It is widely accepted that the essential mechanism inthe manganese oxides is the double exchange and electric-phonon interaction,whichare intimately related to the lattice distortions of MnO6 octahedra.

目前国际公认此材料中最根本的物理机制是双交换和电-声子相互作用，它们和此材料中载流子的自旋和MnO6八面体的晶格畸变密切相关。

Solar Tracking System" adapts the novel "biaxial realtime sun tracking technique to rotate the systems, optimizing the efficiency by following the sun so that the capacity of energy generation can be doulbed than that of the same-sized first generation silicon solar power system.

追日系统采用最新双轴即时追日技术转动，可追随太阳方向运转达到最大效能，约为第一代矽晶太阳能发电系统相同面积发电量的两倍，在地狭人稠的台湾具发展优势。

Optical quality near stoichiometric lithium niobate doped with Fe2O3 and MnO was grown by top-seed solution method.

在LiNbO3中掺入0.2 mol％ MnO和0.1 mol％ Fe2O3，采用顶部籽晶法生长了双掺杂近化学计量比铌酸锂晶体。

Since the contribution of the spin-orbital coupling interaction of the ligand to optical and electron paramagnetic resonance spectra can not be neglected, the optical and EPR spectra g factors g‖、g⊥ and hyperfine structure constant A‖、A⊥ of LiHSO4:VO2+ crystal are calculated from the high-order perturbation formulas on the basis of double-spin-orbital coupling model and crystal-field theory for 3d1 ion in tetragonal symmetry.

考虑到配体离子的自旋－轨道耦合作用对光谱和电子顺磁共振谱的贡献不可忽略，采用3d1离子在四角对称下基于双自旋－轨道耦合模型的高阶微扰公式和晶场理论公式，理论计算了LiHSO4：VO2+晶体的光谱和电子顺磁共振参量g因子g‖、g⊥和超精细结构常数A‖、A⊥。

This trend depended on the strength of Lewis base sites M=O and activity of lattice oxygen of catalysts.

这一顺序与各催化剂表面的Lewis碱位M=O碱性的强弱、双键晶格氧活性相一致。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
