The 2D entropy threshold method was used to segment the waxcrystal images.
首先,采用分块二维熵图像阈值法进行蜡晶图像的自动阈值分割;

PPD makes the critical radius and the potential barrier of nucleation of waxcrystal increase, and makes the separation of wax from waxy oil difficult.
降凝剂提高了蜡晶析出的临界半径,增大了成核位垒,使蜡晶析出困难。

The influence of pour point depressant on the shape and electric properties of waxcrystal was studied by micro-electrophoresis meter and polarizing microscope.
