A two-dimensional liquid (2D liquid) is a collection of objects constrained to move in a planar or other two-dimensional space in a liquid state. == Relations between 2D and 3D liquids == The movement of the particles in a 2D liquid is similar to 3D, but with limited degrees of freedom. E.g. rotational motion can be limited to rotation about only one axis, in contrast to a 3D liquid where rotation of molecules about two or three axis would be possible. The same is true for the translational motion. The particles in 2D liquids can move in a 2D plain, whereas the particles is a 3D liquid can move in three directions inside the 3D volume. Vibrational motion is in most cases not constrained in comparison to 3D. The relations with other states of aggregation (see below) are also analogously in 2D and 3D. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Two-dimensional liquid」の詳細全文を読む スポンサード リンク
