约瑟夫环：编号为1,2,3,…,n的n个人按顺时针方向围坐一圈，每人持有一个密码（正整数）。一开始任选一个正整数作为报数的上限值m，从第一个人开始按顺时针方向自1开始顺序报数,报到m时停止。报m的人出列，将他的密码作为新的m值，从他在顺时针方向上的下一人开始重新从1报数，如此下去，直到所有人全部出列为止。编程打印出列顺序。-Josephus : No. 1, 2, 3, ..., n n clockwise direction by individuals sitting around a circle, each holding a password (positive integers). An optional started as a positive integer reported limits on the number of m, from the first individuals to embark on the clockwise direction since the beginning of a sequence number off, the report m stop. M reported out of the list of his password as a new value m, from a clockwise direction in the next one started from a newspaper a few, like that, until the total of all listed so far. Programming print out the order.

物体不透明的情况下，物体表面的颜色仅有其反射光决定。反射光由环境反射、漫发射及镜面反射着三种类型的分量组成。其中环境反射式入射光均匀地从周围环境入射到物体表面后等量地向各个方向反射的光。冯氏模型假设物体某点上的反射光的强度时这三种反射光的叠加。
