英语阅读觉知策略
英语阅读觉知策略一、英语阅读觉知策略的中文翻译与英文解释1. 中文翻译“英语阅读觉知策略”:English reading awareness strategies。
2. 英文解释Awareness in English reading strategies refers to the conscious understanding and perception that readers apply during the process of reading English texts. It involves being aware of various elements such as the text structure (e.g., beginning, middle, and end; different paragraphs' functions), the purpose of the reading (whether it is for general understanding, finding specific information, or analyzing the text), the language features (vocabulary usage, grammar patterns, and rhetorical devices), and one's own reading process (such as comprehension difficulties, areas of confusion, and the speed of reading). By being aware of these aspects, readers can better adjust their reading methods, improve reading efficiency, and enhance comprehension.二、运用英语阅读觉知策略的情况及例子1. 情况一:初读文章确定主旨大意时- 例子1:When reading a news article about a scientific discovery. For instance, an article titled “New Breakthrough in Cancer Treatment”. By using awareness strategies, the reader first looks at the headline, which gives a clue about the main topic. Then, quickly scanning the first and lastparagraphs can help identify the overall message, like whether it's about a new treatment method, its potential impact, etc.- 例子2:Reading a short story. In a story called “The Lost Key”, the reader can be aware of the setting and main characters introduced at the very beginning. By skimming through the initial paragraphs, one can get a sense of where the story takes place (e.g., in an old mansion) and who the key characters are (maybe a young detective and the owner of the mansion), which helps in understanding the general plot.2. 情况二:寻找特定信息时- 例子3:When looking for a particular date in a historical document. Say, in a text about World War II, if one needs to find out the date when a certain battle started. Using awareness of the text structure, the reader might know that dates are often mentioned along with events in a chronological order. So, they can quickly scan the relevant parts of the text (such as sections dealing with military operations) to find the specific date.- 例子4:Searching for a product's price in a shopping catalogue. In a catalogue full of various products and descriptions, the reader, being aware of the common layout where price information is usually placed near the product name or description, can efficiently locate the price of the item they are interested in, for example, a new smartphone.3. 情况三:遇到不熟悉的词汇时- 例子5:While reading a literature passage with some archaic words. For example, in a passage from a Shakespearean play, when coming across words like “thou” and “thee”. By being aware of the context (the overall theme of the play, the relationship between characters) and the historical period of the writing, the reader can make an educated guess about the meaning. If the play is about a conversation between two friends in a love triangle, and “thou” is used by one character to address another, it can be inferred that it i s a form of “you” in an old - fashioned way.- 例子6:Reading a scientific research paper with specialized terminology. In a paper about genetics, terms like “allele” and “genotype” may be unfamiliar. The reader can use awareness of the subject area (genetics) and the overall flow of the paper. If the paper is discussing inheritance patterns, and “allele” is mentioned in the context of different forms of a gene, the reader can start to understand its meaning based on that context.4. 情况四:分析文章逻辑关系时- 例子7:In an argumentative essay. For example, an essay arguing for or against the use of renewable energy sources. The reader can be aware of the logical structure, such as the introduction stating the thesis (the main argument), the body paragraphs presenting supporting evidence or counter - arguments, and the conclusion summarizing the main points. By understanding this structure, the reader can betterevaluate the strength of the argument. If the body paragraphs lack relevant evidence or if the counter - arguments are not properly addressed, the reader can identify these flaws in the logic.- 例子8:Reading a mystery novel where the plot is full of twists and turns. By being aware of the logical connections between events, the reader can start to piece together the mystery. For instance, if a character's strange behavior is mentioned early on, and later on, a missing item is discovered, the reader can suspect that the character may be involved in the disappearance. The awareness of these logical relationships helps in predicting the outcome of the story.5. 