The use of territories in border areas is sensitive, unique, and ecologically fragile. A scientific understanding of the transformation of the national territorial space and its ecological and environmental responses is crucial for optimizing spatial patterns and promoting sustainable utilization. This study focused on 45 cities in the land border areas of China and employed techniques such as the land transfer matrix, Theil index, and ecological environment index to explore the spatiotemporal evolution process and eco-environmental effects of territorial space from three dimensions: spatial pattern, structural transformation, and ecological response. The results show that:(1) During the study period, there was an increasing trend in living and production space, along with a decrease in ecological space, and a significant pattern of "one belt, three districts, and multipoints" emerged.(2) In the urbanization process, population growth and industrial agglomeration have led to the transformation and conflict of territorial spaces, with the conversion of ecological spaces into production spaces being the primary form of land-use transformation. Rapid development has resulted in spatial differentiation of the territorial space between regions.(3) During this period, the ecological quality in China's border areas deteriorated, yet the distribution pattern of ecological space remained stable, exhibiting a “high value in the southeast, low value in the northwest” pattern.(4) Improvements and degradation of the ecology coexist in different border areas;transforming agricultural production space into green and potential ecological spaces has positively contributed to enhancing ecological quality. In contrast, converting green ecological space into potential ecological space, agricultural production space, and aquatic ecological space has become a key factor in ecological degradation. Therefore, the border areas of China should utilize national preferential policies and strategies, recognize the vast and varied expanse of

An observation-based perspective of winter haze days in four major polluted regions of China

National Science Review 2019年第3期6卷 515-523页

作者： Lu Mao Run Liu wenhui liao Xuemei Wang Min Shao Shaw Chen Liu Yuanhang Zhang State Key Joint Laboratory of Environmental Simulation and Pollution Control Beijing Innovation Center for Engineering Science and Advanced Technology College of Environmental Sciences and Engineering Peking University Institute for Environmental and Climate Research Jinan University Guangdong University of Finance

An observation-based approach is used to examine key characteristics of winter haze days in four major polluted regions in China. Major findings in this study are: first, there was no significant trend in the number of winter haze days in most provinces and districts in eastern China from 1973 to 2012, contrary to the 2.5-fold increase in the emissions of particulate matter and its precursors(PM emissions) in the same period of time. Second, meteorological and climate conditions rather than PM emissions are in control of the interannual variabilities and trends of winter haze days. These interannual variabilities(ranging from 24 to 125%) pose a substantial masking effect that must be overcome by any control of PM emissions before its impact becomes statistically detectable. Finally, we find that global warming may have contributed significantly to the trend of winter haze days in eastern China.

Bacterial cellulose(BC)is an exopolysaccharide with unique properties that has been applied in various fields.However,the dense and intertwined nature of BC fibers limits its use in certain applications,including 3D printing scaffolds for bone regeneration.In this work,a controllable BC-based bio-ink for 3D printing was successfully prepared by modifying the neat BC through maleic acid(MA)treatment,aiming to promote bone tissue regeneration.To achieve homogeneous BC dispersions while preserving its crystalline and chemical properties,BC was modified by MA solution(60%,w/V)with solid-liquid ratio from 1꞉5 to 1꞉50(w/V)to obtain MA-BC dispersions.The analysis results from microstructure,chemical group,crystallinity,and wettability indicated that the BC/MA solution with ratio of 1꞉30 demonstrated the best pre-treatment performance to obtain MA-BC.Subsequently,by combining MA-BC with gelatin,we successfully formulated MA-BC-GEL gels with favorable rheological properties and compression modulus,which can be used as promising bio-inks for 3D bioprinting applications.In vitro tests demonstrated 1꞉30 MA-BC possessed excellent biocompatibility,a significant ability to express the alkaline phosphatase gene and osteogenic-related genes,and facilitated the formation of mineralized nodules.The utilization of this novel bio-ink in scaffold preparation for bone regeneration highlights the promising application of modified BC in bone tissue engineering field.

咸丰初年以后,新疆地区遭遇协饷欠解所致的财政困局。清廷中枢、陕甘总督与新疆各城官员尝试在开源、节流方面进行变通,但各项权宜之计所获有限,无法填补巨额支出缺口。新疆地区固然存在财政基础薄弱、开源潜力有限、邻近区域财政拮据等客观问题,但造成财政困境的深层原因是,清廷在新疆地区实行军府制下的多元管理模式,已无法应对近代中国面临的挑战。囿于“守中治边”的传统治边观念与以关内制衡关外的管控旧制,清廷与各省对解决新疆协饷欠解问题态度敷衍,最终酿成了严重的边疆危机。

嘉庆时期,在全国财政日趋支绌的背景下,作为协饷体系重要组成部分的新疆协饷在运作方面受到了一定的冲击。围绕如何节省新疆的协饷支出,清朝廷与甘肃、新疆高级官员展开了多次讨论。就结果而言,除岁需协济规模稍有增加外,新疆地区的协饷运作前后变动不大,基本以延续旧制为完结。与此同时,新疆地区在财政层面无法自给的内在限制与脆弱性开始显现,且始终没有获得解决或者纾解,为此后道光年间"回疆"地区的边防与治理危机埋下了伏笔。

Fluorescence lifetime imaging can reveal the high-resolution structure of various biophysical and chemical parameters in a microenvironment quantitatively.However,the depth of imaging is generally limited to hundreds of micrometers due to aberration and light scattering in biological tissues.This paper introduces an iterative multi-photon adaptive compensation technique(IMPACT)into a two-photon fluorescence lifetime microscopy system to successfully overcome aberrations and multiple scattering problems in deep tissues.It shows that 400 correction modes can be achieved within 5 min,which was mainly limited by the frame rate of a spatial light modulator.This system was used for high-resolution imaging of mice brain tissue and live zebrafish,further verifying its superior performance in imaging quality and photon accumulation speed.

Rydberg atoms-based electric field sensing has developed rapidly over the past decade.A variety of theoretical proposals and experiment configurations are suggested and realized to improve the measurement metrics,such as intensity sensitivity,bandwidth,phase,and accuracy.The Stark effect and electromagnetically induced transparency(EIT)or electromagnetically induced absorption(EIA)are fundamental physics principles behind the stage.Furthermore,various techniques such as amplitude-or frequency-modulation,optical homodyne read-out,microwave superheterodyne and frequency conversion based on multi-wave mixing in atoms are utilized to push the metrics into higher levels.In this review,different technologies and the corresponding metrics they had achieved were presented,hoping to inspire more possibilities in the improvement of metrics of Rydberg atom-based electric field sensing and broadness of application scenarios.
