31. When Na-Naphthalene solution, O2 and N2 plasma were used to the hydrophilic modification of the PTFE micropore membrane, the binder would have adhesive power to the membrane in varying degrees.

32. At room temperature and atmospheric pressure, using O2 as an oxidant, HBr and tert-butyl nitrite as catalysts, selective oxidation of a broad range of sulfides was achieved.

33. At first, we study the first step of the reaction between dimethysulfide(DMS) . We think that the O2 aggress the sulfur atoms on the dimetysulfide(DMS).

34. The experiment results show that this new method to oxidate the combination of H2 and O2 is very easy in use and can improve the uniformity greatly.

35. Results indicated: Formocresol, Eugenol and Guaiacol all had a strong function of scavenging (O2) and antioxidation. However, the function of Guaiacol was weaker than that of other two.
