英语翻译
1.In cases where the Pressure Ratio is not a ‘U’ shaped curve,the charge will be taken as the centre of the plateau of the discharge pressure.This ensures a very tolerant system,in that vent temperatures,and system pressures are tolerant to charge level across this range.Performance is not significantly improved for an increase in charge.There is also sufficient margin for tolerance to leakage.
