	The error analysis of automated biochemical analyzer (EI CONFERENCE) 会议论文 OAI收割 2011 International Conference on Computing, Information and Control, ICCIC 2011, September 17, 2011 - September 18, 2011, Wuhan, China Qinghai C.; Yihui W.; Haiwen L.; Peng H. 收藏 \| 浏览/下载：34/0 \| 提交时间：2013/03/25 In order to find out the relationships between the four error sources namely locating error optics system fluctuations sampling error and temperature fluctuations and the accuracy of the instrument we analyzed each relationship of them and found that the effect of locating error is so tiny that it can be ignored finally established the total error model and the model of the allowed noise of the optics system of the instrument. Analysis and the models may supply a reliable theory evidence for the improvement of the instrument and the designing of similar instruments. 2011 Springer-Verlag.

	Mechanism of STED microscopy and analysis of the factors affecting resolution (EI CONFERENCE) 会议论文 OAI收割 6th International Symposium on Precision Engineering Measurements and Instrumentation, August 8, 2010 - August 11, 2010, Hangzhou, China Yang P.; Ai H. 收藏 \| 浏览/下载：23/0 \| 提交时间：2013/03/25 Stimulated emission depletion (STED) microscopy exploits nonlinear saturable optical transition of fluorescent molecules allowed to overcome Abbe's diffraction-limit and provides diffraction-unlimited resolution in far-field optical microscopy. We elaborate the mechanism of STED and the conditions of depletion. The formula of STED microcopy resolution is deduced through effective point spread function (E-PSF). The STED system resolution is mainly dominated by the quality of the fluorescence depletion patterns in the focal plane. The depletion pattern is mainly affected by STED beam intensity polarization phase plate primary aberrations STED pulse shape pulse duration and delay time. In this paper we found related models and simulate the relationship between the depletion patterns and the parameters and put forward effective approach to enhance the system resolution. 2010 SPIE.
	Remote chlorophyll-a retrieval in eutrophic inland waters by concentration classification Taihu Lake case study 会议论文 OAI收割 International Conference on Earth Observation Data Processing and Analysis, ICEODPA,, Wuhan, China, December 28, 2008 - December 30,2008 Du, Cong; Wang, Shixin; Zhou, Yi; Yan, Fuli 收藏 \| 浏览/下载：33/0 \| 提交时间：2014/12/07 In order to improve the precision of phytoplankton chlorophyll-a (chla) concentration retrieval this study classified the data into two groups (the high and the low) by chla concentration with the threshold of 50gA&bullL-1. And then build the statistical models for each group. Particularly a modifying factor OSS/TSS was used to unmixing the spectra in the low model to improve the low relationship between spectral reflectance and chla concentrations. As a result the concentration classification model allowed estimation of chla with a root mean square error (RMSE) of 21.12gA&bullL-1 and the determination coefficient (R2) was 0.92 comparing with RMSE of chla estimation was 35.72gA&bullL-1 and R2=0.72 in the traditional model. It shows that concentration classification is a helpful method for accurate remote chla retrieval in eutrophic inland waters. 2008 SPIE.
	Selection rules for 4f2&rarr4f2 electric dipole transitions by considering mixing with 4f5d components of Pr3+ in SrAl12O19 (EI CONFERENCE) 会议论文 OAI收割作者: Wang X.-J.; Zhang J.-H. 收藏 \| 浏览/下载：20/0 \| 提交时间：2013/03/25 A set of selection rules is deduced for the 4f2 transitional levels that mix with explicit 4f5d components. Based on these selection rules the dipole-allowed transitions between the 4f2 crystal field levels are determined in Pr3+ doped SrAl12O19. Meanwhile the main 4f5d components mixed into 4f2 transitional levels are identified by determining the nonzero matrix elements of both the odd-rank crystal-field and the electric dipole operator. The selection rules have been applied to analyze the transitions from 1S0 and 3P0 to lower crystal field levels. 2006 Elsevier B.V. All rights reserved.
