| 1 | Progress on design and related R&D activities for the water-cooled breeder blanket for CFETR显示文摘The water-cooled ceramic breeder (WCCB) blanket is one of the blanket candidates for Chinese fusion engineering testing reactor (CFETR) and is being developed at the Institute of Plasma Physics, Chinese Academy of Sciences (ASIPP). This paper reviews design and evolution of the WCCB blanket for CFETR, and presents a new WCCB blanket design according to the latest CFETR core parameters (major and minor radii are R = 7.2 m and a = 2.2 m, respectively) and missions. This new design is expected to satisfy multiple CFETR operation modes of 0.2, 0.5, 1.0, and 1.5 GW fusion power and achieve tritium self-sufficiency. The feasibility of the updated blanket design is evaluated from the aspects of neutronics and thermo-hydraulics. Furthermore, the research and development (R&D) activities supporting to the WCCB blanket for CFETR are reported, including the design code, the water loop experiments, the pebble bed modeling and experiments, and the components fabrication technology. | Songlin Liu Xiaoman Cheng Xuebin Ma Lei Chen Kecheng Jiang Xia Li Hui Bao Jichao Wang Wanjing Wang Changhong Peng Peng Lu Min Li Kai Huang | 2019 | Theoretical & Applied Mechanics Letters2019，9，3： | 6 |
| 2 | Low-complexity method for DOA estimation based on ESPRIT显示文摘A low-complexity method for direction of arrival(DOA) estimation based on estimation signal parameters via rotational invariance technique(ESPRIT) is proposed.Instead of using the cross-correlation vectors in multistage Wiener filter(MSWF),the orthogonal residual vectors obtained in conjugate gradient(CG) method span the signal subspace used by ESPRIT.The computational complexity of the proposed method is significantly reduced,since the signal subspace estimation mainly needs two matrixvector complex multiplications at the iteration of data level.Furthermore,the prior training data are not needed in the proposed method.To overcome performance degradation at low signal to noise ratio(SNR),the expanded signal subspace spanned by more basis vectors is used and simultaneously renders ESPRIT yield redundant DOAs,which can be excluded by performing ESPRIT once more using the unexpanded signal subspace.Compared with the traditional ESPRIT methods by MSWF and eigenvalue decomposition(EVD),numerical results demonstrate the satisfactory performance of the proposed method. | Xuebin Zhuang Xiaowei Cui Mingquan Lu Zhenming Feng | 2010 | Journal of Systems Engineering and Electronics2010，21，5： | 6 |
| 3 | Potential applications of porous organic polymers as adsorbent for the adsorption of volatile organic compounds显示文摘Volatile organic compounds(VOCs)with high toxicity and carcinogenicity are emitted from kinds of industries,which endanger human health and the environment.Adsorption is a promising method for the treatment of VOCs due to its low cost and high efficiency.In recent years,activated carbons,zeolites,and mesoporous materials are widely used to remove VOCs because of their high specific surface area and abundant porosity.However,the hydrophilic nature and low desorption rate of those materials limit their commercial application.Furthermore,the adsorption capacities of VOCs still need to be improved.Porous organic polymers(POPs)with extremely high porosity,structural diversity,and hydrophobic have been considered as one of the most promising candidates for VOCs adsorption.This review generalized the superiority of POPs for VOCs adsorption compared to other porous materials and summarized the studies of VOCs adsorption on different types of POPs.Moreover,the mechanism of competitive adsorption between water and VOCs on the POPs was discussed.Finally,a concise outlook for utilizing POPs for VOCs adsorption was discussed,noting areas in which further work is needed to develop the next-generation POPs for practical applications. | Shuangchun Lu Qingling Liu Rui Han Miao Guo Jiaqi Shi Chunfeng Song Na Ji Xuebin Lu Degang Ma | 2021 | Journal of Environmental Sciences2021，33，7： | 4 |
