1High-aspect 3D two-photon polymerization structuring with widened objective working range (WOW-2PP)显示文摘We developed a novel two-photon polymerization(2PP)configuration for fabrication of high-aspect three-dimensional(3D)structures,with an overall height larger than working distance of the microscope objective used for laser beam focusing into a photosensitive material.This method is based on a modified optical 2PP setup,where a microscope objective(1003 high N.A.),immersion oil and cover glass can be moved together into the photosensitive material,resulting in an effective higher and wider objective working range(WOW-2PP).The proposed technique enables the fabrication of high-aspect structures with sub-micrometer process resolution.3D structures with a height of 7 mm are demonstrated,which could hardly be built with the conventional 2PP set-up due to refractive index mismatch and laser beam disturbances.Kotaro Obata Ayman El-Tamer Lothar Koch Ulf Hinze Boris N Chichkov 2013Light(Science & Applications)2013,2,1:7
2运用卫星数据和来自国家森林清查的野外数据进行全国森林变量估计显示文摘瑞典约有55%的土地面积被森林所覆盖。目前,瑞典的森林覆盖没有统一的和地理学上明晰的描述。现存的独立性数据源是Landsat TM和SPOT HRV卫星数据、地图蒙片(map mask)和森林清查样地。它们在一起,使森林变量(如材积和林分年龄)的计算机估计成为可能。这些估计的精确度在像素水平上是低的,但在林分水平上较高。在规划木材资源应如何加以利用或出于监测目的时,这类基于栅格的森林数据对政府来说是有帮助的。本文描述了以有效成本建立森林变量估计全国数据库的生成流程。我们在林分水平上评价了瑞典西南部某地森林变量估计的精确度。结果表明,总材积估计的整体均方根误差为33%,年龄估计的整体均方根误差为23%。Heather Reese Mats Nilsson Tina Granqvist Pahlén Olle Hagner Steve Joyce Ulf Tingelf Mikael Egberth Hkan Olsson 王胜 2003AMBIO-人类环境杂志2003,32,8:4

10DDT化合物和PCB在富营养和贫营养湖中的季节性变化及其与藻类生物量之关系显示文摘1996~1997期间,在一个富营养湖(湖E)和一个贫营养湖(湖O)中进行了富营养化和有机污染物(PCB,DDTs及γ-HCH)的交互作用研究,两湖的地貌形态和水化学相似。集水区的土壤样品表明两湖暴露于相似的大气条件下。与湖O相比湖E没有观测到生物稀释。湖E的沉积物(1.5倍)、表面沉积物(1.4倍)和河鲈(Perca fluviatilis)(2.4倍)的有机碳和脂质物质中的PCB水平较高,并且微粒的沉降流较大,沉积物捕集器和沉淀物表面PCB的水平也较高。湖E中PCB的大部分转运主要是靠浮游植物。DDD/DDE比值较高似乎与p,p’-DDT的高负载相关而非厌氧的原因。所记录的湖O深层沉积岩心的高DDD/DDE比值和sDDT的高水平以及在此期间沉积最多,大概是由于从集水区流入的前体DDT最高的缘故。Maria Sderstrm Kerstin Nylund Ulf Jrnberg Gran Lithner Gran Rosén Henrik Kylin 邵平 樊恩源 2000AMBIO-人类环境杂志2000,29,4:1
