Phase transition of lipid molecules between liquid and crystalline states in the vesicle membrane has a non-isothermal pattern; it is spread in some temperature range, which depends on the vesicle size. With a change of phase transition the area which falls within a lipid molecule is changed. As a result elastic tensions appear in the membrane. They may account for the non-isothermal pattern of phase transition. The number of molecules in each state is calculated in relation to temperature, and the temperature range is calculated within which the phase transition is realized. The smaller is the vesicle radius, the higher is the temperature range value. Temperature relationship of the membrane heat capacity at non-isothermal phase transition is calculated. The obtained results well agree with the number of experimental data.
囊泡膜中脂质分子在液态和晶态之间的相变具有非等温模式；它在一定温度范围内展开，该温度范围取决于囊泡大小。随着相变的变化，脂质分子所占的面积会发生改变。结果，膜中出现弹性张力。它们可能是相变非等温模式的原因。计算了每种状态下分子数量与温度的关系，并计算了实现相变的温度范围。囊泡半径越小，温度范围值越高。计算了非等温相变时膜热容量与温度的关系。所得结果与大量实验数据吻合良好。
