When the moving-star arrived to the side of another star, both two stars(star-A and star-B) began to move in a circle orbit that the two stars are constantly at the two terminals of a diameter of the circle.

Microscope and image analysis technique are adopted in 《JB/T 7990-1998》. The "grain size" tested by microscope is expressed by the "largest breadth" of the grain image. When the grain size is tested by image analysis instrument, the grain size is expressed by the diameter of a circle whose area equals the grain image's.

JB/T7990-1998》规定用图像分析仪或显微镜测量粒度，显微镜法测量的"粒度"是以颗粒投影的"最大宽度"来表征的，而用图像分析仪测量的"粒度"指的是"等面积圆直径"，即，用与颗粒投影面积相等的圆的直径表征颗粒粒度。

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。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
