由于遗传密码的简并性，在翻译过程中同义密码子的使用概率不同。

The lowest energy level and degeneracy is discussed.

推导出了三维各向同性谐振子在均匀磁场中的能级表达式并讨论了其最低能级及其简并度的变化。

Following the previouselectronic growth model, a new effect - degeneracy pressure of electrons is taken into account.

在继承以前电子生长理论的基础上，提出一种新的效应—自由电子简并压强效应。

State degeneracy could be broken due to parallel magnetic fields.

磁场会破坏简并度，主要是由於平行管轴的方向所贡献。

For the more complicated case of orbital degenerate ground states, however, the theoretical studies on the spin Hamiltonian parameters are quite few.

同时由于该问题的复杂性，前人工作常常忽略一些因素的贡献，故难以对基态为轨道简并态时的自旋哈密顿参量作出合理的定量的解释。

We also try to give a new definition about the AGB stars. We may refer TPAGB stars as homology AGB stars and the second ignition of hydrogen is an appropriate criterion of the HAGB, since after the second ignition of hydrogen, AGB stars have similar properties and structures: a degenerate CO core covered by double thin burning shells.

我们还尝试着给出一个有关AGB星的新的定义，即可以将热脉动AGB星称做相似AGB星，把恒星是否经历氢的第二次点燃看作恒星是否处于相似AGB的判据，因为在氢的第二次点燃之后，AGB星具有相似的性质和结构：一个简并的碳氧核上面覆盖着两层很薄的燃烧壳层。
