查询词典 metal

Results of experiments under different conditions show that, compared with arc electrical signal and arc light signal, arc spectrum signal is of more advantageous property. It can not only detect short-circuit metal transfer, but also more effectively detect droplet in free transfer mode than electrical signal. It can not only detect the droplet transfer in the CO〓 welding, but also can detect spray transfer in Ar welding with advantage over arc light signal. Especially, its outstanding capability of detecting steam spray transfer where other approaches fail, shows that are spectrum information has the utmost signal quality in metal droplet transfer detecting.

多种工艺条件下的对比实验表明，与电弧电信号及光强信号相比，电弧光谱信号具有更为优越的信号品质，其不仅可以检测熔滴短路过渡而且优于电信号可以有效地检测自由过渡；不仅可以检测活性气体保护条件下的熔滴过渡，而且优于光强信号可以检测惰性气体保护条件下的喷射过渡，特别是其可以实现熔滴射流过渡的检测，解决了这一用其它信号无法克服的难题，体现出电弧光谱信息在熔滴过渡研究中所独具的优越性。

Project Content and Scale: To adopt a mixed production transmission device of micro glass powder such as axle bush, the anti-abuse movement capacity of gears can be raised 2-3 times, especially in the condition of high-temperature without lubricant .About 70% of the world automobile gear is made in the way of metal powder metallurgy.
