与传统的活性金属钎焊不同，它采用的是一种高温下形成液相的氧化物-金属钎料，并且钎焊过程不需要真空或惰性气氛保护。
Different from the traditional active metal brazing, RAB uses a liquid-phase oxide-metal melt at high temperature and the process does not require a vacuum or inert atmosphere.
结果表明，固化气氛对酚醛型氰酸酯的反应活性有着显著的影响，在空气气氛中的凝胶时间远小于惰性气氛的凝胶时间。
The results showed that the gel time of uncured resin could greatly affected by ambience, which is much shorter in air than in an atmosphere.
本发明反应温度较低，反应时间较短，无保护性气氛，活性炭比表面积较高。
The method has such advantages as low reaction temperature, short reaction time, no protective atmosphere and large specific surface area of the obtained activated carbon.
