On the basis of characteristics of the basalt and basaltic volcanic breccia from western Pacific Ocean seamount and the composition changes of the vesicle filling,this paper will discuss relation between the overlying cobalt crust and the seamounts basalt.

Thus a study is devoted to the effects of phenol aldehyde resin,butadiene nitrile rubber,air pore filling agent and technological conditions on the preformance of abrasive tools.

The characteristics of cave fillings of carbonates in the Lower Ordovician and their diagenetic environments in northern Tarim basin;

The adsorption capability of activated carbon C40/4 for some organic gases,such as acetone,toluene and methylene dichloride,was studied using micropore filling theory.

For the hardening process of the stabilized soil,a new structural model of stabilized soil was proposed that the structure formation of stabilized soil included soil particle cementing and pore filling.
