地球人要顺畅驯用太阳之火，必须遵从以下公式:η≥Pb十PL。这个公式表明，在一定质量的等离子体发生聚变反应时，其等离子体的密度、能量约束时间、温度必须满足等于或大于等离子体的辐射功率及其时间内的能量损失功率，热核聚变才得以平衡、维持。
核反应堆，这东西听起来好像很高大上，但实际上，的确就是很高大上。人类第一台核反应堆由著名美籍意大利物理学家恩利克·费米领导的的小组于1942年12月在美国芝加哥大学建造出来，随即将其命名为芝加哥一号堆，该反应堆是采用铀裂变链式反应，开启了人类原子能时代，芝加哥大学也因此成为人类的原子能诞生地。
Thus the symbol 1H refers to the nuclide of hydrogen with a single proton as nucleus. 2H is the hydrogen nuclide with a neutron as well as a proton in the nucleus . Atoms such as 1H， 2H whose nuclei contain the same number of protons but different number of neutrons are known as isotopes. Uranium， for instance， has three isotopes occurring in nature – 238U， 235U and 234U. All have 92 protons in their nuclei. But， whereas the 235U isotope has 143 neutrons in its nucleus， that of the 238U isotope contains 146 neutrons. The stable isotopes are the atoms that are found in the naturally occurring elements in nature. However， they are not found in equal amounts. Some isotopes of a given element are more abundant than others. For example 99，27% of naturally occuring uranium atoms are the isotope 238U， 0，72% are the isotope 235U and 0，0055% are the isotope 234U. As can be seen， all nuclides can be grouped according to number of protons， neutrons and its nuclear energy states:因此符号1H指的是原子核为一个质子的氢核素。
