水平管弹状流液膜区的流动特性研究

将一维形式的双流体模型用于水平管弹状流的液膜区，导出液膜区截面含液率随距离而变的控制方程，讨论了方程的封闭性并提出壁面和界面阻力的计算方法．对液膜区平均截面含液率的计算结果与前人的测量结果作了比较，分析了影响平均截面含液率的因素．通过对截面含液率、液相流速和气相流速沿长度变化的计算分析，首次提出液膜和气弹都是连续波．

Determination of risperidone in human plasma by HPLC-MS/MS and its application to a pharmacokinetic study in Chinese volunteers

This study presents a rapid, specific and sensitive liquid chromatography/tandem mass spectrometry （LC-MS/MS） assay for determination of risperidone （RIS） in human serum using paroxetine as an internal standard （IS）. An Alltima-C18 column （2.1 mm×100 mm, 3 μm） and a mobile phase consisting of 0.1% formic acid-acetonitrile （40：60, v/v） were used for separation. The analysis was performed by selected reaction monitoring （SRM） method, and the peak area of the m/z 411.3→191.1 transition for RIS was measured versus that of the m/z 330.1→192.1 transition for IS to generate the standard curves. The assay linearity of RIS was confirmed over the range 0.25-50.00 ng/ml and the limit of quantitation was 0.05 ng/ml. The linear range corresponds well with the serum concentrations of the analytes obtained in clinical pharmacokinetic studies. Intraday and interday relative standard deviations were 1.85%-9.09% and 1.56%-4.38%, respectively. The recovery of RIS from serum was in the range of 70.20%-84.50%. The method was successfully applied to investigate the bioequivalence between two kinds of tablets （test versus reference products） in 18 healthy male Chinese volunteers. The result suggests that two formulations are bioequivalent.
