At the same time,a tension stress is applied on theγ′phase interfaces along the direction parallel to the stress axis,which results in the lattice expansion ofγ′phase to trap the Al,Ta atoms with the bigger radius.This brings out the accumulation of the solute atoms to form the N-type rafted structure.Al,Ta atoms with bigger radius diffuse to the {100} plane to form the linked bond of the heterogeneous atoms and the stable stacking mode,this is a main reason of promoting the transformation ofγ′phase into the N-type rafted structure.And the change of the strain energy density in different interfaces of the cubical-likeγ′phase is thought to be the driving force of the elements diffusion and theγ′phase directional growth during creep.

拉伸蠕变期间，类立方γ\'相中与施加应力轴垂直的界面受水平切应力，使晶格收缩可排斥较大半径的Al、Ta原子；与应力轴平行的界面受拉伸张应力，使晶格扩张可诱捕较大半径的Al、Ta原子，由此引起的原子偏聚形成γ\'相是自由能降低的过程；其中，较大半径的Al、Ta原子扩散迁移至{100}晶面，形成异类原子结合键及稳定的堆垛方式，是促使γ\'相形成N-型筏状结构的主要原因；而γ\'相不同界面的应变能密度变化是元素扩散及γ\'相定向粗化的驱动力。

Characterization of cotton fiber using solid-state ~(13)C-CP/MAS NMR spectroscopy shows that the crystallinity after MHT is lower than the original sample,but the cotton after MHT has a higher lateral orientation index,which has a good definition in C2,3,5 resonance region.~(13)C-CP/MAS NMR spectroscopy and X-ray diffraction reveal that cellulose I_βis the main cellulose in cotton,and microwave change the allomorphs content.

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。
