in Liege, Belgium, in 1951. In esse nee, ground con trol means mai ntai ning rock mass stability by con troll ing the moveme nt of excavati ons in the ground, which can be either rock and soil. This is a specialty engineering field that is important because the design of underground excavation is, to large extent, the design of un dergro und support systems such as pillars and rock rein forceme nt.Although today, ground con trol is no Ion ger solely a mining art since much of it can qualify as an engin eeri ng scie nee, the applicati on of rock and soil mecha nics prin ciples and tech niq ues in day-to-day mine pla nning and desig n is still not com mon. It is hoped that the up-to-date kno wledge digest contained in this chapter will con tribute to betterdissemination and application of ground-control concepts and techniques, some of which have been available for many years but which mining engineers have not availed themselves fully.Theoretical study of equal stress load-bearing-arch strength in deepsoft rock roadwayWan gPi ng135501009Abstract : For the difficult support characteristics of deep-soft rock roadway, accord in gtothe stress distribution law and the bolt support properties, deep-soft rock roadway equal stress bearing arch strength theory by bolt was proposed. The theory is based on the roadwaystress en vir onment, through match the len gth of an chor bolts, it could be formed a more uniform stress distribution of bearing structure in the surrounding rock.This bearing structurewith betterbeari ng ability that will main tai n the stability of roadwa y」n additi on ,the formula of beari ng capacity of circle-beari ng arch has obta in ed, it has a certa in refere nee value for the project of soft rock engin eeri ng in deep.Numerical Simulatio n on Mecha nism of Pre-splitt ing crack un derFilli ng-Mi ningKe Bo 135501010Abstract: In underground mining, especially in reconstructed mining environment, thestudy on con trolli ng blast disturba nee effect and pillar extracti on clamp ing acti on is much lacked.

Observation of the damaged vertical backfill drill-holes in Jin chua n Non ferrous Metal Corporati on (JNMC), Gansu Province, China, given by a digital drill-hole video camera, indicated that there usually exist serious wear zones in casing pipe in vertical backfill drill-hole (CVBH). It was suggested that serious wear positi on of CVBH should be located at an in terface betwee n air and solid-liquid mixture within CVBH. Backfill slurry falls freely and impacts the wall of CVBH n ear the in terface with great mome ntum and en ergy coming from high speed free fall of backfill slurry. The depth of serious wear position of CVBH, i.e., free fall height of backfill slurry in CVBH, can be estimated by the height of vertical backfill drill-hole, the length of horizontal pipeline, the density of slurry and the hydraulic gradient of pipeline system. A case study indicated that the estimation equation of serious damage depth of CVBH was of eno ugh accuracy and was helpful for daily maintenance and man ageme nt of vertical backfill drill-hole.Risk Assessme nt on Block ing of Filli ng Pipeli ne Based on Un certai ntyMeasureme nt TheoryWANG Shi135501020Abstract : In order to forecast the difficult degree on filling pipeline blocking of filling system in deep mine, the assessment model of filling pipeline blocking was established on the basis of the un certa inty measureme nt theory. Ten evaluati on in dexes were selected as the discrim inant ones of the un certa inty measureme nt model. The un certa inty measurement function of each index was obtained based on the in-situ data. The in formati on en tropy theory was used to calculate the weight of each discrim inant in dex, and the predictive value of filli ng pipeli ne block ing was fin ally achieved using the rules of credible recog niti on criteria. The results show that the four evaluati on objects are Lon gshou mine of Jinchuan company, Dahongshan copper mine, Hedong gold mine, and Xincheng gold mine, and the risk grades of them are respectively n ,川,IV , and 川.The in flue nee of evaluatio n system versus the evaluati on in dexes can be comprehe nsively con sidered by the un certa inty measureme nt theory, which is qua ntitatively calculated.Stability an alysis and comprehe nsive treatme nt methods ofIan dslides un der complex mining en vir onment —a case study of DahuIan dslide from Lin bao HenanDai Bing 135501021ABSTRACT : A case study of Dahu Iandslide from Linbao Henan in China was discussed inthis paper. Based on various kinds of basic data, the 3D nu merical model of a geological structure which possesses all kinds of in formatio n in cludi ng the mecha ni cal characteristics and the geometrical parameters of geological disc on ti nu ities were known from previous works. Thus, both the whole geological structure and all kinds of geological components involved in a slope can be visualized on computer, the complicated analysis and calculation can be the n carried out easily and effectively. Firstly, the comb in ati