For reducing boundary distortion area, the elevations of grid DEM are viewed as a discrete sequence under a generalized coordinate, so that the boundary problem of two-dimensional discrete wavelet transform is turned into the boundary problem of one-dimensional discrete wavelet transform, which not only greatly reduces the boundary distortion area, improves the precision of reconstructed DEM data near the boundary, but also decreases the number of zeros adding on the boundary for wavelet transform, and boosts the compression ratio. On the basis of analyzing the distribution characteristics of coefficients in low and high frequency bands, a mixed entropy coding plan is applied, and a high efficient quantizator called"self-adaptive hard threshold"is established, which is helpful for improving the precision of the reconstructed DEM data and for enhancing compression ratio.

为了减小小波变换山区格网DEM数据压缩中边界失真区域，将山区格网DEM高程值视为广义坐标下的离散随机序列，把二维离散小波变换中的边界问题转换为一维离散小波变换中的边界问题，不仅大大减少了小波变换边界失真区域，提高了重构DEM数据边界点的精度，而且减少了边界补零个数，提高了压缩比；通过对山区格网DEM数据小波变换低频区和高频区变换系数分布特点的分析，采取了霍夫曼—游程混合熵编码方案，设计了高效、低失真的"自适应硬阈值"量化器，即对低频区变换系数不进行量化，直接进行霍夫曼编码；对高频区变换系数则先用"自适应硬阈值"方法量化处理，再进行游程编码。

Pronounce to replace an English to translate to have a few advantages with the Chinese language:A, simple go easily, so easily popular;Two, the Chinese language pronounce to translate to be advantageous to the only sex which promises a business enterprise particularly more than the English;Three, the blindness may conflict with the taboo of a certain consumption community place country after translating the meaningful English phrase, resulting in bad result, but adoption to foreigner the milli- nonsense Chinese language pronounce but can avoid this kind of phenomenon availably.

用汉语拼音来取代英译有几个好处：一、简便易行，所以容易流行；二、汉语拼音比英译更有利于保证企业专名的唯一性；三、盲目译成有意义的英文词后可能会与某个消费群体所在国的禁忌发生冲突，造成不良后果，而采用对外国人来说毫无意义的汉语拼音却可以有效地避免这种现象。

The sliding mode control, which is better than the linear quadratic optimization, achieved ideal control result by using comparatively less external energy. The sliding mode control method is valuable to study.

基于模态分析的滑动状态控制比线性二次最优控制用较少的外部能量可得到较好的控制效果，基于模态分析的滑动状态控制是一种有研究、开发价值的控制算法和控制方法。

Thirty-two tears later, with the hindsight of historical perspective and a life of practicing social research on cities, the answer is: yes, there was; no, there is currently not; but perhaps, with luck, it will resurge in the twenty-first century, with new concepts, new methods, and new themes, because it is more necessary than ever to make sense of our lives.

三十二年后，现在回过头来看这段亲身对於城市的社会研究的参与经验，答案是：有，不过是以前有；没有，现在没有；但是，如果幸运点，会在廿一世纪复活，发展一些新的概念，新的研究方法，以及新的主题，因为都市社会学对於我们对生活的理解比过去更显必要。

Abu Hurairah reported that: The Messenger of Allah said:'The reward for Salat performed by a person in congregation is more than 20 times greater than that of Salat performed in one's house or shop.

艾卜，胡莱勒的传述：他说：安拉的使者说：一个人跟随集体的拜功比他在公共场所和家中礼拜的拜功高过二十多个昂级。

Based on limiting the tensile strain at the bottom of the asphalt layer and the vertical compressive strain at the top of the subgrade, the suitability of layer thickness is checked by two criteria. One is controlling the maximum surface deflection under the design load, and the other is controlling the modulus ratio between adjacent unbound aggregate base and subbase layer.

该方法基于限制沥青层底的拉应变和路基顶面的压应变，采用两个准则来校核所设计的沥青层厚度的适宜性：一是控制设计荷载作用下的最大路表弯沉；二是控制相邻两个无结合料处治的集料层的模量比。

CH3OH could attack the phosphor atom in 1,3,2-dioxaphopholane of compiound (1) to give O-methyl O-hydroxyethyl-O-phthalimidoethyl thiophosphate in 85% yield; in the presence of potassium hydroxide aryl selenol could attack the carbon atom in 1,3,2-diox-aphopholane of the cyclic phospholipid conjugate of N^1-(2-furanidyl)-N^3--5-fluorouracil to give the corresponding product of ring-opening in high yields.

在室温下，以异丙醇作溶剂，苯硒酚与化合物2不反应。在氢氧化钾存在下，以异丙醇／水作溶剂（体积比20：1，在室温下，硒酚可以有效地进攻中化合物2中1，3，2-二氧磷杂环戊烷中的碳原子生成相应的开环产物。按照这一反应条件，顺利实现了硒酚对N^1-（2-呋喃基）-N^3-羟烷基-5-氟脲嘧啶硫代环甘油磷脂缀合物的亲核开环，生成甘油骨架的端碳原子上带有芳硒基新颖的磷脂核苷缀合物。

Bonderman (10-7) allowed seven runs and eight hits in 5 2/3 innings, walking four and striking out none. He surrendered a two-run double up the left-center-field gap to Hideki Matsui in the first inning, one of three hits for Matsui, who has hit safely in 44 of 48 games and appears to be taking to the designated hitter spot -- sporadic as it may be -- with aplomb.

T； X1 F9 D1 h$ N王建民加油站棒得慢(10胜7负)在5又2/3局投球中丢了7分，保送4次，没有三振，他在第一局就被马猪蚁打出一支两分打点的左外野二垒安打，这是马猪蚁这场比赛3支安打中的1支，他在48场比赛中有44场击出安打，显示出他已经可以沉著地适应指定打击的工作(偶尔需要他担任指定打击的时候)。

Although the ion-exchange capacity of membrane quaternized by methyl iodide is higher than that of membrane quaternized by methylene diiodide,mechanical properties of the former are too poor to form membranes.

以一碘甲烷为季铵化试剂制备的离子交换膜其离子交换当量要比以二碘甲烷为季铵化试剂的要高，但机械强度差。在相同条件下，提高反应温度，有利于膜的季铵化反应，而不利于膜的磺化反应。

Modified sepiolite is a kind of fibriform clay mineral with abount of magnesium, it has the advantages of stronger adsorption, larager ion capacity for its special samdwich structure, causing less repollution, and can be reused, so it will be widely used in pollution control.

改性海泡石是一种纤维状富镁粘土矿物，其独特的层状结构和巨大的比表面使其具有吸附性强、离子交换能力大的特点，且具有二次污染小、可重复使用的优点，因此在污染治理方面的应用较为广泛。

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。
