这个复杂运算过程的关键在于，这种乘除法混合物生成了一个纯粹的无因次数。

The point of this convoluted procedure is that this combination of multiplication and division produces a pure, dimensionless number.

假设，你找到。,无因次数，比如说找到-0。,这是n，1的解。,是1，ns是1，na，is，one，and，for，ns，is，one。,你将会看到。

Suppose you will find for this... for this dimensionless number, 0175 suppose you find minus 0.0175, which is the solution for n one... na So you'll see that.

采用无因次分析法得到了预测系统稳定的经验关系式，并得到了判断系统稳定性的界限图。

By means of dimensionless analysis an experimental correlation for predicting stability of system is obtained and stability threshold diagrams have been found.
