二、生化参数测试电极目前,离子选择性电极已用于生物医学领域中进行唾液、血液、尿、汗液和普通牙科、骨科的例行分析。用电极能监测宇航员在失重状态下血和尿中的 K~+、Na~+、Ca~(2+)、Cl~-、pH、Co_2和 O_2的浓度信号,并能把这些信号发回地面。近年来发展的酶膜电极可以分析葡萄糖、青霉素、氨基酸等一类中性 Second, the biochemical parameters of the test electrode At present, the ion selective electrode has been used in the field of biomedical saliva, blood, urine, sweat and general dental, orthopedic routine analysis. Electrodes can be used to monitor the concentration signals of K ~ +, Na ~ +, Ca ~ (2 +), Cl ~ -, pH, Co_2 and O_2 in blood and urine of astronauts under weightlessness and send these signals back ground. In recent years, the development of the enzyme membrane electrode can analyze glucose, penicillin, amino acids and other types of neutral
