通过调整仪器的硬件参数曲率值和斜率值,归纳出它们对DSC基线形状的影响规律;继而分析曲率值和斜率值对仪器稳定性的影响。实验结果表明,为了保证样品信号的准确性,DSC基线的优化应遵循"仪器稳定性优先、兼顾基线形状"的原则... 通过调整仪器的硬件参数曲率值和斜率值,归纳出它们对DSC基线形状的影响规律;继而分析曲率值和斜率值对仪器稳定性的影响。实验结果表明,为了保证样品信号的准确性,DSC基线的优化应遵循"仪器稳定性优先、兼顾基线形状"的原则,利用软件扣除基线功能,消除基线非直线形状的影响。 展开更多

Different from the conventional synthesis methods and substrates, we designed a brand new method for synthesizing amides with platinum nanowires as catalysts and tert-butylhydroperoxide(TBHP) as the oxidant. Influence... Different from the conventional synthesis methods and substrates, we designed a brand new method for synthesizing amides with platinum nanowires as catalysts and tert-butylhydroperoxide(TBHP) as the oxidant. Influence of factors, such as the catalyst, solvents, and the reaction temperature, were studied to determine the optimal reaction conditions. In addition, we explored the substrate generality and observed excellent yields. 展开更多
