Part Two Translation

Directions: Read the following passage carefully and translate it into Chinese. Write your translation clearly in the spaces provided below.

What’s in a name?

For thousands of years, humanity has classified the living thins of this world in much the same fashion; by their appearance. If it looks like a duck, walks and quacks like a duck, then it is a duck. But tackling millions of species in this way has proven to be a recipe for confusion. As scientists have found to their cost, what looks like a duck may in fact be a goose.

More recently, genetic techniques have been applied, particularly for distinguishing the more difficult-to-identity species such as viruses and bacteria by comparing pieces of DNA. Might this approach be more generally applicable? Paul Hebert and his colleagues inCanadathink it might be. Just as barcodes

and the “universal product code” numbering scheme uniquely identify differe nt items at a supermarket checkout, they suggest that some stretches of DNA could perform a similar function in living things. In a paper just published in Proceedings of the Royal Society B, they discuss how long such a genetic barcode needs to be, and where it might be found.

A universal product code found on the high street consists of a string of 11 digits, each of which is one of ten numerals, providing 100 billion unique combinations. Genetic material, however, uses a quaternary, rather than a denary, coding system. In theory, it would only be necessary to sample 15 of those letters to create one billion unique codes.

In practice, however, the characteristics of DNA mean that 15 letters are not enough. Unlike the arbitrary numbers of a universal product code, the letters of DNA are not random, because they code for something that a biological meaning.

最新材料力学实验参考教学教材

实验一、测定金属材料拉伸时的力学性能 一、实验目的 1、测定低碳钢的屈服极限s σ,强度极限b σ,延伸率δ和面积收缩率ψ。 2、测定铸铁的强度极限b σ。 3、观察拉伸过程中的各种现象,并绘制拉伸图(l F ?-曲线)。 二、仪器设备 1、液压式万能试验机。 2、游标卡尺。 三、实验原理简要 材料的力学性质s σ、b σ、δ和ψ是由拉伸破坏试验来确定的。试验时,利用试验机自动绘出低碳钢拉伸图和铸铁拉伸图。对于低碳材料,确定屈服载荷s F 时,必须缓慢而均匀地使试件产生变形,同时还需要注意观察。测力回转后所指示的最小载荷即为屈服载荷s F ,继续加载,测得最大载荷b F 。试件在达到最大载荷前,伸长变形在标距范围内均匀分布。从最大载荷开始,产生局部伸长和颈缩。颈缩出现后,截面面积迅速减小,继续拉伸所需的载荷也变小了,直至断裂。 铸铁试件在极小变形时,就达到最大载荷,而突然发生断裂。没有流动和颈缩现象,其强度极限远低于碳钢的强度极限。 四、实验过程和步骤 1、用游标卡尺在试件的标距范围内测量三个截面的直径,取其平均值,填入记录表内。取三处中最小值作为计算试件横截面积的直径。 2、 按要求装夹试样(先选其中一根),并保持上下对中。 3、 按要求选择“试验方案”→“新建实验”→“金属圆棒拉伸实验”进行试验,详细操 作要求见万能试验机使用说明。 4、 试样拉断后拆下试样,根据试验机使用说明把试样的l F ?-曲线显示在微机显示屏 上。从低碳钢的l F ?-曲线上读取s F 、b F 值,从铸铁的l F ?-曲线上读取b F 值。 5、 测量低碳钢(铸铁)拉断后的断口最小直径及横截面面积。 6、 根据低碳钢(铸铁)断口的位置选择直接测量或移位方法测量标距段长度1l 。 7、 比较低碳钢和铸铁的断口特征。

参考文献实验报告格式

参考文献实验报告格式 在这个阶段中,学生根据已有知识的经验,通过演绎、归纳、推理而提出的假设,不少带有猜测的性质。此时教师要引导学生积极作出假设,不应压抑学生的思维,不管是对是错,都不要忙于作出评价。下面是精心收集的参考文献实验报告格式,希望能对你有所帮助。 一、实验目的 1.干涉的实验目的 1)组装调节迈克尔逊干涉仪,观察点光源产生的非定域等厚、等倾干涉条纹记录。 2)观察干涉条纹反衬度随光程差变化。了解光源干涉长度的意义,检查防震台稳定性。 3)比较平面波和球面波产生干涉条纹的区别。 2.衍射的实验目的 1)验证夫琅禾费衍射图样的若干规律。 2)掌握测量利用光电元件测量光强的方法。 3)用Matlab模拟夫琅禾费衍射现象。 二、实验仪器 1.干涉实验仪器 He-Ne激光器,反射吧镜,衰减器,分光光楔,扩束器,显微物镜镜头,光阑,CCD,配备相关软件的计算机,白板。 2.衍射实验仪器

