Finally, a certain model of airborne rocket as an example for calculation, the optimum attack conditioncurve about attack distance and dive Angle of armed helicopter is drawn.
最后，以某型航空火箭弹为例进行计算，得到关于距离和俯冲角的最佳攻击条件曲线。

Adopting the definition of indicated relative internal efficiency, the concept of equivalent conditioncurve was proposed and corresponding turbine heat rate model was derived.
采用指示性相对内效率的定义，提出当量汽态线的概念，并据此推导出相应的汽轮机热耗计算模型。

We also give the condition and the arithmetics of the continuity of curve and surface.