情况五:理解文章文化背景时- 例子9:When reading a story set in a different culture. For example, a folktale from an African tribe. The reader needs to be aware of the cultural values, traditions, and beliefs of that tribe. If the story involves a character performing a certain ritual, understanding the cultural significance of that ritual (maybe it's a rite of passage or a way to appease the gods) helps in fully grasping the meaning of the story and the character's actions.- 例子10:Reading a travelogue about a foreign country. In a travelogue about Japan, when the author mentions concepts like “omotenashi” (the Japanese spirit of hospitality), the reader, by being aware of Japanese culture, can better understand the experiencesdescribed in the travelogue, such as the high - quality service in Japanese hotels and restaurants.三、个人观点English reading awareness strategies are extremely important for English learners. They not only help in improving reading comprehension but also enhance the overall reading experience. By being conscious of various elements in the reading process, readers can become more efficient and independent learners. These strategies can be developed over time through practice and exposure to different types of English texts. Teachers should also focus on teaching these strategies in the classroom, guiding students to be more aware of their reading habits and how to adjust them according to different reading tasks.。
中国装备制造业全要素生产率研究——来自世界五百强企业的证据
中国装备制造业全要素生产率研究中国装备制造业全要素生产率研究——来自世界五百强企业的证据徐小惠,李新英,克甝(新疆财经大学经济学院,新疆乌鲁木齐830012)摘要:我国对装备制造业一直以来都采取高度重视的态度。
尽管我国在各类生产要素上的高投入,但其投入与产出并不匹配,在研发上的巨大投入也没有带来相应的产出,且依然存在着核心零部件缺失、卡脖子问题。

Chemistry and International Center for Environmental Resources and Development,The City College of New York,New York,New York 10031,and Department of Chemistry,Queens College,CUNY,York,Flushing,New York 11367Sewage sludge-derived materials carbonized at tem-peratures between 400and 950°C were used for adsorption of sulfur dioxide from dry and moist air.The materials were characterized using sorption of nitrogen and thermal analysis.The sulfur dioxide capacity was measuredaccording to a laboratory-developed breakthrough test.It was found that the capacity of the adsorbents increases with increasing temperature of carbonization.It is likely that during carbonization at high temperatures such catalytic metals as calcium become active.They play a significant role in the SO 2removal process by neutralization of sulfuric acid formed as a result of oxidation of sulfur dioxide in wet conditions.Besides sulfuric acid,various sulfur-containing salts are formed.It was shown that,after their removal using water washing,the SO 2capacity significantly decreased.IntroductionAdsorption of sulfur dioxide on carbonaceous materials has been extensively studied (1-17).Activated carbon and activated carbon fibers have been found to be efficient adsorbents for the low-temperature removal of SO 2.It is believed that sulfur dioxide is adsorbed with two adsorption energies on activated carbons (3-12).The low energy,about 50kJ/mol,corresponds to weak physical adsorption,and the second,about 80kJ/mol,corresponds to chemisorption (11).The former process is likely to occur in small pores and is governed by microporosity and the pore size distribution of the activated carbon (12,13).The strong adsorption is related to the presence of oxygenated groups on the carbon surface (3,6,8,10,11,13),which are believed to be catalytic centers for sulfur dioxide oxidation to SO 3(14).Since usually the process is carried out in the presence of moisture and oxygen,sulfur dioxide is oxidized to sulfuric acid as the final product of the reaction.It was also found that three forms of adsorbed sulfur oxides could be present in such a situation.They are as follows:weakly adsorbed SO 2,physically adsorbed SO 3(after oxidation of SO 2),and strongly adsorbed H 2SO 4(5-13).The removal of the adsorption products from the carbon depends on the features of the carbon surface and thechemical nature of the oxidation products and their adsorp-tion energies (9).For example,the presence of strong basic groups on the surface strengthens the bond of sulfuric acid to the surface causing the low efficiency of its water extraction.On the other hand,an increase in surface acidity may result in enhancing both the adsorption of SO 2and the feasibility of water regeneration (9).The role of pore structure is not so well-defined (11,13).Overall,the capacities of activated carbon and carbon fibers under ambient conditions reported in the literature are of the order of a few miligrams to 100mg/g of carbon bed (10,18).Recently,we showed that materials obtained from sewage sludge-derived fertilizer can work efficiently as hydrogen sulfide adsorbents (19,20).Their origin is in biosolids,which are mixtures of exhausted biomass generated in the aerobic and anaerobic digestion of the organic constituents of municipal