He-Ne激光器,反射镜,双凸透镜,狭缝,圆孔,一维光栅,衰减器,CCD,计算机。 三、基本原理 1.迈克尔逊干涉仪的非定域干涉条纹 本仪器是用分裂振幅的方法产生双光束干涉以实现光的干涉。从激光器岀射的光束经过准直扩束器系统,形成一束宽度合适的平行光束。这束平行光射入分光棱镜之后分为两束。一束由分光棱镜反射后到达发射镜,经反射后透过分光棱镜,形成岀射光束,这是第一光束;另一束透过分光棱镜,到达反射镜,经过反射后再次到达分光棱镜,形成反射光束,这是第二束光。在分光棱镜前方两束光的重叠区域放上CCD。 干涉原理,如有图所示,其中S为单色点源,M1、M2为互相垂直放置的平面反射镜。BS为分束镜,放在M1M2法线的交点上,并分别与M1、M2成45°角。电光源S发出球面波经BS的镀膜层分为两束光。这两束光分别经M1、M2反射又回到BS,在BS上透过和反射的这两束光在BS的右侧空间形成一非定域的干涉场。屏幕放在干涉场中垂直于光束方向,在屏幕 上可以看到干涉条纹。M2’与M1平行时(及M2与M1相互垂直),产生圆形干涉条纹,当M2’与M1之间有一定小的倾角时,屏幕上的干涉条纹不再是圆形的封闭曲线,而变成弯线或是接近直线(实际上是双曲线或椭圆的一部分)。 圆心条纹中心处的光强取决于M1M2相对的距离d,即:

Fluorescent in situ Hybridization on Mitotic Chromosomes of Mosquitoes. J. Vis. Exp. (67), e4215, doi:10.3791/4215 (2012). Abstract Fluorescent in situ hybridization (FISH) is a technique routinely used by many laboratories to determine the chromosomal position of DNA and RNA probes. One important application of this method is the development of high-quality physical maps useful for improving the genome assemblies for various organisms. The natural banding pattern of polytene and mitotic chromosomes provides guidance for the precise ordering and orientation of the genomic supercontigs. Among the three mosquito genera, namely Anopheles, Aedes, and Culex, a well-established chromosome-based mapping technique has been developed only for Anopheles, whose members possess readable polytene chromosomes 1. As a result of genome mapping efforts, 88% of the An. gambiae genome has been placed to precise chromosome positions 2,3 . Two other mosquito genera, Aedes and Culex, have poorly polytenized chromosomes because of significant overrepresentation of transposable elements in their genomes 4, 5, 6. Only 31 and 9% of the genomic supercontings have been assigned without order or orientation to chromosomes of Ae. aegypti 7 and Cx.quinquefasciatus 8, respectively. Mitotic chromosome preparation for these two species had previously been limited to brain ganglia and cell lines. However, chromosome slides prepared from the brain ganglia of mosquitoes usually contain low numbers of metaphase plates 9. Also, although a FISH technique has been developed for mitotic chromosomes from a cell line of Ae. aegypti 10, the accumulation of multiple chromosomal rearrangements in cell line chromosomes 11 makes them useless for genome mapping. Here we describe a simple, robust technique for obtaining high-quality mitotic chromosome preparations from imaginal discs (IDs) of 4th instar larvae which can be used for all three genera of mosquitoes. A standard FISH protocol 12 is optimized for using BAC clones of genomic DNA as a probe on mitotic chromosomes of Ae. aegypti and Cx.quinquefasciatus, and for utilizing an intergenic spacer (IGS) region of ribosomal DNA (rDNA) as a probe on An. gambiae chromosomes. In addition to physical mapping, the developed technique can be applied to population cytogenetics and chromosome taxonomy/systematics of mosquitoes and other insect groups. Video Link The video component of this article can be found at https://www.360docs.net/doc/0415182271.html,/video/4215/ Protocol 1. Chromosome Preparation Mosquito larvae were reared using a standard protocol described in Methods in Anopheles Research available at the website of the Malaria Research and Reference Reagent Resource Center(MR4) 13. The temperatures of mosquito rearing were modified to provide the highest number of chromosomes in imaginal discs and lowest mortality of the larvae. The stages of mosquito larvae development were determined based on the sizes of their head capsules 13. 1.Hatch mosquito eggs at 28 °C, and after 2-3 days, transfer 2nd or 3rd instar larvae to 16 °C for Ae. aegypti and Cx. quinquefasciatus and to 22 °C for An. gambiae. 2.Place 4th instar larvae on ice for several minutes for immobilization. 3.Transfer larva to a slide with a drop of cold hypotonic solution (0.5% sodium citrate or 0.075 M potassium chloride), and place it under the stereo microscope. 4.Select larva with oval IDs (Figure 1B) for further dissection. 5.Decapitate larva, and cut the cuticle from the ventral side of the larval thorax using dissecting scissors (Figure 2A). Make additional cut in second or third abdominal segment to dissect the gut from the larva. The directions of the cuts are shown by arrows. 6.Open the cuticle, and remove the gut and fat body from the larva. Remove the hypotonic solution from the slide using filter paper, and add a fresh drop of hypotonic solution directly to the IDs (Figure 2B). Keep larva in hypotonic solution for 10 min at RT. 7.Remove hypotonic solution using filter paper, and apply Carnoy's solution (ethanol/acetic acid in 3:1 ratio). After adding fixative solution, IDs immediately turn white and become easily visible under the microscope (Figure 2C). https://www.360docs.net/doc/0415182271.html,ing dissecting needles, remove IDs from the larva (Figure 2D), and transfer them to a drop of 50% propionic acid. Remove any other tissues, such as the gut and fat body, from the slide. Cover IDs with an unsiliconized 22x22 cover slip, and keep for 10 min at RT. 9.Cover the slide with filter paper, and squash the tissue by tapping the eraser of a pencil on the perimeter of the cover slip. 10.Briefly analyze the quality of the slide using the phase-contrast microscope at 100x or 200x magnification (Figure 3). Preparations with >50 chromosome spreads can be considered suitable for FISH.
