After synthetically calculating the fragment windward area and the measurement data of the speed, we can obtain the initial velocity of the shot and the decay coefficient of the fragment.
对获得的典型弹片迎风面积和弹片测速数据综合计算，就可获得弹丸初速及弹片衰减系数。

While the samples prepared by solution combustion have little surface areadecay, behaving greatly high thermal stability, although they have the least surface area before calcining.
