The article reviewed the synthetic method and it\'s development of the low insensitive high explosive -1 -Methyl -2,4,5 -trinitroimidazoles, and introduced the progress in preparation of MTNI which was used by imidazole, 2,4-dinitroimidazole, and 1-methylimidazole.

Based on references,synthesis methods of insensitive explosive TATB are summarized.

Based on the insensitive principle,cohering principle and the influence of the proportion of ingredient on the safety,a new kind of insensitive explosive is developed with PETN as primary material and with wax,polyisobutylene and black lead as desensitizers and adhesives.

In order to explore new insensitive explosives,composites based on 3-nitro-1,2,4-triazol-5-one(NTO) were reviewed.

A new reaction rate model for simulating the detonation process of the insensitive high explosives;

The shock-to-detonation transition (SDT) of insensitive high explosives (IHE) is researched in this paper.

Numerical simulation for overdriven and shocking-to-detonation transition of insensitive high explosives;

The local normal detonation speed Dn of insensitive high explosive is closely relative to the local total curvature κ.

The modified JWL equation of states(EOS) of the products and Hybrid reaction model are used to obtain the matching relation between artificial viscosity and mesh size of PBX9502 of insensitive high explosives and are compared with(other) reaction models.
