怎麼填變量：[科學概念] 填一個英文單詞效果最穩，例如"ATOM""LIGHT""NEURON""ENTROPY"；想做中文版可以試"光""熵"這類一兩個字的詞，並寫明"漢字筆畫由光線折射圖構成"。[黑板 / 藍圖] 選一種底色。示例圖是 2×2 合集：左上藍圖底上用雙螺旋拼成的"DNA"，下方有鹼基配對說明和基因序列；右上黑底白線用六邊形和分子結構拼成"CARBON"，配石墨烯、富勒烯小圖；左下"GRAVITY"字母被彎曲的時空網格拉向一個質素點；右下"ELECTRICITY"由電路符號組成，配歐姆定律、交流波形和電路圖例。

常見問題與調整：

• 字母認不出來：加"字母輪廓優先清晰，結構圖案只作為筆畫的填充"。
• 變成彩色三維分子：重複"只用單色線稿，平面，無陰影"。
• 周邊公式寫錯：只保留標題和一兩個簡單圖例，或把正確公式直接寫進提示詞。
• 想做豎版海報：畫幅改 3:4，單詞豎排或拆成兩行。

適合：科普講座標題頁、理科課件封面、實驗室 / 社團海報；不適合直接當作嚴謹的科學圖解。

Anchor: The word "[SCIENTIFIC CONCEPT (e.g.,  CARBON / DNA / GRAVITY)]" :: where each  letter is constructed from the molecular  structure, atomic bonds, or physical  diagrams associated with that concept ::4  Morphology: DNA — letters formed from  double helix ladder rungs and backbone  curves. CARBON — letters built from  benzene ring hexagons and bond lines.  GRAVITY — letters curve and stretch  as if pulled toward a point mass,  lower strokes elongated by gravitational  lensing. All fully readable ::3  Material Physics: Scientific whiteboard  aesthetic — white chalk or marker on  dark ground. Or blueprint blue with  white diagrammatic linework ::3  Illumination: Flat, even, academic —  as if projected on a lecture screen ::2  Render Stack: Science magazine cover,  university poster, Ted Talk title card ::1  Negative: [photorealistic molecular  renders, 3D shading, color-coded  atoms in standard CPK colors,  realistic laboratory imagery] :: -1
