It was used for detection of virus RNA in AIV infected chicken embryo allantoic fluids clinical specimens from various avian.

建立并优化了检测禽流感病毒核酸的探针杂交法，探针杂交法能鉴别出非免疫鸡胚和SPF鸡胚尿囊液中的病毒，攻毒后第 3天的 SPF和非免疫鸡泄殖腔拭子中 AIV的最大检出率为 1/10 ，对临床样品中的 AIV的最大检出率为 1/7，而直接 HA和 HI法及 AGP试验检不出临床样品的 AIV。

We also for the first time compared the the storage stability of the allylamine plasma samples in the different mediums , including the hydrophilicity and biocompatibility, and the results indicated the samples had good stability in the different mediums.

同时还首次比较了丙烯胺等离子体修饰样品在多种不同介质中的储存稳定性，包括亲水性和生物相容性，结果显示样品在不同介质中均有较好的稳定性。

After centrifugation, the extracts were separated on HILIC column by using acetonitrile-water as mobile phase. The analytes were identified and quantitated by LC-tandem MS under the positive/negative electrospray ionization and multiple reaction monitormode. The calibration curves showed good linearity in the range of 25-5000 μg/kg for melamine and cyanuric acid, and 50-10000 μg/kg for ammeline and ammelide. The limits of detection and limits of quantification were in the range of 5-20 μg/kg and 50-100 μg/kg, respectively.

牛奶样品直接用乙腈超声波提取；奶粉样品先用水溶解后再加乙腈超声波提取，高速离心后以乙腈－水为流动相，采用亲水作用色谱柱分离这4种化合物，在电喷雾正、负电离切换多反应监测模式下进行定性与定量分析，三聚氰酸一酰胺与三聚氰酸二酰胺含量在50~10000μg/kg之间、三聚氰胺与三聚氰酸在25~5000μg/kg之间，均获得良好的线性。

No amoebic cysts or trophozoites were found from 12 water samples collected from schools or patient′s houses, but the Esherichia coli level exceeded the national standard in 7 samples.

两所学校自来水和10例发病者家庭井水样品中7份样品的大肠埃希菌指标超过国家标准（≥50），但均无溶组织内阿米巴滋养体或包囊污染。

The systematic analysis on the magnetic characteristics of street dust from Xi′an city indicates high concentration of magnetic minerals corresponding to the high value of the magnetic susceptibility, the anhysteretic susceptibility and the saturation isothermal remnant magnetization.

西安市道路表面灰尘样品的环境磁学研究显示磁化率、非磁滞磁化率以及饱和等温剩磁均比较高，表明样品中磁性矿物含量较高。

Mainly research results were as follows:(1)Proper scanning conditions which were used for establishing NIRS nondestructive detecting models were confirmed.The results of test indicated that proper scanning times was 1 times to one point;proper scanning manner was 2 times by 180°running to several points; the enactment of scanning parameters simply satisfied the condition that the spectral line of samples and the spectral line of contrast were tangent in conquest line;it can obtain the greatest prediction performance with the spectral data which were determined in an aphotic room absolutely.

具体的研究结果如下：(1)南果梨近红外透射光谱的适宜扫描方式为以果柄-果蒂为轴1 80°转动扫描2次、适宜的光谱扫描次数为单测点扫描一次、扫描参数的设定只要满足待测样品光谱曲线和参照物光谱曲线均在特征峰处相切于征服线即可，光谱测定的最佳环境条件为在完全遮光的房间内进行样品光谱的采集。

Companies also differ markedly in their beliefs about the efficacy of such promotions: whereas over 50% of sales at Estee' Lauder are associated with free gift with purchase promotions, chanel does not offer any, and Aramis is moving from gifts to sampling, with over a quarter of its marketing budget devoted to free samples of newly introduced products.

公司对於这种促销效力的看法也明显不同：与&雅诗兰黛&有超过50%的销售是和购买促销活动的免费赠品有关而相反的是，&香奈儿&并不提供任何东西，而&雅男士&则把赠品换成样品，将它超过四分之一的行销预算投注在新上市产品的免费样品上。
