tetragonal

基本解釋

The mineral chalcopyrite usually is found in compact masses or in mixtures with various other mineral as opaque, brass-yellow, tetragonal crystals.
黃銅礦通常以不透明的黃銅色的四角形結晶的方式在緊密物質或和其他各種礦物質混合體中被發(fā)現(xiàn)。
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.
這可能是由于在缺氧條件下樣品表面形成了一種具有氧空位的扭曲結構，這種結構可以阻止四方相到單斜相的轉變。
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彈性模量較小，很難采用添加氧化鋯引起的相變增韌來解決上述缺點。

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.
稀土氧化物摻雜對YSZ陶瓷材料熱物理性能的影響機制為:摻雜Gd2O3和Yb2O3導致YSZ中單斜相（M）、四方相（T）和立方相（C）含量發(fā)生變化,同時YSZ晶格發(fā)生畸變。
