Therefore,costume polytechnic needs to take the actual combat education mode to foster students' ability on art creation,practice handling ability,acclimatize themselves to the real market to achieve its education goal.

The evaluating validity of firearm lifetime is dependent on the scientific and rational determination of both the indexes,which must be based on actual combats.

In actual combat,because of the warhead velocity relative to the target and the fragments initial velocity gradient in existence along the warhead axial,the fragment dynamic ejection angle will be recomposed,the fragment clustering may disperse,and the fragment density on the target will decrease greatly.

Based on the analytic hierarchy process and fuzzy synthetical evaluation theory,a valuation index system and valuation analysis calculation model which is used to evaluate the level of actual combat training of the ground radar EW on air defense battle is built up.