on of 3D nu merical model with some classical theories in slope stabilization can easily provide the present stability factor. Then according to monitoring data of the total station, the potential sliding trends are analyzed if Iandslides do not occur. Secondly, there are a number of un certa in ties on the factors of coupled disaster formi ng, such as, rai nfall, earthquake, and mined-out area. The unascertained mathematics theory is applied to the stability comprehensive analysis. It shows four Iandslide bodies get to be at unstable state if there are some inducements. Thirdly, sliding distanee and movement scope were predicted if Ian dslides occur. On the basis of the analysis above, the treatme nts of the Ian dslide body called isolated method of culvert are proposed. It has solved the con tradict ion of Ian dslide and mining radically, and provides importa nt tech ni cal assura nee for safety and susta in able developme nt of mine.Simple discussi on on filli ng theory and tech no logyGuoHongquan135501022Abstract : The development situation of the cutand fillmethod athome and abroad isprese nted an dits adva ntages are also described such ashigh safety, high recovery ratio and smalldestruction to ecologicenvironmenton ground surface.

Campus emerge ncies are in creas ing in freque ncy and ofte n occur in differe nt forms, which have aroused widely public attention. Campus emergency has the features of social sensitivity, subject activeness, loss additive, as well as showing the characteristics of general emergency, thus abruptness, uncertainty, destructiveness, derivative, diffusivity, sociality. Appare ntly, traditi onal safety con trol system is far from meet ing the requireme nts of curre nt campus security situati on, deep reformatio ns for campussecurity are n eeded. China s policy for emergency management is called “ one plan and three systems(representing emergency response plan and organizational system, mechanism system, legal system) had bee n made in to practice in many doma ins and helped improve their security. It is found that emergency management will be effective and efficient only by: firstly, bringing into play the effort of the whole society (including not only school, educati onal system, family, stude nts that have direct correlati on with emerge ncy, but also media, transport agency, hospital, public security and other social organizations that arein directly associatedwith emerge ncy) and sec on dly, con sideri ng the whole life cycle of emerge ncy (in clud ing four time periods, thus no emerge ncy, before the emerge ncy, duri ng the emergency and after the emergency) to minimize the resulted loss.Based on the “ onepla n and three systems policya nd with the inten ti on of con trolli ng emerge ncy from a timespace perspective, the idea of establishing the Comprehensive Emergency Management System (CEMS) for campus emergencies is put forward. It is rational to expect that there will be resista nee to the system ' s implemathi n for econo mical restrictio n or lack of safety awareness, so more detailed consideration is necessary for the system s eventual accomplishme nt.3-D Numerical Analysis On The RightOpportunity Of Support In SoftRock RoadwayGUI Rong 135501025Abstract : An analysis was made on the soft rock of Yunling tunnel by using the finite eleme nt software ABAQUS.The cha nges of the displaceme nt, stress and plastic zone duri ng the process of con structi on was an alyzed.A nd using the wayto get the right opport un ity of support in the soft rock. It is validated that the method is correctusing the monitoring data and the method will be significant for engineering practicability.Features of pipe transportation of paste-likebackfilling in deep mineYang Jia ng 135501027Abstract : Based on the pipe transportation of paste-like backfilling system of a certaindeep coal mine, dyn amics process was simulated and an alyzed. A two-dime nsion dyn amic model of extraordinary deep and lone pipe was built by GAMBIT, on the base of which, simulation was done by implicit solver of FLUENT 2ddp. The results show that hydraulic loss of pipe transportation is less than the pressure produced by gravity which means backfilli ng material can flow by itself; whe n the in let velocity is 3.2m/s, the maximumvelocity of 4.10m/s isat the elbow and the maximum velocity in the horiz on tai pipe is 3.91m/s, which are both sensible to meet the stability requirement. Results of the simulatio n were proved reliable by the residual mon itor plotti ng of related parameter, so it 'con cluded that the system of pipe tran sportatio n is safe and reliable.Research on heavy metals pollution in soil along the ortransportationroadsideLi Xiaoya n 135501028ABSTRACT : This paper introduces the main sources and transmission of heavy metalpolluti on in the ore tran sportati ons roadside soil and the detect ion methods of heavy metals in the soil, and an alysis the in flue nee degree of the soil polluted by heavy metals accord ing to the main evaluatio n sta ndards at this stage.