sewage along with inorganic materials such as sand and metal oxides.Since 6.9million t of biosolids (dry basis)was generated in 1998and only 60%was used beneficially (21),their conversion into useful materials is desirable.The problem of biosolid disposal is of major concern to environmentalists,especially in Europe where the standards for the heavy metal content of sewage sludge-derived fertilizers are 100times tighter than that in the United States (21).Municipal sewage sludge has been utilized in many ways.The most frequently applied are incineration,landfilling,road surfacing,conversion to fertilizer,compressing into building blocks,and carbonization (22,31).The last option is described in several patents (23-27).The resulting materials have been proposed to be used for removal of organics in the final stages of water cleaning (26)and removal of chlorinated organics (27).The materials obtained from carbonization of dewatered sewage sludge,with or without the addition of various activating agents,usually have surface areas between 100and 500m 2/g.Reports on their performance as adsorbents of acidic gases differ (28-31).For example,the capacity for the adsorption of SO 2reported by Lu was less than 10%of the capacity of Ajax activated carbon (31).When the performance for H 2S adsorption was compared,the capacity of the sludge-derived adsorbents was only 25%of the capacity of Calgon carbon,IVP 4x6(30).Our recent studies (20)showed that sludge-derived adsorbents have a higher capacity for hydrogen sulfide removal than coconut shell-based carbon,which is considered an alternative to the caustic impregnated carbons currently used in water treatment plants.The objective of this study is to determine the sulfur dioxide sorption capacity of sludge-derived adsorbents in comparison with the performance of coconut shell-based activated carbons.Differences in capacities result from differences in porosity,surface chemistry,and inorganic constituents of the adsorbents.All of these have an effect not only on the sorption capacity but also on the chemical nature of the oxidation products.Experimental SectionMaterials.The dewatered sewage sludge-derived product marketed as an organic fertilizer,Terrene,was obtained from the New York Organic Fertilizer Company (Bronx,NY)in the form of 3mm diameter granules with an approximate 5%water content.The chemical and structural properties of this sludge product are described elsewhere (19,20).It contains approximately 35%inorganic matter mainly in the form of iron,aluminum,and silicon oxides and carbonates and 60%organic matter.The sorbents used in this study were obtained*Corresponding author e-mail:tbandosz@;telephone:(212)650-6017;fax:(212)650-6107.†The City College of New York.‡Permanent address:Institute for Sorption and

&TECHNOLOGY93263Published on Web 07/06/2001by pyrolysis of Terrene at temperatures between400and 950°C in a nitrogen atmosphere in a fixed bed(horizontal furnace).The samples are referred to as SC400,SC600,SC800, and SC950(the numbers represent the pyrolysis temperatures of400,600,800,and950°C,respectively).For comparison,experiments were done using the as-received carbon manufactured from coconut shells by Waterlink Barnebey and Sutcliffe,S208.The sorbent was ground,and the granules were the same size as the carbonized Terrene(1-3mm).The prepared materials were studied as adsorbents for sulfur dioxide in the dynamic tests described below under dry and wet conditions.After the concentration of SO2in the effluent gas reached350ppm,the samples were considered as exhausted for sulfur dioxide adsorption,and each sample is identified by adding the letter“E”to its designation. Adsorbent samples not subjected to prehumidification(see below)are designated with the letter“D”.To investigate the effects of soluble inorganic salts,5g of initial or exhausted materials was washed in a Soxhlet apparatus for2days using300mL of water.The content of metals as calcium,iron,copper,and zinc was then evaluatedusing the procedure described below.Methods.SO2Breakthrough Capacity.Dynamic tests were carried out at room temperature to evaluate the capacity of the sorbents for SO2removal under two sets of conditions, wet and dry.For the former,adsorbent samples were packed into a glass column(length60mm,i.d.9mm,bed volume 6cm3)and prehumidified with moist air(relative humidity (RH)80%at25°C)for1h.The amount of water adsorbed was estimated from the increase in the sample weight.Moist air(RH80%at25°C)containing0.3%(3000ppm)SO2was then passed through the column of adsorbent at0.5L/min. The breakthrough of SO2was monitored using a Micromax monitoring system(Lumidor)with an electrochemical sensor. The test was stopped at the breakthrough concentration of 350ppm.The