摘　　要：研究了磁场对发生在液-液两相界面上的酶促反应的影响.4℃时磁化酶溶液,短时间内酶活性显著提高,0.1T的磁场作用1h可使酶活力提高76.1%,随着作用时间的增长,酶活性逐渐降低.pH值、温度均对酶的磁效应有明显的影响;酶的磁效应存在着滞后效应;磁化水也可明显提高酶的催化活性,经0.485T的磁场作用的水可使酶活性提高将近1倍.The effect of a magnetic field on enzyme reaction on the phase boundary of liquid is studied. The observed effect is in connection with temperature and exposed time. The delaying effect of the magnetic field is also observed. Magnetized water significantly increases the catalytic activity of lipase.
