wpd造句

例句与造句

Based on wavelet packet decomposition （ wpd ） , entropy threshold method （ etm ） has been put forward to reject the discrete spectrum interference （ dsi ） in on - line pd monitoring
首次提出用于抑制局部放电在线监测中周期性窄带干扰的小波包变换熵阈值法（ etm ）。
With the frequency division of wpd , etm uses shannon entropy as the criterion of determining whether or not dsi exist in certain wpd tree nodes and interference are suppressed successfully . lots of simulation data , lab data and on - site data have indicated that etm works with good efficiency , without pre - knowing of dsi information , extracts the phase of pd pulses accurately and can calibrate quantity of single type discharge
大量的仿真数据、实验室实测数据以及现场实测数据处理结果表明，小波包变换熵阈值法抑制干扰能力强，无需事先确定干扰的分布，能够准确检测局部放电信号的相位信息，对于单一的放电类型，可以确定放电量的大小。
It's difficult to find wpd in a sentence. 用wpd造句挺难的
