| 1 | Tectonic implications of Late Paleozoic stratigraphic distribution in Northeast China and adjacent region显示文摘An analysis of the distribution of the Late Paleozoic strata on Northeast China and adjacent region reveals a zonal pattern of the distribution around the core of the Jiamusi-Mongolia Block.The main part of Late Paleozoic marine strata in this area is considered the continental margin deposits of the Jia-musi-Mongolia Block by analyzing the stratigraphic contact relationship,lithofacies,etc.The results are exhibited in a series of tectonic paleogeographic maps.This presents an important proof for the foundation of the Jiamusi-Mongolia Block,and confines the forming time of Jiamusi-Mongolia Block to the Late Silurian. | ChengWen Wang YueWu Sun Ning Li GuoWei Zhao XiaoQin Ma | 2009 | Science China Earth Sciences2009，52，5： | 36 |
| 2 | A Spore-Pollen Assemblage from the Damoguaihe Formation in the Tamutsag Basin, Mongolia and Its Geological Implication显示文摘Based on the palynological data from Well Ta-19-36 and Well Ta-19-37 in the Ta'nan Sag, and Well Ta-22-1 and Well Ta-21-1 in the Bayin Gobi Sag, a spore-pollen assemblage from the Damoguaihe Formation is named as Cicatricosisporites minutaestriatus- Aequitriradites spinulosus-Protopinus sp. assemblage in the Tamutsag Basin, Mongolia. The assemblage is characterized by abundant gymnosperm pollen and diverse fern spores, counted 46.35%–65.57% and 34.43%–52.58% in percentage respectively. Among the gymnosperm pollen, Pinuspollenites sp.(2.66%–16.94%), Protopinus sp.(0–11.38%) and Protopicea sp.(0–10.81%) are dominant; and Alisporites sp., Cerebropollenites sp., Podocarpidites sp., and Abietineaepollenites sp. are common. Some important elements, such as Chasmatosporites sp., Callialasporites prominulus, Parvisaccites sp., Parcisporites sp., Jiaohepollis cf. annulatus, J. bellus, J. verus, Polycingulatisporites sp., Schizaeoisporites certus, Classopollis annulatus are seen. Within the fern spores, Osmundacidites wellamanii(0.85%–4.93%), Appendicisporites sp.(0–4.45%), Baculatisporites comaumensis(0.80%–2.87%), Cicatricosisporites sp.(0.51%–2.66%), C. minor(0–2.14%), Foraminisporis asymmetricus(0–2.40%), Aequitriradites sp.(0– 2.19%) and Cyathidites minor(0–2.13%) are dominant; and some specie of Densoisporites, Cooksonites, Impardecispora, Pilosisporites, Schizaeosprites, Fixisporites, Leptolepidites, Trilobosporites, Kuylisporites, Klukisporites, Hsuisporites, Couperisporites, Maculatisporites are seen. The angiosperm pollen are rare in the assemblage, characterized by Clavatipollenites sp.(0–0.80%) and Songipollis sp.(0–0.27%). The geological age of the Damoguaihe Formation is assigned to Hauterivian – Barremian of Early Cretaceous according to the palynological data, due to the fact that there existed a lot of diverse spores of the family Schizaeaceae and prosperous gymnosperm saccat pollen which the corpus and sacci are differentiated completely, and the presence of early angiosperm pollen of Clavatipollenites. However, the zircon U-Pb isotopic dating of the volcanic rocks in the Nantun Formation indicated that the overlying strata of the Nantun Formation, i.e. the Damoguaihe Formation must be younger than 127.0±2.0–137.9±1.5 Ma. This is consistent with the palynological data. Furthermore, the vegetation reconstructed on the palynological data of the Damoguaihe Formation is conifer forest with shrubs and grassland, belonging to the semi-humid or humid middle to south subtropical climate. Moreover, three new species, namely Biretisporites punctatus sp. nov., Chasmatosporites reticulates sp. nov. and Concentrisporites contractus sp. nov. are described here. | WANG Liyan WAN Chuanbiao SUN Yuewu | 2014 | Acta Geologica Sinica(English Edition)2014，88，1： | 12 |
| 3 | Study on the thermal protection performance of superalloy honeycomb panels in high-speed thermal shock environments显示文摘The thermal protection performance of superalloy honeycomb structure in high-temperature environments are important for thermal protection design of high-speed aircrafts. By using a self-developed transient aerodynamic thermal simulation system, the thermal protection performance of superalloy honeycomb panel was tested in this paper at different transient heating rates ranging from5℃/s to 30℃/s, with the maximum instantaneous temperature reaching 950℃.Furthermore, the thermal protection performance of superalloy honeycomb structure under simulated thermal environments was computed for different high heating rates by using 3D finite element method, and a comparison between calculational and experimental results was carried out. The results of this research provide an important reference for the design of thermal protection systems comprising superalloy honeycomb panel. | Dafang Wu Anfeng Zhou Liming Zheng Bing Pan Yuewu Wang | 2014 | Theoretical & Applied Mechanics Letters2014，4，2： | 6 |
