time derivative meaning in English
按时间的导数
时间导数
时域微分
Examples
- Nonholonomic constraint is the constraint that contains time derivatives of the generalized coordinates of the system and is not integrable
非完整约束是指含有系统广义坐标导数且不可积的约束。 - Nonholonomic constraint means that the constraint equation contains the time derivative of the systematic generalized coordinates , which are not integrable
非完整约束是指约束中含有广义坐标的导数,且这些导数不全部可积。 - Seek the b ( t ) fieldwork curve and the time derivative curve dbz ( t ) / dt from the voltage decrease data generalized from field current that eliminating noise treated by wavelet ; 3
由经过小波消噪处理过的野外归一化的电压衰减数据求出b _ z ( t )实测曲线和它的时间导数曲线( - Then in section 2 we discuss the elliptic problem which has time derivative on the boundary condition and obtain the corresponding regularity estimate which is quoted in chapter 3
第二节讨论边界条件含有时间方向上导数的椭圆问题，并且得到相关的正则性估计，其结果在第三章中被引用。
