当脉冲作用点在受损单元的起始位置时，脉冲作用点横向速度波首波波幅变化越大，损伤越大，脉冲作用点横向速度波的第一个波谷到达时间越晚，损伤单元越长。
The greater the amplitude change of head wave of transverse velocity is, the severer the damage is, the later the arriving time of the first wave hollow and the longer the damaged element will be.
模拟结果表明，对于这种脉冲激光，光化学中双光子反应主要是由起始时未被充分散射和吸收的脉冲所驱动，而单光子反应是由经散射后的浸射光所驱动。
For the impulse, the two-photon reactions were dominated by the initial primary (unscattered and unabsorbed) pulse and the single—photon reactions were dominated by the scattered diffuse light.
初步结果表明，微破裂的集结和断层的破裂起始会出现超低频脉冲，并透射到空气中形成次声波。
The primary results show that the ultra low-frequency pulses may produce in the process of nucleation of micro-cracks and faults, and transmit to the air as infrasonic sound.
除此之外，也不必事先固定传输速率，因为接收器可透过起始位元内两脉冲之间的距离，测量出传输速率。
In addition, the spacing between the pulses in the start bit allows the receiver to measure the transmission rate; the rate does not need to be fixed in advance.
