Finally, based on the total variational equation, the finite element method of these problems is also discussed.
最后讨论了利用全变分方程建立有限元的方法。
Dynamic traffic assignment is to assignment the time to time variational traffic into different routes to reduce traveler's cost or system's total cost.
所谓的动态交通分配，就是将时变的交通出行需求量合理分配到不同的路径上，以降低个人的出行费用或系统总费用。
The variation trends of precipitation and total amount of water resources are identical, but the former's variational rate is smaller than the latter's.
水资源总量的变化规律和降水变化规律一致，但前者的变化率明显大于后者。
