1. A model of pyrotechnical combustion products was established based on the principle of minimum free - energy.

2. Disposal begins with the neutralisation of airbags and other pyrotechnical components.

3. With hard work of fifty years, we developed into the leader in China at the field of pyrotechnical , anti-riot and new concept weapons of chemical defense.

4. The primitive notion of " product" –be it plant, animal, obstetric or pyrotechnical—gives rise to symbols of " progress" in time.

5. Such property parameters contain small volume, short activation time and high energy density. Once the design is finalized, pyrotechnical battery is a perfect power source of shell fuze.

6. A number of vertical line sources was generally caused by catalytic agents, dispersed from falling pyrotechnical flares of an airplane or a rocket.

7. Pyrotechnic cutting principles include metal-jet principle and chemical corrosion principle, Pyrotechnical compounds mainly focus on thermite at the same time adding halogen-containing polymers.
