crystal system的意思|示意

Crystals are everywhere and can be found in a wide variety of shapes and sizes. Crystals come in many different forms, and each type has its own characteristics and physical properties. Crystals can be classified according to the way they grow, their chemical composition, and the type of unit they are composed of. The seven crystal systems are the basic frameworks that are used to classify crystals according to their geometry and symmetry.

The seven crystal systems are triclinic, monoclinic, orthorhombic, tetragonal, trigonal, hexagonal, and cubic. Each crystal system has its own distinct characteristics that can help you better understand the structure and behavior of the crystal. Each crystal system is described by a set of parameters that describe the symmetry of the crystal. The most important of these parameters are the angle of the axis, the length of the axis, and the angle of the faces.

In the triclinic crystal system, the angles between the axes can be any number; the length and angles of the axes can be any number as well. The faces of the crystal are inclined at all angles, and the symmetry is not perfectly uniform. The monoclinic system has two axes, one of which is inclined at a 90-degree angle to the other; the length and angle of the axes can be any number. The faces of the crystal are not symmetrically arranged and can be any angle.

The orthorhombic crystal system has three axes, each of which is perpendicular to the others. The length of the axes can be any number, and the angles of the faces can be any number as well. In the tetragonal system, the axes are all of equal length and the angles of the faces are all the same. The trigonal system has three axes of equal length and the faces are all at the same angle.

The hexagonal crystal system has six axes of equal length and the faces are all at the same angle. The cubic system has three axes of equal length and the faces are all at the same angle.

Crystals can be classified according to the seven crystal systems because each system describes the symmetry and structure of the crystal. By understanding the crystal systems, you can better understand the behavior and properties of materials that are made from crystals.
