【摘要】 实验改进后,减少了清洗、烘干及冷却样品管的实验操作环节;装样长度可比原来或多或少(9.5~10.5 cm);一种试样固定用一支样品管进行实验.实验结果与理论值基本相符,比改进前误差小.改进后可大大地缩短实验时间,减少实验用品和降低实验费用,且减少了对实验室、环境的影响.在实验教学中反复应用,效果较好,值得推广.更多还原

【Abstract】 The conventional Gouy method was improved by which procedures as rinsing,drying and cooling of the samples were omitted as long as each tube was fixed to one sample.The loaded sample length was adjustable to 9.5-10.5 cm instead of a fixed one.The experimental result was in agreement with theoretical value by smaller error.The improved method reduces agent dosage as well as experimental time and cost.A less impact on lab environment is also achieved.Practical application exhibits favorable effects and is worth recommendation.更多还原
