WT5”BZ]The infrared characteristics of the porous alumina films formd in H 2SO 4 solution by AC and DC anodizing have been investigated.

DC ZnO varistors similar with AC ZnO varistors in many ways, especially are differentiated from later in the composition and processing technology.

The studying of preparing Al/Al_2O_3 metal matrix composites with direct oxidation in aluminum melt;

Study on acetic acid production process by direct oxidation of ethylene;

Study on Electrocatalyst of Direct Oxidation of Methane on Anode of Solid Oxide Fuel Cell;

In order to restrain the celluloid preferred growth in the directed oxidation process of Al–Zn–Si alloy and to improve the microstructure of composites, the effect of MgO surface dopant on the oxidation growth process of Al–Zn–Si alloy was studied by thermogravimetric (TG) analysis.

The effect of SiO_2 surface dopant on directed oxidation of alloy AlZnSi at high temperature in air was studied by thermogravimetric experiments.

The composition and microstructures of Lanxide material made from directed oxidation growth of alloy Al-Mg-Si were analyzed by X-ray diffraction, optical microscopy and transmission eletron microscopy.

This article introduces the improved construction and advantage of new conductor,also,the provent measurements of DC magnetism and its dangerous to resistance transformer is put forward.
