A discontinuous method is proposed for arbitrary convex polyhedral finite elements in the context of elasticity.

对弹性力学问题,提出一种任意凸多面体间断有限单元法。

The intermediate value theorem for discontinuous function is studied,the problem of discontinuous points when the left and right limit exists is considered by ZHU Le-min.

研究了非连续函数的介值定理,受朱乐敏等考虑的具有左、右极限存在的跳跃间断点的非连续函数的介值性定理的启发,利用上、下极限把介值定理推广到具有一般间断点的非连续函数的情况。

In this paper,we generalize the intermediate value theorem from continuous to discontinuous.

本文将连续函数的介值定理推广到间断的情况,文中的思想方法在其他领域如数论中也是有用的。

A contact algorithm which describes the contact interaction between SPH particles by means of Riemann solution was used to calculate the discontinuity of the variables defining the one-dimension fluxes.

采用以黎曼解描述粒子间相互作用的接触算法,模拟一维情况下包含间断的流场。

In this paper it has been proven that for Cauchy problem of quasi-linear homogeneous partial differential equation its solution always has discontinuity, and the trace of discontinuity is just the envelope of characteristic lines.

本文证明对于拟线性齐次偏微分方程的Cauchy问题,其解总具有间断性,且发生间断的点的轨迹,恰巧就是特征线的包络,另外给出了一个特例,否定了这类解必定会出现多值性的定性论断,从而使构造广义解的理论面临困难。
