Theoretical analysis emphasizes on heat transfer both inside propellant and between igniter exhaust and internalgrain surface.
理论分析着重研究了点火燃气与推进剂表面传热及推进剂内瞬态热传导规律。

The results indicate that the internal magnetic field has varied obviously with the change of grain size and environment temperature mainly due to collective magnetic excitations.
结果表明，由于集体磁激发现象的存在，随颗粒尺寸和环境温度的改变，样品的内磁场发生了明显变化。
