Modeling of response curves for explosive elements of same type but different batches

For modeling the response curves of explosive elements with sensitivity property and of same type but different batches, a method has been proposed in this paper with the approach of χ² goodness-of-fit test. The method consists of the identical population test and the goodness-of-fit test for sensitivity response curves, and has been applied to fit the response curve of ^#14 caps of five batches. The theoretical and practical results show that the response curves for explosive elements of same type but different batches may be identical. When modeling the response curves of explosive elements from these batches, it is feasible to use the information provided by all these batches.
