Effect of SLS Processing Parameters on Curl Deformation and Honeycomb Defects of Specimen in Composite Wax Powder;

In allusion to leakage blockage method by sticking of pore defect, the calculation process of toughness stress strength factor in the glue interface is given through the bulge test model analysis, and the critical bulge radius of split crack inter-cohesion break of epoxy resin glue is evaluated by means of brittle break criterion of break mechanics.

We firstly explained that the electromagnetic wave emitted from the source under the condition of far field is approximately the plane wave, which vertically downwards; and then under the condition of far field, we detail in studied the CSAMT response characteristics when there are different types of the hole lacuna in depth, in size, in shape, in silting (mud silting.

Neutron testing method for detecting cavity defect of pour concrete under steel plate lining;

At the same time,the effect of hydrogen annealing on the reduction of void-type defects in CZ silicon is also summar,zed.

Its’ still in dispute that whether the flow pattern defects(FPDs) are void-type defects.

The magnetic field technology that pulls large diameter single-crystal silicon, the control and utilization of defects in the silicon wafer, the grown-in void defects in large diameter single-crystal silicon, the silicon epitaxial wafer and SOI wafer, the analog computation of the growth of large diameter single-crystal silicon and solar cell single-crystal silicon and the research about phys.
