The growth of com crystals at stearic acid monolayer was regular and both end of the crystals became sharp angles because stearic acid molecular has negative group . the crystals beneath dppc monolayers were oriented with the elongated hexagonal ( 101 ) face paralleled to the plane of the monolayer and smaller than those from bulk solution ) 01 )晶面与膜平面平行生长，而且，在相同结晶时间里，磷脂dppc单分子膜诱导下的com晶体的粒径比本体溶液中的com晶体粒径要大。
