查询词典 evolutionary

To overcome the difficulties and the draw backs in modeling dynamic systems by traditional methods, a hybrid evolutionary modeling algorithm was proposed to model the Dynamic system with a system of ordinary differential equations whose main idea was to embed string coded idea and evolution algorithm optimize system.

针对传统方法解决动态系统微分方程建模问题所遇到的困难和存在的不足，设计将方程进行串结构编码并用进化方法进行演化建模的算法，以串形结构表示结构，用进化算法优化结构和参数，成功地实现了动态系统的常微分方程组建模过程的自动化。

Nonspecific cytotoxic cell is the evolutionary precursor of mammalian natural killer cell in teleostean fish, which was mainly separated from blood and lymphoid organ as the first barrier of defense to protect the animal against bacteria, virus and protozoa parasitism, it plays an important role in nonspecific immunity and also has a function of killing tumor cells in vitro.

自然杀伤细胞进化上的前体细胞在鱼类中被称作非特异性细胞毒性细胞，主要来源于血液和淋巴器官，是防御细菌、病毒、寄生性原生动物等入侵的第一道防线，在非特异性免疫中起重要作用，还具有体外杀伤肿瘤细胞的功能。
