核工业西南物理研究院的中国环流器新一号受控核聚变实验装置继1996年首次获得2．且秒的长脉冲放电实验后，在今年5月8日的物理实验中又获得3．4秒的长脉冲放电新纪录，引起了世界聚变界的极大关注。这一成果的获得，是核工业西南物理研究院进一步改进和完善国际先进的硅化等真 Nuclear Industry Southwest Institute of Physics, China Circulator New Controlled Fusion Experimental Unit first obtained in 1996 2. After a second long pulse discharge test, another 3.4 sec long pulse discharge record was obtained in the physical experiment on May 8 this year, attracting great attention of the fusion world in the world. The achievement of this achievement is that the Southwest Institute of Physics of the nuclear industry to further improve and perfect the international advanced silicification really
