摘要：采用高效液相色谱法检测变压器油中糠醛所用糠醛标准溶液稀释剂对分析结果有显著影响。为筛选糠醛标准溶液稀释剂,对4种稀释剂（新基础油（未处理）、45号新变压器油、25号新变压器油、纯甲醇）进行试验。试验结果表明,45号新变压器油作为糠醛标准稀释剂对糠醛分析结果影响最小,测定结果准确性高,重复性好,并且在0.00~10.00 mg/L范围内线性良好。以45号新变压器油为糠醛标准溶液稀释剂,采用高效液相色谱法对近30台变压器油样中的糠醛含量进行分析,结果完全符合《油浸式变压器绝缘老化判断导则》的规定要求。

摘要：目的提出一种混合设计新序列(TTRR、RRTT、RTTR、TRRT)来探究其在药物可互换性方面的适用情况。方法基于Chow等提出的药物可交换标准(SCDI)为评价标准,考虑药物个体间变异,探索新序列在药物可互换性中的适用情况,并和常用序列(TRTR、RTRT)进行比较。结果通过计算机对不同情境的模拟,发现新序列大体上呈现一致趋势并且在药物可互换关键部分σWR、σD等变动时,本研究提出的新序列表现出比常用序列更加敏感的特点。结论虽然新序列比常用序列在药物可互换中对于变异变动时更加敏感,但多出的两个序贯使得其在样本量方面表现欠佳。
