With safety issues playing a dominant role in present-day energetic materials technology, concern is increasing about the relative safety of solid high explosives shocked initiation(SDT) and deflagration to detonation transition (DDT). The critical conditions and parameters have been measured about SDT and DDT, the results indicate that existence coherency apparently between the critical initiation of SDT and DDT in this paper. Some of the results such as the increase velocity of combustion peak, the highest scope and the movement velocity in SDT indicated its existence.
