Since tests prescribed in monographs have been developed using thioacetamide reagent R, if sodium sulphide solution R1 is used instead, it is necessary to include also for methods A and B a monitor solution, prepared from the quantity of the substance to be examined prescribed for the test, to which has been added the volume of lead standard solution prescribed for preparation of the reference solution.

由于专论中的试验描述使用硫代乙酰胺试液，如果用硫化钠溶液R1(0.1ml)代替，方法A和方法B的控制溶液应按照试验中待测供试品要求的数量加入到方法规定体积的标准铅对照溶液中。

各论中规定使用硫代乙酰胺试液，因此若要改用硫化钠溶液，无论是方法A还是方法B都应制备控制溶液。控制溶液的制法：取规定量的供试品，加入制备对照溶液所需的铅标准溶液。monograph可以翻译成&各论&，即具体品种的药典标准。

The methods described below require the use of thioacetamide reagent R. As an alternative, sodium sulphide solution R1 (0.1 ml) is usually suitable.

从分析铍青铜材料的特殊性入手，针对性地采取有效的前处理工艺措施，以硫代硫酸盐镀银取代传统的有毒的氰化镀银，分析了银镀层变色的原因并提出了相应的抗变色处理措施。

Objection:To investigate the significance of contrast-enhanced ultrasound in quantitative diagnosis of liver cirrhosis. Methods:Rabbits models with liver cirrhosis of different stages were successfully made by feeding them with thioacetamide solution. And a self-comparison method was adopted in the trial. The hepatic artery to vein transit time was taken as the parameter for evaluation.

30只实验兔以1.20 g／L的硫代乙酰胺水溶液作为惟一饮用水的方法建立不同阶段的肝硬化模型，应用Bracco公司生产的声诺维作为造影剂，并用自身前后对照的方法，在肝硬化模型建立前后测量肝静脉内造影剂出现的时间及肝动脉内造影剂出现的时间，两者相减得到肝动静脉渡越时间，比较肝硬化前后数值间的差异。

The intermediate 5-amino-1H-pyrazole-4-carboxylic acid ethyl ester prepared in the first part underwent successively hydrazinolysis, condensations with ketene dithioacetals and alkylations to give rise to the dipyrazolyhnethanes.

从第一部分中的中间体5-氨基-1H-吡唑-4-羧酸乙酯开始，经过肼解、与乙烯酮二硫代缩醛的缩合反应和烷基化反应，合成了二吡唑基甲酮类化合物。

After the digestion of the samples of the effort of the mixed acid, in the condition of pH=2~2.8, the lead in the sample solution and the added pyrrolidine a two-ammonium thiosulfate can come into being a metal complex. With A methyl isobutyl ketone extraction, the lead complexes can be divided from the water phase.

采用混合酸对样品进行消化处理后，在pH2~2.8时，样品溶液中铅与加入的吡咯烷二硫代氨基甲酸铵形成金属络合物，用甲基异丁基甲酮萃取，使铅络合物与水相分开。

In this paper, the ammonium pyrrolidinyldithiocarboxylate- methyl isobutyl ketone chelated-extract system was used. APDC chelated with Pb2＋ in solution, and then extracted into organic phase with MIBK. The cyclic voltammetric behavior of Pb-APDC complex at the liquid/liquid interfaces has been studied with classic three-electrode.
