The carrier gas is supplied to the instrument at constant pressure from a cylinder. 载气一般由压缩钢瓶供给，并要使载气压力恒定。
On the right hand side of the instrument panel, there is a display that indicates boost pressure, water temperature and fuel level. 在仪表板右边有一个指示增压压力水温和油位的显示器。
The system can get very high supercharging pressure when the speeds of the two stage turbochargers are rather low, which ensures the system's security and reliability. 两级增压器转速较低时能达到很高的增压压力，保证了系统的安全性与可靠性。
