【摘要】 采用流通池光纤荧光光度法，对固定化乳酸脱氢酶（ＬＤＨ）在静磁场作用下的催化活性进行了探讨．发现在０．０８４～０．２３０Ｔ磁场作用下ＬＤＨ的催化活性明显降低，其降低值随磁场强度增强而增大，且与磁场作用的时间和ｐＨ值有关，而在２５～４０℃范围内，温度则无显著影响。更多还原

【Abstract】 The catalytic activity of immobilized LDH in static magnetic field has been investigated using fiber optical fluorimetry with flow cell.Remarkable decrease of the activity of LDH is observed in a magnetic intensity range of 0.084 to 0.230 T.Asthe magnetic intensity is increasing until up to 0.230 T.the activity of LDH is decreasing until by-17%.This effect is related to magnetization time and pH of subtrate solution, while temperature has no effect in the range of 25-40℃更多还原
