底心正交 meaning in English
end-centered orthorhombic
Examples
- The conclusions are reported as following : the structure change of triuranium octaoxide ( u3o8 ) was studied by xrd at ambient atmosphere at temperature form 25 to 850 . there are two kind of phases of u3o8 in the temperature range studied , and the transformation temperature is about 300 . the low temperature phase is orthorhombic with space group amm2 , and it change to another phase with better symmetry around 300
主要的研究结果如下：对u _ 3o _ 8的相变和结构随温度的变化进行的分析研究结果显示：在300附近u _ 3o _ 8发生了相变，由底心正交结构(空间群为amm2 )的低温相转变为简单六方结构(空间群为p - 62m )的高温相。
