- 1成比例的、按比例的（數學裡「成正比」常說 directly proportional）
If one thing is proportional to another, they stay in a matching relationship of size, amount, or importance. When one grows, the other grows in a steady way. In maths you hear “y is proportional to x,” and also directly proportional (same direction) and inversely proportional (one up, the other down). Outside maths, a proportional share is a fair slice next to the whole. Proportional representation is a voting system where seats match votes. It is a school, news, and official word. Though actually people sometimes stretch it to mean “fair” or “not too much,” which is close but looser than a steady matching relationship.
組成proportion (the relationship of sizes or amounts) + -al (makes an adjective: having to do with).
