Then the samples were skived into powder, and the powders which can pass through the 0.4*0.4 mm screen were chosen for fluoride concentration determination.

然后把样品削成粉末，将能通过0.4*0.4mm滤网的粉末用来测定氟化物浓度的测定。

The 1-propanol/biuretium flour protein fractionation procedure based on the differential solubility of wheat flour protein in different aqueous solutions of 1-propanol yields three protein fractions, one monomeric in nature and two polymeric fractions corresponding to soluble glutenin, insoluble glutenin. Quantitative of the fraction was made with improved biuret reaction.

丙醇—双缩脲改良测定法用不同浓度的丙醇溶液将小麦面粉蛋白质分离为功能截然不同的单体蛋白、可溶性谷蛋白和不可溶性谷蛋白三部分，然后通过改良双缩脲测定法对不同组分进行定量分析。

The conditions for L-tryptophan determination, such as buffer pH value, buffer concentration and applied voltage were investigated.

应用高效毛细管电泳法对发酵液中L-色氨酸的含量进行了测定，研究了检测波长、缓冲液pH值、缓冲液浓度、分离电压对L-色氨酸测定的影响。

The capillary electrophoretic analysis of inorganic ions in rain water and drinking water was studied.

本文建立了不同水样中无机离子的毛细管电泳分离分析方法，考察了其阴离子和阳离子不同的测定条件；测定了雨水中五种阴离子和饮用水中四种阳离子的浓度

METHODS: Fasting serum levels of IL6, IL8, TNFα were measured in 30 cases of T2DM with insulin resistance and 30 cases of T2DM without insulin resistance and 26 normal control subjects by enzymelinked immunosorbent assay.

采用酶联免疫吸附法测定T2DM伴有IR患者30例和不伴有IR患者30例及正常对照26例的空腹血清白细胞介素6（IL6），白细胞介素8（IL8）及肿瘤坏死因子的浓度，并同时测定空腹血糖、糖化血红蛋白（GHbA1c）及空腹胰岛素水平，分析其与IL6，IL8，TNFα的相关性。

The equivalent point is calculated by thesecond derivative method,which insures a precise detection range of sulfur contentin dye bath from 0.1 to 0.00001 moles/liter.

其测定硫浓度范围在10~(-1)—10~(-5)mol/L 内。实验结果表明，此法操作简便，速度较快，重现性好，回收率达到95%以上，精密度小于5%，是目前测定染液硫含量的一个灵敏方法。

This paper studied four pretreatment methods by adding three different retention time organochlorine pesticides(α-BHC、Dieldrin、pp′-DDT) to fish sample and making different concentration(0.01、0.1、1),then using GC-ECD determinate its recoveries.

研究了用气相色谱——电子捕俘器法测定鱼肉中有机氯农药的四种不同前处理方法。通过向鱼样中加入三种不同保留时间的有机氯农药(α—六氯苯、狄氏剂、滴滴涕)，并测定三种不同浓度(0.01、0.1、1)时加标回收率。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.
