定律 (通过大量事实归纳而成的结论, 是客观规律的表达形式之一) law 能量守衡定律 law of the conservation of energy; 万有引力定律 the law of universal gravitation; 物质不灭定律 law of conservation [indestructibility] of matter; 物质能量守衡定律 matter-energy equivalence
Although the quantum laws are thought to be valid for objects of all sizes ? from elementary particles to the universe as a whole ? we do not usually see matter waves or any other quantum behavior in our everyday world 虽然量子定律应该适用于各种不同大小的物体(从基本粒子到整个宇宙) ,但在日常生活里,我们通常看不到物质波或是其他的量子现象。
