正弦定律

Saw him this lecture, that we finally know the laws of spherical trigonometry sine, sina / sinA equal to what the final (the sine law of this plane is equal to the circumcircle diameter).

看了他这个讲义，才终于知道球面三角的正弦定律中，sina/sinA最终等于什么（平面的正弦定律这个等于外接圆直径）。

Determination of the horizontal angle of the triangle vertices and, based on the starting side length, azimuth, the starting point coordinates using the sine law to inquire the location of the vertex plane triangulation measurement method is called, the control points, known as the triangle point, this control network known as triangulation.

测定各三角形顶点的水平角，并根据起始边长、方位角、起始点坐标利用正弦定律来推求各顶点平面位置的测量方法称为三角测量，这种控制点称为三角点，此控制网称为三角网。

Because of being shear forming process, the relationship between the thickness ofthe deformed region, the thickness (t0) of the raw sheet, and the angleαbetween sheetmetal forming surface and vertical direction z conforms to the sine law, i.e.,t = t0 sinα.

由于金属板料数控渐进成形工艺的变形是剪切变形，故其板料变形区厚度 t 、板料初始厚度 t0及半锥角α等三者的关系符合正弦定律，即 t = t0 sinα。

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。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
