分离样本与复合样本统计证据推断的一致性

证据理论是不确定性推断的重要方法。在统计证据推断中，遗留了近二十年的分离样本观测证据支持函数的合成结果与复合样本观测证据支持函数的一致性的问题，部分地得到了解决，对容量为２的样本观测证据情况，提出了使其具有一致性的充分必要条件，并给出了这一条件的几何解释。

hv-block交叉验证法在率定水文模型参数中的比较研究

本文指出了应用分离样本验证法率定水文模型参数的不足,引入并探讨了hv-block交叉验证法的适用性,并与分离样本验证法进行比较。不同流域、不同系列长度和不同时段资料的计算结果表明,hv-block交叉验证法的模拟预报精度要明显优于分离样本验证法,该法能够充分利用资料信息,特别是当资料系列较短的情况下,其优越性更加突出。

基于权重散射特征的FSVM算法在极化SAR影像分类中的应用

提出了一种基于权重散射特征的模糊支持向量机的极化SAR数据监督分类方法。首先,对极化SAR数据进行H/SPAN/A/α散射特征提取;其次,根据样本可分离度设置最佳散射特征权重参数C,得到最优分类输入数据(H/6SPAN/A/α);最后,利用FSVM算法对数据进行监督分类。实验结果证明,所提出的FSVMH/6SPAN/A/α分类结果优于FSVM-H/SPAN/A/α。

Beneficiation study of Eshidiya phosphorites using a rotary triboelectrostatic separator

This study was performed to investigate the feasibility of applying a Rotary Triboelectrostatic Separator（RTS） to the beneficiation of Eshidiya phosphate minerals.RTS separation tests were carried out on phosphatic bed A_1,phosphatic bed A_3 and slime samples.The bed A_1 and slime samples were tested without desliming.Two sets of tests were performed using the A_3 sample： one was performed without desliming and the other with the A_3 sample deslimed.RTS separation tests as initially performed on the bed A_1 and slime samples gave products that had essentially the same P_2O_5 content.This indicated that adsorbed clay particles on the phosphate surface are responsible for the poor separation of un-deslimed phosphates.Better triboelectrostatic separation was observed with the undeslimed A_3 phosphate sample;these tests resulted in a highest product grade of 26%P_2O_5.The deslimed A_3 sample showed far more effective separation than the undeslimed A_3 one.In fact,a concentrate of 34%P_2O_5 was obtained from the triboelectrcstatic separation of deslimed A_3.The results indicate that with deslimed A_3 P_2O_5 recovery was about 65%for a concentrate of 28%P_2O_5 and about 45%for a concentrate of 30%P_2O_5.These results clearly show the importance of desliming for effective beneficiation of phosphate by the RTS.A more efficient separation can be expected from optimized operating conditions and circuit configuration.

Biofilm Determination of Listeria monocytogenes That Isolated from Different Sources

The study was conducted for the detection of Listeria monocytogenes bacteria from different sources （CSF and blood） obtained from patients in Pediatric hospital and from food sources like （yogurt, raw vegetables and raw milk, sausage）. Ten isolates were isolated from 150 specimens one of them from CSF and one isolate isolated from blood samples the others isolated from food specimens 6 isolates isolated from sausage and 2 from raw vegetables. Isolates were identified traditionally involved culture methods based on selective enrichment and plating followed by the characterization of Listeria spp. based on colony morphology, sugar fermentation and haemolytic properties, identification by Api listeria was done. Determine the isolates that produce biofilm by tissue culture plate method. The highest biofilm forming strains ofListeria monocytogenes isolates appear in No. （D10, El, E5 and E7） OD reading each of them is （0.13, 0.09, 0.11 and 0.19） respectively, the lowest or poor biofilm forming strains appear in No. （D11, D12, E2, E3, E4 and E6） that optical density （OD） reading are （0.04, 0.03, 0.05, 0.04, 0.05 and 0.03） respectively by comparing with control prepared in well （A12） that stained by crystal violate without putting any isolates and the OD reading is （0.003）. Confirmation by PCR was done only for four isolates that produce biofilm （D10 and El） that obtained from CSF and blood sample and for （E5 and E7） that obtained from food samples.

皮脂分泌物中人体蠕形螨分离方法的改进

目的探索人体蠕形螨更加精准、清晰的样本分离方法。方法采用自制刮取式取螨器、昆虫针作为取螨工具,选用2%(安利)餐具洗洁精作为皮脂溶解剂,用凹玻片作为清洗容器,从受检者皮脂分泌物中分离出清洁活螨的方法。结果从57位中、重度感染患者鼻部、额部、背部皮脂分泌物中共分离出了301条清洁的毛囊蠕形螨和47条皮脂腺蠕形螨。结论该法可快速、完整地分离出人体清洁活螨,为进一步开展人体蠕形螨的研究奠定基础。
