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。

The result shows that the mixed boundary condition can greatly reduce the calculation area without affecting accuracy of the solution.It is followed by the higher accuracy of Dirichlet boundary condition which makes the boundary error greater when measured points is near the boundary, so we must take a sufficiently large border region.The homogeneous boundary condition has relatively large error, but the use of non-triangle poles devices makes apparent resistivity calculation error become small, because of elimination of the effect on potential difference for the infinite boundary. In inversion, in order to save computing time, homogeneous boundary conditions are often used to perform finite element forward calculation.

结果表明，混合边界条件精度最高，可大大缩小求解区域而不影响计算精度，其次是Dirichlet边界条件精度较高，但测点越靠边界误差会越大，必须取足够大的边界区域，齐次边界条件的误差比较大，但如果采用非二极装置，通过电位差计算得到的视电阻率，由于无穷远边界对电位差的影响基本消除，视电阻率计算误差与混合边界条件下的接近，在反演中，为了节省计算时间，经常使用齐次边界条件进行有限元正演。

Boundary：边界

由于小说中城市景观的再现是通过小说中叙事者视角的结果,因此,本章所处理的不单是"看到什么具体景观"的问题,更是"谁看到这些景观"的问题,并利用"边界"(boundary)的观念分析城市景观的形成.

Boundary：界限

完整性原则关系到报告内容的三个方面,即范围(Scope)、界限(Boundary)和时间跨度(Time). 报告内容的"范围"指报告中所涵盖的议题及其指标要能充分反映机构的行为对经济、环境和社会方面的影响,使利益相关方能够评估报告机构的绩效.

Boundary：边缘

现在我们来研究T0,T1,T2,T3的边缘(boundary)的性质:T1的边缘是由二端点组成, 的边缘是由三个顶点及三个线段组成, T3是由四个顶点和六个线段及四个三角面组成.

Boundary：界面

再从界面(boundary)的定义来说,也应有此认识才合适. 比如一种定义认为,界面是"两个以上系统在结构上相互联系、相互影响和相互作用并在测度上首先承担和发生的边缘地带区域"[11、12]. 这意味着:①界面可以是一个"地带区域";

Boundary：abbr. bdy; 边界
