  The actions of foam plugging and foam stimulating were manifested in-situ test, and the effects of surface foaming method is superior to the methods of subsurface foaming and accompanying nitrogen gas only.

  现场应用体现了泡沫的暂堵和增产作用,且地面起泡方式的效果优于地下起泡和纯氮气伴注方式。

• 近地表

  To detect 3D subsurface Vs structure of engineering site by observing microtremors, must be a powerful tool for development in this subject of Earth Science.

  利用地脉动观测推断工程场地近地表三维速度结构,会为地球科学这一分支的发展提供有力的技术手段。

  Meanwhile, the 2H-W(100) surface system was studied by the extended LEPS method for investigating the subsurface adsorption state effect on the surface adsorption state.

  同时，为了研究内层吸附态对表层吸附态性质的影响，利用改进推广的LEPS方法研究了2H-W(100)表面体系。
