According to this method of multi-polar set dynamic balancing valve design concept is wrong.
而按照这一方法多极设置动态平衡阀设计概念是不对的。

RESULTS: The quasi-polar drive pattern was optimal in all aspects except the dynamic range. Polar and cross drive patterns and adjacent drive pattern followed in a descending order.
结果除动态范围外，准对向驱动模式均为最优，对向和交叉驱动模式次之，邻近模式最差。
