    In the physical sciences, a phase is a set of states of a macroscopic physical system that have relatively uniform chemical composition and physical properties (i.e. density, crystal structure, index of refraction, and so forth). The most familiar examples of phases are solids, liquids, and gases. Less familiar phases include: plasmas and quark-gluon plasmas; Bose-Einstein condensates and fermionic condensates; strange matter; liquid crystals; superfluids and supersolids; and the paramagnetic and ferromagnetic phases of magnetic materials.Phases are sometimes called states of matter, but this term can lead to confusion with thermodynamic states. For example, two gases maintained at different pressures are in different thermodynamic states, but the same "state of matter".相: phase 態, 狀態: state相的定義如第一段之英文文字敘述, 恕不贅譯.相有時被稱作物質的狀態(states of matter), 這在討論熱力學的狀態時, 易產生混淆. 譬如: 兩團氣體各自壓力不同, 他們的熱力學狀態不同, 但物質的狀態相同(同為氣態).科學領域的定義, 還是以英文為準.
