Calculating of rotating speed of rotating machinery and method of key phasor pulse processing 旋转机械转速计算及键相脉冲处理方法
Frame synchronization is a key part in Pulse Position Modulation. The performance of this part affects the whole performance of the PPM system. 帧同步是脉位调制中关键的一部分,其性能的好坏直接影响到整个系统的性能。
The second chapter from the text itself the analysis sets out, discussed the author in the text to use the processing time of the narrative strategy and method, get the unlock time narrative clues to find the key, the pulse of time. 第二章从文本内部分析出发,具体探讨作者在文本中运用到的处理时间的叙事策略和方法,拿到解开时间叙事线索的钥匙,寻找文章的时间脉搏。
During multi-pulse laser processing, another key parameter was pulse frequency, whose variation range was calculated as the function of the energy density of laser. 多脉冲激光辐照时,脉冲频率是另一关键参量,计算得到了不同能量密度的脉冲激光辐照时频率的选取范围。
It is found that angular dispersion can compensate group velocity mismatch, crystal length is no longer limited by group velocity walk-off length as common frequency doubling, then diffraction and dispersion effects play key roles in pulse width broadening of second harmonic. 分析发现角色散匹配技术可以补偿群速度失配,晶体长度不再像普通倍频那样受到群速度走离长度的限制,这时衍射效应和色散效应对谐波脉宽展宽起主导作用。
