| 2 | Feasibility Analysis of the Operation Strategies for Combined Cooling, Heating and Power Systems (CCHP) based on the Energy-Matching Regime显示文摘Although numerous studies have considered the two traditional operation strategies:following the electric load(FEL)and following the thermal load(FTL),for combined cooling,heating,and power(CCHP)systems in different case studies,there are limited theoretical studies on the quantification methods to assess the feasibility of these two strategies in different load demands scenarios.Therefore,instead of a case study,we have undertaken a theoretical analysis of the suitable application scenarios for FEL and FTL strategies based on the energy-matching performance between systems'provision and users'demands.To compare the calculation models of energy saving rate(ESR)for FEL and FTL strategies in the left and right sub-regions of the energy-supply curve,a comprehensive parameter(^)that combines three inherently influential factors(off-design operation parameter,energy-matching parameter,and install capacity coefficient)is defined to determine the optimal installed capacity and feasibility of FEL or FTL strategies quantitatively.The results indicate that greater value of x contribute to a better energy saving performance,and FEL strategy shows better performance than FTL in most load demands scenarios,and the optimal installed capacity occurs when the load demand points were located in different regions of the energy-supply curve.Finally,taking a hotel in Beijing as an example,the value of the optimal install capacity coefficient is 0.845 and the FEL strategy is also suggested,and compared to the maximum install capacity,the average values of the ESR on a typical summer day,transition season,and winter can be enhanced by 3.9%,8.8%,and 1.89%,respectively. | FENG Lejun DAI Xiaoye MO Junrong SHI Lin | 2020 | Journal of Thermal Science2020，29，5： | 1 |
| 3 | Recommendations for control and prevention of infections for pediatric orthopedics during the epidemic period of COVID-19显示文摘The outbreak of Coronavirus Disease 2019(COVID-19)caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)emerged and spread rapidly throughout the world.As of February 29,2020,79389 cases of COVID-19 have been reported,and the outbreak is linked to 2838 deaths.The population is generally susceptible to the disease,and differences in incubation periods after infection exist among individuals.These two aspects of COVID-19 pose significant challenges to pediatric orthopedic diagnosis and treatment.As a dedicated center for managing pediatric cases of SARS-CoV-2 in Shanghai,our hospital has mobilized all branches and departments to undertake joint actions for scientific prevention and control,precise countermeasure and comprehensive anti-epidemic efforts.Combined with our experience,we have consulted the relevant national regulations and the latest research advances and have formulated the prevention and control measures of SARS-CoV-2 infection,including outpatient,emergency,inpatient and surgical cares,for clinical practices of pediatric orthopedics according to the physicochemical properties of SARS-CoV-2.It may serve as practical references and recommendations for managing SARS-CoV-2 infection in other pediatric specialties and in other hospitals. | Chunxing Wu Zhiqiang Zhang Yueqiang Mo Dahui Wang Bo Ning Ping Xu Jun Song Xinhong Pei Xiaoyan Ni Yiming Zheng Tian Xia Yanhui Jing Wanlin Sun Junrong Meng Chuang Qian | 2020 | World Journal of Pediatric Surgery2020，3，1： | 0 |
