In a low magnetizing field the coercivity of the non-aligned magnet is higher than that of the aligned magnet; the coercivity of the sample magnetized antiparallel to the aligned direction...

低场时非取向样品比取向样品的矫顽力大，外场反平行于取向方向比平行于取向方向的矫顽力大，而在足够大的外场下二者趋于相等。

The third part compares the different methods of digesting the soil, and selects the system of aqua regia -perchloric acid-hydrofluoric acid reagent.

第三部分对各种土壤样品的消解方法进行比较，选择王水—高氯酸—氢氟酸作为土壤样品的消解体系。

The sample was pretreated with 30% H2O2 and 2.5 mol/L NaOH,and then digested with aqua regia to make full oxidation of sulfur in thiolated chitosan resins to sulfate.

用w(H2O2)=30%溶液和2.5 mol/L NaOH溶液预处理样品，再用王水消解，样品中硫几乎完全转化为硫酸根。

Thus the sample size can be increased, and the nugget effect and detection limits can be decreased compared with normal Carius tube technique. This new technique is capable of digesting 12 g samples in a 75 mL Carius tube with 35 mL aqua regia at 320℃, and Re and all the PGEs can be measured.

由此可以加大取样量，降低铂族元素测定过程中的块金效应及检出限，使超低含量铂族元素的测定成为可能。12g样品在75mL卡洛斯管中用35mL王水于320℃溶解15h，基本上可以使各种地质样品中的铂族元素矿物完全溶解。

PAHs ratios are used to identify the source of PAHs, the result showed that the major source of 16 PAHs in Urumqi Xinshi district was coal-bustion and vehicle discharges . Mercury in TSP samples were digested by aqua regia and analyzed by AFS analyzer .The results showed that : the concentration of mercury was 0.869-1.91 ng m-3.Compared with other cities in the rest of the world , the concentration of mercury was very high. The concentration of mercury in heating season was lower than that in no-heating season.

对大气颗粒物样品中的汞，采用王水于特弗龙消解罐中加热消解的方法进行处理，稀酸定容后采用原子荧光光谱法对样品中的汞进行测定，测定结果为。869-1.91 ng m-3，与国外城市相比较高；实验测得非采暖期乌鲁木齐大气颗粒物汞浓度的均值高于采暖期颗粒物中的汞浓度，其原因可能是由于随着非采暖期温的升高，长期积累在土壤、水体环境中的汞向大气中释放，附着在颗粒物上，过了燃煤的影响。

As you rememjber you showed us other models of cases(not the same as 19000pcs we have purchased) please send from them(4-5models)to yiwu to mr askari or if it is difficult to dispatch them with visas to yiwu send them by any DHL or other express post.

您可能还记得，您给我们展示过样品（与我们买过的19000pcs型号不同），请将其（4-5个样品）发送到义乌市的阿斯卡里先生处，如果不能使用签证来发货，您可以通过敦豪速递公司或其他快递公司发送。

The precision parameter, RSD (n=10) of mineral elements in Astragal prepared by method is 0.2% to 12%.

采用焦化法制备黄芪样品，精密度统计结果表明，宁夏黄芪样品矿质元素的RSD(n=10)为0.2%～12%。

With microwave digestion and general digestion , the content of Pb and Cd in shrimp samples was measured by graphite furnace atonic absorption spectrometry .

采用微波消解与常规消解2种方法消解对虾样品，石墨炉原子吸收法测定其Pb、Cd的含量，对样品中Pb、Cd的微波消解与常规消解分析方法做了系统的比较。

The method was without complicated operation to the sample pretreatment, its automaticity was good and sensitivity was higher.

本方法无需用手工进行繁杂的样品前处理，简便易行，灵敏度高，已成功用于火电厂水汽样品中痕量铜的测定。

To evaluate the specificity of the PCR, genomic DNA of Theileria annulata,Babesia bovis,Toxoplasma gondii,Leishmania donovani and standard strain of N. caninum were used as a template in the PCR. For determining the detection limit of amplification procedure, PCR was run on a dilution series of genomic DNA from N. caninum（1.562 5-200 ng/ml）. Brain tissue samples of 32 aborted fetuses were detected by PCR-based assay, and 23 blood samples from mothers were tested by ELISA. Results The amplified DNA fragment （350 bp）had a high identity of 98% with the Nc-5 gene sequence of N.

以环形泰勒虫、牛巴贝斯虫、刚地弓形虫、杜氏利什曼原虫以及犬新孢子虫标准株DNA为模板进行扩增以验证PCR的特异性，采用紫外分光光度计测定犬新孢子虫标准株DNA浓度和纯度，取高纯度的DNA样品用灭菌水稀释，分别取不同量的DNA进行PCR扩增，确定PCR方法的敏感性；利用该方法对32份奶牛流产的胎牛脑组织样品进行检测，同时，对其中23份流产的母牛血样进行ELISA血清学检测，以评价犬新孢子虫PCR方法的检测效果。

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。