| 4 | Numerically stable method of signal subspace estimation based on multistage Wiener filter显示文摘In this paper,a numerically stable method of signal subspace estimation based on Householder multistage Wiener filter(HMSWF) is proposed.Numerical stability of the method lies on the fact that the Householder matrix in HMSWF ensures the unitary blocking operation and significantly strengthens the orthogonality of basis vectors,especially in the finite-precision implementation.In the following,we analyze the numerical stability of HMSWF and MSWF based on the correlation subtractive structure(CSS-MSWF) by establishing the equivalence between the forward recursion of MSWF and the Arnoldi algorithm in numerical linear algebra.Besides,the equivalence between HMSWF and the Householder QR decomposition(QRD) on the Krylov matrix underlying in MSWF is directly established.Based on the relationship,two theoretical upper bounds of the orthogonality error of basis vectors in signal subspace are obtained and it is demonstrated that the orthogonality of basis vectors based on HMSWF is perfectly preserved by the numerically well-behaved Householder matrix,and the corresponding signal subspace estimation is much more numerically stable than that based on CSS-MSWF.Simulations show the numerical stability of the proposed method of signal subspace estimation by HMSWF. | ZHUANG XueBin CUI XiaoWei LU MingQuan FENG ZhenMing | 2010 | Science China(Information Sciences)2010，53，12： | 4 |
| 5 | Characteristics and distribution patterns of reef complexes on the carbonate platform margin in deep water areas:the western South China Sea显示文摘As a potential oil and gas reservoir,reef complexes have been a research focus from petroleum geologists for a long time.There are favorable conditions for the development of reef complexes in the South China Sea; however,their internal structures,evolution and distribution are still poorly understood.Based on 2D and 3D seismic data,the internal structures and evolution patterns of the reef complexes on the carbonate platform margin in the deep water areas over the western South China Sea were studied in detail.The result shows that two types of reef complexes,i.e.,fault controlling platform margin reef complexes and ramp reef complexes have been developed in the study area.The reef complexes have independent or continuous mound or lenticular seismic reflections,with three internal structures(i.e.,aggrading,prograding and retrograding structures).There are different growth rates during the evolution of the reef complexes,resulting in the formation of catch-up reefs,keep-up reefs and quick step reefs.The study also reveals that different platform margin reef complexes have different internal structures and distributions,because of the different platform types.These results may be applied to the exploration and prediction of carbonate platform margin reef complexes in other areas that are similar to the study area. | CHEN Ping LI Xushen WANG Yahui LU Yongchao ZHONG Zehong CHEN Lei ZUO Qianmei MA Yiquan WANG Chao DU Xuebin | 2015 | Acta Oceanologica Sinica2015，34，10： | 3 |

| 8 | Evaluation of the toxicity of fluorine in Antarctic krill on soft tissues of Wistar rats显示文摘Antarctic krill are a potential food source for humans and animals, but krill are known to contain high levels of fluorine (F). In this study, we investigated the toxicity of F in Antarctic krill using Wistar rats. There were three experimental groups: The control group were fed a basal diet, the krill treatment group were fed the same basal diet mixed with krill powder (150 mg·kg-1 F), and the sodium fluoride (NaF) treatment group were fed the basal diet with added NaF (150 mg·kg-1 F). General toxicity indicators including body weight and food intake were measured during the experiment. After three months the rats were dissected and tissue samples were collected from the liver, kidney, spleen, brain, and testis. Morphological changes in the cells of these tissues were assessed using HE staining. There were no significant differences in the body weight, the food intake, or the viscera coefficients among the three groups. In both treatment groups some pathological changes were observed in all soft tissue samples except the testis, although there were fewer and less severe pathological changes in the krill treatment group than in the NaF treatment group. The results showed that the toxicity of F in Antarctic krill was lower than for an equivalent amount of F in NaF, but it was still toxic to rats consuming large quantities of krill. The findings of this study highlight the need for further investigation into potential F toxicity if krill is to be used for human consumption. | ZHANG Ling LU Xiaoqi WANG Zhangmin QIN Liqiang YUAN Linxi YIN Xuebin | 2013 | Advances in Polar Science2013，24，2： | 2 |
