在此基础上选取孔隙度、渗透率、流动层带指标等参数进行聚类分析，划分流动单元并建立流动单元判别指标体系。

Then this paper selects porosity, permeability, flow zone index and other parameters to carry on cluster analysis, divide flow units and establish identification index system of flow units.

此软件能根据一定的技术指标要求(如带宽、带外衰减等)，优化出双工器最佳参数。

According to the designing demands, such as bandwidth, stop-band attenuation, the optimization software can optimize the diplexers.

最后的值必须是一个小于该序列长度的非负整数，然后该序列就被请求将被赋对象赋值给它带那个指标的项。

The resulting value must be a nonnegative integer less than the sequence's length, and the sequence is asked to assign the assigned object to its item with that index.
