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. Metal atoms fly out liquid surface according to certain way form the atom cluster by the condensing of inert air current, merger and the collision between crystal nucleus pellet and atom cluster form the smoke flame of nanoparticle pellet eventually.

According to the observation of the microstructure of small diameter lumber with scan electron microscope, there are many bordered pits of the radial trancheidal wall in the small-diameter Larch, and most of them have pit film. The resin is not only in resin canal, but also in some trancheid and ray parenchyma cells. The drying defects of small-diameter Larch lumbers were the most severe in consecution heating, fluctuating-heats 2h in between, and drying defects were nearly not observed in fluctuating-heats 6h. There is tylosis in the vessel of the heartwood of small-diameter Cathay poplar. The bordered pits of the radial trancheidal wall are dense, and the pits between vessels are alternate, most of them have pit film. Different collapse happened in all the small-diameter Cathay poplar lumbers. The collapse of small-diameter Larch lumbers was the most severe with consecution heating, fluctuating-heats 2h in between, the least with fluctuating-heating 6h.
