Second moment of area of tranformed section 换算截面惯性矩34
Second moment of area 截面惯性矩
It has been shown that the m2 values of semiconductor lasers , which are defined by the second moments , are always larger than unity 理论和实验结果表明,在二阶矩的定义下,半导体激光光束的质量因子总是大于1的。
In the last days of the second moment a great war is to be concluded with judgment and a global conflagration lasting 1 , 468 years 在第二片刻的最后日子,一场世界大战最后是随着审判而来,一场全球的大火灾持续了1 , 468年。
( 4 ) the difference of the constraint conditions makes the second moment in prestressed frames less than that in the prestressed beams ( 4 )约束条件的不同使单层两跨预应力混凝土框架梁中的次弯矩要远小于两跨的预应力连续梁。
The three - dimensional ocean mode , pom , which contains an imbedded second moment turbulence closure sub - model could simulate well the tides in the study region 湍封闭的三维全流动力模式pom可以较理想地模拟渤黄东海的潮波。
Then the proportion of the modulation of moment taken by the second moment in the total modulation in prestressed frame is less than that in prestressed beam 同时,次弯矩调幅占总调幅的比重在框架中要远小于连续梁。因此,次弯矩协助调幅的作用在框架中也弱于在连续梁中。
Furthermore the computer program ism for analyzing structural reliability is developed by using advanced first order second moment method and important sampling monte - carlo method 分析了4种损伤:即疲劳、凹坑、腐蚀和海生物损伤,并推导出时变构件可靠性计算的有关公式。
