采用高效液相色谱法,以β-环糊精为手性固定相拆分奥丁尼酮洛芬缓释胶囊中酮洛芬对映体,并对流动相中甲醇的含量、流动相的pH值、缓冲盐的浓度等色谱条件对拆分结果的影响进行了探讨.结果表明,在柱温为25℃,pH值为4.0,采用0.01 mol/L的磷酸二氢钾缓冲溶液,甲醇40%(V/V)作流动相时,奥丁尼酮洛芬缓释胶囊中的酮洛芬对映体能达到较好分离. 相似文献

On stochastic optimal control of partially observable nonlinear quasi Hamiltonian systems 总被引:1,自引:0,他引:1
INTRODUCTION Since many actual control systems such asthose in structural engineering are subjected torandom excitations and the system states are esti-mated from measurements with random noise,stochastic optimal control of partially observablesystems is a research subject of much significance.One basic approach to this problem is to convert itinto the stochastic optimal control of completelyobservable systems using separation theorem(Wonham, 1968; Fleming and Rishel, 1975; Ben-so… 相似文献

This study investigated attitudes towards multiculturalism and their influence on acculturation strategies of both Anglo-Australians and Asian immigrants residing in the city of Brisbane, the third largest city of Australia. Data was obtained via a survey administered to 133 Asian immigrants and 108 Anglo-Australians, a total of 241 respondents. Results revealed discordance in attitudes towards multiculturalism between Asians and Australians, with Asians rating it higher as a benefit and lower as a threat as compared to Australians. While higher ratings on multiculturalism as a threat tended to be positively related to separation strategy, this linear association did not hold true for the minority group (Asians). For Asian respondents, those who perceived a moderate threat in multiculturalism were more likely supporters for separation. Our findings supported the assumption that multiculturalism is viewed as differentially beneficial for minority and majority groups. 相似文献
