ECEC

The experiments show that not only the oxidation of BV is promoted, the reaction mechanism is also changed from a ECEC to a ECCECC process by the introduction of water into DMF.

实验中发现，在有机溶剂DMF中引入水不但促进了BV氧化反应的进行，而且还使BV的氧化反应由在DMF中的ECEC历程转变为ECCECC反应过程。

When the concentration of exogenous La 3+ was higher than 300 mg/ kg, base saturation percentage ( BSP) and effective cations exchange capacity ( ECEC) decreased significantly, exchangeable acidity and exchangeable aluminum, however, increased significantly compared with the control.

当外源镧浓度大于300mg/kg时，土壤盐基饱和度与有效阳离子交换量显著降低，而交换性酸和交换性铝显著增加。

The result of CFA shows that there are three life style factors among ECEC students, including romance and caring style, self-decided and ambition style, social and fashion style.

验证性因素分析结果显示幼保系学生的生活风格包含浪漫关怀、自主进取、社交时尚等型。
