Scientists say they've successfully produced a nuclear fusion reaction, which replicates the processes that happen on the sun and that they may have found the holy grail of clean energy.

科学家称他们已经成功制造出核聚变反应，复制了核聚变发生在太阳上的过程，将其作为清洁能源的梦想或将变为现实。

《金融时报》 Podcast

Jennifer Granholm said that scientists in California managed to generate more energy from a nuclear fusion reaction that was used to start the process.

核聚变 Nuclear fusion

（重定向自Nuclear fusion reaction）
太阳是主序星，通过原子核的核聚变产生能量，把氢原子聚变成氦原子。在它的核心，太阳发生以每秒钟6.2亿吨氢的核聚变.
核融合反应速度会一直与温度一起上升，直到最大反应速率温度后、逐渐下降。DT反应速度峰值的温度是最低的（约70 keV或八亿度k)，and at a higher value than other reactions commonly considered for fusion energy.

核聚变，又称核融合、融合反应或聚变反应，是将两个较轻的核结合而形成一个较重的核和一个很轻的核（或粒子）的一种核反应形式。在此过程中，物质没有守恒，因为有一部分正在聚变的原子核的物质被转化为光子（能量）。核聚变是给活跃的或“主序的”恒星提供能量的过程。

两个较轻的核在融合过程中产生质量亏损而释放出巨大的能量，两个轻核在发生聚变时因它们都带正电荷而彼此排斥，然而两个能量足够高的核迎面相遇，它们就能相当紧密地聚集在一起，以致核力能够克服库仑斥力而发生核反应，这个反应叫做核聚变。

举个例子：两个质量小的原子，比方说氘和氚，在一定条件下（如超高温和高压），会发生原子核互相聚合作用，生成中子和氦-4，并伴随着巨大的能量释放。

Nuclear fusion 核聚变

（重定向自Nuclear fusion reaction）
The nuclear binding energy curve. The formation of nuclei with masses up to Iron-56 releases energy, while forming those that are heavier requires energy input. This is because the nuclei below Iron-56 have high binding energies, while the heavier ones have lower binding energies, as illustrated above.
The Sun is a main-sequence star, and thus generates its energy by nuclear fusion of hydrogen nuclei into helium. In its core, the Sun fuses 620 million metric tons of hydrogen each second.
Δmc2|, where Δm is the decrease in the total rest mass of particles.[1]

In nuclear physics, nuclear fusion is a nuclear reaction in which two or more atomic nuclei come very close and then collide at a very high speed and join to form a new nucleus. The mass of this new nucleus is slightly less than the sum of its constituents, by an amount known as the "binding energy". This is because the compound nucleus is a lower-energy system (a "more favourable" system energetically) than the two parent nuclei. The binding energy is released as photons (energy). This is the energy that is given off by a fusion process. Fusion is the process that powers active or "main sequence" stars, or other high magnitude stars.