第二篇：模拟国际会议演讲稿1.Introduction Thank you very much.Mr.Jiao, for your kind dies and gentlemen, Good afternoon!My name is Lijia, came from Harbin Engineering University.I am honored to have been invited to speak at this conference.Before I start my speech, let me ask a question.Do you know what can affect the properties of foam concrete? Do you think how to reinforced the properties of foam concrete？Most of the investigations on foam concrete in the past have been conﬁned（被限于）to neat cement paste, cement paste with partial replacement with admixtures and to cement–sand mixes.Today, my topic is about Inﬂuence of ﬁller type on the properties of foam concrete.I want to share our interesting research result on reinforced concrete frame with you.The content of this presentation is divided into 4 parts: In section 1, I will introduce what is the foam concrete.In section 2, I will talk about Parameters investigated and mix compositions.In section 3, I will give Eﬀect of water–solids ratio on design density.And finally, I will make a conclusion.2.Body Section 1: the foam concrete Now, I will introduce the foam concrete.Pre-formed(成型的)foam concrete is manufactured（加工）by adding foam, prepared by aerating（充气）a foaming agent solution, to cement paste or cement mortar（灰浆）.The composition（合成物）, physical properties（性能）and uses of foam concrete were discussed in detail（详细的）by Valore, Short and Kinniburgh, Rudnai and Taylor.Although several investigations have been conducted on the properties of foam concrete, most of them deal with cement–sand mixes, neat cement paste with or without partial replacement（局部替换）using admixtures（掺合料）.Few studies report on the inﬂuenceof ﬁller type on the properties of foam concrete.By using ﬂy ash （粉煤灰）as ﬁller(ﬁne aggregate细骨料)instead of sand, the high volume（体积）utilization（利用）of ﬂy ash becomes possible可能, thus providing a means of eco-nomic（经济）and safe disposal（处理）of this waste parison（比较）of strength of air-cured foam concrete made with cement-sand and cement–ﬂy ash for masonry（砌体结构）by Durack and Weiqing show that for products of comparable density（比较密度）, mixes with ﬂy ash as ﬁne aggregate in place of sand gave relatively higher strength.Section 2: Parameters(参数)investigated and mix compositions（组成成分）So much for the foam concrete, now I will move on to Parameters(参数)investigated and mix compositions.As the experimental programme(实验程序)was aimed at studying the eﬀect of the ﬁllers on the properties like density（密度）, ﬂow behaviour（流动特性）, water absorption（吸水率）and strength of foam concrete, the following mixeswere investigated by keeping the basic ﬁller–cement ratio constant（恒定不变）at 1:1 by weight.The foam required for three densities（密度）of foam concrete viz.1000, 1250, 1500 kg/m3 were arrived at as per ASTMC 796-97.In the cement–sand–ﬂy ash mixes 50% of the sand is replaced with ﬂy ash and in the cement–ﬂy ash mixes all the sand is replaced with ﬂy ash.Section 3: Eﬀect of water–solids ratio（水砂比率）on design density That bring me to Eﬀect of water–solids ratio（水砂比率）on design density.I think this part is the most important in my presentation, I will explain in detail.As the foam is added to the wet foam concrete mix, the consistency（稠度）of the wet mix is very important to get the design density.Fig.2(a)and(b)show the variation of density ratio（密度变化率）(measured fresh densitydivided（分离）by design density)with water–solids ratio for mixes with diﬀerent ﬁller type for each of the design densities, viz., 1000 and 1500 kg/m3, respectively（分别地）.It is observed that at lower water–solids ratios, i.e., at lower consistency, the density ratio is higher than unity（个体）.The mix is too stiﬀ（严格地）to mix properly thus causing the bubbles（气泡）to break during mixing resulting in increased density.At higher water–solids ratios there is also an increase in density ratio as higher water contents make the slurry（泥浆）too thin to hold the bubbles resulting in segregation（分离）of the foam from the mix along with segregation of the mix itself thus causing an increase in measured density.Therefore, as shown in Fig.2(a)and(b), a density ratio of unity or nearly unity is achieved only at a particular consistency.This consistency requirement for the mix before adding foam to it can be expressed in terms of water–solids ratio.It is also observed that the water–solids ratio required to obtain a density ratio value of one, depends on the ﬁller type.Section 4: Conclusion The conclusions drawn from this study and summarized below are applicable（合适的）to the characteristics of the materials（材料特性）used and the range of parameters（参数范围）investigated:(i)the consistency of pre-formed foam concrete mixtures(deﬁned as the water–solids ratio for achieving the target（目标）density)mainly depends on the ﬁller type, i.e., relatively higher for mixes