Combining the mechanism of oxygen diffusion with the block model in YBCO, the mechanism of the phase transitions can he explained as follows: the phase transition at 400℃ comes directly from O(1) in the rock salt block, and corresponds to the beginning of O-T; the phase transition at 850℃ corresponds to the end of O-T, when O(2) and O(3) of Cu(2)-O plain are rearranged and a few oxygen enter O(1) site of Cu(1)-O plain through O(4) bridge atom, and at last escape from the crystal cell. Thus the phase transition at 850℃ is related with the pervoskite block.

结合YBCO中氧扩散机制和块模型，相变机理解释如下：400℃的相变直接来自于岩盐块，对应于正交－四方转变的起点；850℃相变对应于正交－四方转变的终点，此时Cu(2)-O面中的O(2)和O(3)重排，一些O通过O(4)桥原子进入O(1)位，最后逸出晶胞，因而850℃相变与钙钛矿关系密切。
