基本解釋[能源科學技術]二階時間導數(shù)英漢例句雙語例句This method measures the second derivative of the load current in real time to judge if there is a sudden change in the load current.實時檢測負載電流的二階導數(shù)，判斷負載電流是否發(fā)生突變。發(fā)生突變則采用預測控制程序模塊進行補償電流控制。And this, you will recognize is the first derivative of velocity versus time which is also the second derivative of position versus time.這點想必諸位已經(jīng)了然于胸,它就是速度對,時間的一階導數(shù),也是位置對,時間的二階導。Moreover, due to the dynamic equations of LPMs with second-order derivative terms in time, the resulting structure-foundation-soil system can be solved by an explicit time-integration method.此外，由于模型的動力方程具有二階時間導數(shù)項，因而應用本文模型的結構–基礎–土系統(tǒng)可以采用顯式時間積分求解。second time derivative更多例句詞組短語短語second -time derivative 二次導數(shù)second time derivative更多詞組專業(yè)釋義能源科學技術二階時間導數(shù)
