30sGood afternoon, everyone. The title of the paper is Visible Microspectroscopy for Diagnosis of Gastric Precancer. Its author is Liu Yong from Department of Physics, Zhao qing University. It’s presented by Li Mengfan from CAS, Hefei Institutes of Physical Science. You can know more about cancer and the new method to diagnose gastric precancer after reading this paper.58sCancer is very common among human beings. It is mostly related to the habit of the patients, the job, the environment, the drinking water and the soil matters, too. If a person is affected by certain bacteria, he may also get gastric cancer. Bad habits like smoking, drinking, mental tension, eating improperly and living irregularly increase the possibility of having cancer. Before specific treatment, the doctor should make sure whether the patient has cancer and where the focus is. The method used to diagnose cancer and locate thecancerous area is very important.42sBefore we design a method to diagnose cancer, we should know more about cancer like where it starts and what it causes.Firstly, about 90% of the human’s cancer start from the epithelial layer of skin, internal organs and tubular organs in the body. Secondly ,cancer usually accompanied by the changes of organization structure in the cell level.So, the changes which appear in the structure of organization and chemical composition provides important evidence for diagnosis of precancer.42sNormal method to diagnose gastric precancer is Reflectance spectroscopy. It’s very prospective in early diagnosis of cancer and is commonly used these years.One of the most common technology is diffuse reflectance visible spectroscopy, it can acquire the approximate information of the target tissue. This method is low cost, fast and non-invasive, it provides important means for diagnosis of malignant damage of organization of human organs. However, there are also some disadvantages of this method which need to be improved.55sThis is the system of diffuse reflectance spectroscopy, the light beam emitted from the tungsten halogen lamp is guided into the integral ball by the source fiber. The light come out of the integral ball irradiate the standard board, the reflected light of the standard board is treated as the background. Then take target tissue substitute for the standard board, and scan the reflected light of it. The reflected light spectra of the gastric tissue mucosal layer and the submucosa layer is guided into the spectrometer by the collector fiber. The spectrometer and the computer is connected by USB, spectrum can be processed using computer.36sFirst of all, only average visible spectrum of the target tissue can be acquired, it means that the docters cannot make out the location of the cancerous tissue precisely.What’s more, the device is easy to be affected by changes of optical path length induced by different set-up of prober and the variation of hemoglobin concentration due to the pressure between prober and tissue.50sTo avoid the problems of the commonly used techniques, diffuse reflectance visible spectroscopy, scientists do a lot of researches to find out a new way to diagnose precancer.The new method is Visible Microspectroscopy. The visible microspectroscopic measurement device is accomplished on the basis of fiber confocal microscope, its 3-d imaging principle devote to the optical tomography ability of the system.The visible microspectrum of cancerous and normal tissue can be analysed andcontrasted, so it’s more useful than the normal method.45sThis is the structure of the visible microspectroscopy device .The fiber coupler can separate the lighting beams from the signal beam. The two lens can focus the light on the tissue ,The 3-D electronic controlled platform move along the direction of optic axis, so that the device can acquire the visible microspectroscopy signal of the sample in different depth, precisely locate the boundary of the cancerous tissue.The signal measured from different position can be stored in the computer after analysed by the spectrometer.31sThis is the spectrum chart of the normal tissue and cancerous tissue, they are analyzed by the spectrometer before being transmitted to the computer. The upper chart is the visible spectrum of normal tissue, it is regular. Contrasting to this, in the nether chart, the spectrum of the cancerous area shows that the strength of reflected light grows as the wave length grows.49sIn comparison with the normal method, there are a lot of advantages of the new method.Firstly, the structure of visible microspectroscopy device is very simple. The main parts consist of source, fiber coupler, 3-D electronic controlled platform, spectrometer and the computer.Secondly, the 3-D space microspectrum can be acquired , which can help the doctors efficiently make out whether the gastric tissue is cancerous.What’s more, the optical tomography ability enabled the device to precisely locate the edge of the cancerous area.32si.In conclusion, the main goal of this research is to find a new way to diagnose thegastric precancer.ii.The spectrum of the normal and cancerous gastric tissues which can be measured by visible microspectroscopy in cell level is the central idea .iii.This new method can obtain the cell level information, and is not affected bychanges of optical path length and hemoglobin concentration.50si. The device is very simple, so it can have a small size, which can reduce the sufferings of patients.It can efficiently make out whether the tissue is canceration.ii. Besides, the 3-D space microspectrum and optical tomography ability can make the device accurately distinguish the cancerous tumor area from the normal tissue in cell level, thus the boundary of the cancerous tissue can be ascertained accurately.iii. The result of the research shows that this device may be used to non-invasively diagnosis of early gastric cancer.20sThis device is only researched in the lab, there are still a lot of works to do to make this device applied into practice. So, s pecial design of this device should be made which can be applied to the medical diagnosis.给大家推荐一个英语微信群Empty Your Cup英语微信群是目前学习英语最有效的方法，群里都是说英语，没有半个中文，而且规则非常严格，是一个超级不错的英语学习环境，群里有好多英语超好的超牛逼的人，还有鬼佬和外国美眉。

结构性
结构是文章的框架和支撑，是谋篇布局。学术英语写作的结构是显而易见的， 例如，一般的短文呈现开篇-主体一结论的结构，而科研论文则呈现开篇一方 法一结果-讨论或开篇-方法一结果-讨论一结论的结构。 2、论述性。 学术英语写作具有鲜明的逻辑性，中心思想需要以明确的公式化的方式进行表 达，关于中心思想的论述需要符合逻辑发展的过程，结论则自然是基于逻辑的 发展才能成立。
结构性
3、分析性。 学术英语的分析性是指在对中心思想进行论述、论辩或论证的过程 中需要使用分析的方式方法，包括进行解释、给出理由、验证或预 期可能产生的后果;进行比较、对照和评价;采取全面辩证的观点。

This paper is structured as follows
content
abstract
✓ In this paper we describe how rolling stock and passenger connections in a cyclic railway timetable can be modeled in a flexible way within the model for the Periodic EventScheduling Problem (PESP). Usually, PESP models assume that the constraints for rolling stock or passenger connections specify in detail which trains should connect with each other.
