累计次数

该研究某些数据显示累计呼叫次数升高可轻微增加脑肿瘤风险，但是结果同样并不可信。

Other results showed high cumulative call time may slightly raise the risk , but again the finding was not reliable .

化学药品如东莨菪碱、亚硝酸钠、45%乙醇和戊巴比妥钠均引起小鼠学习记忆功能障碍，主要表现为在跳台作业中潜伏期短，累计错误次数增多；

The chemical drugs such as scopolamine , sodium nitrite , and 45 % ethanol , and sodium pentobarbital induced learning and memory dysfunction .

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 .

结果表明：PCC-PMCC复合式路面可承受的累计轴载作用次数比普通水泥混凝土路面提高了55%以上，性价比增大幅度可以达到12%以上；

The results show that the effect numbers of cumulative axle loading borne by PCC-PMCC composite pavement have improved 55 % than common concrete pavement and the performance-price ratio elevates above 12 % .
