斜方晶系 - 百度百科
斜方晶系（Orthorhombic System）三条结晶轴彼此相互垂直但长度皆不同，外形为长方的柱状或板状结构。 托帕石（Topaz）的柱状结晶是此晶系典型的例子。 [1] 这一晶系的对称特点是无高次对称轴，但二次对称轴和对称面的总数不小于三个。 晶体即以这三个相互垂直的二次轴或对称面的法线作结晶轴。 轴角α=β=γ=90°但轴单位a≠b≠c。 故斜方晶系具有更强的非均质性。 平行c轴、b轴和a轴的折射率均不相同，即具有三个主折射率。 属于这个晶系的常见晶形有斜方柱、斜 …
Orthorhombic crystal system - Wikipedia
In crystallography, the orthorhombic crystal system is one of the 7 crystal systems. Orthorhombic lattices result from stretching a cubic lattice along two of its orthogonal pairs by two different factors, resulting in a rectangular prism with a rectangular base (a by b) and height (c), such that a, b, and c are distinct.
晶系 - 百度百科
晶体根据其在晶体理想外形或综合宏观 物理性质 中呈现的特征对称元素，可划分为立方、六方、三方、四方、正交、 单斜 、三斜等7类，是为7个晶系，分属于3个不同的 晶族。 高级晶族中只有一个 立方晶系；中级晶族中有六方、四方和三方三个晶系；低级晶族中有正交、单斜和三斜三个晶系。 特征对称元素亦能确认与每种晶系对应 晶胞 的形状或 晶胞参数 相关性的特征。 各晶系的晶胞类型一般用晶胞参数a、b、c和α、β、γ表示。 其中a、b和c是晶胞三个边的长度，习惯上叫 …

Donald B Peck - Crystallography: The Orthorhombic System
The orthorhombic is a three axis system with the three axes mutually at 90o angles to each other and with the b axis taken as left to right and the longest, the c axis as being vertical and the shortest, and with the a axis intermediate in length and front to back.
Orthorhombic System - Explanation, Examples and Solved …
The orthorhombic is a three-axis System each of which are mutually at 90° angles and x axis is vertical and the shortest with the a axis which is intermediate in length and is from front to back and the B axis is taken as left to right with the longest. The orthorhombic unit cell has its own set of unique characteristics.
Orthorhombic Crystal System I - metafysica.nl
The Orthorhombic System contains Forms that can be referred to three non-equivalent (i.e. having unequal lengths) crystallographic axes holding angles of 90 0 between them. One uses to orient the orthorhombic axial system such that one axis is vertical which is then called the c axis.
Orthorhombic crystal system | Earth Sciences Museum
In this system there are three axes, all of which meet at 90 degrees to each other. However, all the axes are a different length. This crystal system has the following forms: Prism: Prisms have a set of faces that run parallel to an axis of a crystal, yet never converge with it.
