查询词典 liquid air

In the electromagnetic field that countercurrent inductor produces, the metal droplet that melts gets the role suspension of electromagnetism force in quartz pipe center and had been heated up continuously. When metal droplet of melting have been heated up certain temperature surface beginning gasification, metal vapor tension will raise follow temperature go up, is heated continuously can have plenty of metal atoms overflow metal ball liquid surface, at the same time, as the inert gas of cooling medium, all along with certain current velocity, sideswipe the metal droplet surface that melts.