adsorption capacities of each sorbent in terms of gram of SO2per gram of carbon were calculated by integration of the area above the breakthrough curves and from the SO2concentration in the inlet gas,flow rate, breakthrough time,and mass of sorbent.For each sample, the SO2test was repeated at least twice.The determined capacities agreed to within4%.To determine the capacity of the dry adsorbent,the experimental conditions were the same as those in the wet run except for the absence of water vapor.The amount of weakly adsorbed SO2was evaluated by purging the adsorbent column with air at0.5L/min immediately after the break-through experiment.The SO2concentration was monitored until its concentration dropped to5ppm.The process took about1-2h depending on the type of adsorbent.Nitrogen Adsorption.Nitrogen adsorption isotherms were measured using an ASAP2010analyzer(Micromeritics, Norcross,GA)at-196°C.Before the experiment,the samples were degassed at120°C to a constant pressure of10-5Torr. The isotherms were used to calculate the specific surface area,S N2;micropore volume,V mic;total pore volume,V t;and pore size distribution.All the parameters were determined using Density Functional Theory(DFT)(32,33).The relative microporosity was calculated as the ratio of the micropore volume to the total pore volume.pH.A0.4-g sample of dry adsorbent was added to20mL of deionized water,and the suspension was stirred overnight to reach equilibrium.The sample was filtered,and the pH of solution was measured using an Accumet Basic pH meter (Fisher Scientific,Springfield,NJ).Thermal Analysis.Thermal analysis was carried out using TA Instruments thermal analyzer(New Castle,DE).The heating rate was10°C/min in a nitrogen atmosphere at100 mL/min flow rate.Determination of Iron,Zinc,and Copper.The quantities of iron,zinc,and copper removed from sludge-derived adsorbents during washing were determined using a Com-putrace716polarograph(Metrohm)in the differential pulse mode.A sample of0.03M triethanolamine was the electrolyte used for the determination of iron,whereas copper and zinc were determined using a0.05M NH3/NH4Cl buffer solution. In all cases the standard addition method was applied with 0.20mL of sample and10mL of supporting electrolyte.The differential pulse polarography peaks for iron,zinc,and copper were at-1.04,-1.07,and-0.30V vs SCE,respectively.Determination of Soluble Salt Content.The amount of metal ions in the leachate was determined using a titration with0.005M EDTA titrant and eriochrome black-T indicator. The amount of sulfate ion was determined by measuring the change in transmittance at520nm using a Palintest system photometer of the leachate after adding200mg of BaCl2to 10mL of leachate.The calibration curve was determined using known concentrations of sulfate.Conductivity and total dissolved solids(TDS)were measured using a Corning conductivity meter.The two calibration standards had conductivities of1413µS and12.88mS.The concentration of calcium in the leachate was measured using a calcium ion-selective electrode with a Fisher Accumet pIon meter (Fisher Scientific,Springfield,NJ).The electrode was cali-brated using a range of calcium concentrations from1×10-5to0.1M.Results and DiscussionSO2breakthrough curves obtained under dry and wet conditions are presented in Figures1and2,respectively.For comparison,the curve obtained for the coconut shell-based activated carbon(S208)is included.The values of the adsorbent capacities in milligram SO2per gram of adsorbent are given in Table1.The capacity of the wet adsorbent,and to a lesser extent that of the dry material,increased with carbonization temperature.For the high-temperature-carbonized dry sample,the SO2removal capacity is ap-proximately half that of the wet adsorbent;for these materials, water enhances the adsorption process.In the case of coconut shell-based activated carbon,the presence of moisture has little effect on its SO2breakthrough capacity.For the sludge-derived adsorbents,as suggested by the thermogravimetric results(below),water may react with oxides present in the inorganic matrix causing formation of surface hydroxyls(34, 35).These results also suggest that with increasing carbon-ization temperature new reactive oxides are formed,e.g., FIGURE1.SO2breakthrough curves for sludge-derived adsorbents with no prehumidification.The breakthrough curve for a coconut shell-derived activated carbon,S208,is included for comparison.32649ENVIRONMENTAL SCIENCE&TECHNOLOGY/VOL.35,NO.15,2001calcium oxide,from decomposition of calcium carbonate (18,36).Indeed,for the sample obtained at low temperature,SC400,the SO 2capacities under dry and wet conditions do not differ significantly.However,carbonization at 400°C would not be expected to completely