| 1 | Climatic Warming and Humidification in the Arid Region of Northwest China: Multi-Scale Characteristics and Impacts on Ecological Vegetation显示文摘The climatic warming and humidification observed in the arid region of Northwest China(ARNC) and their impacts on the ecological environment have become an issue of concern. The associated multi-scale characteristics and environmental responses are currently poorly understood. Using data from satellite remote sensing, field observations, and the Coupled Model Intercomparison Project phase 6, this paper systematically analyzes the process and scale characteristics of the climatic warming and humidification in the ARNC and their impacts on ecological vegetation. The results show that not only have temperature and precipitation increased significantly in the ARNC over the past 60 years, but the increasing trend of precipitation is also obviously intensifying. The dryness index, which comprehensively considers the effects of precipitation and temperature, has clearly decreased, and the trend in humidification has increased. Spatially, the trend of temperature increase has occurred over the entire region, while 93.4% of the region has experienced an increase in precipitation, suggesting a spatially consistent climatic warming and humidification throughout the ARNC. Long-term trends and interannual changes in temperature and precipitation dominate the changes in climatic warming and humidification. Compared to interannual variations in temperature, the trend change of temperature contributes more to the overall temperature change. However, the contribution of interannual variations in precipitation is greater than that of the precipitation trend to the overall precipitation change. The current climatic warming and humidification generally promote the growth of ecological vegetation. Since the 1980 s,82.4% of the regional vegetation has thrived. The vegetation index has a significant positive correlation with precipitation and temperature. However, it responds more significantly to interannual precipitation variation, although the vegetation response varies significantly under different types of land use. The warming and humidification of the climate in the ARNC are probably related to intensifications of the westerly wind circulation and ascending air motions.They are expected to continue in the future, although the strength of the changes will probably be insufficient to significantly change the basic climate pattern in the ARNC. The results of this study provide helpful information for decision making related to China's 'Belt and Road' development strategies. | Qiang ZHANG Jinhu YANG Wei WANG Pengli MA Guoyang LU Xiaoyun LIU Haipeng YU Feng FANG | 2021 | Journal of Meteorological Research2021，35，1： | 19 |
| 2 | Analysis for retrieval and validation results of FY-3 Total Ozone Unit (TOU)显示文摘Retrieval experiment was made for global total column ozone using the first year measurements of Total Ozone Unit (TOU) on board the second generation polar orbiting meteorological satellite of China, FY-3/A. The retrieval results were analyzed and validated by comparison with AURA/OMI, Meteop/GOME-2 global ozone products and ground-based ozone measurement data. The qualititative comparisons over the globe especially over Antarctica and the Tibetan Plateau show that the spatial and temporal distribution characteristics are consistent with OMI and GOME-2 products. The quantitative comparisons with ground-based measurements and AURA/OMI ozone product were made over 74 stations, the TOU total ozone retrieval has a 3% rms relative error compared with AURA/OMI ozone product and 4.2% rms relative error with ground-based measurements. The maximum difference between satellite retrieval and ground-based measurements was found in the Antarctica ozone hole. The TOU global ozone product is operational and distributed to all users. | WANG WeiHe ZHANG XingYing AN XingQin ZHANG Yan HUANG FuXiang WANG YongMei WANG YingJian ZHANG ZhongMou LU JianGong FU LiPing JIANG Fang LIU GuoYang | 2010 | Chinese Science Bulletin2010，55，26： | 12 |

| 5 | The State-of-the-Art Review on Applications of Intrusive Sensing,Image Processing Techniques,and Machine Learning Methods in Pavement Monitoring and Analysis显示文摘In modern transportation,pavement is one of the most important civil infrastructures for the movement of vehicles and pedestrians.Pavement service quality and service life are of great importance for civil engineers as they directly affect the regular service for the users.Therefore,monitoring the health status of pavement before irreversible damage occurs is essential for timely maintenance,which in turn ensures public transportation safety.Many pavement damages can be detected and analyzed by monitoring the structure dynamic responses and evaluating road surface conditions.Advanced technologies can be employed for the collection and analysis of such data,including various intrusive sensing techniques,image processing techniques,and machine learning methods.This review summarizes the state-ofthe-art of these three technologies in pavement engineering in recent years and suggests possible developments for future pavement monitoring and analysis based on these approaches. | Yue Hou Qiuhan Li Chen Zhang Guoyang Lu Zhoujing Ye Yihan Chen Linbing Wang Dandan Cao | 2021 | Engineering2021，7，6： | 3 |
| 6 | A critical review of carbon materials engineered electrically conductive cement concrete and its potential applications显示文摘Carbon materials engineered electrically conductive cement concrete(ECCC)is typically prepared by directly adding carbon-based conductive filler into the cement matrix and then mixing cement with aggregates.With such a strategy,ECCC possesses a high conductivity and strain/stress sensitivity and thus can be used for snow and ice melting,ohmic heating,cathodic protection system,electromagnetic shielding,structural health monitoring,and traffic detection.This paper aims to provide a systematic review on the development and applications of ECCC,especially the progress made in the past decade(from 2012 to 2022).The composition and manufacture of ECCC are first introduced.Then,the electrical performance of ECCC and its potential applications are reviewed.Finally,the remaining challenges for future work are discussed. | Dong Lu Zhen Leng Guoyang Lu Daiyu Wang Yanlin Huo | 2023 | International Journal of Smart and Nano Materials2023，14，2： | 1 |
| 7 | Characterization of road surfacing aggregates based on their mineralogical fingerprint显示文摘To ensure the safety of infrastructure users,the long-term skid resistance is a crucial factor and is determined in large by the mineralogical and morphological characteristics of surfacing aggregate.Most studies have investigated these aggregate properties separately without considering the interrelation between one another.The objective of this study is to consider the morphological characteristics as well as the mineralogical fingerprint of aggregate to develop an innovative approach to optimize the aggregate selection process.The investigations are based on 11 different aggregate types with a broad range of mineralogy,commonly used in Germany.The long-term influence of polishing and wearing on the surface aggregate was simulated by means of the Aachen Polishing Machine and the MicroDeval test respectively.To evaluate the impact of these tests,the aggregate shape was characterized by means of an imaging system called Aggregate Image Measurement System while the skid resistance of aggregates was evaluated with the British Pendulum Test.The test results show that the quartz and calcite are the key crystals to determine the anti-wear resistance of aggregates.A correlation between the skid resistance,morphological properties and mineralogy is derived,which proves the mineralogical fingerprint technology is practical for characterization of aggregates used in pavement surface layers. | Dawei Wang Yulin He Chonghui Wang Zeyu Zhang Guoyang Lu Pengfei Liu Markus Oeser | 2022 | Journal of Traffic and Transportation Engineering(English Edition)2022，9，5： | 0 |
