U(4) algebra is very suitable to describe triatomic molecules, for their Fermi interaction can be described by using nondiagonal matrix elements of Majorana operator.

在研究多原子分子的李代数方法中，尤以U(4)代数适合描述三原子分子，这不仅仅是因为U(4)代数完全描述的是三维情形，物理图象更加清晰直观，而且，U(4)代数的Fermi相互作用可以由Majorana算子的非对角元素给出，不需要再引进另外一个代数。

Our model is obviously superior to Rinker'smodel. because Rinker's model potential is a combination of Thomas-Fermi-Dirac potential and Hartree-Fock-Slater potential for the isolated ion.

我们的模型明显优越于Rinker的模型在于： Rinker的模型采用的是Thomas-Fermi-Dirac势和自由原子的Hartree-Fock-Slater势的迭加形式，而我们的模型中除离子的结构因子外，电子散射势、化学势及电离度等量都是通过自洽迭代方法计算的。

The finite DOS at Fermi level means that there are free carriers, i.e., a modulated electric field could change a semiconducting graphene into a semimetallic one.

值得一提的是，态密度中对应费米能为零的有限值代表著自由电子的存在。换句话说，藉由调制电场的影响可以将单层石墨系统从半导体性变成金属性的系统。

The results of Knight shift and spin-lattice relaxation time (T1) provide us that there are no correlation between the density of states at Fermi level and the superconductive transition temperature of the studied material.

藉由奈特位移及自旋晶格松弛时间的量测结果，我们得知对於我们所研究材料的超导转变温度和费米面上的态密度无关。

Chapter 4 introduces the calculation method of Fermi resonance levels forlinear triatomic molecules.

第四章介绍线形三原子分子Fermi共振能级的计算方法。

The calculation of Fermi resonance energylevels of linear triatomic molecules is the unavoidable problem in the calculationof molecular vibrational energy levels.

线形分子Fermi共振能级计算是分子振动能级计算必然涉及的问题。

However, Fermi resonance is an important role in the intramolecular vibrational energy transfer process, so we use the bend triatomic molecule model described by potential energy calculated from U(4) algebra, and the chaos of high excited molecular vibration can be studied by analyses of the intramolecular vibrational energy transfer process.

Fermi共振相互作用作为分子内能量转移的一种机制，在描述分子激发的完全振动方面有着重要的作用，因此，我们在构建弯曲三原子分子模型时引用了U(4)代数方法获得的势能面，从能量传递角度研究体系的混沌性质，是在多原子分子激发态领域研究非线性问题的合理延伸。

Complementing thesediscoveries, Fermi has detected a steady glow of gamma rays from theglobular star cluster 47 Tucanae, as described on page 845 (3); this region is thought to harbor dozens of millisecond pulsars.

除了这些发现，费米还探测到了杜鹃座47球状星团的一个稳定的伽玛射线余辉，如845页文中所述。人们认为这个区域藏有许多的毫秒脉冲星。

We report the detection of gamma-ray emissions above 200 megaelectron volts at a significance level of 17sigma from the globular cluster 47 Tucanae, using data obtained with the Large Area Telescope onboard the Fermi Gamma-ray Space Telescope.

根据Fermi伽玛射线空间望远镜的大面积望远镜数据，我们报道对于球状星团47 Tucanae的伽玛射线发射的探测，Fermi的探测结果在200 MeV以上达到17sigma的显著性。

As of Tuesday, Google's results were still censored in China.

截至周二，谷歌的搜索结果仍受中国审查。

In order to make the positive action increase and negative one decrease, the sub-forces of the social factors must be adjusted to form a centripetal force.

在这一过程中，人的主体性发挥是社会有机体健康发展的灵魂。
