不受背压影响，背压率可以达到进口压力的80%左右。
Carrying pressing influences, about 80% that can reach the inlet pressure while carrying the pressing rate.
过冷度小，背压率高。在加热设备和凝结水回收系统工程上使用，更显其优越性能。
Low undercooling degree, the rate high back press. On the heating equipments with condensed water and the recovery system engineering, even show its ascendant function.
背压率大于80%，能排不凝结气体，膜盒坚固，使用寿命长，维修方便，使用范围很广。
Back pressure higher than 80%, to row non-condensing gas, diaphragm solid, long life, easy maintenance, using a wide range.
背压对贯穿距离、喷雾锥角、喷雾轴心速度和浓度衰减率的影响均大于启喷压力。
It shows that the effects of back pressure on penetration, spray cone Angle, and decline rate of centerline velocity and concentration of the spray are greater than that of fuel injection pressure.
目前双背压汽轮机是按单背压汽轮机来进行热耗率计算的，由此带来热耗率计算的偏差。
At present heat rate calculate of the double back pressure turbine is according to single back pressure turbine, which brings deviation of heat rate calculate.
但由于提前角减小，排气背压增大，发动机燃油消耗率上升8%左右。
But because of reduced injection timing and increased exhaust back pressure, the BSFC of the engine will be increased of 8%.
