The results showed that all of them could detect the presence of ZFY DNA sequences except a 46 XX"male"and a 46 XX hermaphrodite, our findings confirmed that Ferguson-Smith〔1966〕 forwarded the hypothesis that the X-Y intercharge model for XX maleness can be regarded as an abnormal exchange initaited in a region proximal to TDF and extending to the telomere,and,also strongly suggested that ZFY gene palyed an important role in sex determining of human.

结果除一例46XX两性畸形，一例46XX&男性&外，余均能检测到ZFY DNA序列(ZFY DNA序列存在于46XX真两性畸形和45XO Turner's综合症，在国内外尚未见报道)。证实了1966年，Ferguson-Smith提出的理论：在父源减数分裂期间，X-Y发生不等交换，导致Y染色体DNA插入性易位。XX男性是由于Y染色体上的TDF基因转移至X染色体上所致。

The metallograph, x-ray diffraction, TEM, EMPA and XPS technigues were used to research the microstructure, phase structure, microhardness, composition, Valence of composed elements, internal stress of coatings, and to measure the wear-resistance and resistance to high-temperature oxidation, too.
