进气道特性 meaning in English

inlet characteristics

On the study of supersonic inlet optimization algorithm , first , the inlet performance curve is converted to facilitate curve interpolation . then , with this converted performance curve , inlet optimization problem is converted to a simple nonlinear constrained optimization problem
在对超音速进气道进行优化时，首先对进气道特性进行适当变换，然后利用变换后的特性，将进气道的优化问题转化为一个易于求解的单变量约束非线性优化问题进行求解。
