The anti-jamming ability of igniter depends on the charge in the igniter. The combustion of the igniter charged with barium nitrate and those charged with magnesium powder and PTFE is stable, while the igniter charged with zirconium hydride and lead oxide is unstable. The standard error of duration of the third kind of igniter flame is 523 ms ,and also its nozzle hole is blocked seriously.

The experimental conditions for measurement on the content of aluminium, calcium, magnesium, manganese, phosphor, silicon and titanium using ICP-AES method according to GB/T6730.63—2006 have been tested and analyzed. In the experiments the iron ore sample is decomposed and extracted using sodium carbonate/sodium tetraborate with proper acidity as the flux and then a working curve is drawn up using extremely pure ferric oxide (F2O3) as the primitive. And in the end the correlation coefficient r attains to 0.999 and above.
