Puguang Gas Field as the largest gas field of Sichuan Basin is also the biggest marine carbonate formational gas reservoir.

普光气田是在四川盆地勘探过程中发现的最大气田，也是我国海相碳酸盐岩层系最大的气藏。

Up to now, Puguang Gas Field in the Northeastern of Sichuan Basin as the largest gas field of Sichuan Basin is also the biggest marine carbonate formational gas reservoir.

迄今为止，川东北普光气田是四川盆地勘探过程中发现的最大气田，也是我国海相碳酸盐岩地层中发现的最大气藏。

It is found that the fouling rate is lowered during subcooled fow boiling by carrying gas injection, and the influence of carrying gas injection on fouling of convective heat transfer is more obvious than that of subcooled flow boiling; morphology of CaCO〓 crystallization fouling exhibits self-similarity and the fractal dimensions of CaCO〓 crystallization fouling are determined from the gray scale distribution of the SEM images by box-dimension method. The value of the crystallization fouling surface fractal dimensions reveals the complexity of the surface, and can be used as an import parameter for the investigation of influence of carrying gas injection on scale formation.

实验发现：引入载气，过冷流动沸腾结垢速率降低，但引入载气对过冷流动沸腾结垢速率的影响要弱于对对流传热结垢速率的影响；CaCO〓结晶垢具有统计自相似性，即分形特征；用盒子维法测定了CaCO〓结晶垢的分维值，分维值的大小反映了换热面上生成的结晶垢表面复杂程度，可用于描述引入载气对污垢的形成作用。

The characteristics of non-azide compositions including high nitrogen compounds such as tetrazoles,guanidine,improved thermites,oxidants,binders and process assistants are discussed.Because of their advantages such as adjustable burning rate,nontoxicity and high gas yield,non-azide gas generant to replace azide gas generant will put into use widely.
