摘要
介绍了φ１１８ｍｍ标准发动机装药在不同自然存放天数下，其燃速随着自然存放天数增加呈现出上升的规律性。通过数理统计分析确定了存放天数指标，并在批量生产中有效地控制了全尺寸固体发动机燃速性能。
introducing the law about rise of the burning-rate of the grain in φ118 standard engine with the increase of days of natural store. Determining the index of days through the analysis for mathematical statistics, and controlling effectively the burning-rate performance of the full-size solid engine.
