The present paper mostly concerned was the T. piniperda which was discovered in Yunnan Province, the research advances on Pinus yunnanensis volatiles and using the volatiles to trap T. yunnanensis were reviewed, the successful experiences of using plant volatiles to monitor and control Scolytidae was briefly summarized.

针对云南纵坑切梢小蠹，综述了云南松挥发性化学成分的研究现状及利用各种挥发性成分诱集云南纵坑切梢小蠹的研究进展，同时简要介绍了国内外其他地区利用植物挥发性化学物质监测和防治小蠹类害虫的成功经验。

The mantle shear zone played an important role in continental blackup. Especially, the dissymmetry caused by simple shear deformation resulted in the different amount of extension in upcrust and subcrust, which in turn formed the detachment of the upper mantle from the crust, that is, the thinning positions of upper mantle and crust were different.

地幔剪切带在大陆裂解过程中起关键性作用，特别是简单剪切变形所产生的强烈不对称构造，以至壳上伸展量明显不同于壳下伸展量，壳幔明显折离，使得壳幔变薄区的位置明显分离，这将能很好地解释华北地台东部岩石圈地幔演化及其浅部盆地形成等的响应。

We have got the following conclusions from the simulation in the thesis:(1) In even diameter hole, the tangental velocity has the characteristic of combination vortex; with the boundary of points for maximal speed, the insides is norm forced vortex, the outside is norm free vortex; the axis symmetry of tangental velocity is very well.
