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.
