Compared with the initial value problems of scalar conservation laws with smooth flux function, the global weak entropy solutions for the initial-boundary value problems of scalar conservation laws with weak discontinuous flux function include the following new interaction types: a rarefaction wave collides with the boundary and is absorbed compltetely or partially by the boundary; a rarefaction wave collides with the boundary and the boundary will reflect a contact or non-contact shock wave; a contact or non-contact shock wave collides with the boundary and is absorbed by the boundary; a contact or non-contact shock wave collides with the boundary and a new non-contact shock will rebound from the boundary simultaneously or later.

与具有光滑流函数的单个守恒律的初始值问题相比，具有弱间断流函数的单个守恒律初边值问题的整体弱熵解中包括下列新的相互作用类型：稀疏波碰到边界并被边界部分或全部吸收；稀疏波与边界相撞，边界反射出一个接触或非接触激波；接触或非接触激波碰到边界并被边界吸收；接触或非接触激波与边界相撞，边界同时或稍后反射出一个新的非接触激波。

In addition, total wheel/rail contact calculation with divided rail outline method are raised. Under the condition of considering the displacement, bouncing, yaw, roll of wheelsets and displacement, bouncing, roll of rails, minimum gap between rail and wheel were calculated by the trochoid method and divided rail outline method, we can easily judge totally real contact states of the wheel/rail such as normal one-point contact, nonnormal one-point contact, two-point contact and wheel complete lift. Wheel/rail normal forces in the two contact point are respectively calculated by nonlinear Hertz contact theory, and then, result of simulation more close to reality on actual track.

另外，提出了轨廓分区法全面计算轮轨接触状态法，在考虑轮对的横移、浮沉、摇头、侧滚和左右钢轨的横移、浮沉、侧滚的条件下，可全面地分别计算左右侧轨顶和轨侧区域与车轮的最小轮轨间隙量，以此来判断轮轨的真实接触状态：正常的一点接触、非正常的一点接触、两点接触和车轮完全悬浮，并根据非线性赫兹接触理论分别求得两接触点处的轮轨法向力，从而使仿真结果更接近于车辆在实际线路上的运行状态。

The gap element method is proposed in the paper for two kinds of problems, which include contact problem and gap joint problem. Elasticity contact problem falls into the category of unknown boundary value problems. It follows that the contact area and contact conditions or states can never be determined without special mathematical analysis, which is a very difficult work. The boundary conditions of the contact surfaces are deduced.

文中给出了间隙元法在空间可动部件接触问题中的应用，推导了其几何边界条件和力学边界条件，利用虚功原理推导了含间隙元弹性接触问题的有限元方程式，给出了其数值解法的迭代步骤，并指出了利用间隙单元进行分析的特点。
