用三棱锥法计算空间角度

Using Pyramid Method to Calculate Space Angle

介绍了一种求解空间角度的简捷方法．即对空间角度可直接建立球心三面角构成球面三角形，并通过计算球面三角形的方法求解空间角度．这种方法对计算空间角度精确简捷，简称三棱锥法．

In this paper,a simple and direct method is introduced to calculate the space geometrical angle. A spherical center three surface angle can be directly built in accordance with the space angle, which makes up a spherical triangle, then the space angle can be calculated using the method of calculating the spherical triangle.This method can be simply called pyramid method.
