We select the polyamide resins, the polyurethane resin mixed with isopropyl alcohol and ethyl acetate component solvent, form the plastic printing ink of non-benzene solvent, use the IGT printability meter, the transmission density meter, the magnetic force mixer and many kinds of measuring instrument, measure the sample printing ink printed on the commonly used package printing film. The performance, the printability and the color characteristic of non-benzene solvent ink for plastic film printing were researched with the development printing ink sample.

结合与之相适应的树脂、颜料和助剂，开发研制了以聚酰胺树脂、聚氨酯树脂与醇、酯混合溶剂形成油墨连结料的无苯型塑料凹印油墨，并结合塑料凹印工艺要求，采用IGT印刷适性仪、透射密度仪、磁力搅拌器等多种测试仪器，通过对各种包装常用承印材料及样品油墨的测试，探讨了研制油墨样品的性能、印刷适性和颜色特性。

Remanence intensity of lunar samples are negative related to the abundance of iron, materials which were formed between 3.6~3.8 Ga can gain strong remanent magnetism.

月球样品的剩磁强度与铁的丰度呈负相关，在38~36亿年间形成的岩石样品剩磁强度最大。

Finally, aluminium alloy foam specimen with different structural parameters were made to investigate the variation of underwater sound absorption coefficient.

最后，本文利用前面得到的低压渗流法的较佳的工艺参数，制备了不同结构参数的泡沫铝样品，并研究了样品的水下声吸收系数的变化规律。

Relative dating assesses the age of a specimen in comparison to other specimens .

一种是测定相对年龄，通过与其他的样品的比较来确定待测样品的年龄。

Multiple experiments such as grain-sized separation , magnetic mineral analysis, magnetic parameters measurement were made on 110 surface samples and 64 samples of the 180 core sediment taken from the shelf of the East China Sea to abyssal plain of the Okinawa Trough .

本文选取东海陆架至冲绳海槽槽底平原的代表性沉积样品110个和已有研究基础的DH180岩心样品，通过颗粒分离、磁性矿物分析、趋磁细菌培养、浮游有孔虫δ~(18)O测定、AMS~(14)C测年、多种磁学参数测量(包括磁化率、等温剩磁、x-T热磁曲线、磁滞回线、非磁滞剩磁和饱和等温剩磁等)等试验手段，分析探讨了不同粒级沉积物对磁性的贡献、沉积物磁性与物质来源及环境的内在联系、短期古海洋事件的环境磁学表现等科学问题。

16 PAHs in the leaves of 9 kinds of broadleaved plants from Baiyun Mountain in Guangzhou were separated and analyzed quantitatively by GC-MS.

采集了白云山9种阔叶植物叶片样品，利用GC-MS对样品中的多环芳烃进行了定量分析。

In comparison with general tiger's-eye stone, its w/w(Fe 2O 3+FeO) adds from 018 to 022, there is not abnormal reaction under Chelsea color filter , it appears as dark green color. So it can be preliminarily decided that its color is caused by Fe 2+.

从w /w (Fe2 O3+FeO)值来看，常见的黄色虎睛石为 0 1 8，绿色虎睛石为 0 2 2 ，结合样品在滤色镜下无异常反应和样品呈暗绿色的特点，可初步判断其颜色由Fe2 +所致。

The fitting of XRD using the standard Rietveld technique indicates that the samples can be indexed by a tetragonal lattice with space group I4/mmm.

室温XRD测量表明所有掺杂的样品都是Bi-2223相，用Rietveld技术拟合得到所有样品是四方结构的，空间群是14/mmm。

DNA molecular weight standards are a mixture of a grou Pof DNA molecules with known sizes to reference the molecular weight of unknown DNA samples in nucleic acid electrophoresis and hel Pthe experimentalists to judge the property of the DNA samples.

DNA分子量标准是一组分子量大小已知的DNA片段混合物，用于指示核酸电泳中未知样品的分子量大小，从而帮助实验人员判断DNA样品的性质。

The longest lifetime component in PALS results is ascribed to the annihilation of positronium in cavities of PS sample. It is found that 80% of the positrons implanted in PS film have formed positronium atoms. PALS results show that the lifetime of ortho-Positronium has small value when the sample was in oxygen gas medium compared with those in other medium.

正电子湮没寿命谱测试结果表明，样品中存在长达40ns的电子偶素湮没成分，并且进入多孔硅膜层的正电子约有80%形成电子偶素，具有非常高的电子偶素产额；在氧气气氛下，由于气体导致o-Ps发生自旋转化猝灭是使多孔硅样品中电子偶素寿命缩短的主要原因。

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。
