The following innovative theories and technologies of explosion mechanics which should be developed and adopted for the research and production of explosion nano poly-crystalline diamond have been discussed in this article:computational formula of flying speed of the one-dimensional axisymmetric flyer when the grain explodes in the water;pressure computation model of the new shock waves when they pass through the two-phase powders;space allocation theory when the shock waves pass through the two-phase powders with certain voidage;adiabatic compression theory formed by the effect of shock waves to the trapped air between the gap of powders;the air underneath the flyer can not be discharged from lateral during the high speed flying of flyer,hence adiabatic compres-sion is ultimately formed;theories of catching-up development of the shock waves in pow-ders;the new structural position change model of the phase change of graphite into dia-mond through explosion.
