对边

For me...It's the last dance as the walls are crumbling around you...

对我来说，这就像是在一堵正在倒塌的墙边的最后舞蹈

According to the principle of the diameter of a circle corresponding to the right angle and the principle of short side for little angle in right triangle, projecting the initially-chosen point to the hyper-planes of the linear equation group in which every linear equation can be regarded as a hyper-plane and the projection points can be obtained. The initially-chosen point, and one arbitrary projection point, and the solution point are all on the surface of the relative hyper-geometry ball, therein-to, there is a projection point which is nearest to the solution point and it can be regarded as the next iterative initially-chosen point, so the solution problem of the linear equation group can be changed as an iterative problem of approaching the solution on the surface of a hyper-geometry ball.

根据直径对应的圆周角足直角以及直角三角形中短边对小角的原理进一步知道，当将初始点向线性方程组中各个方程所代表的超平面上投影得到投影点时，初始点和其任何一个投影点及方程组的解点都将位于一个相应的超球面上，其中必定存在一个投影点离问题解点的距离最短，即把该点作为下一次迭代的初始点，从而可将线性方程组求解的问题变成球面上逼近解点的迭代问题。

攻占殿边府的成功很大程度上要归功于大量补给与装备的成功运输，还有同样成功的对法国地面攻击部队的"空中阻隔"。

The difference schema of the initial boundary value problem was converted to the step-by-step form,which was similar to the difference schema of the initial value problem.It is concluded that the difference schema satisfying the Von Neumann condition is a stable schema,and that,under the consistency condition,such stable schema is convergent.Moreover,with error estimate expression for the difference approximation to the classical solution,the linearity condition is unnecessary.

引入反投影算子将发展方程初边值问题的差分格式转化为与初值问题差分格式类似的逐步推进的形式，从而得出：满足Von Neumann条件的差分格式是稳定的格式；在相容条件下，差分格式若稳定(或满足VonNeumann条件)则格式收敛，且对古典解的差分逼近有误差估计式，不再需要线性的条件。

Dupont[15]使用标准能量方法给出了一类线性双曲方程Galerkin解的L2误差估计，对于Dirichlet型边值问题，Baker[1]对其结果作了改进，用的是一种可谓"非标准的能量不等式"方法。

Trajectory energy dissipator, as one of main dissipator ways of hydropowerstation that locate in deep valleys and with high water head and large dischargecapacity, is much effective. But discharge atomization causing from trajectory energydissipator is often serious and has badly impact on downstream rock slope stability,which is arousing attention of some domestic and oversea scholars.