| 4 | Model-Based Degree Estimation of Unbalance and Misalignment in Flexible Coupling-rotor System显示文摘The condition of rotor system must be assessed in order to develop condition-based maintenance for rotating machinery. It is determined by multiple variables such as unbalance degree,misalignment degree,the amount of bending deformation of the shaft,occurrence of shaft crack of rotor system and so on. The estimation of the degrees of unbalance and misalignment in flexible coupling-rotor system is discussed. The model-based approach is employed to solve this problem. The models of the equivalent external loads for unbalance and misalignment are derived and analyzed. Then,the degrees of unbalance and misalignment are estimated by analyzing the components of the equivalent external loads of which the frequencies are equal to the 1 and 2 times running frequency respectively. The equivalent external loads are calculated according to the dynamic equation of the original rotor system and the differences between the dynamical responses in normal case and the vibrations when the degree of unbalance or misalignment or both changes. The denoise method based on bandpass filter is used to decrease the effect of noise on the estimation accuracy. The numerical examples are given to show that the proposed approach can estimate the degrees of unbalance and misalignment of the flexible coupling-rotor system accurately. | LI Changyou XU Minqiang GUO Song WANG Yuewu WANG Rixin | 2009 | Chinese Journal of Mechanical Engineering2009，22，4： | 5 |
| 5 | Stratigraphic framework of late Paleozoic in northeastern China显示文摘Late Paleozoic strata in northeastern China are distributed in a zonal pattern around the old-land on the Jiamusi-Mongolia Block.They are composed of active deposits in the regular distributed tectonic lithofacies zones.This indicates that the late Paleozoic strata belong to continental margin deposits.According to the strong conformability of the sedimentary strata in the same continental margin and distinct differences among the three continental margins,three stratigraphical regions of the Jiamusi-Mongolia Stratigraphical Province are recognized along the northern,southern and eastern margins of the Jiamusi-Mongolia Block,named respectively as Xing'an Stratigraphical Region,Inner Mongolia grass--Songhua River Stratigraphical Region and Baoqing--Hunchun Stratigraphical Region.Due to the characteristics of continental margin deposits and active sediments,the strata can be correlated on the level of formation by the methods of analysing the rock association in the same stratigraphic region.Therefore,some revisions of the lithological formations of the late Paleozoic strata in northeastern China have been made,and a new chart of lithostratigraphic correlation has been proposed.Furthermore,the present stratigraphic framework is setting on the International Stratigraphic Chart on the level of stage,after comprehensive researches to lithostratigraphy,biostratigraphy and chronostratigraphy,especially the conodont biostratigraphy and isotopic ages of volcanic rocks obtained in recent years. | WANG Chengwen LI Ning SUN Yuewu ZONG Pu ZHAO Guowei LIU Hui MA Xiaoqin | 2013 | Global Geology2013，16，1： | 4 |

| 16 | Elucidate long-term changes of ozone in Shanghai based on an integrated machine learning method显示文摘Surface ozone(O_(3))is influenced by regional background and local photochemical formation under favorable meteorological conditions.Understanding the contribution of these factors to changes in O_(3)is crucial to address the issue of O_(3)pollution.In this study,we propose a novel integrated method that combines random forest,principal component analysis,and Shapley additive explanations to distinguish observed O_(3)into meteorologically affected ozone(O_(3_MET)),chemically formed from local emissions(O_(3_LC)),and regional background ozone(O_(3_RBG)).Applied to three typical stations in Shanghai during the warm season from 2013 to 2021,the results indicate that O_(3_RBG)in Shanghai was 48.8±0.3 ppb,accounting for 79.6%–89.4%at different sites,with an overall declining trend of 0.018 ppb/yr.O_(3_LC)at urban and regional sites ranged from 5.9–9.0 ppb and 8.9–14.6 ppb,respectively,which were significantly higher than the contributions of 2.5–7.4 ppb at an upwind background site.O_(3_MET)can be categorized into those affecting O_(3)photochemical generation and those changing O_(3)dispersion conditions,with absolute contributions to O_(3)ranging from 13.4–19.0 ppb and 13.1–13.7 ppb,respectively.We found that the O_(3)rebound in 2017,compared to 2013,was primarily influenced by unfavorable O_(3)dispersion conditions and unbalanced emission reductions;while the O_(3)decline in 2021,compared to 2017,was primarily influenced by overall favorable meteorological conditions and further emissions reduction.These findings highlight the challenge of understanding O_(3)change due to meteorology and regional background,emphasizing the need for systematic interpretation of the different components of O_(3). | Jin Xue Fangting Wang Kun Zhang Hehe Zhai Dan Jin Yusen Duan Elly Yaluk Yangjun Wang Ling Huang Yuewu Li Thomas Lei Qingyan Fu Joshua S.Fu Li Li | 2023 | Frontiers of Environmental Science & Engineering2023，17，11： | 0 |
