The results showed that : there were five stages in the rising process of the internal temperature of untreated, fire - retardant solution soaked, and fire - proof paint coated wood during the fire ; the carbonization rate of wood decreased by 21. 1 % ~ 35. 6 % and the rising speed of internal temperature also declined greatly when wood was soaked in fire - retardant solution or coated with fireproof paint ; the carbonization rate of white pine was 8. 5 % ~ 17. 4 % higher than that of the northeast china ash ; for untreated wood, the carbonization rate in tangential direction was 5. 8 % ~ 10. 5 % higher than that in radial direction ; the internal temperature of wood varies with the developing direction of combustion

With the development of modern permanent magnet ( pm ) machine to high speed, high efficiency, high power density and micromation, the limitation of traditional rare earth pm machine is exhibited, such as higher ripple - free torque, higher losses, lower open - circuit magnetic field, etc. halbach motor, a new type permanent magnet motor, first proposed by american scholar klause halbach, has been studied very widely. halbach motor has higher magnetic field, usually as 1. 4 times as that of traditional rare earth permanent magnet machine, which attributes to higher power density
