G UILLAIN-BARRéSYNDROME(GBS)is an uncommon disorder,but one whose impact is far out of proportion to its incidence.Despite a usually good prognosis...
发生火灾时为了降低乘客伤亡事件的发生率,基于STC12C5A60S2单片机设计了一个车载玻璃破碎器。温度传感器选用DS18B20,烟雾传感器选用MQ-2。单片机输出的脉冲信号通过UNL2003进行功率放大,传送到步进电机28YJ-48。设计了使用1T单片机后传感器所需要的初始化及读写时序的程序。A ...
