By researching the original analysis method for CaF2 in fluorspar,this paper discovered its shortcomings,determined three main factors for causing CaF2 analysis results to be lower slightly:determination of total Ca contents,determination of CaCO3 as well as calibrating of EDTA standard titration solution.

通过对萤石中 CaF2的原分析方法的研究，找出其中的不足，确定了导致 CaF2分析结果偏低的三个主要因素：Ca的总量的测定、CaCO3的测定以及EDTA标准滴定液的标定，结合国家标准分析方法，对我们正在使用的分析方法进行改进，以解决这些问题。

"So now I need to know what it takes to balance it back to neutral with my titration fluid," he says.

"所以现在我需要知道如何才能平衡回来我滴定液中立，"他说。

The titration of the sodium hydrogen carbonate content in medicinal sodium bicarbonate tablet was compared with microburette under syringe control made on our own with conventional burette.

"So now I need to know what it takes to balance it back to neutral with my titration fluid," he says.

&所以现在我需要知道如何才能平衡回来我滴定液中立，&他说。

After the equivalence point, there is excess titrant present.

等当点之后，有多余的滴定液出现。

When the titrant is reduced, it turns colourless.

当滴定液被还原时，它就变成无色。

For example, an oxidation-reduction titration using potassium permanganate (pink/purple) as the titrant does not require an indicator.

例如，一种以高锰酸钾为滴定液的氧化－还原滴定就不需要指示剂。

The direct amperometric titration of amines with sodium tetraphenylborate solution based upon anodic depolarization at a dropping mercury electrode by the use of excess TPB titrant, was systematically investigated.

本文研究了用pH8的四苯硼酸钠水溶液对胺类的直接电流滴定法。滴汞为阳极，饱和甘汞为阴极，以3％琼脂的饱和NaCl溶液为盐桥组成电解池。适宜的滴定条件是：外加电压+0.18伏；底液为pH 2-3的HAc-NaAc介质，而以1％HAc更为方便；滴定体积为10-20毫升。
