PS can only draw or process pictures (cutting, color matching, etc. ). The pictures in this paper are generally derived from experimental data, microscopic imaging, simulation software, etc. The picture quality comes from the pixels per inch (dpi) of the original picture, which is not helpful. Of course, pixels per inch can be improved by PS, but the image obtained is actually fitted by the software itself, and magazines probably won't use it. The schematic diagram used in this paper can be made by PS. To shoot high-quality images, we must first master PS. In addition, you can refer to the following article /bbs/topic/24 142556? onlyHost= 1
