红外遥控器实现电机开关 开或关蜂鸣器都要响一下 电机可定时 类似于闹钟 只不过是时间到电机就停或开 定时开始或取消也是红外遥控器按键实现 红外遥控器有按键能实现增加和减少电机转速 电机接的是风扇(Infrared remote control to achieve motor switch on or off buzzer to ring Motor timing is similar to the alarm clock, but it is only time to the motor stop or start the timing or cancel the infrared remote control button Infrared remote control has keys to increase and reduce the motor speed motor connected to the fan)

 A function to raytrace through a sound speed profile to a given time. Raytrace will trace the path sound will travel through a medium with an  isotropic horizontal sound speed profile and a vertical sound speed  profile given by (zz,cc) from a point (xo,zo) and departing at an angle  theta0 for a time of tt seconds. The path is returned in vectors x and z.  The actual time of travel is returned in t, which may be slightly greater  that tt. The sound speed profile should include a measurement at the  surface (zz = 0). If it does not, the profile will be extended to the  surface by replicating the first measurement there.  In addition to the above, raytrace() handles caustics (when rays bend  through horizontal) and reflections off the surface (z=0) and bottom  which is taken to be at the maximum depth measurement in the soun
