一个多世纪之前,科学家们就开始探讨太阳为什么会发光。1938年,德国物理学家贝脱雷第一次做出了科学的解释:恒星辐射的能量源泉是聚变反应。在太阳中心数千万摄氏度以上的高温下,不断地进行着氢原子核的聚变反应,4个氢核(氘或氚)结合成一个较重的氦核,并产生巨大的能量,发出光和热。传到地球的太阳能,仅为太阳辐射能的20亿分之一左右。一些科学家从太阳上发生的聚变反应受到启示。40年代初,美国在研制原子弹的过程中,就有人提出利用氢核聚变反应制造比原子弹威力更大的“超级炸弹”。
More than a century ago, scientists began to explore why the sun shines. In 1938, for the first time, German physicist Beretley made a scientific explanation: the source of energy for the radiation of stars is the fusion reaction. In the solar center tens of millions of degrees Celsius above the high temperature, continuous hydrogen fusion fusion of hydrogen atoms, four hydrogen nuclei (deuterium or tritium) combined into a heavier helium nucleus, and generate huge energy, light and heat . The solar energy that reaches the earth is only about 2 billionth of the solar radiation. Some scientists have been inspired by the fusion reactions that take place on the Sun. In the early 1940s, during the process of developing the atomic bomb, the United States proposed the use of proton fusion reaction to make a “super-bomb” that is more powerful than the atomic bomb.
