| 摘 要： | 用插值拟合和最小二乘逼近拟合方法对高炮射弹飞行时间拟合问题进行了研究.通过对插值拟合公式原理及误差规律的分析,提出确定可用区间的"去值检验"方法,说明了插值拟合公式的应用范围.通过对最小二乘拟合公式实际计算结果的分析,得出了"拟合公式阶数取3为最佳"的结论.对其他口径高炮的射弹飞行时间拟合也基本适用.

| Abstract: | This paper researchs into the problem on fitting the shell flight-time of anti-aircraft gun by interpolation and quadratic approximation.By analysing the interpolation formula principle and the error rule,we put forward "remainder inspection" in available area,and explains to the application range of the formula.By analysing the compute result of the quadratic approximation formula,we educe the conclusion that 3 is the best rank code for the quadratic approximation formula.This conclusion is also applicable for the shell flight-time fit of other antiaircraft artillery. |