with ﬂy ash as ﬁller compared to mixes with sand;(ii)the ﬂow behaviour mainly depends on the foam volume and as the foam volume increases the ﬂow decreases.For a given density, foam concrete with ﬂy ash as ﬁller showed relatively（相当的）higher ﬂow values;(iii)for a given density, an increase in ﬂy ash content of the mix results in increased strength.In comparison（比较）to cement–sand mixes,cement–ﬂy ash mixes showed relatively higher water absorption （吸收）.That’s all.Thank you!Are there any questions?The picture on this slide isSo much for......, now I will move on to......This slide shows the calculation resultAs we know, the target user usually has taken a list of courses rather than a course, so we need to extent our probability calculation formulars.For example, suppose T={a,b}, Pr[x﹁T] the probability x occurs without either an a or b preceding it;Pr[x﹁T] the probability x occurs without either an a or b following it.This probability can be calculated exactly.So how to calculate it?That bring me to Recommendation Algorithms.I think this part is the most important in my presentation, I will explain in detail.In conclusion, we proposed a novel precedence mining model, developedTo sum up, first, I introduced the motivation and the outline of work;second, I gave the definition of precedence mining model;third, I described some new recommendation algorithms using precedence information;forth, I showed our experimental results to compare the new algorithms with traditional ones.Finally, I made a conclusion of our work..That’s all.Thank you!Are there any questions?第三篇：模拟国际会议演讲稿Recsplorer:Recommendation Algorithms Based on Precedence Mining1.Introduction Thank you very much, Dr.Li, for your kind dies and gentlemen, Good morning!I am honored to have been invited to speak at this conference.Before I start my speech, let me ask a question.Do you think recomemdations from others are useful for your internet shopping? Thank you.Itis obvious that recommendations play an important role in our daily consumption decisions.T oday, my topic is about Recommendation Algorithms Based on Precedence Mining.I want to share our interesting research result on recommendation algorithms with you.The content of this presentation is divided into 5 parts: in session 1, I will intruduce the tradictional recommendation and our new strategy;in session 2, I will give the formal definition of Precedence Mining;in session 3, I will talk about the novel recommendation algorithms;experimental result will be showed in session 4;and finally, I will make a conclusion.2.Body Session 1: Introduction The picture on this slide is an instance of recommemdation application on amazon.Recommender systems provide advice on products, movies,web pages, and many other topics, and have become popular in many sites, such as Amazon.Many systems use collaborative filtering methods.The main process of CF is organized as follow: first, identify users similar to target user;second, recommend items based on the similar users.Unfortunately, the order of consumed items is neglect.In our paper, we consider a new recommendation strategy based on precedence patterns.These patterns may encompass user preferences, encode some logical order of options and capture how interests evolve.Precedence mining model estimate the probability of user future consumption based on past behavior.And these probabilities are used to make recommendations.Through our experiment, precedence mining can significantly improve recommendation performance.Futhermore, it does not suffer from the sparsity of ratings problem and exploit patterns across all users, not just similar users.This slide demonstrates the differences betweencollaborative filtering and precedence mining.Suppose that the scenario is about course selection.Each quarter/semester a student chooses a course, and rates it from 1 to 5.Figure a)shows five transcripts, a transcript means a list of course.U is our target student who need recommendations.Figure b)illustrates how CF work.Assume similar users share at least two common courses and have similar rating, then u3 and u4 are similar to u, and their common course h will be a recommendation to u.Figure c)presents how precedence mining work.For this example, we consider patterns where one course follows another.Suppose patterns occour at least two transcrips are recognized as significant, then(a,d),(e,f)and(g,h)are found out.And d, h, and f are recommendation to u who has taken a, g and e.Now I will a probabilistic framework to solve the precedence mining problems.Our target user has selected course a , we want to compute the probability course x will follow, i.e., Pr[x|a].