We have observed gaseous diatomic molecule on the semiconductor surface with the chemical-physics dynamic mechanism of the chemical adsorption on the dangling bond. We explored on the phenomena in how gas molecules dissolve, how the atoms move, and on how they replace the bondings during the chemical adsorption process on the surface.

By means of X-ray diffraction, nitrogen adsorption, UV-Vis diffuse reflectance, a successful isomorphous substitution of titanium in the silica framework of SBA-15 samples with Si/Ti = 50, 25, 20 has been proved, the substitution of Ti for Si does not change the highly ordered two-dimensional hexagonal mesostructure of SBA-15. Titanium is totally tetrahedral and highly dispersed.

The substrates such as galvanized iron,aluminum and some alloys are prone to oxidi-ze and from a compact film of oxidization due to strong activity of metal.The conv-entional putties dont harden completely on the surface of substrates resulting in poor adhesion.

锌、铝等板材及某些合金因金属活动性强，表面易被氧化形成致密的氧化膜，对普通原子灰有效强的阻聚作用，所以普通原子灰在其表面固化不完全，没有附着力。
