冲击次数 meaning in Chinese
shock times
Examples
- The shorter the interval between the two pulses of the current wave , the fewer strikes the varistors can endure . at the same time , the dc ljima changes fast - slowly - fast alone with the experiment continuing . microstructual disorder , such as variations in the height of the electrostatic potential at grain boundaries and electrode protrusions into the zinc oxide varistors , causes substantial temperature rise in a microscopic region around the defect and is the source for failure
雷电的多重闪击对雷电过电压保护器件的影响更加严重，本文首次采用不同间歇时间双脉冲电流冲击对氧化锌电阻进行了多次试验，试验表明：氧化锌电阻在双脉冲电流冲击下更容易出现老化破坏现象，间歇时间越短，电阻能耐受的冲击次数越少；此外，直流u _ ( 1ma )值随冲击次数的增加具有快一慢一快的下降过程。 - Abstract : based on laboratory test results , a model for predicting the residual deformation of soft clay under impact loading is proposed in this paper , which fits well with other test results . this model , considering several factors which affect the residual deformation such as confining pressure , impact energy and the number of impacting , can be used for the deformation prediction in the treatment of saturated soft clay by the drainage consolidation method of combining static and dynamic loading
文摘:在试验基础上建议了一个预测冲击荷载作用下饱和软粘土残余变形的计算模式，该模式考虑了周围压力、冲击能大小、冲击次数和冲击遍数等几个因素.对计算模式的验证表明，预测值与实测值吻合较好.该模型可用于动静结合排水固结法处理软基时的变形计算 - Adding sic can decreases sintering temperature of al2o3 efficaciously , but also can make the al2o3 crystal growth as flake , strengthen the coalescent of the al2o3 crystals , and the residual sic during sintering can strengthen the al2o3 ceramics . because the reaction between sic and al2o3 begins from the surface of samples , there is a compact protecting field on the surface of the samples to restrain o2 enter into the samples , and leave more pore in them to decrease the thermal expansion coefficient and increase their the al2o3 ceramics " thermal shock resistanc e times
引入sic的样品在烧结过程中，首先在样品的表面产生sic与o _ 2及al _ 2o _ 3的反应，形成一层致密的保护层，阻碍o _ 2进入材料内部，在材料的内部留下较大的气孔率，可以降低其热膨胀系数，并使材料在受热过程中有一定的空间进行结构调整，能够显著的提高al _ 2o _ 3陶瓷材料的抗热冲击次数。