﹁howerve, what we really need to calculate is Pr[x|aX] rather than Pr[x|a].Because in our context, we are deciding if x is a good recommendation for the target user that has taken a.Thus we know that our target user’s trans cript does not have x before a.For instance, the transcript no.5 will be omitted.In more common situation, our target user has taken a list of courses, T = {a,b,c,…} not﹁just a.Thus, what really need is Pr[x|TX].The question is how to figure out this probability.I will answer it later.Session 2: Precedence Mining We consider a set D of distinct courses.We use lowercase letters(e.g., a, b, …)to refer to courses in D.A transcript T is a sequence of courses, e.g., a-> b-> c-> d.Then the definition of Top-k Recommendation Problem is as follows.Given a set transcripts over D for n users, the extra transcript T of atarget user, and a desired number of recommendations k, our goal is to: 1.Assign a score score(x)(between 0 and 1)to every course x ∈ D that reflects how likely it is the target student will be interested in taking x.If x ∈ T , then score(x)= ing the score function, select the top k courses to recommend to the target user.To compute scores, we propose to use the following statistics, where x, y ∈D: f(x): the number of transcripts that contain x.g(x;y): the number of transcripts in which x precedes course y.This slide shows the calculation result of f(x)and g(x,y).For example, from the table, we know that f(a)is 10 and g(a,c)is 3.We propose a precedence mining model to solve the Top-k Recommendation Problem.Here are ﹁some notation: xy, which we have memtioned in session 1, refers to transcript where x occurs without a preceding y;x﹁y refers to transcript where x occurs without y following it.We use quantities f(x)and g(x,y)to compte probabilities that encode the precedence information.For instance, from formular 1 to 7.I would not tell the detail of all formulars.We just pay attention to﹁formular 5, note that this quantity above is the same as: Pr[x﹁y |yx] which will be used to compute score(x).As we know, the target user usually has taken a list of courses rather than a course, so we need to﹁extent our probability calculation formulars.For example, suppose T={a,b}, Pr[xT] the probability x occurs without either an a or b preceding it;Pr[x﹁T] the probability x occurs without either an a or b following it.This probability can be calculated exactly.So how to calculate it?Session 3: Recommendation Algorithms Let’s review session 2.The main goal of the recommendation algorithms is to calculate the score(x), and then select the top k courses based onthese scores.Traditional recommendation algorithms compute a recommendation score for a course x in D only based on its frequency of occurence.It does not take into account the courses taken by the target user.Our recommendation algorithms called SingleMC conquer the shortcoming of the traditional ones.It computes the score(x)using the formular 5.The detail is as follows: a student with a transcrip T of taken courses, for the course y ∈ T, if y and x appear together in transcripts satisfies the ﹁threshold θ, then compute the Pr[x﹁y |yx], reflecting the likelihood the student will take course x﹁and ignoring the effect of the other courses in T;finally the maximum of Pr[x﹁y |yx] is choosen as the score(x).Here is the calculation formular of score(x)of SignleMC.For example, with the higer score, d will be recommended.Another new recommendation algorithm named Joint Probabilities algorithm, JointP for short, is proposed.Unlike SingleMC, JointP takes into account the complete set of courses in a transcript.In formular 12, we cannot compute its quantity exactly, Remember this problem we have mentioned.Our solution is to use approximations.This slide is about the first approximating formular.And this the second approximating formular.The system is courseRand, and data set for experiment contains 7,500 transcripts.This slide shows the new recommendation algoritms with black color and the traditional ones with blue color.The chart on this slide indicates our new recommendation algorithms beat the traditional ones in precision, because the former ones exploit patterns across all users, while the latter ones just use the similar users.The chart on this slide points out our new recommendation algorithms also beat the traditional ones in coverage for the same reason.Session 5: Conclusion and Summary In conclusion,we proposed a novel precedence mining model, developed a probabilistic framework for making recommendations and implemented a suite of recommendation algorithms that use the precedence information.Experimental result shows that our new algorithms perform better than the traditional ones, and our recommendation system can be easily generalized to other scenarios, such as purchases of books, DVDs and electronic equitment.To sum up, first, I introduced the motivation and the outline of work;second, I gave the definition of precedence mining model;third, I described some new recommendation algorithms using precedence information;forth, I showed our experimental results to compare the new algorithms with traditional ones.Finally, I made a conclusion of our work..That’s all.Thank you!Are there any

