At the same time some problems, such as negative correlation, selectionof correlation coefficient, are discussed also.
同时，也对指标间的负相关、相关系数的选择等问题进行了探讨。
2
Through technical analysis and calculation, the critical coefficient and optimal load rate of transformer are determined for the reasonable selection of transformer capacity.
通过技术分析和计算，确定变压器临界系数以及变压器的最佳负载率，合理选择变压器的容量。
3
The takeover time coefficient is given, so the influence of different selection operators and transformation of fitness function can be measured quantitatively.
