例句與造句

1. It is supported only by electron degeneracy pressure, causing it to be extremely dense.
2. However, in a white dwarf, the electron degeneracy pressure doesn't increase very quickly as mass increases.
3. In white dwarfs, which do not undergo nuclear fusion, an opposing force to gravity is provided by electron degeneracy pressure.
4. The neutrons resist further compression by the Pauli Exclusion Principle, in a way analogous to electron degeneracy pressure, but stronger.
5. Rather, the intense gravitational attraction of the compact mass overcomes the electron degeneracy pressure and causes electron capture to occur within the star.
6. It's difficult to find electron degeneracy pressure in a sentence. 用electron degeneracy pressure造句挺難的
7. The acceleration is caused by the same forces that one normally thinks of as keeping the Earth's size fixed, namely electromagnetism and electron degeneracy pressure.
8. Electron degeneracy pressure provides a rather soft limit against further compression; therefore, for a given chemical composition, white dwarfs of higher mass have a smaller volume.
9. There is an upper limit to the mass of an electron-degenerate object, the Chandrasekhar limit, beyond which electron degeneracy pressure cannot support the object against collapse.
10. Should the white dwarf's mass approach the Chandrasekhar limit of 1.4 it will no longer be supported by electron degeneracy pressure and it will undergo a collapse.
11. Another criterion for separating planets and brown dwarfs, rather than deuterium fusion, formation process or location, is whether the core pressure is dominated by coulomb pressure or electron degeneracy pressure.
12. In massive stars, the core is already large enough at the onset of the hydrogen burning shell that helium ignition will occur before electron degeneracy pressure has a chance to become prevalent.
13. Another criterion for separating planets and brown dwarfs, rather than deuterium burning, formation process or location, is whether the core pressure is dominated by coulomb pressure or electron degeneracy pressure.
14. The physics of degeneracy yields a maximum mass for a non-rotating white dwarf, the Chandrasekhar limit approximately 1.4爏olar mass beyond which it cannot be supported by electron degeneracy pressure.
15. It is clear enough to me that there is electron degeneracy pressure because electrons can't have the same quantum state ( whyever that is, the Pauli exclusion principle as observed ).
16. In all massive stars, electron degeneracy pressure is insufficient to halt collapse by itself, so as each major element is consumed in the center, progressively heavier elements ignite, temporarily halting collapse.