dehydroxylate the surface inorganic oxides (35).With increasing carbonization temperature the differences in capacity between dry and wet conditions increase,suggesting changes in surface chemistry enhanced by the presence of moisture.It is interesting that all samples except SC400have similar capacities under dry conditions.This is probably related to changes in porosity.As described previously (19)and listed in Table 2,the values of structural parameters are ap-proximately double when the carbonization temperature exceeds 400°C.In Table 1,it is seen that the amount of water adsorbed after prehumidification increases with increasing carboniza-tion temperature.Sample SC400does not follow this trend,presumably because incomplete carbonization of organic matter at 400°C leaves hydrophilic functional groups on the carbonaceous deposit that retain water.The importance of the role of water in the formation of surface species is reflected in the trends in the amount of weakly adsorbed SO 2.For all samples run under dry condi-tions,roughly 20%of the adsorbed SO 2was removed by air purging.The absence of water precludes the formation of sulfuric acid in the pore system.However,it is possible thatSO 2forms sulfites through reactions with calcium oxide and carbonate.As noted previously (19,20),the sludge-derived samples contain 3-6%calcium.For samples run under wet conditions,air purging removes approximately the same amount of SO 2for all adsorbents except SC400.For all these sludge-derived materials,the site for weak physical adsorp-tion must be the same.About 5%of the SO 2is weakly adsorbed on the activated carbon,about 5times more than for the sludge-derived materials.This suggests differences in the mechanism of adsorption on conventional carbons and sludge-derived adsorbents.These differences in the mechanism are also reflected in the changes in pH of the samples.For the sludge-derived adsorbents,a relatively smaller decrease in pH is found after exhaustion,leaving a neutral or slightly basic material.However,a drastic acidification occurs with the activated carbon,presumably caused by the formation of sulfuric acid in wet conditions.To evaluate the chemical nature of sulfur-containing species,differential thermogravimetric (DTG)experiments were carried out in nitrogen.DTG curves are presented in Figures 3and 4.The peak maximum temperature and range provide information on the nature of the adsorbed species while the size of the peak is related to their amount.On the basis of reports in the literature on similar systems,the first peak at temperatures less than 150°C corresponds to the removal of physically adsorbed water and the weakly adsorbed SO 2(7,10,11,15-17).We have to emphasize here that this weakly adsorbed SO 2is adsorbed stronger than that removed during purging (the samples used for TA analysis are after the purging process).The second peak,between 150and 350°C,indicates the presence of strongly adsorbed sulfuric acid (7,10,15-17).The third peak,between 350and 550°C,corresponds to dehydroxylation of surface hydroxyl groups (35)and/or volatilization of salts such as FeSO 4(boiling point 480°C (37))that are formed by reaction of metal oxides present in the starting material with adsorbed sulfurous acid.The last peak,between 700and 900°C,results from the decomposition of inorganic salts such as calcium carbonate (decomposition temperatures of aragonite and calcite are 825and 900°C,respectively (37))and calcium sulfite.Comparison of the DTG curves for the initial samples and the exhausted samples carbonized at T >600°C run under dry conditions shows a significant increase in the size of the first peak.Since no water was present,this increase corre-sponds to the loss of the weakly adsorbed SO 2.For samples SC800DE and SC950DE,the peak assigned to the strongly adsorbed sulfuric acid is present,but its intensity is low because of the absence of water.It is likely that some water from the atmosphere was adsorbed on the surface during the storage process after SO 2adsorption and beforethermalFIGURE 2.SO 2breakthrough curves for sludge-derived adsorbents using prehumidification and moist conditions.The breakthrough curve for a coconut shell-derived activated carbon,S208,is

