Low-lying electronic states of the lutetium dimer (Lu2) were studied based on density functional theory using ten different density functionals together with three different relativistic effective core pseudopotentials. Relative state energies, equilibrium bond lengths, vibrational frequencies, and ground-state dissociation energies were evaluated.

用密度泛函理论方法研究了镥二聚体(Lu2)低能量电子态的性质，计算了电子态相对能量、平衡键长、振动频率以及基态解离能，考察了密度泛函性质、相对论有效势种类以及Hartree-Fock交换作用大小对计算结果的影响。

The formation of our 1D nickel wires can be ascribed to the cooperative effect of the reaction rate and magnetic field.The reaction rate in the system is controlled mainly by adjusting the reactant concentration when other reaction conditions are fixed.When the concentration of Ni~(2+) is low,the reaction rate is correspondingly slow,so the complex[Ni(N_2H_4)_x]~(2+) preferentially migrates to the magnetic line of force since paramagnetic metal ions are attracted toward the maximum field.

当反应物Ni~(2+)浓度较低时，反应速率相对较慢，[Ni(N_2H_4)_x]~(2+)优先选择迁移到磁力线附近并且沿着磁力线方向排列，导致电极电势增大，于是[Ni(N_2H_4)_x]~(2+)的化学还原反应也是沿着磁力线发生，结果导致了镍纳米线的形成。

First, the market economy makes some human of desires for material welfare to inflate, the interpersonal relationship easy to fall into the mammonism mire; Next, the market economy causes some people to seek victory attaches the potential, interpersonal relationship easy trend extreme utilitarianism wrong road; Finally, the market economy causes some human of emotions to become estranged, interpersonal relationship faced with serious trust crisis.

首先，市场经济使一些人物欲膨胀，人际关系容易陷入拜金主义的泥潭；其次，市场经济使一些人趋利附势，人际关系容易走向极端功利主义的歧途；最后，市场经济使一些人情感疏远，人际关系面临严重信任危机。

Matal films such as aluminum and silicides are used to form low-resistance interconnections, ohmic contacts to n+,p+,and polysilicon layers,and rectifying metal-semiconductor barriers.

金属片如铝和硅化合物被用来形成低电阻互连， n+，p+的欧姆接，触多晶硅层，并整顿金属-半导体的势垒。

Under drip irrigation, ET was clearly affected by the threshold of soil matric potential and the irrigation frequency.

在滴灌条件下，马铃薯腾发量受土壤基质势下限的影响要比灌水频率的影响大。

According to two_level model of atom, we systematically analyze the quantum reflection and transmission of the vector atomic matter wave with internal structures propagating through a laser beam.

特别是对"粒子隧穿一个势垒是否需要时间"或者"量子隧穿时间是多长"这一问题[14]的讨论在量子力学基本问题研究中一直占有相当重要的地位。

What he does between now and the World Cup is very important to him because I don't think Michael Owen is fully recovered from his broken metatarsal and he might be called upon to do something.

对他来说，最近的表现非常重要。因为我认为欧文不可能从他的跖骨伤势中完全复原，而他很有可能会上场。
