大家知道,十几年来人们正在大力开展受控热核聚变的研究工作。这项工作要得到成功,其必要条件是在足够长的束缚时间内获得高温的等离子体。根据洛桑(Lawson)的报告,对于常用的氘氘反应,有用的功率输出要求热核聚变的起燃温度T=2×10~8 °K,ρτ>10~(16)秒/厘米~3;对于氘氚反应,则要求T=3×10~7 °K,ρτ>10~(14)秒/厘米‘,其中ρ为等离子体的密度,
We all know that over the past decade people are vigorously carrying out controlled thermonuclear fusion research work. The job to be successful is to have a high-temperature plasma for a long enough time. According to the Lawson report, the useful power output for commonly used deuterium-deuterium reactions requires that the light-off temperature of the thermonuclear fusion be T = 2x10-8 ° K and ρτ> 10-16 seconds / cm -3; For deuterium and tritium reaction, T = 3 × 10 ~ 7 ° K and ρτ> 10 ~ (14) seconds / cm are required, where ρ is the density of the plasma,
