纯氩 straight argon
- 1964年,用直流钨极氩弧焊及焊丝合金化技术解决了核工业用倾斜式电解糟纯镍焊接。
In 1964, the use of dc argon arc welding and tungsten wire alloying technology solved by tilting electrolysis industry worse pure nickel welding. - 在纯氩气氛中,垂降外特性和双曲线外特性两种电源,都不能在弧长波动时保持工件有效热功率不变。
Only when the arc is intensely constricted by the mixed gas, the power source with hyperbolic external characteristics would then be slightly better. - 利用该系统对纯氩和氩、氮混合电弧等离子体射流进行了测量,获得了射流的原子和分子光谱谱图。
The system has been used to diagnose argon and argon & nitrogenmixed are plasma jet, and good atomic & molecular spectrograms of the jet have been obtained.
