Field emission scanning electron microscope, X-ray diffraction and poresizer indicate the nanotubes are formed due to the competition of tin monoxide formation and dissolution under the assistance of electric field. The formation mechanism of nanotubes agrees with the theoretic model of oxidation-dissolution.

经场发射扫描电镜、X射线衍射和孔径分析仪分析显示，阳极氧化的前聚体是氧化亚锡，通过在空气中加热转化为二氧化锡，在详细研究制备条件和氧化锡孔道形貌的基础上，提出了氧化锡纳米孔的生成机理符合氧化溶解理论模型。

During the 20042005 austral summer season, the absolute gravity and relative gravity were measured at the Great Wall Station. The tide gauge was set up in Zhongshan Station in 2000. The SAR interferometry was applied to build the DEM of ice sheet and to monitor the ice flow in the polar region.

A finite element analysis on the new method is presented in this paper. Based on the finite element analysis, tension tests of 18 steel bars in different diameters and holes are carried out. The results of tests, which are according with that of finite element analysis, validate the new method to determine real stresses of steel bars by drilling/enlarging small holes. Furthermore, some suggestions in using of the new method are given.

本文针对该新方法进行了有限元分析，并在此基础上进行了18种不同钢筋直径和不同孔径的带孔短钢筋拉伸试验，试验结果与相应有限元计算结果一致，验证了钻／扩孔确定钢筋实际应力的新方法，并提出了若干工程适用建议。

The stress distribution on the cross section of geotextile with a circle or an ellipse or a square hole under uniaxial tension or double-axial tension was calculated with boundary element method program. The results show that the stress concentration appear at the range from the hole side to about 3 times of the hole diameter, and the degree of stress concentration near the hole is related to the shape of the hole, the size of the hole, the position of the hole and the dimension of the specimen.

用边界元法程序分别对开有圆孔或椭圆孔或方孔的土工织物试样在单向与双向拉伸时孔截面上的应力分布情况进行了计算与分析，结果表明：土工织物孔截面上的应力集中出现在距孔边3倍左右的孔径尺寸范围内；孔边附近应力集中的程度与孔的形状、大小、位置及试样的尺寸有关。
