试验者为小细胞肺癌患者,于右上臂皮下植入缓释VP-16(又称依托泊苷或鬼臼乙叉苷),按预定时间点采集静脉血并分离出血浆。血浆样品以氯仿萃取,常温下负压挥发至干,然后以流动相溶解,采用反相高效液相色谱法测定。流动相为V(甲醇)∶V(水)=52∶48的溶液,检测波长为UV-228 nm,色谱柱为Lichrosphere C18(250 mmX4.6 mm i.d.,5 μm)。用外标法定量。实验结果表明,该测定方法的检出限为0.02 mg/L,绝对回收率为80.4%,相对回收率为94.7%,日内和日间精密 相似文献

To predict the heat diffusion in a given region over time, it is often necessary to find the numerical solution for heat equation. However, the computational domain of classical numerical methods are limited to flat spacetime. With the techniques of discrete differential calculus, we propose two unconditional stable numerical schemes for simulation heat equation on space manifoldand time. The analysis of their stability and error is accomplished by the use of maximum principle. 相似文献
