【Abstract】 By means of heating an experimental gas in a shock-tube, under the condition of Mach-number M = 8-9, the strong reversed lines of Ca3933.666A, Ca 3968. 468A Ca 4226.728A A13944.032A A13961.527A Na5893A have been obtained. of these reversed lines, the reversed lines of the aluminum are discovered for Al first find. In this paper, the mechanism of the reversed line in a shock-tube has been discussed.更多还原
