另一方面，对大量文献材料中报道的有关等电聚焦中pH梯度不稳定性的实验，采用MCRB理论衍生得到的判别式Rr进行分析和预测，并与实际的结果相对照。

Under the optimized conditions, the relative fluorescence intensity decreased linearly with the copper ions concentration in the range from 2 to 200μg·L~(-1) and the detection limit could reach 0.29μg·L~(-1). Based on the charge-transfer quenching mechanism, the copper ions bounding onto the surface of qdots could absorb electrons from valance band, which results in the quenching of fluorescence.

用电荷转移机制解释了量子点荧光猝灭的原因，主要是由于价带电子激发到导带以后被表面结合的Cu~(2+)离子捕获而产生的结果，在此基础上，用光解实验进行了进一步的验证。

The composition cesium and/or rubidium ions provide site directing ions for targeted in vivo delivery.

本制剂的铯即或铷离子能为目标的活体内传输提供癌瘤部位引导离子。

The scintillation CsI was also calibrated with protons of 15, 20, 23MeV. The average energy calibration is 1. 047MeV per channel. Energy calibration for heavy ions was completed with multiplication factor 1/12. 75. The energy calibration is around 1. 1MeV per channel for oxygen ion and iron ions when energy deposition is less than 50MeV in each detector.

对铁离子而言，铁离子的四个能量点在ΔE〓探测器中的能量均超过50MeV，能量信号放大电路此时已进入饱和状态，当铁束能量为120MeV时，离子进入到ΔE〓探测器中，此时在ΔE〓中能量沉积低于50MeV，没有达到电子学系统的饱和值，能量刻度每道为1.1MeV／道，这些与氧离子的标定结果是一致的，饱和只是对于低能重粒子会出现这种情况，对于中高能重离子这种现象就会消失。

We all know that if there are metal ions stable existed in protein, the metal ions should form chelate.

我们知道若是要让金属离子稳定的存在在蛋白质中，必须产生螯合物。

Calcium citrate is also used as a water softener because the citrate ions can chelate unwanted metal ions.

柠檬酸钙也可以用来作为水柔软剂，因为柠檬酸离子螯合有害金属离子。

The results show that quartz cannot react with oleic irons at pH=8-10, because it is difficult to combine with metallic irons. On the contrary, clinochlore can adsorb with oleic ions because there are enough active metallic positive ions between the minerals layers which can combine with clinochlore. The clinochlore can be hydrophobic, and so the separation can be realized finally. At pH=9, the clinochlore removal rate is the maximum, the purity of SiO2 is 99.86%, and the recovery of SiO2 is 35%.

结果表明：在pH为8~10的碱性溶液中，粉石英难与金属阳离子缔合，所以，不与油酸根离子结合；而斜绿泥石解离后层间存在活性金属阳离子，可与油酸根离子发生化学吸附产生疏水作用，因而使用反浮选的方法能有效地实现二者的分离：当pH为9时，斜绿泥石的去除率最高，粉石英的纯度达99.86%，回收率为35%。

The author also changes theproportion of Fe~(3+)、Cu~(2+) in total ions to study the complementariness of Fe~(3+)、Cu~(2+) in thesystem and proves that the replacement of the single catalytic ions with the complicatedSystem Fe~(3+)/Cu~(2+)/H_2O_2 has a good ability of the ability of counter assault against thechanges of pH value.

通过改变Fe~(3+)、Cu~(2+)在总离子中的不同比例，研究了Fe~(3+)、Cu~(2+)在体系中的相互补充、相互促进的作用，证明了用Fe~(3+)／Cu~(3+)／H_2O_2复合体系代替单一的催化离子能有效的对pH的变化起到很好的抗冲击的作用。

The effect of reaction time, the pharmaceutical dosage, pH value, reaction temperature and ions concomitance on removal cuprum, zincum and nickel ions was studied.

方法］研究反应时间、药剂用量、pH值、反应温度以及离子共存对其效果的影响。

In the titration experiment of NMR and IR spectroscopy, we can understand how sensors binding with metal ions: the two carbonyl group and crown ether group cooperated in binding with metal ions. Furthermore, by altering the "oxygen" atoms of crown ether to "sulfur", we can change the binding affinity to the soft metal: cupper. It shows 60-fold enhancement of fluorescence.

在化合物2中，我们引进了硫原子在冠状醚中，则应对电子密度较低之金属有较好的结合能力，实验结果显示了此分子对铜离子有相当好的选择性和结合能力，萤光增加可达60倍；同时由红外光吸收光谱和核磁共振光谱滴定实验可确知，香豆素衍生物上的两个羰基对金属离子的选择性及结合上扮演相当重要的角色。
