A new electrochemical method was established to analyze lead in samples by voltammetry of square wave leaching after pre-treatment of microwave irradiating digestions and the optimum determination conditions were explored.

摘要利用微波消解样品，再以电化学方波溶出伏安法检测样品中铅的含量并确定了最佳测定条件。

The range data acquired by 3D digitisers such as optical triangulation scanners commonly consist of depths sampled on a regulat grid,a sample set know as a range inage.

范围数据普遍藉着 3D立体 digitisers ，像是光学的三角测量扫描仪获得有深度在一个 regulat 格子上抽取样品，样品组知道如范围 inage。

There was no satistically significant difference among the quantitative results of plasma and serum DNA samples with diffemet dilutions (P＜0.05). The intra-assay and extra-assay CV were 11% and 17%, respectively.

对于不同稀释程度的血浆血清DNA样品(分别稀释为原浓度的50％、10％和1％)，定量检测结果与未稀释DNA样品的差异无统计学意义(P＜0.05)。

In this thesis, the solution of Chinese reference materials including lithium, potassium, calcium, sodium, magnesium, was used to evaluate analytical methods applied. Lithium was enriched in different eluents (hydrochloric acid, nitric acid and mixture with ethanol or methanol) by cation exchange resin AG 50W-X8, and the optional experimental conditions were studied.

本文以锂元素标准样品和钾、钠、钙、镁元素标准样品的混合溶液为主要研究对象，采用阳离子交换树脂AG-50W-X8来分离富集锂，探索在不同淋洗介质(包括盐酸、硝酸以及与甲醇、乙醇的混合)条件下锂分离纯化的最佳介质条件。

The present paper developed a new method in which extract analytes from seafood product s by DI water followed by precipitating proteins from extraction by trifluoroacetic acid and analyse polyphosphates in pre- pared extraction by suppressed conductivity ion chromatography whose gradient eluents were obtained by Eluent Generator.

本文建立了一种采用去离子水提取，三氟乙酸作为蛋白沉淀剂对海产品样品进行前处理，采用淋洗液自动发生装置在残产生 KOH 进行梯度淋洗，抑制型电导离子色谱法，检测海产品样品中多聚磷酸盐的方法。

本文建立了一种采用去离子水提取，三氟乙酸作为蛋白沉淀剂对海产品样品进行前处理，采用淋洗液自动发生装置在线产生KOH进行梯度淋洗，抑制型电导离子色谱法，检测海产品样品中多聚磷酸盐的方法。

Epidotes from different samples show considerable compositional variation,whereas those from the same sample are quite similar in composition, indica-ting that their composition is related.

s=0.23—0.37，但多为0.30—0.32，在不同样品中绿帘石成分变化很大，但同一样品中绿帘石变化不明显，说明其成分与全岩成分有关。

This equalities have no obvious dependence on luminosity also.

无论在全样品、光度分区还是在子样品中，我们发现二者具有相等的平均值，而且无明显的光度的依赖性。

After 10h ball milling, the alloy of carbonyl iron and carbonyl nickel began to form, and the sample kept its original bcc and fcc structure; after 100h ball milling, the sample became a solid solution with bcc structure; after 200h ball milling, the diffraction peak of Ni almost disappeared and the isotropic grains with D achieved, which was mainly attributed to the dislocations and disclinations of the nanocrystalline bcc FeNi suffering from severe plastic deformation by ball milling.

球磨10h时，羰基铁和羰基镍开始形成合金，但大部分Fe、Ni原子仍分别以bcc结构和fcc结构存在。球磨100h时，样品以bcc结构的FeNi合金为主，球磨200h后，样品中fcc结构Ni特征峰几乎消失，FeNi纳米晶达到最小粒径的平衡值，~8nm。高能球磨过程中，晶界区域的层错缺陷是合金化和纳米晶形成的重要因素。

超声波处理的酵母菌对发酵进程影响不大，均能正常发酵，对发酵后的酒样影响较大，经方差分析发现：酒度间存在显著性差异，超声波处理的酒度大部分降低，个别升高；残糖含量差异极显著，经超声波处理样品残糖含量均比对照高；各样品的总酸和挥发酸含量差异显著；超声波对总酚含量的影响不明显，对蛋白含量影响较大。

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.

要是在劳改农场，你等着挨绳子吧！
