In addition, the features of elemental geochemistry of all samples suggest that (1) the EarlyTriassic andesitic rocks, characterized by characteristic natures of island arc volcanics, likely erupted in the subduction setting; that (2) the generation of LateTriassic rhyolites with an affinity of Alike granite and synchronously main body granites in the Lincang batholith displaying similar geochemical features, is closely related with the postcollision or latecollision setting; that (3) although the LateTriassic basic rocks partly show island arc volcanics such as highAl contents and NbTa depletion, some of them possessing highMg contents and mostly having traceelement ratios similar to intraplate basalt, which indicates that they erupted in the postcollision rift environment.

元素地球化学特征表明，早三叠世火山岩具有典型的岛弧火山岩的特征，暗示其很可能形成于俯冲的构造环境；中三叠世晚期的流纹岩与临沧花岗岩基主体具有非常相似的地球化学特征，结合其流纹岩具有A型花岗岩属性，表明该区中三叠世火成岩形成于碰撞后的构造背景；而晚三叠世基性火山岩虽然在地球化学特征上显示出与岛弧火山岩相似的高铝和NbTa的亏损，但其中部分火山岩具有高镁和板内玄武岩的微量元素比值特征，说明这些火山岩可能形成于碰撞后裂谷环境。

In the light of field features in desertification areas, the data quality and band combination of different bands are assessed, the indicators, principles and methods for data assessment and band option are put forward to, and optional band combination for desertification monitoring is determined primarily. The data pre-treatment model for desertification monitoring is developed after studying the pre-treatment algorithm of restoration and rebuilding of hyperspectral resolution data. The spectral features and variation rules of different objects in experimental areas are understood and analyzed. The different classified methods are given and discussed on the basis of characteristics of desertification region. The remote sensing quantitative retrieval model for the appraisable factors of desertification monitoring are founded.

The essay tries to probe into internal source of the appearance and development of the movement of Impressionism by analyse the artistical features of traditional painting and analysing the artistical features of Impressionism, Neo-impressionism and Post-impressionism ,to show how the impressionism has developed step by step from the traditional descriptive art whose feature is to emphasizing the natural characteristic of art and the feeling of artist, and to realize that the stage which comes from tradition to morden in history of art never be overlooked.

本文试图通过分析传统绘画的艺术特色，探寻印象主义运动产生及其发展的内在根源；通过分析印象派、新印象派和后印象派的艺术特色来展示印象主义如何从以再现客观世界为特点的传统写实绘画逐步发展到具有现代特征的注重绘画本体特性和艺术家个体主观感受的这一转变过程，从而重新认识印象主义这样一个由传统走向现代的艺术史上不可或缺的一段历史。

A NF2 extended data model with object—oriented features is presented, and its semantics is formally described. The data model has the following features. Its database schema has NF2 extended structures, the data values can be either atomatic or composed by'set'and'tuple'constructors with a fixed order. The'table'concept unifies classes and relations.

该模型的主要特点有：数据库模式是扩展的非一范式结构，数据值既可以是原子的，也可以通过构造符set，tuple以特定的顺序反复复合而成；用表的概念统一了类和关系；对象标识既可以由用户定义，也可以由系统定义。

The internet is atwitter with Google Chrome's innovative new features , but there was no clear winner in our speed test comparing Firefox and Chrome —which means your choice of browser may depend solely on features.

整个互联网都在为了谷歌Chrome的创新功能而欢腾，但是在我们比较Chrome和Firefox的速度测试最终却没有明确谁是胜者——这意味着你对于浏览器的选择将会仅仅取决于它们的功能。

And according to the directions, the Bandelet blocks were classified into two sorts: the Bandelet blocks with geometrical directions and the Bandelet blocks without geometrical directions, and the different characteristics of the two sorts of Bandelet blocks were analyzed in order to distinguish the noise and signal, and the weak contrast features and the strong contrast features.

根据图像增强方向将Bandelet块分为两类：有几何方向的Bandelet块和无几何方向的Bandelet块，并分析了这两类Bandelet块系数的不同特征，从而区分出噪声和信号、清晰边缘和脆弱边缘。

To make a new interpretation of As I Lay Dying by Faulkner, and reveal the carvelesque features of the novel in terms of narration, structure and genre, in the perspective of Bakthins carnivalesque theory, the carvelesque features of the novel can be generalized in three aspectsduality, polyphony and alteration.