| 9 | New Seismic Attribute Technology for Predicting Dissolved Pore-Fracture of Deeply Buried Platform Margin Reef-Beach System in Northeast Sichuan Basin, China显示文摘The large reef complexes of the Upper Permian Changxing Formation, with a significant breakthrough for petroleum exploration, are an important target for petroleum exploration in the Yuanba area of the Sichuan Basin in SW China. The storage space types of reef complexes are dominated by the dissolved pore-fracture(DPF). However, using only single geophysical methods, it is difficult to predict effective distribution of DPF. Based on a combination of geological models and geophysics technology, this study proposes two new geophysical methods, including anisotropy coherence technique(ACT) and fracture intensity inversion(FII), to research the characteristics of DPF by faciescontrolling in Changxing Formation in Yuanba area. Two major findings are presented as follows:(1) the characteristics of DPF varying with facies are the result of different diagenetic and petrophysical property. The intensity of DPF decreases from reef and bioclastic bank to interbank sea and slope;(2) ACT can qualitatively identify the distribution of DPF with no-directional and dispersed distribution, while FII can quantitatively characterize the intensity of DPF development within various sedimentary facies. When integrated into the geological study, ACT and FII can provide an effective way to predict the distribution of DPF in similar geological settings and the predicted DPF have been supported by the historical well data. | Chao Wang Yongchao Lu Hongguang Huang Fengcun Xing Lei Chen Xuebin Du Zhanhong Liu Wenjun Zhang | 2015 | Journal of Earth Science2015，26，3： | 2 |

| 11 | Classification of rice seed variety using point cloud data combined with deep learning显示文摘Rice variety selection and quality inspection are key links in rice planting.Compared with two-dimensional images,three-dimensional information on rice seeds shows the appearance characteristics of rice seeds more comprehensively and accurately.This study proposed a rice variety classification method using three-dimensional point cloud data of the surface of rice seeds combined with a deep learning network to achieve the rapid and accurate identification of rice varieties.First,a point cloud collection platform was set up with a Raytrix light field camera as the core to collect three-dimensional point cloud data on the surface of rice seeds;then,the collected point cloud was filled,filtered and smoothed;after that,the point cloud segmentation is based on the RANSAC algorithm,and the point cloud downsampling is based on a combination of random sampling algorithm and voxel grid filtering algorithm.Finally,the processed point cloud was input to the improved PointNet network for feature extraction and species classification.The improved PointNet network added a cross-level feature connection structure,made full use of features at different levels,and better extracted the surface structure features of rice seeds.After testing,the improved PointNet model had an average classification accuracy of 89.4%for eight varieties of rice,which was 1.2%higher than that of the PointNet model.The method proposed in this study combined deep learning and point cloud data to achieve the efficient classification of rice varieties. | Yan Qian Qianjin Xu Yingying Yang Hu Lu Hua Li Xuebin Feng Wenqing Yin | 2021 | International Journal of Agricultural and Biological Engineering2021，14，5： | 1 |

| 16 | Wind and Photovoltaic Power Time Series Data Aggregation Method Based on an Ensemble Clustering and Markov Chain显示文摘Reducing the input wind and photovoltaic power time series data can improve the efficiency of time sequential simulations.In this paper,a wind and photovoltaic power time series data aggregation method based on an ensemble clustering and Markov chain(ECMC)is proposed.The ECMC method can effectively reduce redundant information in the data.First,the wind and photovoltaic power time series data were divided into scenarios,and ensemble clustering was used to cluster the divided scenarios.At the same time,the Davies-Bouldin Index(DBI)is adopted to select the optimal number of clusters.Then,according to the temporal correlation between wind and photovoltaic scenarios,the wind and photovoltaic clustering results are merged and reduced to form a set of combined typical day scenarios that can reflect the characteristics of historical data within the calculation period.Finally,based on the Markov Chain,the state transition probability matrix of various combined typical day scenarios is constructed,and the aggregation state sequence of random length is generated,and then,the combined typical day scenarios of wind and photovoltaic were sampled in a sequential one-way sequence according to the state sequence and then are built into a representative wind and photovoltaic power time series aggregation sequence.A provincial power grid was chosen as an example to compare the multiple evaluation indexes of different aggregation methods.The results show that the ECMC aggregation method improves the accuracy and efficiency of time sequential simulations. | Jingxin Jin Lin Ye Jiachen Li Yongning Zhao Peng Lu Weisheng Wang Xuebin Wang | 2022 | CSEE Journal of Power and Energy Systems2022，8，3： | 1 |
