它可以在重复频率从0.5Hz,1Hz,直到20Hz的条件下连续工作,所达累计充放电次数已分别为10~7次,5×10~4次和10~8次。这个新的脉冲发生器工作稳定、可靠。
The repetition rate is from 0.5 Hz , 1 Hz up to 20 Hz and accumulative total charge-discharge times are 107 , 5 × 104 and 10 ~ 8 , respectively .

从重载交通的标准轴载换算和累计当量作用次数入手,得出超载是水泥混凝土路面结构早期破坏的重要原因之一。
By means of conversion to standard axle load and calculation of accumulated applications of the equivalent axle load , it could be concluded that overloading is one of the most important reasons for the premature failure of cement concrete pavement structures .
