Clay minerals in 15 surficial samples and 5 profile samples from the Yangtze Delta plain were analyzed by X-ray diffraction.

采用XRD研究了长江三角洲地区15个表层样品和5个剖面样品中的粘土矿物。

This could be done in practice by using an alkaline CsCl gradient, as the two DNA strands will denature at high pH.

用同样的样品和相同的技术手段即CsCl梯度离心将半保留复制和弥散复制区分开来的方法是将DNA样品变性，然后利用碱性CsCl梯度离心技术对单链DNA进行离心，半保留复制会出现两条带，而若是弥散复制则出现一条带，如下图所示

The ultraviolet spectrophotometry method as determining the content ofsapogenins was used to evaluate the change of the quality in Dioscorea Zingiberensis C.H. Wright before or after supercritical CO_2 fluid extraction. The content of sapogeninswas 2.03% and 1.84% respectively in original and depurative sample, which showed thatdepuration of Cu, Cd, Pb in Dioscorea Zingiberensis C. H. Wright by supercritical CO_2fluid extraction had little influence on the active ingredient.

2采用超临界CO_2流体萃取法提取黄姜中甾体皂素，以可见分光光度法测定其含量，得到黄姜原样品及重金属净化后样品中甾体皂素含量分别为2.03％和1.84％，超临界CO_2流体络合萃取黄姜中Cu、Cd、Pb后对其有效成分影响不大。

Slag-lime system autoclaved product compressive strength is different from the rule because of Al reacting with lime and forming an abundance of hydrogarnet, that induce product compressive strength descension.

矿渣蒸压样品的强度与矿渣红外光谱强吸收区Si-O伸缩振动频率表现出不同于其他两种固体废物的规律，矿渣中铝参与反应形成大量的水石榴石，导致其蒸压样品的强度下降。

In order to improve desorption/ionization effects, the purification methods for DNA samples are established.

为提高基体对样品解吸/电离效率，对纯化DNA样品的方法进行了讨论。

This article discribes the laboratory study of amplifying test of sensitivity and reliability to DY-1 total clones detecter and DY-2 Coli.

菌落总数和大肠菌群是水及饮料等液体样品中检菌率实验和现场取样品的卫生检测指标。

The internal reference was established by the universal primer pair CQUTC6/CQUTC7 for Tilletia genera, which could be used to determinate the reality of PCR system and exclude both false positive and false negative.

以腥黑穗菌属通用引物对CQUTC6/CQUTC7为内置对照，可以确定被检样品是否含PCR抑制物质进而判断检测体系是否正确，同时有效地排除样品检测结果的假阳性和假阴性。

We HAVE already senT the sample to you BY DHL, You will receive the sample VERY SOON.

我们已经用DHL把样品寄送给你，你将会在两天后收到样品，期待你满意的回复。

3 Specimen Description—Examples of typical oor-mounted test specimens are shown in Fig. 1 in diagrammatic form.

8.3 样品的描述——典型的楼面安装的测试样品以图解形式示于图1。

For functions of them ,the delta method implies the following result, proved in Section 14.1.4: Let denote a differentiable function of , with sample value for a multinomial sample.

为作用的他们，三角洲方法暗示以下结果，被证明在部分14.1.4：让表示一个能区分的作用，以样品价值为一个多项式样品。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
