Manganese oxides supported on SBA-15 Mn(subscript xO/SBA-15 were prepared by incipient wetness impregnation of SBA-15 with furfuryl alcohol solution of manganese acetylacetonate or manganese nitrate followed by removal of the carbon resulted from carbonized FA.

采用溶液浸渍法将乙酰丙酮锰或硝酸锰的糠醇溶液分别灌注到SBA-15的孔道内，一定条件下将糠醇碳化后再将碳烧除，即可得到高度分散的MnO/SBA-15复合催化剂。

In these chloroplasts carbon dioxide combines with phosphoenolpyruvate to form oxaloacetic acid, which is transported to the bundle sheath cells, where the carbon dioxide is released, then fixed by the enzyme ribulose bisphosphate carboxylase to form glycerate 3-phosphate, the first step in the Calvin cycle.

在叶肉细胞的叶绿体中二氧化碳与磷酸烯醇丙酮酸结合形成草酰乙酸，后被运到邻近的维管束鞘细胞，在那里二氧化碳被释放，后被核酮糖二磷酸羧化酶固定形成3－磷酸甘油酸，这是卡尔文的循环第一步。
