用质膜钙通道阻断剂异博定、钙通道Ca〓竞争性抑制剂以及Ca〓专一性螯合剂与乙烯一起处理绿熟期番茄果实和乳白期草莓果实，均可抑制乙烯诱导番茄和草莓的乙烯生成、番茄PG活性的提高、番茄红素含量的增加和细胞壁可溶性蛋白含量的增加以及草莓可溶性蛋白的分解，表明阻断质膜Ca〓通道或螯合胞外Ca〓以减少胞内Ca〓能抑制乙烯对果实的催熟作用，间接证明乙烯对果实成熟衰老的诱导与胞外Ca〓内流引起的胞质Ca〓浓度的增加密切相关，表明乙烯信号转导可能与钙信使有关，调节胞质Ca〓浓度可调节乙烯对果实的催熟作用。

In pH 5.3-6.8 Britton-Robinson buffer medium, Cefotaxime sodium can react with HgCl2 to form 1:1 anionic chelate, which can further react with basic triphenylmethane dye such as crystal violet, methyl violet, ethyl violet, brilliant green, iodine green, methyl green and malachite green to form ternary ion-association complexes. As a result, the resonance Rayleigh scattering spectrum was enhanced greatly.

实验结果表明在尿素及硝酸铈的混合溶液中分别加入一元羧酸硬脂酸，二元羧酸酒石酸和三元羧酸柠檬酸时，一元羧酸硬脂酸在混合溶液中只起表面活性剂的作用，其产物为斜方晶系的单晶Ce2O(CO3)2.H2O微粉，且表面活性剂硬脂酸的加入使得晶体的晶化程度明显提高；而二元羧酸酒石酸与三元羧酸柠檬酸在均相反应中则起螯合剂的作用，分别与Ce3+形成螯合物酒石酸铈和柠檬酸铈，这些结果的造成是由于其反应机理的不同所导致的。
