The evaporation of some oils and their emulsifies was modeled with pan evaporation method , and the characteristics of the evaporation in different states was inspected . the equations of evaporation rate and the factors of inhibitory action of emulsification on evaporation have been obtained . the dynamics mechanism of emulsification has been discussed based on the observation and analysis of the characteristics of oil and water motion 本文主要是从目前研究的薄弱环节作为研究突破口，用浅盘蒸发法对原油及其乳化物的蒸发进行模拟，考察不同原油在不同阶段和乳化状态下的蒸发特征，得出蒸发速率方程及乳化对蒸发抑制作用因子；观测和分析油水运动规律，分析乳化动力学过程；以组成和状态是决定风化特征的主要因素和联系各风化过程的纽带这一思想为基础建立溢油风化预测模型。
