6Research on the properties and microstructures of 27Cr-7Ni-4Mo super duplex stainless steel显示文摘In this study,metallographic analysis and nanoindentation characterization were used to analyze the properties and microstructures of as-cast nitrogen alloyed 27Cr-7Ni-4Mo super duplex stainless steel(super-DSS).The as-cast microstructure of the super-DSS was characterized by its ferrite and island-like austenite phases.During the solution annealing process,the austenite volume percentage of the steel decreased gradually with increased annealing temperature.As a main element,the chromium content in the ferritic and austenitic phases elevated slightly at first then decreased with increased annealing temperature.The chromium partition coefficient in the steel varied by around 1.0.The contents of nickel,another main alloy element,also increased in the ferritic and austenitic phases with increased annealing temperature,as did the nickel partition coefficient in the steel,which tended to be close to 1.0.The nanoindentation characterization results indicate that the hardness of the austenite phase is slightly greater than that of the ferrite phase.They were similar to each other within a certain temperature range from1 050 ℃ to 1 100 ℃.This temperature range was consistent with the temperature range in which the content ratio of the two phases was close to 1∶ 1.We found the Young's modulus of the ferrite phase to be greater than that of the austenite phase.With increased annealing temperature,the Young 's modulus of the ferrite phase decreased while that of the austenite phase remained almost unchanged.PENG Shidan LIU Xiaorong ZHOU Candong 2016Baosteel Technical Research2016,10,3:0
7Extensible Framework for Rao-Blackwellized Filtering显示文摘The Rao-Blackwellized Particle Filter (RBPF) is widely used for high dimensional nonlinear systems, often with a linear Gaussian substructure. However, the RBPF is just a specific method in the class of Rao-Blackwellized Filtering (RBF). This paper analyzes the recursive structure of the RBF from a more general perspective. The research starts from a general system model and studies the interconnected relationships between the two subspaces during the iterations. The results illustrate the working mechanisms of the RBF with an extensible framework for easily building Rao-Blackwellized algorithms with common nonlinear filters. Several examples are given to illustrate how to build new filters using this framework.Shidan Li Xin Li Liguo Sun Desheng Wang 2012Tsinghua Science and Technology2012,17,3:0
8Exergy Analysis and Thermal Optimization of a Double-Turbine Regeneration System in a Ultra-Supercritical Double-Reheat Unit显示文摘Improving the primary steam parameters is one of the most direct ways to improve the cycle efficiency of a powergeneration system. In the present study, the typical problem connected to the excessively high superheat degree ofextraction steam in an ultra-supercritical (USC) double-reheat unit is considered. Using a 1000 MW power plantas an example, two systems (case 1 and case 2) are proposed, both working in combination with a regenerativesteam turbine. The thermal performances of these two systems are compared with that of the original systemthrough a heat balance method and an exergy balance strategy. The results reveal that the two coupled systemscan significantly reduce the superheat degree of extraction steam, turbine heat rate, and coal consumption of theunit and improve the energy utilization efficiency. These results will provide useful theoretical guidance to futureinvestigators wishing to address the general problem relating to energy conservation and modelling of the coupledextraction steam regenerative system of USC double-reheat units.Shidan Chi Tao Luan Yan Liang Xundong Hu Yan Gao 2021Fluid Dynamics & Materials Processing2021,17,1:0
9Surveillance system-based physician reporting of pneumonia of unknown etiology in China:A cross-sectional study显示文摘Objective:To describe the current reporting of pneumonia of unknown etiology(PUE)and factors that affect reporting by clinicians in China using the PUE surveillance system in order to provide a reference for improving PUE reporting rates in the future.Methods:Clinicians were recruited via the Sojump platform and requested to complete an anonymous self-administered questionnaire.Multivariate logistic regression analysis was used to assess factors influencing clinicians’reporting activities.Results:This study showed a low PUE case reporting rate and a poor understanding of PUE reporting among the investigated clinicians.Of the 136 clinicians who had diagnosed PUE cases,multivariate logistic regression analysis results showed that clinicians who had attended in-hospital training were more likely to report PUE than those who had not(OR 4.48,95%CI 1.49-13.46).Clinicians with an expert panel on PUE in their hospital were more likely to report PUE cases than those without(OR 5.46,95%CI 1.85-16.11).Conclusions:There is a need to promote and reinforce PUE surveillance system training among medical staff.In addition,PUE testing technologies in hospital laboratories should be upgraded,especially in primary and unclassified hospitals,to increase surveillance efficiency and improve PUE reporting rates.Hongchun Du Yajuan Zhu Yan Chen Shidan Zhou Jiani Tong Yingnan Deng Dingmei Zhang 2022Asian Pacific Journal of Tropical Medicine2022,15,4:0
