"Evolution" was first used in Preformationism and then in Epigenesis, respectively, to describe the unfolding of preexisted organic structure and the recapitulation of the forms of lower animals by the embryo of higher animals. The n the meaning of species change was added to it in the beginning of the nineteenth century.

"Evolution"一词先后被用在胚胎学的预成论和后成论中，分别用来描述预先存在的有机体结构的展开以及高等动物胚胎对低等动物形式的重演。19世纪初它又被添加上了物种改变的含义。

1引言调制传递函数是对卫星光学相机成像性能进行评估的一个重要参数，该函数反映了相机的两个重要特性，即所成图像的分辨率和对比度，它是目前评价光学相机空间特性最好的参数[1]。

On the one hand,Dai's work can be read as a picaresque,exotic, ethnographical,absurd,satiric,or chivalrous novel in the Western tradition.On the other hand,it can be equally read as a Chinese novelin the tradition of Lu Xun,in its portrayal of modern China.

一方面，戴思杰的小说可以被读成西方传统中的流浪汉小说，异乡奇观小说，少数民族小说，荒诞的讽刺、骑士风度小说；另一方面，哪怕此书是用法语写成，它对现代中国的描写，则是一本十足的中国小说，继承了鲁迅的传统。

At the time of final settlement following the end of the year, no recomputation and reconversion need be made in respect of income in a foreign currency for which tax has already been paid on a quarterly basis; only that portion of the foreign currency income of the entire year for which tax has not been paid shall, in respect of the computation of taxable income, be converted into Renminbi according to the exchange rate quotation on the last day of the tax year.

第十五条企业所得为外国货币的，在依照税法第十五条规定分季预缴所得税时，应当按照季度最后一日的外汇牌价折合成人民币计算应纳税所得额；年度终了后汇算清缴时，对已按季度预缴税款的外国货币所得，不再重新折合计算，只就全年未纳税的外国货币所得部分，按照年度最后一日的外汇牌价，折合成人民币计算应纳税所得额。

To study the characteristics of the mesenchymal cells of ameloblastic fibrosarcoma, three cases of AFS were studied immunohistochemically and ultrastructurally.

为探讨成釉细胞纤维肉瘤间叶细胞的本质及特征，作者采用免疫组化和电镜技术，对3例AFS间叶细胞进行了研究，并与6例成釉细胞纤维瘤进行比较。

After the analysis it was concluded that the mean velocity fluctuations of the strata under Jidike Group in this working area could be divided into three zones: the minor velocity fluctuation zone in southern Dalaoba tectonic belt, the steep velocity fluctuation zone of the foreslope in middle YK structure and the zone from the bowtype thrusting tectonic belt in northern Qiulige to the minor velocity fluctuation zone in YK tectonic zone. On the basis of a good command of the regular patterns of the velocities in vertical and horizontal dimensions in the investigating area, the stack velocity was interpreted in a interactive mode by using the Depthteam Express modelling package of the Landmark system, converting the stack velocity into mean velocity by means of Dix formula. Based on the well drilling layering data, the velocity correction was executied to get the final corrected velocity model by using the Kriging Correction. By using this velocity model, we did the time to depth conversion and obtained the final depth structural map. After mapping by using the variable velocities, we came in for the display of the tectonic map of the seismic data.

经研究认为本区的吉迪克组以下层位平均速度变化可分成三个变化区域：南部大涝坝构造带速度变化平缓区；中部亚肯构造前缘斜坡区速度变化强烈区；北部秋里塔格弧形逆冲构造带前缘至亚肯构造带速度变化平缓区，在撑握工区速度纵、横向变化规律基础上，应用Landmark解释系统Depthteam Express速度建模软件包对迭加速度进行交互解释，利用DIX公式把迭加速度转换成平均速度，根据区内钻井分层数据采用克里金校正方法进行速度校正，得到最终校正后的速度模型，用此速度模型进行时深转换，得到最终的深度构造图，此次变速成图后，得到地震资料构造图显示。

Results The ozone could cause death to flyblow and some of the pupa and adult of housefly and make the pupa of housefly eclosion restrain and filial generation of housefly nervure variation.

结果O3对家蝇卵有致死作用；O3对蛹有一定杀伤作用，使羽化受到明显抑制，羽化时间相对延长；O3对成蝇有一定致死作用，存活的家蝇进行传代，子代F1、F2、F3均出现短翅和翅脉变异，但对子代性别无明显影响。

Only if educators construct and create the actual education, the educatees can select something from it. The future education mainly depends on what educational choice the educators make presently. It means, the actual education is not the foreordination, but is decided by the educators'constructing and creating.

受教者作为参与教育的重要主体，他们对教育的需求，无疑对教育的实施起着重要的制约、影响的作用，但受教者对教育的制约和影响是从接受教育的向度，从既成的教育之中选择自己所需要的教育(包括学校、教师、课程等诸般教育资源)和向施教者提出自己所需要的教育，由于受教者不是教育的实施者，其对教育的制约和影响必须通过施教者得以体现，现有的教育和施教者的存在乃是受教者选择接受什么教育和如何接受教育的前提。

Methods From January to April of 2006, the fundus area within three degrees from the central fovea from 6 normal volunteers were checked using a tailor-made adaptive optics system.

2006年1到4月间，我们运用改进后的自适应光学成像系统对6名18~21岁正常健康成年人进行了眼底黄斑部中心3度范围之内视网膜的成像试验。

The system could provide the real-time information on occurrence of more than 60 different kinds of diseases and pests in wheat, corn, rice, potato, sorghum and millet of China as well as diagnosing, knowledge providing and short-term controlling decision for nine kinds of important diseases and insect pests, including powdery mildew, sharp eyespot and scab of wheat, rice blast, rice false smut, potato late blight, aphids, grain gall midge of wheat and corn borer, based on crop resistance, primary level of pests and short-term weather forecast.

本系统能够对小麦、玉米、水稻、马铃薯、高粱和谷子6种主要粮食作物的60余种病虫害进行实时监测、预警、诊断、提供植保知识，能够对年度间同期病情、虫情做出图形比较，可将抽象的预警数据转化成清晰简明的点图式电子地图，直观明了地显示病虫害发生点数及地域分布，可根据品种的抗病虫性、病虫害发生基数和未来天气预报等信息对小麦白粉病、赤霉病、纹枯病、稻瘟病、稻曲病、马铃薯晚疫病、麦蚜、小麦吸浆虫和玉米螟9种重要病虫害做出短期防治决策，系统的运行有助于提高人们对主要粮食作物病虫害管理的科学水平。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
