一、试验成功及其意义 1991年11月9日,世界首次核聚变试验在英国牛津的欧洲联合环型实验室(JET)顺利完成。这是一个由欧洲14个国家参加的联合研究项目,10年来共投资10亿英镑,每年年度预算为7500万英镑。这次试验是在密封的环型反应器中进行的。反应器高10米,重3500吨,反应燃料为氘和氚,反应温度高达摄氏2亿度,是太阳中心温度的10倍,反应只持续了几分钟,产生了2兆瓦的能量。核聚变是太阳能源的源泉,从理论上说,受控核聚变有如下优点:原料是取之不竭的;
First, the success of the test and its significance On November 9, 1991, the world's first fusion test was successfully completed at JET in Oxford, England. This is a joint research project involving 14 European countries, with a total investment of 1 billion pounds in 10 years and an annual budget of 75 million pounds. This test was conducted in a sealed loop reactor. The reactor is 10 meters high and weighs 3,500 tons. The reaction fuel is deuterium and tritium. The reaction temperature is up to 200 million degrees Celsius and 10 times the solar center temperature. The reaction lasted only a few minutes and produced 2 megawatts of energy. Nuclear fusion is the source of solar energy. In theory, controlled nuclear fusion has the following advantages: The raw materials are inexhaustible;
