现在，物质不灭宣告和能量守恒守律已经被千百万人所掌握。

In this paper, we constructed the new conservative schemes of regularized long wave equation according to the physical laws of this equation.

在本文中，我们基于RLW方程本身具有的物理律，构造RLW方程的新的守恒型差分格式。

Using DRG,we solved the KPZequation satisfy conservation law and long-range spatial and long-timecorrelation,the roughen and dynamic exponent was found,the roughentransition was also discussed.

本文利用动力重整化群方法研究了具有长程空间相关和长程时间、空间相关条件下的满足守恒律的生长方程，得到了粗化和动力学标度指数，并讨论了长程时空相关对生长表面粗化的影响[36，34]。

In this paper, a finite element method for linear scalar conservation laws is analyzed.

研究了一维线性标量守恒律初边值问题的弱解，分析了有限元方法的收敛性。

In chapter 3, a family of symplectic schemes are constructed for the KGS equations, and their conservation laws and convergence ratio are analyzed.

第三章构造了KGS方程组的一族辛格式，分析了此族格式的守恒律和收敛速度。

The "divide and conquer" strategy is used to improve the key steps of the undetermined coefficient algorithm for constructing polynomial conservation laws of nonlinear DDEs, so the calculation complexity problem caused by the dramatic increase of redundancy is solved. Furthermore, Wu\'s elimination method is applied to solve the obtained nonlinear algebraic equations thus to get a more efficient algebraic algorithm.

本文从微分方程的标度变换出发，利用"分治"策略改进了构造非线性DDE守恒律待定系数算法中的关键步骤，有效解决了因冗余项急剧增加引起的中间计算过程膨胀问题，并将吴消元法应用到非线性代数方程组的求解上，从而给出了一个更高效的代数算法。

In order to understand the weak solutions like piece-wise smooth solution, we must investigate the structures and properties of global smooth solution.

一般情况下，要研究清楚分块光滑解等常见的弱解，我们必须研究光滑解尤其是全局光滑解的结构和性质，这是研究高维守恒律方程方程全局解的基础。但用以往的处理方法一般来说是很困难的。

We show that the multisymplectic conservational law of Bridges' and MPS' areequivalent.

我们还证明了两种意义下的多辛守恒律的等价性。

And through these estimates , we prove the local well-posedness of modified Korteweg-de Vries equation in a quarter plane.

在第三章中我们证明了&几乎守恒律&，从而证明了非线性Davey-Stewartson方程在空间H~s(R~2)(这里s＞4/7)整体适定性。