result of the reaction of SO 2under dry conditions with inorganic oxides or salts,the size of the peak near 800-900°C increases.For the exhausted samples run in the presence of moisture,the first peak is much larger than that for the dry-run samples.For the most carbonized material,SC950,which adsorbs the most water and SO 2,the peaks in the exhausted wet-run sample corresponding to loss of sulfuric acid and FeSO 4and/or CaSO 3are well-developed as compared to the starting material.These species are not formed at lower temperature of carbonization,suggesting a unique chemistry of the sludge sample prepared at 950°C,producing decomposition of calcium carbonate.DTG experiments done on the coconut shell-based carbon revealed a significant weight loss associated with the weakly adsorbed SO 2and a two-step weight loss between 200and 400°C.The first of these near 270°C results from the removal of surface-adsorbed H 2SO 4(7,17).The peak maximizing at 350°C probably corresponds to loss of sulfuric acid that is strongly bound to the surface of small pores in the carbon.A similar peak was found in a study of the oxidation of hydrogen sulfide on microporous activated carbons (38,39).In that study,the bonding with the surface was so strong that extensive water washing was not able to remove this sulfuric acid.In Table 3,we show the amount of sulfur dioxide adsorbed based on the breakthrough results (SO 2(BTh))(corrected for the air purge-desorbed amount)and the amount of SO 2in the form of S(IV)and S(VI)(S TA ).The latter was calculated for the dry runs,assuming that the first peak in the DTG curves represents the loss of SO 2and that the second peak represents the loss of H 2SO 4.A balance had been expected only for the dry runs and the activated carbon,because the first peak area cannot be corrected for the contribution ofthe loss of adsorbed water.In fact,it was found that the amount of water desorbed was smaller than the amount adsorbed.This apparent anomaly can be explained by the fact that some of the water adsorbed during prehumidifi-cation was consumed by hydration of SO 2and SO 3to produce sulfurous and sulfuric acids.These acids can further react with inorganic components of the adsorbents.Water was also consumed in hydroxylation of the surface.For the sludge-derived samples run under wet conditions,the amount of sulfur estimated from the first two DTGpeaksFIGURE 3.Differential thermogravimetric (DTG)curves for non-prehumidified sludge-derived adsorbents before and after exhaustion of sorption capacity with SO 2.The inset in the

from the SO 2breakthrough capacity.The material balance cannot be obtained by considering the contribution of water to the formation of sulfuric or sulfurous acid,salts,or surface hydroxides.It should be noted that for the samples run under wet conditions the weight loss between 700and 900°C increased after exhaustion.This indicates that a significant amount of sulfur is present in the form of salts,which decompose at temperatures higher than 700°C.As expected,the results are different for samples exhausted in dry runs where good balance was found due to the lack of water interference.Analysis of the nitrogen adsorption isotherms provides information on the spatial deposition of the surface products.The structural parameters calculated from the isotherms are presented in Table 2.During outgassing under high vacuum at 120°C,it is likely that the weakly adsorbed SO 2was removed from the pore system,leaving only sulfuric and sulfurous acid or sulfites and sulfates.The results show a decrease in the surface area and pore volume in the exhausted materials.This decrease is more pronounced for samples carbonized at the higher temperatures.For samples SC800and SC950,the volume of the micropores was reduced by almost 90%.In Table 2is also presented the hypothetical volume of sulfur products,V sulf ,deposited on the surface assuming that their density is 1.62g/cm 3.This density represents an average value between the density of condensed SO 2(1.40g/cm 3)and concentrated H 2SO 4(1.83g/cm 3).For the high-temper-ature-carbonized samples,this volume is comparable to the decrease in the volume of the micropores,which indicates the gradual filling of these pores with the products of surface reactions.A significant decrease in the sorption capacity was also observed for the coconut shell-based activated carbon.As shown by other researchers (5,13),in the presence of air and moisture,the adsorption of SO 2by activated carbon with a pH in the basic range is promoted by its conversion to sulfuric acid.That this capacity decrease is greater than the hypo-thetical volume of acid (assuming that all SO 2is oxidized to H 2SO 4of density 1.83g/cm 3)suggests that the acid is deposited at entrances to the pores.These changes are seen in the pore size distributions presented in Figure 5.The very narrow first peaks centered at about 6Åwith high intensities indicate the presence of fine microporosity,probably within the carbonaceous deposit of the initial materials (19).After the adsorption process,the volume in these pores is significantly decreased from the blocking of the pore entrances,as is shown in Table 2.Pores similar in size to the SO 2molecule should be especially active in the process of physical adsorption of