Therefore, the energy of π(superscript *) orbit decreases, the probability of optical absorption increases, the n→π(superscript *) electronic transition enhances, and the absorption band broadens and shows red-shift. The above phenomenon will result in the degradation of optical properties of ZnO/silicone white paint under proton exposure.

同时Si-O-Si链内氧原子未成键的孤对电子与邻近硅原子的3d空轨道配位，降低了π轨道的能量，提高了对光吸收的几率，增强了n→π电子跃迁，使吸收带红移，从而导致ZnO/silicone白漆光学性能退化。

The reaction process in methanol solvent can be deduced from the computational results with CPCM solvent model and the supermolecular handling, namely the reaction involves four steps in the methanol solvent. The nucleophilic addition of trimethylamine to acraldehyde generates an enolate. Nucleophilic attack of the enolate on the aldehyde forms the carbon-carbon bond, followed by the proton-transfer process and the further elimination generating the product and liberating the trimethylamine catalyst.

对于CH3OH对反应体系的影响，可以综合考虑CPCM溶剂模型及超分子模型下的研究结果，即CH3OH溶剂中反应按四步进行，催化剂三甲胺首先与丙烯醛发生亲核加成，生成的两性离子中间体与甲醛发生类似于Aldol的醛醇缩合，形成碳-碳键，之后发生分子内质子转移，最后经E1cb消除得到产物，并释放催化剂三甲胺。

ABSTRACT For an infinite soft ferromagnetic elastic crack material, the controlling equation for the plane problem is derived based on the linear theory of Pao and Yeh. Then it is reduced to a biharmonic equation combined with a harmonic equation.

对处于面内磁场中的含穿透裂纹无限大软铁磁弹性体，本文基于Pao和Yeh的磁弹性耦合线性化理论，通过推导，把问题的控制方程表示成一个重调和方程和一个调和方程，而得到问题的复势解。

Nowadays, it is largely used in ironworks and cement plants, etc. If we change its spray gas with nitrogen, improve inlet gas of cleaning tube and bleeder value; it can be fit for gas cleaning in steel-making firms and ironworks.

假如将其中的喷吹气源改成氮气，并将除尘筒内的进气、出料阀进行适当改造，该系统完全可用于炼钢、钢铁厂的煤气除尘，因此本系统具有很广的应用范围。

The result was as much a history (in the modern meaning of the word) as a theory, in that Burnet transformed the hypothetical cosmogony and geogony of René Descartes into a sequence of irreversible events, documented by both nature and Scripture.

伯内特把笛卡尔假设的宇宙形成理论和地球形成理论转换成了既由自然界又由圣经记录的一系列不可逆事件，这样，结合的结果既是一种理论，又同样多地是一种历史（" history "的现代意义）。

By using two groups of cylindrical lenses perpendicular to each other, the marking shape window of semiconductor laser is imaged and rectangle and this imagery is then collimate d to infinite by collimating objective.

利用互相垂直的两组圆柱面镜把半导体激光器的条形窗口成像为矩形。再用球面准直物镜组把此象"准直"到"无限远"。该系统把激光器发出的发散光束压缩到在±0.0025弧度内出射光。两组柱面镜的同种倍率互为倒

It is the unit of memory allocation where a region of RAM is mapped into contiguous logical addresses.

它是内存分配的单位，在这个分配的过程中某个范围内的随机存储器被映射成连续的逻辑地址。

From 1920s up to Now, various techniques and methods for wave field decomposition, propagation and migration/imaging have been well developed, such as the Kirchhoff asymptotic method, frequency-wavenumber domain phase-shift and phase-shift-plus-interpolation methods, and the one-way wave equation based phase-screen and generalized screen methods, etc.

自上个世纪二十年代至今，波场分解、传播与偏移成像技术经历了将近一个世纪的发展，形成了多种不同的方法，如Kirchhoff波动方程高频近似解方法，频率-波数域的相移(phase-shift)方法和相移-内插方法，以及在混合域中基于单向波动方程的相位屏、广义屏方法等。

The reasons of RA focus on disbalance of immunity net, the effect of so many cytokines and MMPs , and the tumor-like proliferation of fibroblast-like synovicytes in joints, though the cause of developing disease is unknow.

RA的发病过程中，免疫网络失衡，加上成纤维样滑膜细胞(fibroblast-like synoviocytes，FLS)的类肿瘤样生长及所分泌的大量促炎性细胞因子、趋化因子和金属蛋白酶，是导致关节内炎性细胞聚集，滑膜细胞增生和向周围组织侵蚀及基质降解和破坏的主要因素。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
