An integrated network system of MGA (mended genetic algorithms)and BP algorithms has been established. The MGA-BP network's functions consist of optimizing GAperformance parameters, the network's structural parameters, performance parameters, and regulatingthe network's weights using both GA and BP algorithms. Rolling forces of 4-stand tandem cold stripmill are predicted by the MGA-BP network, and good results are obtained.展开更多

In the menopausal stage of women, because of the serious aging of the body ovarian function, ovarian endocrine function will also appear abnormal disorders and the level of estrogen in the female itself body is reduced. Can appear in the afternoon hot flashes or no sweat and ready to emerge, easily excited and agitated, amnesia or tinnitus amnesia, dizziness, mental burnout, backache, hands and feet heart heat, and menstrual dysfunction, menstrual blood volume obviously reduced gradually menopause and other related symptoms, is called "menopause syndrome". The main clinical pathogenesis of menopause syndrome is mostly based on kidney weakness, and is related to the liver.展开更多
