脉冲

• A clock signal with 1 million pulses per second is referred to as a 1 megahertz .
  每秒钟有一百万个脉冲及时钟信号，也称兆赫（）时钟信号。
• The object of the filtering is to enhance the direct pulse from the shot and to attenuate the ghost .
  滤波的目的，是改善来自炮点的直达脉冲并压制伴随波。
• This particular half-sine pulse is only a very approximate model for the actual state of affairs .
  这个特定的半正弦脉冲对实际情况来说只是一个非常近似的模型。
• It uses binary counters for the conversion of the multiplicand from parallel to pulse-train form .
  它采用二进制计数器以把被乘数由并行形式转换成脉冲序列形式。
• After purging, oxygen pulses are injected until the detection system no longer indicates oxygen adsorption .
  脱氧后，注射氧脉冲直到测检系统表明不再有氧吸附为止。
• The dynamic sif variation was found to lag behind the stress-pulse impingement by several microseconds .
  人们发现，动态应力强度因子的变化滞后于应力脉冲冲击几微秒。
• Any process that will compensate for such distortions of the initial pulse should improve reflection quality .
  任何补偿这类初始脉冲畸变的处理，都能改善反射波的质量。
• Impulsive loads for structural tests have been generated by explosive cartridges or by small rockets .
  人们曾用过弹药筒的爆炸或用小型火箭来产生结构试验所需的脉冲荷载。
