| 1 | Development of a supercritical and an ultra-supercritical circulating fluidized bed boiler显示文摘The supercritical circulating fluidized bed(CFB)boiler,which combines the advantages of CFB combustion with low cost emission control and supercritical steam cycle with high efficiency of coal energy,is believed to be the future of CFB combustion technology.It is also of greatest importance for low rank coal utilization in China.Different from the supercritical pulverized coal boiler that has been developed more than 50 years,the supercritical CFB boiler is still a new one which requires further investigation.Without any precedentor engineering reference,Chinese researchers have con ducted fundamental research,development,design of the supercritical CFB boilers independently.The design theory and key technology for supercritical CFB boiler were proposed.Key components and novel structures were invented.The first 600 MWe supercritical CFB boiler and its auxiliaries were successfully developed and demonstrated in Baima Power Plant,Shenhua Group as well as the simulator,control technology,installation technology,commissioning technology,system integration and operation technology.Compared with the 460 MWe supercritical CFB in Poland,developed in the same period and the only other supercritical one of commercial running in the word beside Baima,the 600 MWe one in Baima has a better performance.Besides,supercritical CFB boilers of 350 MWe have been developed and widely commercialized in China.In this paper,the updated progress of 660 MWe ultra-supercritical CFB boilers under development is introduced. | Junfu LYU Hairui YANG Wen LING Li NIE Guangxi YUE Ruixin LI Ying CHEN Shilong WANG | 2019 | Frontiers in Energy2019，13，1： | 11 |

| 3 | Channel Capacity and Power Allocation of MIMO Visible Light Communication System显示文摘In this paper,the channel capacity of the multiple-input multiple-output(MIMO)visible light communication(VLC)system is investigated under the peak,average optical and electrical power constraints.Finding the channel capacity of MIMO VLC is shown to be a mixed integer programming problem.To address this open problem,we propose an inexact gradient projection method to find the channel capacity-achieving discrete input distribution and the channel capacity of MIMO VLC.Also we derive both upper and lower bounds of the capacity of MIMO VLC with the closed-form expressions.Furthermore,by considering practical discrete constellation inputs,we develop the optimal power allocation scheme to maximize transmission rate of MIMO VLC system.Simulation results show that more discrete points are needed to achieve the channel capacity as SNR increases.Both the upper and lower bounds of channel capacity are tight at low SNR region.In addition,comparing the equal power allocation,the proposed power allocation scheme can significantly increase the rate for the low-order modulation inputs. | Shuai Ma Ruixin Yang Guanjie Zhang Hang Li Wen Cao Linqiong Jia Yanyu Zhang Shiyin Li | 2023 | China Communications2023，20，2： | 0 |
| 4 | Some Remarks on Higgs Bundles over Compact Generalized Kahler Manifolds显示文摘In this paper,we first solve the Dirichlet problem forα-Hermite-Yang-Mills-Higgs equations on I_(±)-Higgs bundles over a compact generalized Kahler manifold.Then we prove that theα-semi-stability on I_(±)-Higgs bundles over closed generalized Kahler manifolds implies the existence of approximateα-Hermite-Yang-Mills-Higgs structure. | Ruixin WANG Wen WANG Songting YIN | 2021 | Journal of Mathematical Research with Applications2021，41，5： | 0 |
| 5 | An effector of Erysiphe necator translocates to chloroplasts and plasma membrane to suppress host immunity in grapevine显示文摘The powdery mildew(Erysiphe necator)is a prevalent pathogen hampering grapevine growth in the vineyard.An arsenal of candidate secreted effector proteins(CSEPs)was encoded in the E.necator genome,but it is largely unclear what role CSEPs plays during the E.necator infection.In the present study,we identified a secreted effector CSEP080 of E.necator,which was located in plant chloroplasts and plasma membrane.Transient expressing CSEP080 promotes plant photosynthesis and inhibits INF1-induced cell death in tobacco leaves.We found that CSEP080 was a necessary effector for the E.necator pathogenicity,which interacted with grapevine chloroplast protein VviB6f(cytochrome b6-f complex iron–sulfur subunit),affecting plant photosynthesis.Transient silencing VviB6f increased the plant hydrogen peroxide production,and the plant resistance to powdery mildew.In addition,CSEP080 manipulated the VviPE(pectinesterase)to promote pectin degradation.Our results demonstrated the molecular mechanisms that an effector of E.necator translocates to host chloroplasts and plasma membrane,which suppresses with the grapevine immunity system by targeting the chloroplast protein VviB6f to suppress hydrogen peroxide accumulation and manipulating VviPE to promote pectin degradation. | Bo Mu Zhaolin Teng Ruixin Tang Mengjiao Lu Jinfu Chen Xiangnan Xu Ying-Qiang Wen | 2023 | Horticulture Research2023，10，9： | 0 |
| 6 | Effect of spatial spectrum overlap on Fourier ptychographic microscopy显示文摘Fourier ptychographic microscopy(FPM)is a newly developed imaging technique which stands out by virtue of its high-resolution and wide FOV.It improves a microscope's imaging perfor-mance beyond the diffraction limit of the employed optical components by illuminating the sample with oblique waves of different incident angles,similar to the concept of synthetic aperture.We propose to use an objective lens with high-NA to generate oblique illuminating waves in FPM.We demonstrate utilizing an objective lens with higher NA to iluminate the sample leads to better resolution by simulations,in which a resolution of 0.28 pum is achieved by using a high-NA illuminating objective lens(NA=1.49)and a low-NA collecting objective lens(NA=0.2)in coherent imaging(λ=488 nm).We then deeply study FPM's exact relevance of convergence speed to spatial spectrum overlap in frequency domain.The simulation results show that an overlap of about 60%is the optimal choice to acquire a high-quality recovery(520*520 pixels)with about 2 min's computing time.In addition,we testify the robustness of the algorithm of FPM to additive noises and its suitability for phase objects,which further proves FPM's potential application in biomedical imaging. | Qiulan Liu Cuifang Kuang Yue Fang Peng Xiu Yicheng Li Ruixin Wen Xu Linu | 2017 | Journal of Innovative Optical Health Sciences2017，，2： | 0 |
