The pent-up demand is starting to filter through, though it is more a trickle than a flood.

潜在的需求正在显露端倪，尽管他们比较洪水而言更像水滴。

In the design of filter, especially for the real time signal processing, the demand on the filter performance is not as high as that on the filter velocity.

在滤波器设计中，特别是实时信号处理场合，有时对滤波器的性能要求并不高，但对处理速度要求高。

Theoretic analysis and operation results confirm that the filter can resolve the demand of harmonic restraint and reactive power compensation effectively, and has good engineering application effect.

理论分析和现场运行情况表明，该有源滤波器能有效解决实际工况下对电网谐波抑制和无功补偿的需求，具有很好的工程应用效果。

The post on the official Google blog announcing the new extension, written by search czar Matt Cutts, would seem to give the lie to a claim by Demand Media CEO Richard Rosenblatt that his company is not among the spam purveyors that Google is trying to filter out.
