Create figures centered on model mechanism, solution process, and core conclusions, avoiding irrelevant decorations. Use a white background with low-saturation colors, maintaining a unified and clean style. Use SimSun for Chinese text and Times New Roman for English and numbers. Ensure axis labels, units, legends, and data labels are complete and clear, with appropriate font size and no overlap. Colors, line styles, and markers should be distinct and distinguishable in black-and-white printing. For flowcharts, ensure arrow directions, decision branches, and hierarchical relationships are accurate. Keep figure titles concise and cite them by number in the main text. Minimize text within figures, keeping only key information. Do not use natureskill. Prioritize vector formats such as PDF and SVG, while also providing high-resolution PNG files. After modification, no need to push.