P1开场白I am so honored to be with you to communicate academic questions and ideas.The tile of my academic presentation is “The preparation and catalytic performance of porous silica nanotube functioned with heteroatoms”I shall only take ten minutes of your time.I will talk about the topic on the preparation of porous materials.P2First of all, i wanna introduce myself. I come from nanjing university of technology, nanjing city, china.P3The content is listed as follows.P4All our researches are conducted by the academic thoughts. Generally speaking, we are committed to porous materials. In order to explore high-performance functionalized materials for Pilot experiments and scale-up production; we tune the structure, such as composition and morphology step by step and optimize them further. What’s more, the possible synthesis mechanisms are also investigated. Today, the presentation is based on the right-hand branch.P5It is known that mesoporous silica have excellent characters as the catalyst carrier, such as……..But due to lack of active sites, we have to introduce organic or inorganic species as active sites. And the catalytic performance need to be further improved.P6As we know, the three factors including activity, scale and diffusion factor play decisive role in the catalysis, affecting the yield, selectivity, stability strongly. In our presentation, we mainly focus on the influence of scale factor on the catalysis.P7Due to lack of active sites for mesoporous silica, two main methods (surface loading, modified framework) are widely reported, by which various organic or inorganic active sites can be immobilized on the surface or incorporated into the framework of mesopoous silica.P8Though various morphologies of mesoporos silica were widely synthesized, the synthesis of the mesoporos silica, with three simultaneous characteristics including doped metal, mesoporous structure and specific morphology, is always a challenge, which is rarely reported.In other words, for our case exploring a proper condition, at which the silicon and metal sources can simultaneously hydrolyze, can ensure a desired material.P9Next, let’s look at the synthetic steps. Firstly,…. Then, …. After that, …. At last, we obtained theproducts.P10In this work, by changing the synthesis conditions, such as …, and soon, the pure mesoporous silica with different morphologies were synthesized, including nanosphere, nanorod, helix, capsule and nanotube. We will focus on the preparation and catalytic application of mesoporous silica with nanotube morphology.学术会议英文演讲模板P11the SEM images of samples: A1, A2, A3 are shown in the figure. It can be seen that sample a1 is nanowire-like with length of about 2μm and diameter of about 100nm. When the amount of ... is 0.04 g, the morphology of sample A2 became to be short and thick rods and the size is about 1μm in length and 400nm in diameter, respectively. With further increasing the amount of ..., the sample A3 and A4 turned to be spherical morphology. It also can be seen that the diameters of samples A3 and A4 are substantially the same about 450nm. However, the spherical morphology of A4 is more regular than that of AThe XRD patterns showed four reflection peaks attributed to (100), (110), (200) and (210), respectively, due to the hexagonal sructure.P12Then, we keep the same amount of ..., increasing the amount of ....We found that the length increased gradually. The XRD patterns also showed the hexagonal sructure of samples B1, B2, B3, BP13Moreover, an additional proof of the hexagonal symmetry structure is given by TEM and the FT pattern. The N2 adsorption-desorption isotherms of the samples B1, B2, B3, B4 exhibit a typical type-IV isotherm.According to the table of structural parameters, we can find that the specific surface area and total pore volume increase gradually, the thickness of wall decrease and there is no obvious change in diameter.P14Furthermore, the possible synthesis mechanism of the mesoporous silica nanotube in dual templates system was proposed. We suggest that due to electrostatic repulsion between positively charged ammonium ions from hydrated ammonia molecules and hydrophilic groups of ..., especially in ammonia (NH3, 25wt.