小数部分

The symcenter of conoscopic interference pattern is corresponding to vertical incident light and crystal birefractive index is proportional to interference order m. Decimal fraction of interference order m is calculated by the placement of central dark fringe and integer part is ascertained by self-consistent method.

干涉图的对称中心对应于正入射光线，双折射率正比于此点的干涉级m，m的小数部分主要由中央暗条纹的位置决定，m的整数部分由自洽的办法求出。

The decimals with one or more number repeating at the decimal part are called the circulating decimals.

重点句子：*1、小数部分有一个或几个数字依次不断重复出现，这样的小数就是循环小数。

In the early stage of the genetic algorithms, the three genetic mechanisms are used both in integer part and decimal part, so that the genetic algorithms have stronger global search ability, keep the population diversity efficiently and avoid falling into local extremum. In the later stage of the genetic algorithms, the three genetic operators are used in decimal part, so the genetic algorithms have stronger local search ability and fast convergence ability.

在遗传算法开始阶段，该编码算子进行整数部分和小数部分的遗传操作，使得遗传算法在早期具有很强的全局搜索能力，避免陷人局部极值；在后期进行小数部分的遗传操作，使得遗传在后期具有很强的局部搜索能力，能够很快地搜索到全局极值。
