Methods 90 schizophrenics were classified into deficit(n=27)and nondeficit type(n=63)by the Carpenter s Diagnostic Criterion for Deficit Syndrome,their pre-treatment serum prolactin levels were detected with the radio-immunization and differences of serum prolactin levels of same sex intertype compared,and compared with 30 healthy controls.

Concerning the defect research on lithium niobate crystals,some important defect models and the Nb-site-dependent and Li-site-sensitive model are summarized in this paper.

defect model of ZnO Varistor with Nb_2O_5 dopant has been proposed.

The design and implementation of defect testing system(DTS)-a testing system based on defect model was presented.

This paper aims at analyzing the cause and features of some typical defects in the processing of the continuously extruded aluminum tube and providing some precautionary measure

The typical defects in the periodic inspection are introduced,the common problems for DL 647-2004"Inspection code for boiler and pressure vessel in thermal power plant"during executing are analyzed,including the bad pertinence for inspection projects,regarding internal inspection as importance and neglecting external inspection and so on.
