Where more than one metal chelating group is used the metal chelating groups may be the same or different.

如果有一个以上的金属螯合组用于金属螯合组可以在相同或不同的。

In addition, these compounds have no obviously chelating ability in the Fe2+ assay.

然而在螯合亚铁离子的试验中发现它们的螯合能力均不显著。

After hypodermic inoculation of the Non Occluded Shrimp Virus obtained from diseased prawns , crawfishes suffered and died.

用从对虾病料提取的无包埋体对虾病毒人工接种淡水的克氏原螯虾，螯虾发病死亡。

After twenty-one days, they were challenged by white spot syndrome virus. The mortalities of crawfishes after challenged with WSSV of the same dilutions were negatively correlated with the the dose of Ig-Guard, that is, along with the increase of the dose of Ig-Guard, their mortalities were decline; The LD50 of the immune group was higher than the control group, further more, along with the increase of the dose of Ig-Guard, the effectes were obvious.

注射相同稀释浓度的螯虾，其死亡率与添加Ig-Guard的剂量呈负相关，即添加Ig-Guard剂量越高，其死亡率越低；免疫组螯虾的半数致死剂量(LD50)高于对照组的半数致死剂量，而且其效果随着免疫剂量的增加而越来越明显。

Therefore, pretreatment of raw flax was performed with selected chelating agents such as ethylene diamine tetraacetic acid, sodium tripolyphosphate, oxalic acid and ammonium oxalate.

选用EDTA、多聚磷酸钠、草酸和草酸铵等螯合剂对亚麻原麻进行了预处理，结果表明：EDTA、草酸、多聚磷酸钠的处理效果均不理想，改变浓度、温度等条件，韧皮与麻秆并没有分离；而草酸铵是比较有效的螯合剂，用5 g/L的草酸铵在62℃处理亚麻原麻5 h后，韧皮与麻秆能够完全分离。

This project not only illuminates involvement of iron in the etiology of PD, but also gives some clues for the cure of Parkinson''s disease by studying the effect of iron chelators. This may be helpful for us to fully understand PD.

本研究为脑内高铁参与PD的病因学提供了新的实验依据，而且通过应用螯合脑内特殊部位过量铁并改善症状的铁螯合剂，为神经退行性疾病的防治开拓一条新的研究领域和可能的干预措施。

ALA is the only one of the common chelators which crosses the blood-brain-barrier, so you need to use ALA at some point in order to clear mercury from the brain.

ALA 是常用螯合剂中唯一能够穿越血－脑屏障的一种螯合剂。所以你应该在一定阶段使用 ALA 以清除大脑中的汞。

Moreover, the result about the inhibitory effect on ryanodine binding of concentrated chelators indicates that using proper concentrations of chelators is essential in ryanodine binding assays.

此外，高浓度螯合剂抑制ryanodine结合的结果还表明，在ryanodine结合实验中，使用的螯合剂浓度不能过高。

Using the on-line sequence similarity searching tool Fasta3 on internet web,many neuropeptides from crustacean CHH family of high similarity with thesededuced amino acid sequences from cDNA of eyestalks from these four kinds animalswere found.

在所有的相似序列中，分别由中国对虾、中华绒螯蟹、鹰爪虾和蓝对虾的特异性cDNA片段推定的氨基酸序列与蜕皮抑制激素的相似度最高，这一结果提示分别由中国对虾、中华绒螯蟹、鹰爪虾和蓝对虾的眼柄特异性cDNA片段推定的氨基酸序列可能是这四种甲壳动物的MIH片段。

Do not gum up the work by telling mother what we are going to do .

别告诉母亲我们要干的事，那会把事情搞糟的。

In recent years, application of the partial prestressed concrete beam s is developed.

近年来，随着部分预应力砼梁应用的推广，发现我国规范所采用的名义拉应力法的计算结果不稳定。
