Geomagnetic Energy Approach to Space Debris Deorbiting in a Low Earth Orbit
Published 2019-01-01“…The method can be applied to the regions of the LEO below 1000 km with different altitudes/inclinations and eccentricities, and with existent magnetorquer technology, only several days of preparation is required for about 104 m·kg mechanism-scale-debris-mass deorbiting, which can be used for deorbiting missions in debris-intensive areas (altitude≤1000 km); without consideration of external effects on the geomagnetic field distribution, it has the same deorbiting capability with that of the LEO below 1000 km when the altitude is over 1000 km. …”

The spatial relationship and influence mechanism of traditional villages and intangible cultural heritage: a case study of the upper reaches of the Yellow River Basin
Published 2025-02-01“…In contrast, ICH shows a “sparse south, dense center, and sparse north” distribution, with a lower degree of imbalance at the provincial level. (2) Although there is generally a high degree of spatial alignment between TVs and ICH, but at the provincial (or autonomous region) level, three types of regional displacements have been identified: high positive displacement, low positive displacement, and high negative displacement. (3) Factors such as altitude, river systems, temperature conditions, regional economy, accessibility, population density, urbanization rate, cultural characteristics, and funding policies significantly influence the spatial distribution of TVs and ICH. urbanization rate has a common influence and explanatory power on the spatial distribution of both TVsand ICH in the YRB, with altitude, financial policies, cultural history, and other factors having secondary influence and explanatory power.These factors are crucial in determining the pathways for their integrated development.…”

Temporal and Spatial Variation of Potential Evaporation and Its Influencing Factors in Pearl River Basin from 1980 to 2019
Published 2022-01-01“…Evaporation is an important link in the water cycle,and in-depth studies on the influence of various meteorological factors on evaporation changes are of great significance for climate change,ecological restoration,and utilization of water resources.In this study,the Penman-Monteith model modified by the Food and Agriculture Organization of the United Nations (FAO) is used to calculate the potential evaporation (ET<sub>0</sub>) in the Pearl River Basin from 1980 to 2019.The Mann-Kendall non-parametric test method and inverse distance weighting method are used to analyze the spatial and temporal distribution characteristics of the ET<sub>0</sub>,and the principal component analysis method is used to analyze the influencing factors.The results show that:① The average ET<sub>0</sub> of the Pearl River Basin is 1 145.8 mm,and the growth rate is 1.37mm/a,which shows an increasing trend.In terms of four seasons,the growth rate increases in spring (0.56 mm/a),autumn (0.4 mm/a),and winter (0.44 mm/a) but decreases in summer (-0.03 mm/a).② In terms of spatial distribution,the annual average ET<sub>0</sub> of the Pearl River Basin is high in the east,west,and south but low in the middle andnorth.The distribution of ET<sub>0 </sub>in summer,autumn,and winter is similar.However,the distribution of ET<sub>0</sub> in spring is opposite to that in summer,autumn,and winter.③ Temperature,average water vapor pressure,and altitude are the leading factors of ET<sub>0</sub> changes.Factors such as temperature,average water vapor pressure,sunshine duration,and wind speed make positive contributions to ET<sub>0</sub>,while altitude,latitude,and relative humidity make negative contributions to ET<sub>0</sub> changes.…”
