细胞学说

He thus confirmed the cell theory of Schleiden and extended it to animals.

因此他更为肯定施莱登的细胞学说并将之应用于动物个体。

Cell theory The theory that all organisms are composed of CELLS and cell products and that growth and development results from the division and differentiation of cells.

细胞学说：所有的生物体都是由细胞及细胞产物构成的。细胞的分裂和分化导致细胞的生长和发育。

The development of cell theory in the eighteenth and nineteenth centuries caused biological research to blossom and bear fruit at all levels.

细胞学说在十八和十九世纪的发展，促进生物学各个方面的研究开花结果。

After years studying the microscropic structure of plants, he proposed his cell theory Contributions to Phytogenesis(1838), in which he stated that the various plant structures are all composed of individual cells.

经过多年对植物显微结构的研究，他在1838年发表了的《植物发生论》中提出了细胞学说，指出细胞是构成植物体各种结构的基本单位。

In the mid-19th century the humoral theories of infection were replaced first by cell-based theories and then by the bacteriologic theories of Robert Koch and Louis Pasteur.

在19世纪中叶，感染的体液免疫说开始由细胞为基础的学说以及后来科赫与巴斯德的细菌学说所取代。

And the law of conservation of energy, metabolism, photoelectric transformation, electromagnetic transformation, photosynthesis, general and specific theories of relativity, monomolecular, monatomic theory, life science, cell theory, gene theory, anthropic principle, uncertainty principle, and the theory of "cosmic explosion" are all concrete evidences of natural sciences for the Great Balance Theory.

而以往能量守恒定理、新陈代谢、光电转换、电磁转换、光合作用，广义、狭义相对论、单分子、单原子理论、生命科学、细胞学说、基因学说、人择原理、测不准原理及"宇宙大爆炸"等理论，都为大平衡提供了自然科学的实证依据。

He number of TCR V(Vα equal s to 100 and Bβ equals to 30 ) is less than the one of lg Vh (Vh equals to 300),for TCR V is subject to negative selection of major histocompatibility complex according to the neutral theory We discussed that is somatic mutation or DNA rea rrangement the main force in producing antibody diversity and are there pseudoge nes in TCR V or not.

CR V的数目(V α为100，Vβ为30)远少于Ig VH(数目为300)，原因是前者受到主要组织相容性复合体的制约，即受到负选择，这与中性学说观点相一致。文章还讨论了体细胞突变和DNA重排对两类抗体多样性产生上的作用，并探讨了Ig VH和TCR V的假基因问题。关键词分子进化，协同进化，免疫球蛋白，T细胞受体，中性学说

This problem has been numerous points of scientist research,currently is to let a hundred flowers blossom,profusion of different opinions,appeared several ten kinds of theories and theories,such as:lnherit the gene theory,immunity,free free radicals theory,endocrine system theory,the body cell mutation theory etc,these theories and theories are all to reflected to result in the factor of the decrepitude from an on the side.

人类衰老一直是众多科学家研究的重点，衰老的理论和学说百花齐放，众说纷纭，如：遗传基因学说、免疫学说、自由基学说，内分泌系统学说、人体细胞突变学说等，这些学说和理论都从一个侧面反映了造成衰老的因素。
