Sunlight degrades polystyrene faster than expected（图）
Sunlight polystyrene faster expected
2019/10/22
New research published by scientists at the Woods Hole Oceanographic Institution shows that polystyrene, one of the world's most ubiquitous plastics, may degrade in decades or centuries when exposed t...
Study:Sunlight and the right microbes convert Arctic carbon into carbon dioxide（图）
Sunlight microbes convert Arctic carbon carbon dioxide
2017/10/25
Nearly half of the organic carbon stored in soil around the world is contained in Arctic permafrost, which has experienced rapid melting, and that organic material could be converted to greenhouse gas...
Retrieving the vertical distribution of stratospheric OClO from Odin/OSIRIS limb-scattered sunlight measurements
vertical distribution of stratospheric OClO Odin/OSIRIS limb-scattered sunlight measurement
2009/1/8
The first vertical profiles of stratospheric OClO retrieved from Odin/OSIRIS limb-scattered sunlight radiances are presented. The retrieval method is based on a two-step approach, using differential o...
Retrieval of stratospheric aerosol size information from OSIRIS limb scattered sunlight spectra
stratospheric aerosol size OSIRIS scattered sunlight spectra
2008/11/25
Recent work has shown that the retrieval of stratospheric aerosol vertical profiles is possible using limb scattered sunlight measurements at optical wavelengths. The aerosol number density profile is...
Accounting for the effect of horizontal gradients in limb measurements of scattered sunlight
horizontal gradient scattered sunlight limb measurement
2008/11/11
Limb measurements provided by the SCanning Imaging Absorption spectrometer for Atmospheric CHartographY (SCIAMACHY) on the ENVISAT satellite allow retrieving stratospheric profiles of various trace ga...
建研科技开发的日照分析软件SunLight通过测试验证
2008/1/10
建筑日照是建筑环境重要的组成部分之一，由于国内相关软件技术发展的滞后，一些设计单位仍采用传统方法或直接依照规范推荐的日照间距进行设计，造成较大误差。近年来，随着公众对于日照问题的日益关注，新规范对住宅建筑日照标准有了更严格的强制性规定。有关日照的分析、检测及控制，涉及较为复杂的技术问题，原有的手工计算模式已无法适应实际设计应用的需求，利用计算机技术对建筑日照进行分析与辅助决策已成为城市规划设计...
7 March 2007，Large asteroids rotate at a range of different speeds, roughly following a bell-shaped "Gaussian" distribution in which most rotate at a speed close to some average, with only a small pro...

Effects of sunlight hydroxyl radical dissolved organic matter: Bacterial growth efficiency production of carboxylic acids other substrates
2014/5/19
This study examines the importance of several possible mechanisms causing sunlight-mediated changes in the amounts of bacterial utilization and biomass growth on dissolved organic matter (DOM) from al...
Photochemical Reactions of a-Terpinene and Acenaphthene under Concentrated Sunlight
Photodehydrogenation solar irradiation hydrogen abstraction benzophenone a-terpinene acenaphthene
2010/4/21
a-Terpinene was successfully dehydrogenated to p-cymene in photocatalytic reaction with benzophenone and cupric ions under 40 suns concentrated sunlight irradiation, proving that photodehydrogenation ...
