Excitations from localized states to the conduction band account for the absorption edge shift toward lower energies observed in the case of N/TiO_2 with respect to pure TiO_2.Mixture of visible light absorption of nitrogen doping and oxygen defect gave no obvious onset in the whole range between 400 and 800nm were observed of the samples N/TiO_(2-)A and N/TiO_(2-)M.

UV-VIS-DRS分析掺杂N/TiO_2结果表明，N/TiO_2-H和N/TiO_2-T两种催化剂在490nm处有吸收带边，可见光激发途径是掺杂的N以填隙方式形成的杂质能级吸收电子发生的跃迁引起的；而N/TiO_2-A和N/TiO_2-M两种方法得到的N/TiO_2在整个可见光区域内具有可见光吸收，没有显著的可见光吸收带边，其对可见光的激发途径是掺杂N和氧空缺共同作用的结果。

A well-known example of an algorithm is Euclid's algorithm, which is a process for calculating the greatest common divisor of two integers m and n.

在运算法则中一个著名的例子就是计算两个整数m和n的最大公约数的欧几里德运算法则。

A desire to elucidate this reaction, and the analogous alkyne metathesis reaction, led to the discovery and development of high oxidation state complexes that contain a M=C or M C bond, so-called alkylidene and alkylidyne complexes, respectively.

为了阐述复分解反应，发现和发展了含有双键和三键的金属有机化合物，分别被称谓杂金属烯烃和杂金属炔烃。

A light rope passes alveolus and stringy head join, a quality is lower end suspension the object of M.

一根轻绳通过小孔和绳头连接，下端悬挂一个质量为 m 的物体。

In chapter 3, the concepts of M-matrix and H-matrix over a commutative Banach algebra have been proposed, and some of their important properties and applications in linear systems over a commutative Banach algebra have been studied. For usual complex matrix, the Bellman inequality with Hadamard product has been proved.

第三章，提出了交换Banach代数上M一矩阵及H一矩阵的概念，研究了其一些重要性质，并给出了在交换Banach代数上线性系统中的应用；对有限维复矩阵，证明了关于 Hadamard乘积的 Bell.an不等式。

We prove that on the localgauge group C∞(M a compact manifold,G a matrix Lie group)there does not exist afinite translationally invariant Borel measure.

我们证明了在局域规范群C∽(M为一紧致流形，G为一矩阵李群)上不存在有限的平移不变的Borel测度。

The current M is a more luxurious-looking boulevardier capable of transporting its occupants in luxury – with a mildly sporty touch here and there.

目前M是一个更豪华的外观花花公子能够运送其占用的豪华-温和运动的联系在这里和那里。

Some valuable works in the paper include: First, based on the algorithm of based-cell detection, the paper presented a dynamic adjustment function on "M" which can work out a problem of outliers fault-making on boundary cell.

总结本文的研究内容，主要有如下创新： 1、在基于单元的孤立点数据挖掘算法基础上，针对边界单元格出现的孤立点误判问题，给出了对M值进行动态调整函数。

Male Wistar rats were exposed daily to radon at a concentration of 100,000 Bq/m(3) for 16 h, and then exposed to 20% cigarette smoke for 1 h for a period of 75 d, with the radon cumulative dose reaching 200 WLM.

雄性Wistar大鼠每日暴露在浓度为100，000Bq/m(3)的氡中16小时，然后暴露在20％的香烟烟雾中1小时，为期75天，氡累积剂量达到200WLM。

First of all, you're on the wrong street. You have to walk more than two blocks to Garvey Boulevard where you'll catch the A-12 bus. Take it about one mile. When you pay the driver, be sure to ask for a transfer; you'll need it. Get off the A-12 at Prescott Avenue and transfer to the M-16 bus going north.

首先，您所在的位置不对，您要走过两条街到嘎威大道乘A-12巴士，乘大约一英里路，付钱时记得问清楚司机如何转车，在浦瑞斯高特大街下车转乘朝北方向的M-16巴士。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
