The wash-out of the particle slope, in practice is how the particle stone to move under the breaking wave"s force. The main elements deciding the force are the wave factor, the slope angle and the particle size. Through analyzing the particle"s suffering process during each stage of waves breaking, it can be advanced that the wave force is biggest just at the wave incidence to the slope.

波浪对散体边坡的冲刷，实际上是颗粒在波浪作用下的受力起动问题，力的大小主要由波要素、斜坡倾角和颗粒粒径决定，且通过对破波各阶段颗粒的受力分析，可知颗粒在破波瞬间受到的作用力最大。

The experimental results show that when TCAR is about 700 ℃ XN for limestone is maximum, and the optimum TCAR for dolomite is about 650℃. Although XN for limestone is much higher than dolomite, the difference of their YN is little when TCAR is in 650~700 ℃. And if TCAL is beyond 1050 ℃ XN for limestone decays sharply, but it is negligible to dolomite. XN for dolomite is far higher than limestone in the high TCAL. XN for limestone decreases with the particle size increasing, and there is an optimum particle size range with particle size increasing which XN for dolomite reaches maximum in. The particle size plays a more important role in limestone carbonation process than dolomite.

结果表明：TCAR为700℃时石灰石的XN最高，白云石则在650℃时XN最高，在650～700℃时白云石的XN远高于石灰石，但它们的YN相差不大；当TCAL超过1050℃时石灰石的XN急剧衰减，而白云石的XN则衰减程度不大，在高温煅烧时白云石的YN比石灰石更高；随粒径的增大，石灰石的XN逐渐减小，而白云石则存在最佳的粒径分布使XN最大，粒径的变化对石灰石的XN影响更大。

The effect, acting together with the other one that the lower emission barrier facilitates the particle emission, leads to a different way to emit proton and α particle.

从这个角度，笔者研究了引入曲率能和压缩能影响断前粒子发射的效应，与发射位垒降低增强断前粒子发射的效应相作用，使断前质子和断前α粒子在基态到鞍点间出现了不同的发射规律。

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。