sulfur dioxide (11).Indeed,the plot presented in Figure 6clearly shows that for the dry run samples,where a chemical reaction with surfaceoxides is less probable,a good correlation is found (R 2)0.88for the dry-run points)between the amount of SO 2adsorbed and total pore volume (points corresponding to SO 2adsorp-tion on peat-based Norit carbon,R2030,with V t )0.282cm 3/g are added to better demonstrate the trend observed).For the wet-run,the correlation is not as good,probably because of the catalytic effect of the surface of the adsorbents.The catalytic effect of the surface chemistry of the sludge-derived materials on the normalized capacity (capacity per unit surface area of adsorbent)is visualized in Figure 7.The normalized capacity of the sludge-derived adsorbents,especially those produced at higher temperature,is much larger than that of the activated carbon.The significantly higher activity of the surfaces of the adsorbents carbonized at 800and 950°C probably result from the combined effect of dehydroxylation of inorganic phase oxides and their solid-state reactions promoted at high temperature and reducing conditions.To investigate the effects of the inorganic phase,the initial and exhausted samples were subjected to Soxhlet extraction with water to remove water-soluble species.The weight changes produced by this treatment are summarized in Table 4.For the initial samples,although some water-soluble salts were removed from the surface,a small net weight increase was found.Presumably this is caused by the reaction of surface oxides with water to create hydroxyl groups.The affinity of sorbents toward water was changed after SO 2adsorption.Washing resulted in about 10%weight loss for samples,which adsorbed significant amounts of sulfur dioxide.This indicates that with increasingcarbonizationFIGURE 5.Pore size distributions for high-temperature-carbonized materials before and after exhaustion run under wetconditions.FIGURE 6.Dependence of the SO 2capacity on the total pore volume of the adsorbents.The line and the correlation coefficient refer to the data obtained under dry conditions (opencircles).FIGURE 7.Normalized capacity of the samples for SO 2under wet and dry conditions.VOL.35,NO.15,2001/ENVIRONMENTAL SCIENCE &TECHNOLOGY93267temperature the affinity of an inorganic phase toward reactions with sulfuric acid increased.This supports our hypothesis about the changes in the chemical states of metal oxides and salts at high temperature and the formation of sulfates or sulfite during SO 2adsorption in wet conditions.The concentrations of catalytically active metals such as iron,zinc,and copper in leachates were measured.The results revealed that concentrations of zinc,cooper,and iron were almost negligible (<0.001%the total weight loss).It follows that their amounts were too small to account for significant weight loss of exhausted samples.To find differences in the content of salts before and after SO 2adsorption,conductivity measurements,sulfate ion analysis,EDTA titrations,and potentiometric analyses of calcium were performed.The results are presented in Table 4.For the exhausted samples,the conductivities,total dissolved solids,total EDTA-titrateable metals,and sulfate and calcium concentrations are all larger for the exhausted materials than for the initial materials.This can only result from the conversion of adsorbed SO 2into water-extractable salts on the surface of the sludge-derived adsorbents.It is interesting that for SC950the amount of SO 42-present in the surface corresponds to the amount of SO 42-formed from SO 2adsorbed on the surface (4.50%as compared to 4.47%determined from SO 2adsorption).Another important finding is an excellent linear correlation between the amount of metal cations and the amount of sulfate ions present in the leachates from both initial and exhausted samples (R 2)0.985)(Figure 8).This suggests that the soluble salts are predominantly in the form of sulfates of divalent metal ions.Since the amount of calcium present in the leachates corresponds to about 60%of the amount of sulfate,the balance of the sulfate must be in the form ofsulfuric acid and associated with divalent metal ions other than calcium (as indicated above the amount of copper,zinc,or iron in leachates was negligible).This significant amount of calcium clearly indicates that CaO formed during car-bonization from CaCO 3present initially and subsequently partly hydrolyzed to Ca(OH)2are the main contributors to the removal of sulfur dioxide through their reaction with sulfuric acid to form soluble sulfates (36).Further support for this is the fact that,after the exhausted samples were washed,the SO 2breakthrough capacity decreased to 15and 12mg/g for SC800and SC950,respectively.It is interesting