你如何设计出一个线路，可以使雨刮在完成一个周期后停下来，一段时间后再运行一次？
How do you design a circuit where the wiper comes to a stop at the base of the windshield and then goes into its cycle again?
就像是在夏季经历了一段令人头昏脑胀的炙热天气之后，突然下了一阵季雨。
IT CAME like monsoon rain, after a head-aching spell of summer heat.
此外，由于从热变冷需要一段时间，因此仅让雨刮短时运行也非常困难。
Also, getting the wiper to dwell for short periods was difficult, because of the time it took for the switch to heat and cool.
