| 1 | Carbon Sequestration Effects of Shrublands in Three-North Shelterbelt Forest Region, China显示文摘三北方的防风林福雷斯特(TSF ) 节目,是六个关键林地节目之一并且有一个 73 年的构造时期,从 1978 ~ 2050。在这个区域的灌木的碳隐遁的定量分析为在中国理解森林和另外的陆上的生态系统的碳隐遁的全面功能是重要的。这研究在 1978 和 2008 基于遥感图象在 TSF 区域调查了 shrubland 的分发区域,并且从出版报纸与领域调查和以前的数据在联合计算了 shrubland 的碳密度。从 1978 ~ 2008 的碳隐遁数量和率在 TSF 区域为四个分区和灌木的不同类型被分析。结果揭示了那:1 ) 在学习区域和它的四个分区的 shrubland 的区域在过去的三十年期间增加了。为在 2008 的整个区域的 shrubland 的区域是为 25 恢复了年的 1.2 tation。实验在 Yanan 城市里在 Yangjuangou 集水被进行, Shaanxi 省,中国。二个邻近的斜坡为这研究被选择。六个样品地点是 spaced 到沿着山斜坡的脚趾斜坡的从顶点的每 3545 m,和每个样品地点包含了三个采样阴谋。土壤在表面土壤层( 010 厘米和 1020 厘米)的器官的碳和相关物理化学的性质基于土壤采样和实验室分析被测量,并且土壤二氧化碳(公司<潜水艇class=“ a-plus-plus ”> 2 )排出物和环境因素同时在一样的样品地点被测量。结果显示一般来说,一张更高的土壤碳股票被发现在里面吗? | LIU Wenhui ZHU Jiaojun JIA Quanquan ZHENG Xiao LI Junsheng LOU Xuedong HU Lile | 2014 | Chinese Geographical Science2014，24，4： | 11 |
| 2 | Arbitrary cylindrical vector beam generation enabled by polarization-selective Gouy phase shifter显示文摘Cylindrical vector beams(CVBs),which possess polarization distribution of rotational symmetry on the transverse plane,can be developed in many optical technologies.Conventional methods to generate CVBs contain redundant interferometers or need to switch among diverse elements,thus being inconvenient in applications containing multiple CVBs.Here we provide a passive polarization-selective device to substitute interferometers and simplify generation setup.It is accomplished by reversing topological charges of orbital angular momentum based on a polarization-selective Gouy phase.In the process,tunable input light is the only condition to generate a CVB with arbitrary topological charges.To cover both azimuthal and radial parameters of CVBs,we express the mapping between scalar Laguerre–Gaussian light on a basic Poincaré sphere and CVB on a high-order Poincaré sphere.The proposed device simplifies the generation of CVBs enormously and thus has potential in integrated devices for both quantum and classic optical experiments. | JUNLIANG JIA KEPENG ZHANG GUANGWEI HU MAPING HU TONG TONG QUANQUAN MU HONG GAO FULI LI CHENG-WEI QIU PEI ZHANG | 2021 | Photonics Research2021，9，6： | 4 |
