A vivid example of this: in the two deuterium nuclei polymerization into a helium-4 nucleus, it seems quality is not conservation, is the quality of helium-4 nucleus does not mean that two of the deuteron and quality.
这个例子生动地说明：在2个氘原子核聚合成1个氦4原子核时，似乎质量并不守恒，也就是氦4原子核的质量并不等于2个氘核质量之和。

Luminosity of the Sun , using its own gravity to put hydrogen Rafah , by the nuclear fusion of hydrogen into helium nuclear thermonuclear reaction enormous energy to the radiation from the surface of the internal transfer , launch into space .
太阳发光时，利用自身的重力把氢拉向中心，由氢核聚变成氦核的热核反应产生巨大的能量，以辐射的方式，由内部转移到表面，再发射到宇宙空间。

This energy is librated at the center of the Sun as billions upon billions of nuclei of hydrogen atoms collide with each other and fuse together to form nuclei of helium, and in doing so, release some of the energy that is stored in the nuclei of atoms.
数十亿计的氢原子核在太阳的核心碰撞并且聚变生成氦。在此过程中一部分原本储存于原子核中的能量被释放出来。太阳所产生的光和热需要每秒将六亿吨氢转化为氦。

A planet on the other hand is built up out of the dust that surrounds a star. When a star is formed there is still a disk of gas surrounding it. As this gas cools, it condenses and forms solid grains. These grain particles accrete into large bodies called planetesimals, which then collide and accrete to make protoplanets. These protoplanets evolve into planets like the planets in our own solar system.
行星演化与恒星不同：恒星形成之后，周边的气体尘埃云冷却之后凝结形成，成为行星雏形，众多小行星雏形聚合碰撞，演化成成熟的行星；没有内部的核聚变；质量超过木星13.6倍，就会产生核聚变，如果还未至木星86倍，尚处于棕矮星的阶段，将会向恒星演化；持久的核聚变需要足够大的质量来支撑，温度也不足支撑氢向氦的转变。
