Meanwhile, the mixing enthalpies of these five Nb compounds were calculated based on Miedema Model. The results show that the solubility products of Nb compounds in ferrite and austenite meet the following relationship, NbC0.75 〉 NbC0.85 〉 NbC0.88 〉 NbC 〉 NbN and NbN has the minimum enthalpy of formation. It indicates that NbN easily precipitate out, but it is more difficult for NbC0.75.展开更多

METHODS： Pathological changes and collagen depositions were analyzed using morphometry to confirm CCI4-induced chronic hepatitis. At do, d28, ds6 and d84 of the process, the portal perfused velocities （μL/min） in isolated rat livers were exactly controlled with a quanti-fied pump. The pressure （mmHg） was monitored with a Physiological System. The geometric concentrations of phenylephrine or acetylcholine were added to a fixed volume （300 mL） of the circulating perfusate. The equation, the median effective concentration and its 95% confidence intervals of phenylephrine or acetyl- choline were regressed with Prism-4 software in non-linear fit and various slopes. In the isolated perfused rat livers with chronic hepatitis, both median effective concentrations were defined as the pharmacodynamic model of portal hypertension.CONCLUSION： A pharmacodynamic model of portal hypertension in isolated perfused rat livers with chronic hepatitis was defined as the median effective concen- trations of phenylephrine and acetylcholine.展开更多

The image features and accuracy of the diagnosis were observed.Results: after examination, the distance between the scar site and the internal cervical of the test group was closer than that of the control group, and the proportion of the posterior uterus in the test group was much higher than that in the control group. At the same time, there was no significant difference in the size of uterus, endometrial thickness, and follicular diameter between the two groups of parturients after the color ultrasound examination.Conclusion: for the poor healing uterus incision scar parts after cesarean section. The combination of vaginal and abdominal color Doppler ultrasonography has high accuracy and has a certain guiding role in clinical treatment. It can be widely applied in clinic.展开更多
