| 1 | 西双版纳热带森林挥发性有机物的观测研究显示文摘2002年7月中旬利用异戊二烯通量测定系统对云南西双版纳热带森林异戊二烯的排放通量进行了连续测量,同时对光合有效辐射(PAR)、气温、湿度、风等参数进行了观测.结果表明,热带地区人工橡胶林区域湿季异戊二烯的排放有明显的日变化规律,中午前后为一天中的最大值,异戊二烯排放通量的日平均值在0.85~0.24mgC/(m2(h)之间.对小时值和日平均值而言,异戊二烯的排放与PAR和气温的变化规律比较一致,但它对PAR比对气温更加敏感.不同的天气状况对异戊二烯的排放有非常明显的影响.橡胶林是一个单萜烯排放者,其单萜烯的排放速率明显依赖于PAR.橡胶林和热带雨林冠层上空异戊二烯和单萜烯的浓度也有明显的日变化规律,而且橡胶林区域的异戊二烯和单萜烯的浓度均明显高于热带雨林. | 白建辉 Bradly Baker Curtis Johnson 李庆军 王永峰 赵崇奖 Lee Klinger Alex Guenther Jim Greenberg | 2004 | 中国环境科学2004,24,2: | 9 |

| 6 | Effectiveness of a fixed-depth sensor deployed from a buoy to estimate water-column cyanobacterial biomass depends on wind speed显示文摘Water quality sondes have the advantage of containing multiple sensors,extended deployment times,high temporal resolution,and telecommunication with stakeholder accessible data portals.However,sondes that are part of buoy deployments often suffer from typically being fixed at one depth.Because water treatment plants are interested in water quality at a depth of the water intake and other stakeholders(ex.boaters and swimmers)are interested in the surface,we examined whether a fixed depth of approximately 1 m could cause over-or under-estimation of cyanobacterial biomass.We sampled the vertical distribution of cyanobacteria adjacent to a water quality sonde buoy in the western basin of Lake Erie during the summers of 2015–2017.A comparison of buoy cyanobacteria RFU(Relative Fluorescence Unit)at 1 m to cyanobacteria chlorophyll a(chla)measured throughout the water column showed occurrences when the buoy both under and overestimated the cyanobacteria chl a at specific depths.Largest differences between buoy measurements and at-depth grab samples occurred during low wind speeds(<4.5 m/sec)because low winds allowed cyanobacteria to accumulate at the surface above the buoy’s sonde.Higher wind speeds(>4.5 m/sec)resulted in better agreement between the buoy and at-depth measurements.Averaging wind speeds 12 hr before sample collection decreased the difference between the buoy and at-depth samples for high wind speeds but not low speeds.We suggest that sondes should be placed at a depth of interest for the appropriate stakeholder group or deploy sondes with the ability to sample at various depths. | Justin D.Chaffin Douglas D.Kane Alex Johnson | 2020 | Journal of Environmental Sciences2020,32,7: | 1 |

| 12 | 生活在爱因斯坦的世界中显示文摘在二十世纪初古典物理学出现危机的关键时刻,爱因斯坦是推动物理学革命思想的一面光辉旗帜。他独自发现了狭义相对论和广义相对论,从根本上改变了传统的绝对时空观念,将时空、物质和作用力通过对称性统一起来。从狭义相对论出发,他提出了质量和能量等价的公式,开辟了原子能的时代。从广义相对论和核能出发,他和一批科学家发展了宇宙构造和起源的模式,他提出的宇宙常数预示了产生排斥力的暗能量的存在。他和普兰克及玻尔一起是量子论的主要奠基人,他提出了集波动性和粒子性于一身的光量子学说,解释了光电效应,促进了量子波动力学的发现。他发展了原子论和统计力学,解释了从布朗运动、固体比热到受激辐射等一系列现象,他和玻色合作,建立了玻色-爱因斯坦量子统计理论,预见了玻色凝聚态的存在。他置疑量子力学提出的量子纠缠态,开辟了量子信息学的新领域。他在晚年致力于统一场论,虽然没有取得他预期的结果,但他提出的从高维几何局域对称性出发进行统一相互作用力的思想至今仍指导着基本相互作用大统一理论的发展方向,在他逝世后的半个世纪中,已经在弱电和强相互作用的统一中得到体现。在爱因斯坦的狭义相对论发表100用年之际,在纪念这位伟大的物理学家的同时,我们更当反思,爱因斯坦何以成为伟人? | Alex Johnson 尹宏毅 | 2005 | 英语文摘2005,0,6: | 0 |
