tetragonal

基本解释

The mineral chalcopyrite usually is found in compact masses or in mixtures with various other mineral as opaque, brass-yellow, tetragonal crystals.
黄铜矿通常以不透明的黄铜色的四角形结晶的方式在紧密物质或和其他各种矿物质混合体中被发现。
It is possible that oxygen vacancies formed in the surface region in the absence of oxygen can prevent the transformation from the tetragonal to the monoclinic phase.
这可能是由于在缺氧条件下样品表面形成了一种具有氧空位的扭曲结构，这种结构可以阻止四方相到单斜相的转变。
These disadvantages cannot be overcome by addition of tetragonal zirconia resulting in phase transition toughening, because of the low elastic module of the ceramic artificial bone materials.
由于生物陶瓷材料的弹性模量较小，很难采用添加氧化锆引起的相变增韧来解决上述缺点。

relating or belonging to the crystal system characterized by three mutually perpendicular axes of which only two are equal (See also dimetric)

四方相
The influence mechanism of doping rare earth oxides on the thermal physical property of YSZ is that co-doping with Gd2O3 and Yb2O3 results in lattice distortion and content variation of monoclinic phase（M）,tetragonal phase（T） and cubic phase（C） in YSZ.
稀土氧化物掺杂对YSZ陶瓷材料热物理性能的影响机制为:掺杂Gd2O3和Yb2O3导致YSZ中单斜相（M）、四方相（T）和立方相（C）含量发生变化,同时YSZ晶格发生畸变。
