Hypothesis testing for reliability with a three-parameter Weibull distribution using minimum weighted relative entropy norm and bootstrap

引用

Journal of Zhejiang University-Science C(Computers and Electronics) 2013年第2期14卷 143-154页

作者： Xin-tao XIA Yin-ping JIN yong-zhi xu Yan-tao SHANG Long CHEN School of Mechatronical Engineering Henan University of Science and Technology School of Mechatronical Engineering Northwestern Polytechnical University

With the help of relative entropy theory,norm theory,and bootstrap methodology,a new hypothesis testing method is proposed to verify reliability with a three-parameter Weibull *** on the relative difference information of the experimental value vector to the theoretical value vector of reliability,six criteria of the minimum weighted relative entropy norm are established to extract the optimal information vector of the Weibull parameters in the reliability experiment of product *** rejection region used in the hypothesis testing is deduced via the area of intersection set of the estimated truth-value function and its confidence interval function of the three-parameter Weibull *** case studies of simulation lifetime,helicopter component failure,and ceramic material failure indicate that the proposed method is able to reflect the practical situation of the reliability experiment.

Synthesis of Cordierite by Decomposition of Metal Nitrates on the Surface of Carbon Black Powder

引用

Journal of Wuhan University of Technology(Materials Science) 2004年第4期19卷 103-105页

作者：谢志勇 Tianjin University

Cordierite precursor was obtained through a process, which involved the decomposition of metal nitrates on the surface of ultrafine carbon black powder between 100-300℃ and the gasification of the carbon black at higher temperature in air. The average size of the particles, which were heat-treated at 700℃ for 10h, is about 1020nm, and the specific surface area is about 129m 2/g. The experimental results show that the ultrafine particles of cordierite precursor can be produced by this process. The precursor powder was calcined at different temperatures. X-ray diffraction examination indicates that β-quartz is crystallized from the amorphous matrix around 850℃ firstly and then MgO-Al 2O 3 spinel and α-cordierite appears. Above 1000℃, MgO-Al 2O 3 spinel and cristobalite disappear gradually and form an intermediate phase (sapphirine). At around 1300℃, the main phase is α-cordierite, and no other phase is detected.

Role of the Chinese Herbal Medicine Xianhuayin on the Reversal of Premalignant Mucosal Lesions in the Golden Hamster Buccal Pouch

引用

International Journal of Oral Science 2010年第1期2卷 53-58页

作者： Yan-zhi xu yong-le Qiu zhi-guang An Feng-ying Yang Department of Stomatology The Fourth Hospital of Hebei Medical University Shijiazhuang China

Aim To investigate the role of the Chinese herbal medicine Xianhuayin on the reversal of 7,12-dimethylbenz[a]anthracene （DMBA）-induced premalignant mucosal lesions in the oral buccal pouch of golden hamsters. Methodology The animals were randomly divided into a non-diseased control group （n=5） and an experimental group including 50 animals in which the buccal mucosa had been painted with DMBA （0.5% in acetone） to generate an oral mucosa premalignant lesion. Animals in the experi- mental group were further divided into Xianhuayin-treated group （n=30）, untreated prem＇alignant lesion group （n=10） and normal saline （NS）-treated group （n=10）. The cheek （buccal） pouch mucosa of the golden hamsters in each group was observed with light and electron microscopy eight weeks after intragastric administration with NS or Xianhuayin. Results In the non-diseased control group, the buccal mucosa was keratinized and stratified squamous epithelium under a light microscope. In the untreated premalignant lesion group, variable degrees of epithelial dysplasia was observed. The irregular epithelial mucosa gradually became distinct in the Xianhuayin-treated group. Scanning electronic microscopic （SEM） analysis showed that surface of the cells exhibited honeycomb structures in the hamster of untreated- group. The cells were morphologically irregular, overlapped and loosened in the untreated premalignant lesion group. Most of the cell surface exhibited honeycomb structure in the Xianhuayin-treated group. Transmission electronic micro- scopic （TEM） analysis showed that buccal mucosal epithelial cells were morphologically regular in the non-diseased control group. Desmosomes and tonofibrils were reduced and the nucleus was morphologically irregular in the untreated premalignant lesion group. In the Xianhuayin-treated group, the widening intercellular gap was gradually reduced, desmosomes and the cells becoming morphologically regular. No significant difference was observed between the hamster
