No design method available for direct application at home and abroad for the non - waveshape expansion joint of this regulating valve.
该调节阀采用的膨胀节是非波形的,国内外没有可直接使用的设计方法。
The testing current waveshape have been spectrally analysed, thus providing the theoretic basis for the verification of these items by using software that works as a part of the testing devices.
The AE technique could be used to monitor the lubricating condition in the course of the metal plastic deformation by the real time waveshape or mean value of the AE parameters.
采用声发射技术,基于实时波形和声发射信号参数的平均值都能监测金属塑性成型时的润滑状态。
In this paper, the time constant of theoretical waveshape and the parameters of discharge circuit were calculated by computer according to the parameters of virtual waveshape of lightning impulse.
