The results showed that heat treatment had no obvious effect on main linkage way of the system. Between 500℃and 900℃, the crystal phase CaF_2 was precipitated firstly, with the rising of temperature and the prolonging of time, crystal phases such as Al_2SiO_5、Ca_2SiO_4 and Ca_3(PO_4)_2 were precipitated sequentially and the powder was changed from dispersive spheroidic to irregular strip that linked each other, and congregated to irregular mass, gradually.

热处理对体系的主体键连方式无明显影响；在500-900℃温度范围内，粉体优先析出CaF_2晶相，随着加热温度的升高及保温时间的延长，依次析出Al_2SiO_5、Ca_2SiO_4、Ca_3(PO_4)_2等晶相，粉体由分散的近球形颗粒转变成相互粘连的不规则带状，并逐渐聚合成不规则块状；固结体抗压强度逐渐增加后趋于平缓。

rametes versicolor理时间的延长可改善磨浆性能。

The results indicate that the extent of reduction and carburization was intensified by prolonging the reduction duration or by increasing the reduction temperature. The catalyst activity and stability was enhanced with the reduction at 270℃ compared with those reduced at lower temperature (240℃) or unreduced samples.

结果表明，在240℃延长还原时间或将还原温度升高到270℃均有利于催化剂的还原，270℃还原的催化剂的活性和稳定性明显高于未还原和240℃还原的催化剂，催化剂的运行稳定性与催化剂在反应过程中的流失量有密切关系。

The infrared radiation characteristics of unsymmetrically two dimensional nozzle are experimentally studied. UTDN is designed and manufactured by prolonging one broad side of a general two-dimensional nozzle AR8 and its aspect radio is 8. Temperature distribution on the axes and spectral IR intensity on the orientation of 0, 10, 30, 60 and 90° on three typical detective planes of the hot plume are measured on hot plume simulation platform of the turbo fan engine.
