In this paper, a finite element method for linear scalar conservation laws is analyzed. 摘要研究了一維線性標量守恆律初邊值問題的弱解，分析了有限元方法的收斂性。
In order for energy to be conserved, the final total kinetic energy must be greater than the initial by this amount. 要符合能量守恆原理，末總動能必須比初動能大這麼多。
Namely, because of medium nonlinearity, the energy of different modes of seismic waves is reassigned and displayed in records but fits the energy conservation law. 在遵守能量守恆原理的前提下，介質的非線性會引發地震波場中各波型間能量的再分配。
