	Screening for over 1000 organic micropollutants in surface water and sediments in the Liaohe River watershed 期刊论文 OAI收割 CHEMOSPHERE, 2015, 卷号: 138, 页码: 519-525 作者: Bu, Qingwei; Luo, Qian; Wang, Donghong; Rao, Kaifeng; Wang, Zijian 收藏 \| 浏览/下载：37/0 \| 提交时间：2016/03/11 Semi-quantification Screening analysis Source identification Watershed management Cluster analysis
	The application study on building materials with computer color quantification system (EI CONFERENCE) 会议论文 OAI收割 ICO20: Illumination, Radiation, and Color Technologies, August 21, 2005 - August 26, 2005, Changchun, China 作者: Yu H.; Li Z.; Li Z. 收藏 \| 浏览/下载：24/0 \| 提交时间：2013/03/25 The first impression of any building to a person is its exterior and decoration therefore at the same time and therefore the quality of decoration project shows the more important position in building project. A lot of projects produce quality problem because of the material color difference how to grasp and control the color change of building materials the color difference problem laying stone materials is also studied in this paper which exists universally at the common project and carry out color quantification and the solution scheme has been given using this system. and is often found at the high-grade decoration it has the very important meaning. According to the color theory a computer vision system used in color quantification measurement is established the standard illuminant A is selected as the light source. In order to realize the standardization of color evaluation the mutual conversion between RGB and XYZ color space is studied which is realized by the BP network. According to the colorimetry theory the computer program is compiled in order to establish the software system and realize the color quantitative appraisement in whole color gamut. LCH model is used at quantifying the color of building materials and LaV model is used at comparing the color change. If the wooden floor is selected and laid improperly during family fitment it is easy to present "flower face". The color also arises greater discrepancy using the laths of same tree. We can give the laying scheme using the color quantification system
