Higher PSSS concentration and reaction temperature favored the formation of the meta-stable calcium oxalate dihydrate (COD) crystals and stable calcium oxalate monohydrate (COM), respectively.
较高的PSSS浓度和反应温度分别有利于形成二水草酸钙(COD)和一水草酸钙(COM)。

The ortho-compound formed penta cyclic compound was more stable that the meta-compound formed hexa cyclic compound, so the reaction rate of the ortho-compound is larger.
