Procedure— Where the individual monograph specifies that the water content is to be determined by Method Ib, transfer 35 to 40 mL of methanol or other suitable solvent to the titration vessel, and titrate with the Reagent to the electrometric or visual endpoint.

规程---当各论规定使用方法Ib测定水的含量时，转移35~40ml的甲醇或者其他合适的溶剂至滴定容器中，用卡尔试剂滴定，以永停法或视觉观察终点。

Procedure— Unless otherwise specified, transfer 35 to 40 mL of methanol or other suitable solvent to the titration vessel, and titrate with the Reagent to the electrometric or visual endpoint to consume any moisture that may be present.

操作---除另有规定外，转移35~40ml的甲醇或其他合适的溶剂至滴定容器中，以永停法或视觉指示终点，用卡尔试剂滴定可能存在的水汽（所消耗体积忽略不计，因为不会代入到公式计算），快速加入测试样本，混匀，然后再次用卡尔试剂滴定到终点。

The selfmade microtitration was convenient and accurate, could be used to determining the contents of chlorphenamine maleate.

自制微型滴定装置具有较好的操作性能和精密度，符合滴定分析法的要求，可用于测定马来酸氯苯那敏的含量。

The author is in half minim of GB/T5009.44-2003 undertakes reforming on azotic law foundation surely, use triumphant family name to decide azotic appearance to undertake distillation titrate, undertook reclaiming at the same time of rate, precision determine and determine with GB law the contrast of the result.

笔者在GB/T5009.44-2003半微量定氮法基础上进行改良，利用凯氏定氮仪进行蒸馏滴定，并同时进行了回收率、精密度的测定以及和国标法测定结果的对比。

The either titrate in titration process is nodded, the affiliation of the chroma of the Ag+ in solution and titration agent bulk can determine by the potential of two electrode the value is obtained at the same time, thereby applicable is multivariate and corrective the content that the law gets ion of the avery kind of in mixing haloid ion by corresponding titration curve.

在滴定过程中的任一滴定点，溶液中Ag+的浓度和滴定剂的加入体积可由两个电极的电位测定值同时获得，从而可应用多元校正法由相应的滴定曲线求得混合卤素离子中每一种离子的含量。

Results: The contents determined with microtitration were 98.73% and that of regular titration was 98.71%.

通过微型滴定和常规滴定对比，高氯酸冰醋酸（0.1 mol/L）为滴定液，结晶紫为指示剂，用非水滴定法测定马来酸氯苯那敏的含量。

Methods: Perchloric acid and glacial acetic acid were volumetric solution. Crystal violet was indicator. Results: The contents determined with microtitration were 98.73% and that of regular titration was 98.71%.

The titrant is a mixture of EDTA and sodium fluoride, both mercury film electrode and fluorinion selective electrode are inserted in the titration solution. In a process of titration, both the added volume of titrant and the concentration of mercury ion at each titration point can be obtained simultaneously from the potentials of two electrodes, and then the concentration of each component in the alloy can be obtained from the titration curves by multivariate calibration.

用ED-TA与氟化钠的混合溶液作为滴定剂，被滴定液中同时插入了汞膜电极和氟离子选择电极，在滴定过程中的任一滴定点，溶液中汞离子的浓度和滴定剂的加入体积可由两个电极的电位测定值同时获得，从而可应用多元校正法由相应的滴定曲线求得混合金属中每一种组分的含量。

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。
