Results There was a statistically significant difference of microleakage between the Gallium Alloy and GK High Copper Amalgam group after 28 days 'immersion in 1% Methylene Blue solution ( P < 0.01). 结果镓合金组根尖充填后28天时的微渗漏情况明显优于GK高铜银汞合金组,差异有显著性意义(P<0.01)。
Electrochemical behavior of cefazolin sodium at hanging copper amalgam dropping microelectrode and its trace determination 头孢唑啉钠在悬铜汞齐微电极上的电化学行为及其痕量测定
To solve this problem, the traditional method is to add a certain amount of metal mercury which can react with the copper coating in the anode lid to produce amalgam and lower hydrogen evolution corrosion, so as to restrain the production of hydrogen. 为了解决该问题,传统的方法是在负极锌粉或锌膏中添加一定量的金属汞,汞与负极盖内壁的铜镀层反应生成汞齐,降低析氢腐蚀,抑制氢气的产生。
Zinc, cadmium, lead, copper and bismuth form an alloy of similarly amalgam in the process of concentration, with a good stripping peak. 锌、镉、铅、铜在富集中和铋形成类似于汞齐的合金,溶出峰良好。