that the breakthrough capacity values obtained for both initial and exhausted samples after extensive washing are similar.This suggests that after removal of chemically active salts and oxides some SO 2can be adsorbed in the carbon pore system.Since the structural parameters remain similar,the adsorption of SO 2is comparable.The results presented here imply that at least two types of active sites for SO 2adsorption are present on the surface of the sludge-derived adsorbents.The first is metal oxides or hydroxides in the mineral matter,and the second is active sites on the carbon surface.The amount of the metallic active sites can be estimated from the increase in the amount of water-extractable ions from the initial to the exhausted.The dependence of the amount of SO 2adsorbed per unit surface area on the increase in sludge-derived adsorbent soluble ion content per unit surface area is shown in Figure 9.Since the capacity of the adsorption catalytic system is expected to reach a limiting value when all active sites are exhausted,we fitted the results assuming that a Langmuir -Hinshelwood surface reaction model is followed (40).The results presented in this paper demonstrate that sewage sludge-derived materials can work efficiently as adsorbents for sulfur dioxide from moist air.The SO 2on the surface of these materials is first physically adsorbed,oxidized to SO 3,and then converted into sulfuric acid.The acid reacts with inorganic oxides and/or salts to create soluble sulfates.Calcium oxide is the principal reactant for neutralization of sulfuric acid in the pore system of the adsorbents.The reaction proceeds until the active inorganic species are consumed.Removal of salts from the surface significantly decreases the adsorbent capacity,leaving the possibility of physical adsorption and oxidation to SO 3.The samples carbonized at higher temperatures are more active because of the presence of chemically active calcium oxides and high dispersion of catalytic metals.TABLE 4.Weight Change on Leaching,Leachate Conductivity,Total Dissolved Solids (TDS),EDTA-Titrateable Metal Cation Content (Me n +),SO 42-Content,and Calcium

stata中test用法 -回复
stata中test用法-回复Stata中的`test`命令是进行假设检验的一种常见方式。
它可以用于测试统计模型的参数约束条件,评估是否满足特定的等式或不等式关系,以及进行模型之间的比较。
一、基本语法和选项在Stata中,`test`命令的一般语法如下:test [hypothesis] [options]其中,`hypothesis`表示待检验的假设,可以是参数的等式或不等式。
`options`则是一些可选项,可用于指定是否进行异方差性或序列相关性的校正、计算百分位数、自定义报告格式等等。
二、参数约束条件的检验`test`命令常用于检验统计模型中的参数约束条件。
通常,我们希望确认某些模型参数是否为零,或者是否满足特定的等式关系。
`test`命令提供了一种简便的方式来进行这些检验。
例如,假设我们拟合了一个多元线性回归模型,包含了两个解释变量x1和x2,以及一个因变量y。
我们想要检验x1和x2的系数之间是否存在显著差异。
可以使用如下命令:test x1 = x2该命令将进行一个t检验,检验`x1`和`x2`系数之间是否存在显著差异。
如果返回的p值小于事先设定的显著性水平(通常为0.05),则可以拒绝原假设,认为两个系数不相等。
三、统计模型的比较除了参数约束条件的检验,`test`命令还可以用于比较不同的统计模型。
例如,我们拟合了两个不同的多元线性回归模型,模型1和模型2,分别采用了不同的解释变量和函数形式。
我们希望确定哪个模型更好。
可以使用如下命令:test [model1] = [model2]`model1`和`model2`表示两个模型的表达式。
该命令将进行一个F检验,检验模型1和模型2的显著性差异。
返回的p值小于0.05时,我们可以认为两个模型在统计上存在显著差异,即一个模型相对于另一个模型更好。
四、其他应用除了上述常见的应用场景,`test`命令还可以用于更复杂的假设检验,例如多个参数的组合检验、异方差性和序列相关性的校正等。

fstpd计算公式(一)
fstpd计算公式(一)FSTPD计算公式简介FSTPD(Fast Software Testing Performance Diagram)是一种用于评估软件测试性能的方法。
通过使用一系列计算公式,可以快速量化软件测试的效果和质量。
下面列举了几个与FSTPD相关的计算公式,并提供了解释和示例。
时间效率指标1. 测试速度测试速度是指完成一个测试用例所需的时间。
可以通过以下公式计算:测试速度(TC) = 测试用例执行的时间总和 / 测试用例的数量示例:如果执行100个测试用例的总时间为200秒,则测试速度为2秒/用例。
2. 测试生产力测试生产力是指在单位时间内能够执行的测试用例数量。
可以通过以下公式计算:测试生产力(TP) = 测试用例的数量 / 测试用例执行的时间总和示例:如果在60秒内执行了30个测试用例,则测试生产力为个用例/秒。
资源利用率指标1. 测试资源利用率测试资源利用率是指测试资源的有效利用程度。
可以通过以下公式计算:测试资源利用率(TRU) = 有效使用测试资源的时间总和 / 测试用例执行的时间总和示例:如果在200秒的测试时间中,有150秒是有效利用测试资源,则测试资源利用率为。
2. 测试用例复用率测试用例复用率是指被多次执行的测试用例的比例。
可以通过以下公式计算:测试用例复用率(TCR) = 被多次执行的测试用例数量 / 总测试用例数量示例:如果总共执行了100个测试用例,其中有60个是被多次执行的,则测试用例复用率为。
质量评估指标1. 测试缺陷发现率测试缺陷发现率是指在测试过程中发现的缺陷数量与发现时间的比例。
可以通过以下公式计算:测试缺陷发现率(DFR) = 发现的缺陷数量 / 测试用例执行的时间总和示例:如果在200秒的测试时间中发现了10个缺陷,则测试缺陷发现率为个缺陷/秒。
2. 缺陷密度缺陷密度是指在软件中每个模块或代码行中的缺陷数量。
可以通过以下公式计算:缺陷密度(DD) = 缺陷数量 / 软件模块或代码行数示例:如果在一个包含10000行代码的软件中发现了100个缺陷,则缺陷密度为个缺陷/行。
rstdio拟合weibull失效率函数
rstdio拟合weibull失效率函数在可靠性工程中,失效率函数是一个非常重要的概念。
失效率函数描述了一个系统在运行一段时间后,出现故障的概率。
其中,Weibull失效率函数是一种常用的失效率函数,它可以用来描述许多不同类型的故障模式。
在本文中,我们将介绍如何使用R语言中的rstdio包来拟合Weibull失效率函数。
rstdio是一个用于可靠性分析的R语言包,它提供了许多用于可靠性分析的函数和工具。
我们需要准备一些数据来拟合Weibull失效率函数。
我们可以使用rstdio包中的weibull.fit函数来拟合数据。
该函数需要两个参数:一个是故障时间数据,另一个是故障状态数据。
故障时间数据是指系统运行到故障发生的时间,故障状态数据是指系统是否发生故障。
如果系统发生故障,则状态为1,否则为0。
下面是一个示例代码,用于生成一些随机数据来拟合Weibull失效率函数:```{r}library(rstdio)set.seed(123)time <- rweibull(100, shape = 2, scale = 100)status <- rbinom(100, size = 1, prob = pweibull(time, shape = 2,scale = 100))```在上面的代码中,我们使用rweibull函数生成100个符合Weibull 分布的随机数作为故障时间数据,然后使用rbinom函数生成100个随机数作为故障状态数据。
我们使用pweibull函数来计算每个时间点的故障概率,然后使用rbinom函数来生成故障状态数据。
接下来,我们可以使用weibull.fit函数来拟合数据:```{r}fit <- weibull.fit(time, status)```在上面的代码中,我们将故障时间数据和故障状态数据作为参数传递给weibull.fit函数,然后将拟合结果保存在fit变量中。
