本文用线性回归法拟合实验曲线，提高了汞原子第一激发电势的测量精度。
In this paper, the better measurement exactitudes of the first excitation potential of mercury atom were gotten by using the liner regression method in drawing up experiment curves.
同时对汞原子高能态激发电势进行了测量，讨论了测量条件及其局限性等问题。
Meanwhile the excitation potential of mercury atom in high energy state has been measured and the measurement limitation, as well as the measurement conditions, have been discussed.
