Analogue meters and potentiometers can be replaced by digital meters and non-inductive resistors in the classical ballisticmethod, so it makes wiring and operating more easier.
Based on the wear curve of lands of erosion guns and a calculation method of engraving pressure, an interior ballistic model with the engraving process is established.
以烧蚀火炮的阳线磨损曲线和一种挤进压力计算方法为基础，建立了考虑弹带挤进过程的内弹道模型。
