说明：  计算列车平稳性,计算sperling指标参数，可以画出频率和时间的图像(caculate the sperling index of the train)

将激光器输出的时间序列转化成频谱序列，以更好的分析频谱特性(The time series of laser output is converted into frequency series to better analyze the spectrum characteristics.)

滚球游戏意智游戏 问题描述 有八个小洞，序号和分布位置如图。小球从A、B、C（即洞号0、1、2）三个位置之一滚下。如果洞的状态为0时，球向左滚；如果洞的状态为1时，球向右滚。凡是球滚过的洞，状态取反（既由1变0，由0变1）。 现用8位二进制数依次从左到右表示八个小洞的状态。 例： 图中的初始状态为 00000101 时，最多滚入3个球时有 从C洞滚入一小球状态为 ――――＞ 00101111 从B洞滚入一小球状态为 ――――＞ 01111011 从A洞滚入一小球状态为 ――――＞ -bowls game Italy-game description eight holes and serial number and distribution figure. Small ball from the A, B, C (hole No. 0,1,2), one of the fallen three locations. If the state of the hole 0:00 a.m., the ball rolling left; If the state of the hole 1:00, the ball rolling right. Whatever strain at the hole, from the anti-state (both from a variable 0, 0 Variable 1). Now with eight followed by the binary number eight hole, said whatever the state.
