Therefore, the thermal safety under humidity atmosphere become lower. 1 Introduction Pyrotechnic compositions are mechanical mixtures[1], which composed of oxidizer, fuel, colorant, binder and other materials with special effects.
Although many scholars have studied the thermal characteristics of various energetic materials[3-6], little investigation was queried about the influence of humidity on the thermal decomposition of red pyrotechnic mixtures.

Rotor rotating machinery due to the influence of mass distribution of materials (such as sand holes or stomata in casting), processing errors, assembly factors and the operation of the uneven wear, erosion or deposition and other factors, or a certain fixed parts imbalance caused by loose parts, resulting in some eccentricity between the center of mass and the center of rotation.
