提出了一套基于回归分析的火药密闭爆发器燃速压力曲线转折分析方法．对实验得到的燃速压力曲线按指数燃速公式在不同压力区间内分段进行回归拟合，对比拟合的相关系数大小以确定最佳拟合方式．从最后的分析结果可以判定燃速压力曲线是否有转折．该方法具有可靠、准确、方便的特点．但是对于原始数据有较高的质量要求
A set of analysis method based on regression analysis is presented to analyze the burning rate pressure curve of gunpowder closed explosive. The experimental combustion rate pressure curve according to the exponential burning rate formula in different pressure intervals of the regression fitting, comparing the size of the correlation coefficient to determine the best fit. From the final analysis results can determine whether there is a turning point in the burning rate pressure curve. The method is reliable, accurate and convenient. But for the original data have higher quality requirements
