内角

In fact, a triangle formed for example, by the northern halves of two meridians and the section of the equator between them, will have two right angles at its base and an arbitrary angle at the top-a sum clearly greater than two right angles.

实际上，比如说，一个由北半球的两条子午线和它们之间的部分赤道组合成的三角形，将有两个直角作为底角，还有一个为任意角度的顶角-很显然它的内角之和比两个直角和要大。

Carried out generalized Mises yield criterion , yield curve on the n flat face was circle curve, and different elected parameters correspond to external angular point circumcircle、 internal angular point circumcircle and incircle of Mohr-Coulomb unequiangular hexagon. According to unequiangular hexagon, circle yield curve which had the same area as hexagon can be found, and corresponding yield criterionwas equilateral circle yield curve.

The choice for material of iron core, all the structure design and the method of collimation for the magnet were also described. Simulation results of Opera show that when the length of the core is 220 mm, the effective magnetic length is about 302 mm and the maximal magnetic density is around 0.215 T at four interior angles. Corresponding field uniformity is within 0.8% in the area of 133 mm×200 mm.

A fast algorithm for simple polygon triangulation is presented. Its thought is based on the dynamic judgment of interior angle. If the angle of point is smaller than 180 degree and includes no other points, then the point is connected into triangle. The data structure that enhances the efficiency of the algorithm is designed.
