In order to find out the origin cause of the crime, thus achieve the goal of preventing and affect a radical cure the crime, it is very essential that the relation between the personality defect and the crime precaution is probed into.

In fact , it is Han Xin himsetf , or rather his personality defect that caused his tragedy, authough the cruel of the feudal rulers dominated by Liu Bang.

Opinions were put forward that impaired the aging behavior of the basis material was not the photocatalytic effect but the photochemical activity from lattice defect of TiO_2.

The lattice defects in AIN ceramic specimens with different thermal conductivities were observed by TEM.

For there are a lot kinds of materials used in the semiconductor manufacturing process, the stress of wafer will varied widely between layers as a result of different materials at layers, so thecrystal defect may occur.

Crystal etching,a traditional method to study the crystal symmetry and crystal defects,should be a new application in modern mineralogy.

HPHT in the laboratory provides the lattice defects in a brown yellow diamond with sufficient homogeneously oriented pressure and potential energy that are favorable for the dislocation in types Ⅰa and Ⅱa brown yellow diamonds.
