针对可见光遥感图像中的机场跑道检测问题,提出了一种基于方向预判的局部Hough变换方法。通过频谱能量楔向采样,确定频谱图中对能量贡献起主导作用的系数分布角度范围与机场跑道的对应关系,得到跑道的方向预判结果;利用方向信息对Hough变换角度的取值范围进行压缩,通过局部Hough变换进行直线检测得到机场跑道。实验结果表明:该方法能够较好地消除复杂背景中地物的干扰,快速准确地检测出机场跑道。

Hyperlipidemia, type 2 diabetes mellitus, nonalcoholic fatty liver and many other metabolic disorder are frequently co-existing in patients. In addition, these diseases are closely related in pathophysiological settings. However, increasing of the disease incidence, lacking of comprehensive prevention and control measurements against the key pathology point concomitant occurrence with the pattem of the single disease, single target therapy, that is leading therapeutic strategy for these metabolic disorders in the setting of Western medicine （WM）. On the basis of the combination of the advantages of integrated Chinese medicine （CM） and WM, with unified understanding of such diseases, the new concept of glucolipid metabolic disease （GLMD） is introduced. In this new concept, disorders in glucose and lipid metabolism are recognized as the key trigger and major driving force for the progress of GLMD. The key points of pathology included dysfunction of neuronal-endocrine-immune system,insulin resistance, oxidative stress, inflammation and intestinal flora imbalance. In the core pathogenic perspective of CM, it can be explained as ＂Gan （Liver） Shi Shu Xie＂（dysfunction of Gan in metabolism and emotion regulation） that will lead to the occurence/production of endogenous dampness and phlegm, blood stasis and turbid. This leads to the new concept of ＂Liver-based regulatory system for metabolic homeostasis＂ to be introduced further. The comprehensive prevention and control strategy ＂Tiao Gan Qi Shu Hua Zhuo＂（modulating Gan, trigging key metabolic system to resolve pathogenic factors such as phlegm retention and dampness）. Its representative formula Fufang Zhenzhu Tiaozhi Capsule （复方贞术调脂胶囊） is innovated under such rationales. Comment for some commonly-used CM GLMD therapeutic drugs was presented. High-level evidence-based and epidemiological and mechanism studies should be carded out to further interpret and explain of the scientific connotation of GLMD.

乙酰丙酮铱是一种由过渡金属Ir与乙酰丙酮酸(acetylcaetonato)有机部分组成的过渡金属有机配合物,它是一种重要的绿光磷光材料,同时其也是多种铱系发光材料的组成部分.采用密度泛函理论(DFT)对Ir(acac)_(3)单体及其二聚物的基态几何结构进行了优化,在此基础上考察了它们的振动和红外光谱,并使用CIS方法对它们的激发态性质进行了理论研究.计算得到的单体和二聚物的吸收光谱均在紫外波段,单体的主要吸收峰有260 nm,350 nm,414 nm,二聚物的主要吸收峰有299 nm,353 nm,401 nm.计算得到了二者在乙腈CH_(3)CN溶液中的吸收光谱,与它们气相情况的结果相比,溶剂极性的影响使得电子吸收谱发生蓝移.计算结果表明Horst Kunkely和Arnd Vogler所得光谱中既含有单体的特征光谱,又含有二聚体的特征光谱,证明实验溶液中同时存在乙酰丙酮铱的低聚物,并且二者的组分比能被合理推算.最后,对多聚体的形成机理作了简单讨论.

A system impulse response with low sidelobes is critical in synthetic aperture radar（SAR） images because sidelobes contribute to noise and interfere with nearby scatterers. However,the conventional tricks of sidelobe suppression are unable to be exactly applied to the case of spaceborne sliding spotlight SAR due to great azimuth shifts in both time and frequency domains. In this paper, an extended chirp scaling algorithm is presented for spaceborne sliding spotlight SAR data imaging. The proposed algorithm firstly uses the spectral analysis（SPECAN） technique to avoid the azimuth spectrum folding effect and then employs the chirp scaling（CS） algorithm to achieve data focusing, i.e., the so-called two-step approach. To suppress the sidelobe level, an efficient strategy for the azimuth spectral weighting which only involves matrix multiplications and short fast Fourier transformations（FFTs） is proposed, which is a post-process executed on the focused SAR image and particularly simple to be implemented. The SAR image processed by the proposed extended CS algorithm is very precise and perfectly phase-preserving. In the end, computer simulation results verify the analysis and confirm the validity of the proposed algorithm.