%) solution, the high concentratedammonium ions provide a crowded and repulsive space to prevent the conjunction of ... molecules, leading to the formation of the rod-like micelles as template to form pore structure instead of sphere-like ones.The role of co-template ... is suggested to tune the length of rod-like micelles by arranging itself along the axis of channel with PEO and PPO part immersed in the hydrophilic and the hydrophobic group of CTA+ respectively. As a result, the mesoporous nanotube with different length will be synthesized. However, the non-polar ... micelles are not affected by positively charged ammonium. When the amount of co-template increased further, the non-polar ... micelles tend to control the morphology of micelles which are sequentially from nanotube, short rod to sphere-like ones. It my be the reason that the non-polar ... micelles would provide stronger attractive force than the electrostatic repulsion derived from the PEO block, ammonium ions and head group of ..., respectively.P15In order to investigate the influence of the morphology and structure of mesoporous silica on catalyticperformance, the samples with copper incorporated weresynthesized.P16The figure shows the SEM and TEM images of samples a1, a2, a3, from which we can see they represent incremental length in the range of about 0.5, 0 and 5μm, and insignificant change in diameter around100nm. In XRD patterns, there are also four reflection peaks for the samples with copper incorprated, respectively, which indicates the incorporation of the inorganic copper salt has no obvious effect on the hexagonal sructure and the ordered degree of pore structure. Moreover, the trends in length and the diameter of nanotube are illustrated.学术会议英文演讲模板P17The N2 adsorption-desorption isotherms of the samples a1, a2, a3 exhibit a typical type-IV isotherm according to the IUPAC classification and no hysteresis loop at the relative pressure range of 0.2≤p/p0≤0.4, implying the samples not only have ordered mesoporous structure but also the uniform pore size. Moreover, the pore diameters did not change significantly at different weight ratio of . The most probable pore sizes ofsamples a1, a2, a3 are determined to be 71, 50, 44 nm, respectively. The structural parameters are listed in following table.P18This table summarized the catalytic activity of copper-modified porous silica nanotube in the direct hydroxylation of benzene with H2O2 as oxidant. The catalysts showed high catalytic activity, and direct proportional relationship between the benzene conversion and the length of the silica nanotube. Considering the similar copper content determined by ICP, the variations of catalytic activities were probably caused by different retention time of reagent in the nanotube with different lengths. P19It is Summary and Future ResearchThis part of research can be summed up from the following three aspects.Mophology control,Catalytic activity and Future research看this slide.P20thanks第二篇、英文国际学术会议开幕词演讲稿学术会议英文演讲模板International Conference on Space TechnologyDistinguished guests, distinguished delegates, ladies and gentlemen, and all the friends:At this special time of wonderful September, in this grand hall of the beautiful city, our respectable guests are here getting together.

On the one hand, the running environment of PMSM is becoming more and more complex so that the PMSM is affected by compound action of the electricity, heat and force. On the other hand, motor supply power can change with the fluctuation of the power system load. These above factors are likely to change the PMSM parameters minorly in long-running so that operation parameters will be further worse if the operating environment has not been improved in time, which leads to the PMSM fault at last.

Conclusion
(1) The relationship between output torque and PMSM power voltage sag under the fault state is approximately inversely proportion; the output torque fluctuation is obviously increased along with the fault severity degree; the output torque contains 2 times rated frequency harmonics because of the negative sequence component existed in power voltage, which affects the operation performance of the motor. (2) The results of simulation and experiment show that the three-phase current is no longer symmetric under the fault state, and the waveform basically retains its shape of sine; fault phase current fundamental wave amplitude decline scale is more than fault phase voltage sag scale, and the current wave has obviously distorted, in which the 3rd harmonic component increases obviously.

Compared with other motors, with no armature and slip ring PMSM has the advantages of simple structure and high reliability, and with no current excitation and excitation loss it has high efficiency, and with no rotor fundamental iron loss and copper loss it has high power factor, all which has been widely used in aviation, new energy vehicle, industrial production and so on.
