“托卡马克”这个字是从俄文“环形磁室”中的第一个字母所组成的。这一苏联发明的托卡马克,已被众多的物理学家公认为最有可能实现受控热核聚变的装置。在环形室中,磁场限制了等离子体——离子化的气体——刹那间等离子体的温度和密度便升到原子核发生聚变和产生能量的反应点。世界上最大的托卡马克之一在1986年7月的一次实验得出等离子体的温度达到2×10~8K(200MK)。这一温度是在普林斯顿(N.J.)的等离子体物理实验室中托卡马克聚变试验反应的(TFTR)得出的,这是实验室中前所未有能达到的温度。它十倍于太阳中心的温度,更重要的是这已
The word “Tokamak” consists of the first letter in the Russian “ring magnet.” The so-called Tokamak, invented by the Soviet Union, has been recognized by many physicists as the most likely device to achieve controlled thermonuclear fusion. In the toroidal chamber, the magnetic field limits the plasma-ionized gas-the temperature and density of the plasma in an instant rises to the reaction point at which the nuclei fuse and produce energy. In July 1986, one of the largest tokamaks in the world found that the temperature of the plasma reached 2 × 10 ~ 8K (200MK). This temperature is derived from the tokamak fusion test reaction (TFTR) in the plasma physics laboratory at N. J., which is an unprecedented temperature in the laboratory. It’s ten times the temperature of the center of the sun, and more importantly this already
