Moreover, by introducing memory function and vaccine inoculation mechanism of immune system, at the same time, DECA can converge to the optimal solution rapidly and stably.

通过改进的遗传策略来优化染色体长度，实现对聚类个数进行全局寻优，利用FCM算法加快聚类中心参数的收敛；并引入免疫系统的记忆功能和疫苗接种机理，使算法能快速稳定地收敛到最优解。

The codingoperator expresses the genes with N-decimal system floating numbers, and then the genes are divided into integer part and decimal part. The two parts are encoded into chromosomes respectively. The corresponding selection, crossover and mutation operators are designed with the theory of symbol encoding and the properties of N-decimal system floating numbers.

该编码算子首先将每个基因值用N进制的浮点数表示，然后将其分为整数部分和小数部分，分别重新编码组成染色体；相应的选择、交叉、变异算子采用符号编码的思想，充分利用N进制浮点数的特点进行设计。

This paper deals with the decimal (floating-point) representation, and constructs the simplex crossover operation combining with simplex methods of the non-linear optimization.

传统遗传算法用二进制位串表示群体中的染色体，当应用于参数优化问题时，这种表示法在求解精度等方面有一定的限制。

There were detestably close synapses between homologous chromosomes during thellateprophase and early metaphase in mitosis of somatic cells.

发现在其有丝分裂的晚前期、中期阶段，咯对同源染色体都在进行联会。

Truncation mutations in the adenomatous polyposis coli protein are responsible for familial and sporadic colonic tumours. Except for its function as a role in regulating b-catenin, recent studies show that APC has additional roles in cytoskeletal regulation. It binds to microactin and microtubules directly and indirectly. Furthermore, APC plays an important role in mediating the detraction of chromosome.

编码APC蛋白(adenomatous polyposis coli， APC)基因的缺失突变会导致家族性和散发性的结肠癌，APC蛋白除了能直接参与Wnt信号途径调节b-catenin的浓度之外，最近的研究表明APC蛋白能够与细胞骨架的主要成分微管和微丝直接或间接结合，通过调节微管的解聚和聚合，间接调节染色体的分离，作为潜在的细胞骨架调节分子将细胞骨架与重要的细胞信号转导通路紧密联系在一起。

He told me it was taken on Mount Diablo.

他告诉我这是对摩X染色体。

Diakinesis bivalents end of some of the homologous chromosomes together only at the end.

终变期末有些二价体的同源染色体只在末端连在一起。
