经过激波，气体的压强、密度、温度都会突然升高，流速则突然下降-After the shock, the gas pressure, density, temperature will rise suddenly, a sudden drop in flow velocity

实现换热站全自动控制 根据供水压力调节流速 流量 无人值守标准(Realize automatic control of heat exchanger station, adjust flow rate and unattended standard according to water supply pressure.)
