图即为不同乙基纤维素添加量所得油相乳化后所得乳液的光学显微镜照片。从图中可知，随着乙基纤维素用量的增加，所得油相溶液乳化后，分散相尺寸也有增大的趋势，从而进一步证实了油相溶液粘度对所得乳液分散相尺寸的影响，即油相溶液粘度越大，则所得乳液分散相粒径越大。

The figure is an optical microscope image of the emulsion after oil phase emulsification with different amounts of ethyl cellulose.  It can be seen from the figure that with the increase of the amount of ethyl cellulose, the size of the dispersed phase also increases after the emulsification of the oil phase solution, which further confirms the influence of the viscosity of the oil phase solution on the size of the dispersed phase of the emulsion, that is, the larger the viscosity of the oil phase solution, the larger the particle size of the dispersed phase of the emulsion.
