Combining with the measurements of scanning electron microscope, cathodoluminescence, energy dispersive spectroscopy, and photoluminescence, we establish that the origin of the Stokes shift in InGaN ternary compound arises from alloy composition fluctuations.

综合实验结果和许多文献资料，我们可了解样品的史托克位移效应和浓度调变间的关联性，并建立其产生的机制是由於样品制成过程中，难以避免的成份不均匀和相分离现象。

In this thesis, we contrastively studied the transport properties of series of pure or doped potassium blue bronzes and three kinds of purple bronzes, respectively. Our investigation may help to explore the CDW dynamical mechanism.

在本论文中，我们通过对系列掺杂蓝青铜样品及不同紫青铜样品的输运特性进行实验对比研究，尝试进一步揭示电荷密度波输运动力学以及杂质缺陷对其影响的微观实质。

The relative contents of thujopsene and cedrol were higher in P.orientalis extracted by SFE and MSD methods.No monoterpenes was found in the compounds extracted by SFE and SDE,and the wood resin acids were the major compounds in the compounds extracted by SE.

改装简易蒸馏样品和超临界CO_2萃取物以及并时蒸馏萃取物中含量最高的组分是罗汉柏烯和柏木脑，但是超临界CO_2萃取物中未检测出单萜；索氏提取法样品中含量最高的组分为非挥发性的树脂酸类物质。

Celestite samples were decomposed by both acid digestion and alkali fusion techniques.

利用酸溶法和碱熔法分解天青石样品，经过离子交换分离得到纯净的Sr，测定~(87)Sr/~(86)Sr同位素比值，实验结果表明两种样品分解方法得到的~(87)Sr/~(86)Sr同位素比值的偏差〈0。

Cepheid's easy-to-use systems integrate a number of complicated and time-intensive steps, including sample preparation, DNA amplification and detection, which enable the analysis of complex biological samples in its proprietary test cartridges.

易用的系统整合了一系列复杂和耗时的步骤，包括样品制备、DNA扩增及检测，这样就可以在公司专有的监测盒中分析复杂的生物样品。

It is found by X-ray diffraction that the solution of Sm2O3 and Gd2O3 in ceria for the samples sintered in the range of 1 400─1 550 ℃ is better, but for the sample sintered at 1600 ℃, a new phase is formed with the reduction of lattice constants.

X射线衍射分析发现：对1 4001 550 ℃烧结的样品，Sm2O3和Gd2O3固溶较好﹔但对1 600 ℃烧结的样品，有新相生成，同时晶格常数减小。

In the present study, 22 certified milk samples without melamine were collected, then 50 adulterated milk samples with added different content of melamine (0.1-1 500 mg·kg-1) were prepared. The near-infrared spectra of these milk samples were measured. The possibility of using NIR spectra to detect melamine in milk was studied.

采集了22个合格液态牛奶样品，并制备了50个掺入不同含量三聚氰胺(0.1～1 500 mg·kg-1)的牛奶样品，应用近红外光谱仪扫描其透射光谱，研究利用近红外光谱快速检测牛奶中三聚氰胺的可行性。

The molecular structure and chemical bond of Mn3O4 was analyzed by using FT-IR.

采用BET测定样品的比表面积，样品的比表面积为187 m2·g-1，孔体积为0.311991 cm3·g-1。

And the culturable bacterial degraders were increased from 10^6CFUg^(-1) soil to 10^8CFUg^(-1) soil after inoculating with the degrader. Moreover, the bacterial population increased faster in 100mgg^(-1) microcosoms than in 500mgg^(-1) microcosoms, revealing that the inoculated bacteria could survive and enhance the biodegradation of chlorophenol in cuntaminated soil.

接种外来微生物后，土壤中可以培养的氯酚降解菌的总数从开始的10^6CFUg^(-1)增加到10^8CFUg^(-1)，并且，在氯酚含量为100mgg^(-1)的土壤样品中，微生物数目的增加比在氯酚含量为500mgg^(-1)土壤样品中更快。

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。
