分析了寿命总体环境因子的概念,说明了这一概念不适用于火工品性能参数,并给出了火工品性能参数环境因子的定义。利用这一结果,可以在一定条件下将火工品在不同环境的试验数据相互折合,从而增加样本量,有利于进一步的统计推断。通过实例说明了火工品性能参数环境因子的应用方法和步骤。 The concept of life expectancy as a whole environmental factor is analyzed, which shows that this concept does not apply to the performance parameters of pyrotechnics and gives the definition of the environmental factors of performance parameters of pyrotechnics. Using this result, under certain conditions, the experimental data of pyrotechnics in different environments can be reduced to each other, thereby increasing the sample size and facilitating further statistical inference. An example is given to illustrate the application methods and steps of environmental parameters of pyrotechnic performance parameters.
