全等转变

Chemical analysis showed that the fresh basalts and corestones slightly changed in composition except that variations in Fe(superscript 2+) to Fe(superscript 3+) are most noticeable. In the course of corestones changing to saprolite elements of Si, Ca, Na and Mg, the ratio of SiO2/Al2O3 decreased gradually, while the elements of Fe, Al and the values of LOI and CIA significantly increased.

化学全分析结果表明新鲜玄武岩与核心石在除Fe外，其它组分无明显的改变；核心石在转变为腐岩过程中Si、Ca、Na、Mg等元素逐渐流失，Fe、Al等逐渐富集，同时烧失量LOI和化学蚀变指数CIA显著增加，硅铝比逐渐减少。

Completely different crystal structures and morphology were shown in the meltdrawn films of two kinds of tacticity of sPP. A continuous conformational transform from the 〓 into the of sPP was induced by further stretching. While the zigzag conformation can retransform back to helical 〓 one after annealing above 80℃, the mechanism of conformation transform has been introduced.
