These genes play a central role in the developmental processes of the anterior-posterior axis of vertebrates by regulating the fetation,and define body pattern in the vertebrates.

这些基因调节胚胎发育，尤其在脊椎动物前-后轴(antero-posterior axis)的发育过程中起着重要作用，并指导脊椎动物的体型形成。

Because the vertebrates express anatomical characteristics consistently during the process of fetation, many researchers conjectured ancient vertebrates by the characteristics of the animals living nowadays and speculate the origin and the process of evolution.

由於所有的脊椎动物在其胚胎发育中都呈现连续的解剖学特徵，因此过去很多学者都根据现存脊椎动物的形态特徵和在其发育过程中的解剖学特徵假想原始脊椎动物，并推导其进化过程和起源。

A kidneylike organ, being either part of the most anterior pair of three pairs of organs in a vertebrate embryo, disappearing early in the embryonic development of higher vertebrates, but functioning as a kidney in some simple vertebrates, such as the lamprey.

前肾，原肾一肾状器官，是脊椎动物胚胎中三对器官最前面一对的一部分，在高级脊椎动物的早期发育时消失，但在一些初级脊椎动物中作为肾脏，如八目鳗

A kidneylike organ,being either part of the most anterior pair of three pairs of organs in a vertebrate embryo ,disappearing early in the embryo nic development of higher vertebrates,but functioning as a kidney in some simple vertebrates,such as the lamprey.

前肾，原肾一肾状器官，是脊椎动物胚胎中三对器官最前面一对的一部分，在高级脊椎动物的早期发育时消失，但在一些初级脊椎动物中作为肾脏，如八目鳗

An internal supporting skeleton,derived from the mesoderm,that is characteristic of vertebrates and certain in vertebrates .

骨骼体内支撑的骨骼，由中胚层而来的，是脊椎动物及某些无脊椎动物所特有的特性

Compared with the former study of interaction between varieties of vertebrates hemoglobin and human hemoglobin, human fetal hemoglobin, the results support the conclusion about the boundary of interaction between vertebrates hemoglobin and kinds of protein molecule in the electric field is the Reptilia animals and enrich the theory of hemoglobin molecular evolution.

同前面所进行的各种脊椎动物血红蛋白分别与人血红蛋白、胎儿血红蛋白相互作用的研究对照比较，进一步验证脊椎动物血红蛋白与各种蛋白分子在电场中的相互作用的分水岭可能位于爬行纲动物，丰富了血红蛋白分子进化理论。

Compared with the former study ofinteractionbetween varietiesof vertebrates hemoglobinand human hemoglobin, human fetal hemoglobin, the results support the conclusion about theboundary of interaction between vertebrates hemoglobin and kinds of protein molecule in the electric field is the Reptilia animals and enrich the theoryof hemoglobin molecular evolution.

同前面所进行的各种脊椎动物血红蛋白分别与人血红蛋白、胎儿血红蛋白相互作用的研究对照比较，进一步验证脊椎动物血红蛋白与各种蛋白分子在电场中的相互作用的分水岭可能位于爬行纲动物，丰富了血红蛋白分子进化理论。

However, some recent studies demonstrated that urochordate sea squirt is the sister group of vertebrates instead of cephalochordates.In order to further elucidate the relationship in cephalochordates,urochordates and vertebrates and therefore,it is very essential for carting through transcriptome-wide analysis of amphioxusand comparating with sea Urchin and sea squirt.In addition,it would also provide an important foundation for further annotating and assembling of the forthcomingly publicized amphioxus genome.

近来分子系统学的研究结果对文昌鱼的进化地位提出了挑战，因此本论文在文昌鱼基因组计划尚未完成之前，对文昌鱼EST序列的转录组比较分析以及EST数据库分析平台的建立，为更进一步地注释文昌鱼的基因功能、揭示其进化地位以及比较基因组学的研究都具有十分重要的理论与实践意义。

When the first edition of this work was published, I was so completely deceived, as were many others, by such expressions as "the continuous operation of creative power," that I included Professor Owen with other palaeontologists as being firmly convinced of the immutability of species; but it appears ("Anat. of Vertebrates," vol. iii. p. 796) that this was on my part a preposterous error.

当本书第一版刊行时，我和其他许多人士一样，完全被&创造力的连续作用&所蒙蔽，以致我把欧文教授同其他坚定相信物种不变的古生物学者们放在一起，但后来发现这是我的十分荒谬的误解（《脊椎动物的解剖》［Anat.of Vertebrates］，第三卷，796页）。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
