A series of basementinvolved thrust with highangle dipping to southern Tianshan dominate the contractional deformation in the basement. A miniscale imbricate wedge thrust system was developed in the footwall of basementinvolved thrust with a highangle dip, and a basementcored faultedanticline was developed in the hanging wall.

深层断裂变形以向山脉倾斜的高角度基底卷入逆冲断层为主干断层，断层上盘形成冲断隆起，次级断层相对较少，下盘则发育一系列同向倾斜的次级逆冲断层构成楔状叠瓦冲断构造。

The fractal values of the gully's alcoves have close relation to the orientations of gullies and the poleward facing gullies have higher fractal values than those of equatorward facing gullies.

冲沟沟头的分维值大小分布与冲沟的方位关系密切，面向极地的冲沟分维值较大，面向赤道的冲沟分维值较小。

The numerical simulation result indicated that the deformation of protective erodent products film is relatively small, when the following conditions are satisfied, such as the fluid flows from the small inlet to large outlet, the concentric reducer and the relatively small difference of two end calibers of reducer.

以异径管冲蚀失效为例，运用多物理场耦合软件，分析了异径管流体流向、结构和规格对保护膜变形的影响，模拟结果表明：流向为''大进小出''的冲蚀较严重；偏心异径管比同心异径管冲蚀严重；两端管径差越大，冲蚀越严重。

Thermoanaerobacter tengcongensis is a rod-shaped, Gram-negative, anaerobic eubacterium that was isolated from a fresh water hot spring in Tengchong, China. Using a"whole-genome-shotgun"method, we sequenced its 2, 689, 445-bp genome from an isolate, MB4〓(Genbank Accession Number AE008691). The genome encodes 2, 588 predicted coding sequences . Among them, 1, 764 (68. 2％) are classified according to homology to other documented proteins, and the rest, 824 CDS (31. 8％), are functionally unknown. One of the interesting features of the T. tengcongensis genome is that 86. 7％ of its genes are encoded on the leading strand of DNA replication.
