发帖数: 1114 | 1 The energy of most stars results from the fusion of hydrogen nuclei to
helium nuclei. The temperature of the interior of the sun (a typical star)
is 15×10^6K. At this temperature, virtually no nuclei have enough kinetic
energy to overcome the electrostatic repulsion between nuclei and approach
each other closely enough to undergo fusion. Therefore, when Eddington
proposed in 1920that nuclear fuion is the source of stellar energy, his idea
was rejected. Explain why fusion does occur in stars, des |

我觉得是隧传效应吧

你说的对，这道题是要考量子，还真的得说是隧道效应
