The flow stress-strain response shows the characterization of dynamic recrystallization (DRX), and the peak stress increases gradually with deformation tem- perature decreasing and strain rate increasing. The defor- mation activation energy of the composite for DRX is calculated as 241.864 kJ.mo1-1. The constitutive relation of the composite was got by Arrhenius equation. Further- more, according to the dynamic material modeling and Kumar-Prasad's instability criteria, the processing map was constructed and the unsafe regions for hot deformation were analyzed. Based on the processing map and microstructural evolution, the optimal parameter range for hot deformation processing is 750-863℃ at the strain rate of 0.002-0.013 s-1.展开更多

Methods Fifty patients with chronic pelvic inflammation were treated with abdominal acupuncture and Chinese herbal bag hot compress. The following points were selected as Zhongwan (中脘 CV 12), Xiawan (下脘 CV 10), Qihai (气海 CV 6), Guanyuan (关元 CV 4), Huaroumen (滑肉门 ST 24), Wailing (外陵 ST 26), Daheng (大横 SP 15), and abdominal acupuncture was given once every other day and Chinese herbal bag hot compress was given once a day and 15 days were one course. The clinical effect was observed after two courses of treatment. The observation data included clinical effect, the scoring comparison of main symptoms and signs before and after the treatment. Results Among 50 patients with chronic pelvic inflammation, 11 cases got clinically cured, 15 were markedly effective, and 20 effective and the total effective rate was 92.0%; dropping pain in the lower abdomen, abnormal leukorrhea and gynecological signs were significantly improved after the treatment (P〈0.05). Conclusion Abdominal acupuncture combined with Chinese herbal bag hot compress have the exact effect on the chronic pelvic inflammation.展开更多
