Abstract: We have known that the fixed star mainly depends on the thermonuclear fusion to gain the energy in order to evolve continuously. In this paper, a new basic principle of the thermonuclear fusion and sidereal evolution has been expounded. Simply, it is the processes that, the electrons bombard into the light nuclei (H, He, Li, Be, B, C etc.) to yield the neutrons, which are going to be captured by the others light nuclei; and then, the nuclei which accept the neutrons are incessantly evolving into various nuclides including varied compound super-nuclides; thus, varied heavy nuclei are existing in the thermonuclear fusion as the super-nuclides make the β decays etc. Meanwhile, the elementary particles that come from the decays will return to take part in the new thermonuclear reactions again, and cause the light nuclei to cycle with extending gradually to all nuclei including varied super-heavy nuclides. In fact, the processes of the thermonuclear fusion are very complicated, the nuclei cycles are caused by the elementary particles bombarding. The model of the proton cycles and the carbon cycle is fairly imperfect to explain the thermonuclear fusion, so it is very necessary to found the double cycles model of the thermonuclear fusion, namely multi-nucleus cycling even including developing down to all nuclei cycling of depending on the elementary particles cycling and bombarding.

In deed, almost all kinds of nuclear reactions including that we have not known can exist synchronously in the thermonuclear fusion of the fixed star, though the effective probabilities of various reactions are more different. It is very clear that, the double cycles system of the thermonuclear fusion already make the vast universe organically come into full contact with the particles in the microcosm. This systemic model also explains the source and formation of varied nuclei, the evolvement processes of the fixed star is right the processes of birthing and growing of varied nuclei. These thoughts should have the important reference to studying the evolvement of the universe.

In the fixed star, there always are lots of various electromagnetic fields to accelerate varied charged particles, and create plenty of the small group bodies of heavy super-nuclides. The existence of the huge and powerful electromagnetic fields is the result of that, the large quantities of plasma clouds are produced continuously, and disturb and combine with each other. Even some plasma clouds can make the stream group of charged particles twist. These plasma clouds can always create the violent collision and cause the violent nuclear reactions. Meanwhile, each nuclide including super-nuclide must have a particular magnetism, which has undoubtedly the important influence for the formation of super-heavy nuclides bodies. It should be insisted that, the essence of the gravitational attraction is the effect that varied hard density particles including from varied hydrogen super-nuclides to large super-uranium super-nuclei even including heavy super-neutrons are continuously produced out and grown up and accumulated in the quite limited space by the thermonuclear reactions. The gravity is the show of the systemic inertia, but which is gained only through the thermonuclear fusion.

We have known, everywhere there are various dark nebulas to be maintained by plasma in the universe, and these nebulas are always in the irregular motion. Plentiful and varied elementary particles are also the base of that the fixed star is evolving from the birth to the death. The γ-rays bursts are directly the showing that two dark nebulas or more nebulas have collision with each other, and varied nebulas can combine to grow up through their collisions. So, the cause of birthing fixed star is just that two huge nebulas collide each other in the universe. The sidereal evolvement has direct relation with the amounts and energy of the elementary particles. And all planets and comets and such celestial bodies must go through the thermonuclear fusion. Besides, the evolving processes of fixed star are also described in detail in this article. All these thoughts could have special reference to the study of cosmic evolvement.
