The parameters are: the terminal velocity of the wind, the mass loss rate of the donor, the effective temperature and the magnetic fields. These parameters influence significantly the improvement of the model of accretion. In spite of the variety of their observational properties, the corresponding magnetic field is around B ~ 10^12 G. This result can be constrained by the effects on stellar evolution. In addition, we have performed a segmentation in the parameter space of donors intended for several SG-HMXB listed in our sample set. The parameter space can be categorized into five regimes depending on the possibility of disk formation associated with accretion from the stellar wind. This can give a quantitative clarification of the observed variability and the properties of these objects. We show that, when these systems come into the direct accretion region, systems with corresponding parameters can emit X-rays.   动态FDG-PET成像中定量分析相关算法的研究 学位论文  OAI收割 工学博士, 中国科学院自动化研究所: 中国科学院研究生院, 2012 作者:  代晓倩 收藏  |  浏览/下载：140/0  |  提交时间：2015/09/02 动态PET  FDG  定量分析  参数估计  输入函数  Dynamic PET  FDG  quantitative analysis  parameter estimation  input function   Seed recalcitrance: a current assessment 期刊论文  OAI收割 ACTA BOTANICA SINICA, 2003, 卷号: 45, 期号: 6, 页码: 638-643 Song, SQ; Patricia, B; Pammenter, N; Ntuli, TM; Fu, JR 收藏  |  浏览/下载：23/0  |  提交时间：2012/07/16 desiccation-tolerance  desiccation-sensitivity  orthodox seed  recalcitrant seed  intermediate seed  influence factor and assessment parameter of desiccation tolerance  quantitative feature  critical water content  seed recalcitrance   Prediction of the thin-layer chromatographic retention of amino acids 期刊论文  OAI收割 jpc-journal of planar chromatography-modern tlc, 1998, 卷号: 11, 期号: 4, 页码: 300-304 作者:  Wang, YS;  Lin, LM;  Zhang, J 收藏  |  浏览/下载：17/0  |  提交时间：2015/11/09 TLC  amino acids  multi-parameter regression equation  quantitative structure-retention relationships (QSRRs)
