For an incident laser beam with circular shape, a large filling factor can be realized and light energy can be sufficiently used. 对输入圆形光束有较大的填充因子，充分利用了光能。
The scaling factor specified is not a valid positive integer. 指定的定标因数不是一个有效的正整数。
The number of items in the polar array determines the scale factor increment. 圆形阵列的项目数量取决于缩放因数的增量。
