1An overview of the use of plastic-film mulching in China to increase crop yield and water-use efficiency显示文摘Since 1990,crop yields have stagnated in many parts of the world,posing a significant challenge to global food security[1].As such;innovative solutions are needed to increase the resource-use efficiency of cropping systems to produce more grains per unit area.Dongbao Sun Haigang Li Enli Wang Wenqing He Weiping Hao Changrong Yan Yuzhong Li Xurong Mei Yanqing Zhang Zhanxiang Sun Zhikuan Jia Huaiping Zhou Tinglu Fan Xucheng Zhang Qin Liu Fengju Wang Chaochun Zhang Jianbo Shen Qingsuo Wang Fusuo Zhang 2020National Science Review2020,7,10:19
2Three-dimensional inversion of borehole-surface electrical data based on quasi-analytical approximation显示文摘地上凿穿表面的 3D 倒置为复杂 geo 电的模型的电的数据仍然是在地球物理的探索的一个挑战性的问题。我们为 3D 倒置开发了一个节目到地上凿穿表面电的数据基于伪分析的近似(质量保证) 并且 re 加权调整结合坡度方法(RRCG ) 用视觉 Fortran 6.5 的算法。到向前当模特儿和 Frechet 衍生物计算的 QA 近似的申请戏剧性地加快计算。为理论模型的合成数据的试用计算证明程序快、高度精确。Wang Zhigang He Zhanxiang Liu Haiying 2006Applied Geophysics2006,3,3:5
3The application of the high-frequency electromagnetic sounding method in the exploration of underground thermal water显示文摘高周波的电磁的发出声音作为地来源是用自然的高周波的电磁的地的一个电磁的探索方法。它比直接当前的方法有更高的分辨率和更大的深度穿入并且为地热的精力探索是特别合适的并且低 -- 并且中间水平的地下水察觉。我们介绍为评估地热的水资源的高周波的电磁的发出声音的成功的应用。高频率电磁的系统(有到 1 Hz 的从 10 KHz 的一个频率范围的 MT-U5A ) 首先被使用从中国取样域数据。一个遥远的参考车站被用来保证取样的数据质量。我们然后执行 2D 倒置图象与电的方法数据处理。结果基本上显示地下的地热的水的空间分发并且提供有利线索给在这个区域发现表面下的地热的水的来源。Cao Hui He Lanfang He Zhanxiang Zhao Xiaoming 2006Applied Geophysics2006,3,4:4

5Construction of Ecological Green Space System in Yan'an City,China显示文摘Ecosystem of Yan'an City is being faced with serious problems such as increasing pressure of protecting ecological elements,and contradictions in utilization of ecological spaces.To enhance supervision over regional ecological resources,guide the orderly expansion of urban spaces,construct a stable eco-security pattern for sustainable development of the city,and create an urban environment favorable for living and working,this study follows the principles of 'ecology on the priority,landscape continuity,diversity,optimization of layout,and sustainability'.By analyzing distribution features of ecological resources in Yan'an City,considering rules of its urban space expansion,and studying the 'ring-wedge-network' spatial pattern of its ecological green spaces,this study is to build an ecological network with a complete spatial system,definite ecological zoning and characteristic landscapes in which ecological elements are protected comprehensively,ecological conservation,restoration and construction promoted simultaneously.HE Hongyun,LI Zhanxiang(Shaanxi Urban and Rural Planning and Designing Academy,Xi’an,Shaanxi 710032,China) 2012Journal of Landscape Research2012,4,7:1
63D Modeling and Born approximation inversion for the borehole surface electromagnetic method显示文摘我们在场地上凿穿表面的数字建模的一条 3D 途径电磁(BSEM ) 方法。电磁的反应在分层的媒介由垂直的线水流来源创造了的 3D 用 3D 积分方程方法被建模。当模特儿的结果与分析答案一致。BSEM 数据的出生的近似倒置也是的 3D 为水库描述进行了。倒置方法被一个合成水库模型验证。Wang Zhigang He Zhanxiang Wei Wenbo 2007Applied Geophysics2007,4,2:1
7Modeling of 3D MCSEM and sensitivity analysis显示文摘He Zhanxiang Wang Zhigang Yu Gang 2007PIERS Online2007,3,5:1
8Calculation of Well-ground Electromagnetic Field Responses in Horizontally Layered Media显示文摘Cao Hui Wang Xuben He Zhanxiang Mao Lifeng Lv Dongwei 2012石油地球物理勘探2012,47,A02:0
9Effects of different LED light colors on growth performance and harmful gas emission of broilers breeding in a digital rearing chamber显示文摘Refined management is an inevitable trend in the development of livestock husbandry.Accurate acquisition of breeding environment parameters is beneficial to improve breeding efficiency while reducing environmental pollution.Light is an important breeding environmental factor during broiler breeding.In this study,a short-term broiler breeding experiment was conducted with different light color illumination environments in a digital breeding chamber under lab conditions.According to experimental results,the Red Light(RL)group was conducive to the growth of broilers at 30 d of age with low NH3 emission concentration;the Green Light(GL)group inhibited the broiler growth;the Yellow Light(YL)group showed the highest average emission concentration of NH3 and lowest daily average emission concentration of CO_(2).According to the analysis of moisture content,pH value,and C/N in the broiler manure,it can be concluded that the physical and chemical properties of broiler defecation quantities were different under various light color illuminations,resulting in the difference in broiler growth conditions and harmful gas emissions.The study results could provide a research basis and ideas of reference to establish a relationship between LED illumination information,broiler growth performance,and harmful gas emission.Dengfei Jie Zhanxiang Zhang Jincheng He Yafang Zhou Guangyou Zhu 2022International Journal of Agricultural and Biological Engineering2022,15,4:0
