Gaolan Hill section is in the southern Lanzhou City with a total thickness of 240 m. 422 paleomagnetic block samples were obtained from the field with an approximate spacing interval of 0.5 m. All samples were demagnetized in a thermal demagnetiser systematically, and then the Nature Remanent Magnetization was subsequently measured using a superconducting magnetometer from room temperature to 500 ℃ in 50 ℃ steps.

The △m plot shows a minus curvature, which also means demagnetizing character in magnetic nanowires system. The △m plot becomes asymmetric with the increase of diameters.

样品的△m Plot表现出负的曲率，同样证明样品中存在退磁性特点的相互作用，大直径的样品的的△m Plot则表现出不对称现象。

The influence of CFC-12 content, effect of fluorination temperature and fluorinating time on the structure and hydrodesulfurization activity of the catalysts were examined systematically. The results revealed that hydrodesulfurization activity of the catalyst fluorinated by 1% CFC-12 at 623 K was obviously improved With an increase of 20%-30% as compared With that of the unfluorinated catalyst, the commercially available BY2 catalyst, and NH4F-fluorinated catalysts.

通过对0.5%~7%各种氟里昂浓度和473~773K各种温度及不同时间氟化处理的样品进行详细考察，发现在623K下由含氟里昂1%的湿空气氟化的载体制备的催化剂样品，其噻吩的加氢脱硫的活性有明显改善，相对於非氟化样品、BY-2工业催化剂以及氟化铵溶液浸渍处理的催化剂活性提高20%~30%，且非常稳定。

The samples have lower permittivities by adding MgO before Ba0.6Sr0.4TiO3 powder be pre-synthesized, but have higher tunabilities and lower high frequency losses by adding MgO after Ba0.6Sr0.4TiO3 powder be pre-synthesized. The tunabilities of the samples prepared by adding 15%~25% MgO after Ba0.6Sr0.4TiO3 powder be pre-synthesized are all higher than 20% at 103 V/mm.

MgO添加量相同时，在预合成BSTO前加入，样品的介电常数较低；在预合成BSTO后加入，样品的高频损耗较小，可调性较高，当添加质量分数为15%~25%的MgO，样品在10^3V/mm电场强度下的可调性均高于20%。

When applied to the sample pad, the liquid sample migrates by capillary diffusion through the conjugate pad, rehydrating the gold conjugate and allowing the interaction of the sample analyte with the conjugate.

当液体样品用在样品垫上，液体由毛细作用力扩散通过金标垫，使金标复水并使得样品中的分析物特异性作用于金标。

The recombinant viruses, with the gene of reference RV strain VP2, field strain T114 VP6 and T73 G1-serotype VP7, respectively, co-infected Sf9 cell at a multiplicity of infection of 0.5. Harvested the supernatants of culture when the cells were lysed fully (about 7-10 days), or harvested cells before cell lysates (about 4-5 days after infection) and then treated the cells with lysing solution. The supernatants of and cell lysates were ultracentrifuged twice with 40% sucrose cushion at 93 000g, and the sediment products were harvested with TNC buffer. The purified VLPs samples were separated by SDS-PAGE, and then stained by Coomassie blue and silver nitrate and detected by Western blot to analyze the composition of VP2, VP6 and VP7 and their specificity. The morphologic structure of recombinant VLPs was detected by EM.

Experiment results indicate the HN derivatization method is not effective for test objects of complicated ingredients, such as gaba tea, germinated brown rice and germinated seed samples. We were unable to identify the GABA peak on the HPLC spectrum. When dealing with samples that contain large amount of amino acid, such as germinated brown rice and sprouted seeds, the PITC derivatization method is prone to disturbance and has the tendency to overestimate the GABA content. The OPA derivatization method effectively isolates the GABA peak of all test samples of this experiment. That its derivatization is simple and speedy makes it suitable for broader applications.

实验结果显示HN衍生法对於成分复杂的检品如茶汤、发芽玄米、发芽种子样品的分析效果皆不好，在HPLC图谱上无法辨识GABA peak；PITC衍生法对於含有大量蛋白质胺基酸的样品如发芽玄米、发芽种子则较易受干扰而可能高估GABA含量；OPA衍生法对於本实验所有样品中的GABA peak均有良好的分离效果，且衍生化过程简单快速是较建议广泛适用的检测方法。
