Quantum wire (dot) prepared by combination of laser and chemical etching;

The defects of Ti:LiAlO2(100) slices before and after air annealing were investigated by chemical etching and Leitz optical microscopy.

Dislocation pattern and distribution were detected after chemical etching with KOH.

Study on Chemical Corrosion Solution Composition of Carbonized;

It is found that the contents of free silicon and its distribution are the major factors to determining the resistance of chemical corrosion of SiC ceramic.

By testing the mechanical characteristics of different surface of silicon wafer,chemical corrosion is found to be important to improve the mechanical characteristic of Si.

Study on triaxial meso-failure mechanism and damage variables of sandstone under chemical erosion;

The fracturing behaviors of Three Gorges granite under chemical erosion;

The effects of chemical erosion on mechanical behaviors of Xiaolangdi sandstone;

Study on the dislocation of the sapphire crystal with chemical etching;

LaB6 ,as one kind of better material , is so perfect that it is important to research its chemical etching in the arts and crafts to be used in the preparation of emitting cathode.

The defects in GdCa 4O(BO 3) 3 (GdCOB) crystal grown by Czochralski method have been investigated by the phase contrast microscopy combined with chemical etching mehod.

Strength development of Ordinary Portland cement concrete(OPC),air-entrained Portland cement concrete(APC),high strength concrete(HSC) without mineral admixture and high performance concrete(HPC) mixed with mineral admixtures,subjected to the double damage factors(DDF),which were combined actions of freezing-thawing cycles and chemical attack,were investigated.

According the feature of physical and chemic process,the paper divide Casing damage into four types which are cutting 、breaking、 compaction and chemical eroding,and respectively depict their characters.
