3.Study of the DDT Process of Pyrotechnic Compositions
4.Application of Rain/Snow Enhancement Technology by Delivering Balloon Carried AgI Pyrotechnic Flare
5.Operational technology and economic benefit to enhance rain/snow by delivering balloon carried AgI pyrotechnic flare in Beijing area are described .
6.By mid-afternoon on the 24th, all beaches were clear and the planned pyrotechnic display of demolitions and final naval gunfire began.
7.By analysis and contrast with the mature anti-infrared interferents under aerosphere, on the basis of experiments, expanded graphite is selected as the additive of the pyrotechnic anti-infrared smoke interferents under vacuum;
8.he idea and procedure for developing high efficient AgI pyrotechnics used in weather modification are given in this paper. Two formulations (BR-88-5 and BR-91-Y) of pyrotechnic with high nucleating effectiveness have been obtained after a number of screen tests carried out in 2m3 cloud chamber.
9.An initial check of the spacecraft showed that several pyrotechnic devices failed to fire and deploy the chutes, but the reason for the multiple failures was unclear, Andrew Dantzler, NASA solar system division director, said.
10.9 Inspect the amount, arrangement, fixing position of the signal equipment (Inspect all kinds of signal equipment according to “Navigation signal arrangement and mast structure drawing ” “safe drawing”(such as signal light, signal shape things, signal flag, pyrotechnic signal, self igniting light of lifebuoy, sound signal etc )whether satisfy finished plan, and check the qualified certificate of this equipment before and after installation on the ship.
