The open loop time constant of the main generator influence the overshooting evidently. The important factor is the rising speed of the output DC voltage.
主发电机的开环时间常数会对建压过冲产生影响，而输出直流电压的上升速度也是一个重要因素。
This system bases on semiconductor modulated laser, which replaces blackbody radiation source, and uses the technology of VC call MATLAB realizing graphic model output and time constant calculate.
它用可调制半导体激光器替代黑体辐射源，通过VC调用MATLAB来实现图形的输出和时间常数的计算。
At the same time, constant engine speed stabilizes output displacement of hydraulic pump and then stabilizes travel speed and vibratory frequency in turn, so that compaction quality is increased.
同时，发动机转速的恒定也使液压泵输出排量稳定，进而保证了行走速度和振动频率的稳定，提高了压实质量。