| 17 | EVA Assessment,Discipline Constraints of CPC and SOEs’Inefficient Investment:Evidence From Listed Companies in Chinese A-Share Owned by Chinese Central Government显示文摘Based on the Richard Model in 2006,the author classify the Chinese Central Government-Owned Companies(CGOCs),which show the typical characteristics of State-Owned Enterprises(SOEs),by their state of investing into the sample of Over-Investment(OI)or Under-Investment(UI),then empirically testify how the assessment based on Economic Value-added(EVA)by Chinese State-owned Assets Supervision and Administration Commission(SASAC),and the Discipline Constraints(DCs)of the Communist Party of China(CPC)affect the state of Inefficient Investment(II).The author’s empirical results include those as following:(1)The EVA assessment has significant effect of restraining CGOCs’OI,but the effect is not significant for UI;(2)The DCs show no significant effect of suppressing OI,but significant effect of worsening UI;(3)As far as the moderating effect is concerned,DCs only in a small degree strengthen the function of EVA assessment for suppressing CGOCs’OI,but significantly weaken its function of relieving CGOCs’UI.Based on these empirical proofs,the author proposes that the emphasis of the EVA assessment and DCs should be synergistically shifted to CGOCs’UI,which has important institutional meanings especially under the background of macro-economic going down for a long time. | Yuewu Wang | 2021 | Economics World2021，9，2： | 0 |
| 18 | Supervised Deep Second-Order Covariance Hashing for Image Retrieval显示文摘Recently,deep hashing methods play a pivotal role in image retrieval tasks by combining advanced convolutional neural networks(CNNs)with efficient hashing.Meanwhile,second-order representations of deep convolutional activations have been established to effectively improve network performance in various computer vision applications.In this work,to obtain more compact hash codes,we propose a supervised deep second-order covariance hashing(SDSoCH)method by combining deep hashing with second-order statistic model.SDSoCH utilizes a powerful covariance pooling to model the second-order statistics of convolutional features,which is naturally integrated into the existing point-wise hashing network in an end-to-end manner.The embedded covariance pooling operation well captures the interaction of convolutional features and produces global feature representations with more discriminant capability,leading to the more informative hash codes.Extensive experiments conducted on two benchmarks demonstrate that the proposed SDSoCH outperforms its first-order counterparts and achieves superior retrieval performance. | Qian Wang YueWu Jianxin Zhang Hengbo Zhang Chao Che Lin Shan | 2020 | 国际计算机前沿大会会议论文集2020，，1： | 0 |
| 19 | Modeling,Oscillation Analysis and Distributed Stabilization Control of Autonomous PV-based Microgrids显示文摘Driven by rising energy demand and the goal of carbon neutrality,renewable energy generations(REGs),especially photovoltaic(PV)generations,are widely used in the urban power energy systems.While the intelligent control of microgrids(MG)brings economic and efficient operation,its potential stability problem cannot be ignored.To date,most of the research on modeling,analyzing and enhancing the stability of MG usually assume the DC-link as an ideal voltage source.However,this practice of ignoring the dynamics of DC-link may omit the latent oscillation phenomena of autonomous PV-based MG.First,this paper establishes a complete dynamic model of autonomous PV-based MG including PV panels and DC-link.Different from previous conclusions of idealizing DC-link dynamics,participation factor analysis finds the potential impact of DClink dynamics on system dynamic performance,and different influence factors including critical control parameters and nonlinear V-I output characteristic of PV array are considered to further reveal oscillation mechanisms.Second,based on the average consensus algorithm,a distributed stabilization controller with strong robustness is proposed to enhance stability of the PVbased MG,which does not affect the steady-state performance of the system.Finally,the correctness of all theoretical analysis and the effectiveness of the proposed controller are verified by time domain simulation and hardware-in-loop tests. | Zhuoli Zhao Jindian Xie Shaoqing Gong Xi Luo Yuewu Wang Chun Sing Lai Ping Yang Loi Lei Lai Josep M.Guerrero | 2023 | CSEE Journal of Power and Energy Systems2023，9，3： | 0 |
