摘　　要：在新能源的研究中,氢能成为与太阳能、风能等一样的绿色能源.分数H原子是在某些特定催化物(如Ar^+)的作用下,基态H原子可以向比基态能级更低的分数主量子数能级跃迁,同时释放出大量能量.通过对氢氩等离子体H原子Balmerα谱线超常展宽的规律性进行研究,探讨这种伴随着大量能量释放的含H等离子体反应的存在性.研究结果表明:利用空心阴极放电管证实高能H原子的存在并首次发现超常展宽与氢氩配比的关系符合催化反应的特点;通过比较研究的方法,在实验上寻找加强含H等离子体反应的途径,得到了更加清晰的H原子Balmerα谱线超常展宽(半高展宽达到0.245 nm).In the study of new energy resource,hydrogen energy has become a green energy the same as solar energy and wind energy.Under the action of certain catalytic materials（such as Ar~＋）,the hydrogen atom of fractional hydrogen plasma can transit from the ground state to the fractional principal quantum number energy levels lower than the ground level,meanwhile the energy is largely released. By the study of the law of Balmerαline＇s abnormal broadening of atomic hydrogen in argon and hydrogen plasma,the possibility of hydrogen plasma reaction with such a large amount of releasing energy is discussed.The research is in two aspects：by using hollow cathode discharge tube,the existence of fast hydrogen is confirmed and the relationship between the abnormal broadening and the ratio of argon to hydrogen is found to be consistent with the feature of catalytic reaction;by the comparative approach and experiments of strengthening reaction of fractional hydrogen plasma,we have obtained the broader Balmerαline＇s abnormal broadening（the half height broadening reaches 0.245 nm）.
