Flavonoids can act as antioxidants, free radical scavengers, and chelators of divalent cations and have a wide range of biological effects .

类黄酮是一组化学结构和性质上不同的多酚化合物，具有抗氧化、自由基清除和二价阳离子螯合作用，具有广泛的生物学功能。

Both of Rice bran and Swida Wilsoniana Oilcake can promoted the the mycelium growth of Pleurotus Ostreatus remarkably when they was added to the basic medium, and the best concentration was 20g/L.

在正常的培养基中米糠和光皮树籽粕能显著促进平菇菌丝的生长（20g/L最佳），同时米糠和光皮树籽粕对Pb2 、Hg2 具有螯合作用，在含Pb2 46.5 mg/L或含Hg2 14mg/L的溶液中，各添加米糠20.0g/L时，前者Pb2 下降到1.08mg/L，后者Hg2 下降到0.026mg/L。

A lowering of toxicity after the composting process may be related to the degradation of organic pollutants (Semple et al., 2001) as well as other processes which can limit their bioavailability, such as sequestration (Alexander, 2000) or/and bound residue.

在堆肥处理后，毒性的减低可与有机污染物(Semple et al。， 2001)的降低以及其他能限制它们生物有效度的处理相关联，例如螯合作用(Alexander， 2000)或者/以及结合残留物。

When EGTA (Ca〓 chelator), Verapmil and LaCl〓(Ca〓 channel blockers) were used to treat tomato fruit at green mature and strawberry fruit at white stage with ethylene, they could reverse ethylene-induced increase in ethylene production in tomato and strawberry, PG activity, lycopene content, soluble protein content in cell wall in tomato and degradation in soluble protein in strawberry, which indicated blocking Ca〓 channel in plasma membrane or chelating Ca〓 can decrease intracellular Ca〓, further inhibite ethylene-induced maturation, ripening and senescence of fruit.

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。

The results of magnesium and calcium ions tolerance test indicated that the modified SPS, synthesized from the above two methods,has good chelation with magnesium and calcium ions for the crablike carboxyl and ester group and increase the reaction weight with magnesium and calcium ions for addition of hydrophilic group.Both of the two modified petroleum sulfonates could produce ultra-low interfacial tension at calcium and magnesium ions concentration lower than 600 mg/L,whereas the general petroleum sulfonates could only produce ultra-low value below 300 mg/L.

耐钙镁离子能力测试结果，以大庆炼化公司两种渣油为原料，采用上述两种合成方法制备的改性石油磺酸钠，由于产物中引入蟹爪状羧酯基，对钙镁离子有较强的螯合作用，同时增加了亲水基，增大了表面活性剂分子与钙镁离子的反应量，因而在600mg/L的钙镁离子溶液中获得10-3级的超低界面张力；而普通石油磺酸钠仅能在300mg/L的钙镁离子溶液中获得超低界面张力。

In the presence of suitable nickel catalyst and without the chelation effect of special designed dithioacetals, simple aliphatic dithioacetals could react with a series of Grignard reagents to give the corresponding olefinic products.

因此在适当的镍触媒存在下，脂肪族硫缩醛在不需要特别的螯合作用下，即可以与一系列的格林那试剂进行烯化反应。

Feeding cottage cheese or yogurt is also considered supplementing calcium, as well as the more obvious forms such as adding bonemeal powder, dicalcium phosphate, Osteoform, etc to the bitch's food.

人们一般认为，脱脂芝士或是酸奶也能补钙，而更直接的方式即在食物中添加骨粉，磷酸氢钙，乐力（含氨基酸螯合钙、氨基酸螯合铜、氨基酸螯合锰等微量元素和维生素D3，属营养类药物）等也有同样的作用。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
