The result showed :(1) most of the samples have the comparability, only little of these samples exist obvious difference,(2) the quality index in a group have little diference,otherwise difference is obvious.(3) in the process of prescription ,we can use the quality simility to find the substitute when a kind of tobacco leaf in prescription is limited or absence.

结果表明，（1）大多数样本的品质指标存在相似性，少数样本则存在较大的差异；（2）属于同一类群样本的品质指标差异较小，属于不同类群样本的品质指标差异较大；（3）进行卷烟配方时，当需要的某一等级原料不足或缺乏时，可根据烟叶质量的相似性，从相同的类群中寻找。

The resistivity of filled skutterudites increases with the increase of the filling fraction. It originated from the decrease of carrier concentration in the skutterudite for the samples with high filling fraction and also the difference of the content of Fe Sb〓 and Sb in the samples.

填充型方钴矿材料的电阻率随填充率的提高而增大，这一方面是因为镧的引入使材料的载流子浓度降低，另一方面低填充率的样品中的低电阻率还与样品中的FeSb〓和Sb杂质的存在有关。

The low-temperature resistivity of filling skutterudite increases with the increase of temperature. However the slope of the resistivitytemperature curves are different. The curve of the sample with low filling fraction is smooth, and that of the samples with high filling fraction is sharp. It is caused by the existence of the impurities in the samples with low filling fraction.

填充型方钴矿材料的低温电阻率随镧填充率的变化规律与室温相同，但不同填充率的方钴矿材料的电阻率随温度变化的曲线的斜率不同，低填充率样品随温度变化趋势明显地比高填充率样品平缓，这种现象主要是由存在于低填充率样品中的杂质相引起的。

88 Yinchaihu commercial samples were collected from 27 provinces. On identification, only 52 samples (60%) complied with the species specified in the Chinese Pharmacopoeia which were derived from the root of Stellaria dichotoma L. var. lanceolata, Bunge and used in 24 provinces, and among them, about 2/3 were cultivated products grown for 1 or 2 years.

通过全国范围调查，收集到27个省、市、自治区的88份银柴胡生药商品，鉴定结果表明其中仅60％来源于中国药典品种，其余40％来源于非药典品种。52份来源于披针叶繁缕，在全国24个省市使用，其中，约有2／3为1或2年生栽培品。

Water samples were extracted and purified and collected by solid-phase extraction LC-18 column. Soil samples were extracted by ethyl acetate/petroleum ether (2:1, by vol) and purified by sulphonation. Wheat sample was extracted by acetonitrile/water (4:1, by vol) and purified and collected by SPE- Florisil column.

水样直接用LC-18固相萃取小柱分离、净化和富集；采用乙酸乙酯／石油醚（体积比2：1）振荡提取，磺化法净化，测定土壤中氯氟吡氧乙酸残留量；以乙腈／水（体积比4：1）为提取剂，氟罗里硅土固相萃取小柱分离、净化，测定小麦样品中氯氟吡氧乙酸的残留量。

Methods Pb and Cd in the samples were enriched in the sulphydryl cotton column under the conditions that the pH of the samples was adjusted to 7 and collected by washing the column with 4 ml of 0.2 mol/L HCl solution.

调节水样pH=7，使水样中痕量铅、镉同时富集在巯基棉柱上，再以4ml 0.2mol/L HCl溶液通过巯基棉柱进行洗脱、收集，以火焰原子吸收光谱法进行测定。

The test indicates:if the time of drying samples is more than 4 h,taking lithium tetraborate as flux,and temperature of melting samples controls at 1 100 ℃,the most stable percentages of gold and platinum can be determined,which are 0.243% and 0.174% respectively.

实验表明：样品干燥时间在4 h以上，然后以四硼酸锂为熔剂，熔样制片温度控制在1 100 ℃时，测得金和铂含量最稳定，其质量分数分别为0.243%和0.174%。

Methods:LPO content was determined by TBA-Acetic acid method.
