In the vacuum dispersing kettle air bubble and solvent vitalization shall be restrained, deaeration of materials shall be accelerated, dispersionefficiency shall be enhanced.
物料在真空容器内分散，减少了气泡和溶剂的挥发，加速了物料脱泡，提高了分散细度。

This means, therefore, that the mill efficiency and degree of dispersion are significant.
因此，这意味着研磨效率和分散度是重要的。

In this paper the study on the dispersion theory, design, manufacture techniques, and efficiency test methods of diffraction gratings were made in a deep way.
