structure conversion ratio的意思|示意

For integer ratio conversion, the filters would be time-invariant, but for fractional ratio conversion, the filters would be time-variant whose structure is more complex.

实现整数倍采样率转换可以采用时不变滤波器，然而实现分数倍采样率转换一般需要采用较复杂的时变滤波器。

It has deduced the mathematical function of the sediment void ratio on the basis of stress and structure analysis, and then the mass and volume conversion of deep bed filtration sediment is given.