✓ 然而，本文中所提出的灵活性允许模型去选择在动车组交 路接续和旅客接续中列车的接续。依据特定过程的时间变 量得到最小到发列车配对，我们用它来表达接续时间。
abstract
✓ We also describe an abstract framework demonstrating that, under certain conditions, the extra flexibility can be modeled purely in terms of PESP constraints. The concept of flexible rolling stock and passenger connections is illustrated by an example based on three intercity lines of Netherlands Railways.
✓ 我们也描述一个简明的框架证明，在特定情况下，可以只 依据PESP约束表示出其他额外的灵活性。关于灵活的动车 组交路接续和旅客接续概念，我们用一个基于荷兰铁路三 条城际线路的例子来说明。
Key words
✓ cyclic railway timetabling; ✓ rolling stock and passenger connections; ✓ PESP
✓ However, in this paper we describe how the rolling stock and passenger connections can be modeled in a flexible way within the PESP model, thereby leading to better timetables with respect to passenger connection times, running and dwell times, or the number of train compositions required to operate the timetable.
Sentences pattern
✓ Note that … 注意… （表示解释说明） ✓ With respect to 关于，至于 ✓ In terms of 依据，根据 ✓ For the sake of clarity，…. 清晰起见，….
Summary and conclusions
✓ In this paper we illustrated that a priori fixing the rolling stock or passenger connections in a PESP model may lead to suboptimal solutions if the involved trains are operated more than once per hour. It may even lead to infeasibility for instances where a feasible solution would exist if the connections were selected in the right way. These results were illustrated by a case based on three intercity lines of Netherlands Railways, the largest operator of passenger trains in the Netherlands.
✓ 在本章，我们依据每个方向有两列车的案例的约束图中特 定圈的圈变量介绍以整数线性g sentences 2
✓ Furthermore, when minimizing either of the three objectives, the other objectives are taken into account with a tiny weight in order to minimize them, given the minimal value of the main objective.
✓ 文章中我们举例说明了PESP模型中，如果一小时开行一列以上列车 的话，一个提前固定的动车组交路和旅客接续可能导致次优解。而 且在存在最优解且接续选择正确的情况下，在案例中有可能导致不 可行解。这些结果在案例中得到验证，案例是基于荷兰铁路的三条 城际线路，荷兰铁路是荷兰最大的旅客列车运营商。
Summary and conclusions
✓ Using the well-known method for translating pairs of disjunctive constraints in a PESP model into pairs of conjunctive constraints, we described the rolling stock and passenger connections in a flexible way so that the model can choose between the different options.
introduction
✓ The Periodic Event-Scheduling Problem (PESP), introduced by Serafini and Ukovich (1989), can be used for scheduling a number of periodically recurring events. Railway operators use the PESP model to develop cyclic timetables. The usual PESP model for cyclic railway timetables uses fixed rolling stock and passenger connections to develop the timetable.
✓ 运用常用的方法将PESP模型中的单个约束转换成连续的约 束，我们用一种灵活的方式描述动车组交路和旅客接续使 得模型可以有不同的选择。
Summary and conclusions
✓ For the case of two trains per hour in both directions, we expressed the number of train compositions needed to operate the timetable in terms of the cycle variables of certain cycles in the constraint graph. For the more general case, we expressed the total connection time in a matching of the arriving and departing trains in terms of certain process time variables, based on the method described by Villumsen (2006). This can then be used to determine the number of train compositions needed to operate the timetable.
✓ 此外，当最小化三个目标中的任何一个时，另外的几个目 标就考虑赋给它们很小的权值以最小化他们，得到主要目 标的最小值。
Long sentences 3
✓ Now we want to find an expression for the total connection time between the arrivals and departures that connect with each other in station B if the connections in station B are still to be determined.
