The thermal degradation results indicated that the γ-Al2O3 coating film obviously enhanced the anti-thermal degradation property.

Mechanism of chromaticity y-value shift during thermal degradation of BaMgAl_(10)O_(17):Eu~(2+) phosphor;

For BAM,a serious thermal degradation takes place after annealing in air.

In additional, the thermal degradation of BAM phosphor and the effect of organic addhesive on secondary properties were discussed.

By studying and summing up the common failure physical models and combining with the quantum mechanics theory on the relationship between the electronic equipment aging reaction rate and tempreture-humidity,a hygrothermal aging life model for solid propellant storage and usage is established with the propellant mechanical properties as the research object.

The hygrothermal aging behavior of the CF /epoxy NOL rings in distilled water at 35℃, 55℃, 65℃and 75℃was analyzed in terms of the absorption characteristics, static and dynamic mechanical properties.

In this paper, the standard accelerated hygrothermal aging spectrum for military aircraft composite structures is given based on the domestic climatic environment and the developing aircraft properties, and the aging effects for our composite material system are systematically studied, and the conclusion for guiding and modifying the structure design are given.

Chlorosulfonated polyethylene (CSPE) bang is ed as moistureproof layer of which niternal wall of industrial bang tower is Under damp & heat aging environment.
