By using transducers of differential pressure to measure flux directly, the relation between current output and measured flux will be nonlinear.

采用差压变送器直接测量流量，输出电流与被测流量将是非线性关系。

For the end, an equation of mass flux of jet about time deduced by the differential element method was compared to CFD results, and the influence of design parameters was analyzed.

最后利用微元法得到了射流流量随时间变化的函数关系式，并和数值模拟值进行了对比，分析了各设计参数的影响。
