| 2 | Study on segmented distribution for reliability evaluation显示文摘In practice, the failure rate of most equipment exhibits different tendencies at different stages and even its failure rate curve behaves a multimodal trace during its life cycle. As a result,traditionally evaluating the reliability of equipment with a single model may lead to severer errors.However, if lifetime is divided into several different intervals according to the characteristics of its failure rate, piecewise fitting can more accurately approximate the failure rate of equipment. Therefore, in this paper, failure rate is regarded as a piecewise function, and two kinds of segmented distribution are put forward to evaluate reliability. In order to estimate parameters in the segmented reliability function, Bayesian estimation and maximum likelihood estimation(MLE) of the segmented distribution are discussed in this paper. Since traditional information criterion is not suitable for the segmented distribution, an improved information criterion is proposed to test and evaluate the segmented reliability model in this paper. After a great deal of testing and verification,the segmented reliability model and its estimation methods presented in this paper are proven more efficient and accurate than the traditional non-segmented single model, especially when the change of the failure rate is time-phased or multimodal. The significant performance of the segmented reliability model in evaluating reliability of proximity sensors of leading-edge flap in civil aircraft indicates that the segmented distribution and its estimation method in this paper could be useful and accurate. | Li Huaiyuan Zuo Hongfu Su Yan Xu Juan Yin Yibing | 2017 | Chinese Journal of Aeronautics2017，30，1： | 4 |
| 3 | Recent advances in non-thermal plasma(NTP)catalysis towards C1 chemistry显示文摘C1 chemistrymainly involves the catalytic transformation of C1molecules(i.e.,CO,CO2,CH4 and CH3OH),which usually encounters thermodynamic and/or kinetic limitations.To address these limitations,non-thermal plasma(NTP)activated heterogeneous catalysis offers a number of advantages,such as relatively mild reaction conditions and energy efficiency,in comparison to the conventional thermal catalysis.This review presents the state-of-the-art for the application of NTP-catalysis towards C1 chemistry,including the CO2 hydrogenation,reforming of CH4 and CH3OH,and water-gas shift(WGS)reaction.In the hybrid NTP-catalyst system,the plasma-catalyst interactions aremultifaceted.Accordingly,this reviewalso includes a brief discussion on the fundamental research into themechanisms of NTP activated catalytic C1 chemistry,such as the advanced characterisation methods(e.g.,in situ diffuse reflectance infrared Fourier transform spectroscopy,DRIFTS),temperatureprogrammed plasma surface reaction(TPPSR),kinetic studies.Finally,prospects for the future research on the development of tailor-made catalysts for NTP-catalysis systems(which will enable the further understanding of its mechanism)and the translation of the hybrid technique to practical applications of catalytic C1 chemistry are discussed. | Huanhao Chen Yibing Mu Shanshan Xu Shaojun Xu Christopher Hardacre Xiaolei Fan | 2020 | Chinese Journal of Chemical Engineering2020，28，8： | 2 |

| 8 | Responses of ground-dwelling spiders to four hedgerow species on sloped agricultural fields in Southwest China显示文摘Spiders are important predators in agroecosystems and contribute to the control of agricultural pest populations. Habitat manage- ment such as the creation of new semi-natural habitats around or within fields enhances spider abundance and species diversity. Using pitfall traps, we investigated the effects of four hedgerow plant species, which serve as undisturbed and permanent semi-natural habitats, on ground-dwelling spider activity density (a parameter of population density and relative activity) and species richness. Samples were collected over two winter wheat and two summer maize growing seasons during 2005-2007 in trial field 1 (slope gradient of 20%) and field 2 (slope gradient of 12%) at the Ziyang Experimental Site in Sichuan Province, China. The hedgerow species evaluated were Amorpha fruticosa (field 1), Vetiveria zizanioides (field 1), Eulaliopsis binata (field 2), and Medicago sativa (field 2). Compared to control plots, hedgerow plots had significantly higher activity density and species richness of ground-dwelling spiders within strips in both fields 1 and 2 during the wheat growing season. The presence of hedgerow strips did not augment the activity density and species richness of ground-dwelling spiders within the crop fields during the wheat or maize growing seasons. The ground-dwelling spider activity density within hedgerow strips was significantly higher in the Vetiveria than in the Amorpha plots and in the Medicago than in the Eulaliopsis plots, and the species richness was significantly higher in the Vetiveria than in the Amorpha plots during the wheat season. Our results suggest that hedgerows may serve as important overwintering sites for ground-dwelling spiders during the wheat growing season. In addition, the diversification of agroecosystems by using hedgerow strips may be a viable strategy for maintaining ground-dwelling spider populations in agricultural areas. However, ground-dwelling spiders did not move into adjacent crop fields; therefore, future work should address the mechanisms of attracting spiders into crop fields, thereby contributing to the bio-control of pests. | Yuhong Wu Qingnian Cai Chaowen Lin Yibing Chen Yuying Li Xu Cheng | 2009 | Progress in Natural Science:Materials International2009，19，3： | 1 |

| 15 | Diagnostic performance of different specimens in detecting enterovirus A71 in children with hand,foot and mouth disease显示文摘Hand,foot and mouth disease(HFMD)is a major public health problem among children in the Asia-Pacific region.The optimal specimen for HFMD virological diagnosis remains unclear.Enterovirus A71(EV-A71)neutralizing antibody titres detected in paired sera were considered the reference standard for calculating the sensitivity,specificity,positive and negative predictive value of throat swabs,rectal swabs,stool,blood samples and cerebrospinal fluid(CSF)by RT-PCR or ELISA assay.In this study,clinical samples from 276 HFMD patients were collected for analysing the sensitivity of different kind of specimens.Our results showed that stool had the highest sensitivity(88%,95%CI:74%–96%)and agreement with the reference standard(91%).The order of diagnostic yield for EV-A71 infection was stool samplerectal swab>throat swab>blood sample>CSF sample,and using a combination of clinical samples improved sensitivity for enterovirus detection.The sensitivity of ELISA for IgM antibody detection in sterile-site specimens was significantly higher than that of RT-PCR(serum/plasma:62%vs.2%,CSF:47%vs.0%)(P<0.002).In conclusion,our results suggest that stool has the highest diagnostic yield for EV-A71-infected HFMD.If stool is unavailable,rectal swabs can be collected to achieve a similar diagnostic yield.Otherwise,throat swabs may be useful in detecting positive samples.Although IgM in blood or CSF is diagnostically accurate,it lacks sensitivity,missing 40%–50%of cases.The higher proportion of severe cases and shorter interval between onset and sampling contributed to the increase in congruency between clinical testing and the serological reference standard. | Yonghong Zhou Chongchen Zhou Kai Wang Qi Qiu Yibing Cheng Yu Li Peng Cui Lu Liang Peng Li Xiaowei Deng Lili Wang Wen Zheng Hui Gong Fang Wang Meng Xu Justin Jang Hann Chu Lance Turtle Hongjie Yu | 2023 | Virologica Sinica2023，38，2： | 1 |
