变唇口加杆可模拟具有中心高压区且周向畸变较小的总压分布。
The contour map of small circumferential total pressure distortion with high pressure area at centre can be simulated by the method of the combination of lip and rod.
得到了发动机的周向温度畸变敏感系数，最终确定了对发动机稳定工作影响最大的一组温度畸变参数。
Sensitive coefficients of engine circumference temperature distortion were derived. A group of temperature distortion parameters with most influence on steady operation was finally determined.
试验表明其出口平均总压恢复系数较低，周向总压畸变指数较大，旋流较强且很不规则。
Test results show lower exit average total pressure recovery, larger circumferential total pressure distortion and stronger and more irregular secondary flow.
