SAR图像对地定位是解决SAR遥感信息在哪里的根本问题,它是遥感应用和处理的重要步骤。作者在分析现有几种SAR图像对地定位模型的基础上,根据SAR成像的严格几何关系导出SAR图像对地定位的严密共线方程模型。首先根据斜距图像的近地点斜距和远地点斜距推导中心投影等效焦距的计算公式,然后详细推导并给出斜距图像转化成严密中心投影图像时涉及的图像改化公式,最后根据实际星载SAR图像定位的精度对比,证明严密共线方程模型是可行的,而且其定位精度要明显优于传统的近似共线方程模型。

基于等效刚度的思想,通过设定层合板的属性参数模拟了加筋板结构的力学特性,提出了一种适用于不同截面形状以及布局形式的加筋板总体失稳分析的等效层合板建模方法。利用PATRAN/NASTRAN软件比较了反映实际壁板形状的高精度有限元模型与对应的赋有层合板属性的等效刚度简化模型。对于工程中常见形状的加强筋以及不同布局形式的壁板,2种模型的一阶线性失稳因子基本一致,从而验证了将等效层合板模型用于加筋壁板结构的稳定性分析可以满足工程精度要求,并显著提高了计算效率。

作者： Cong Xue Wei Hua chi Cai Li-Gang ding Zhi-Min Liu Xiao-Han Fan Yun-Zi Zhao Shu Zhang Cardiac Arrhythmia Center State Key Laboratory of Cardiovascular Disease Fuwai Hospital National Center for Cardiovascular Diseases Chinese Academy of Medical Sciences and Peking Union Medical College Beijing 100037 China

Background： Prolongation of the Tpeak-Tend （TpTe） interval as a measurement of transmural dispersion of repolarization （TDR） is an independent risk factor for chronic heart failure mortality, However, the cardiac resynchronization therapy＇s （CRT） effect on TDR is controversial. Therefore, this study aimed to evaluate CRTs acute and chronic effects on repolarization dispersion. Furthermore, we aimed to investigate the relationship between TpTe changes and ventricular arrbythmia. Methods： The study group consisted of 101 patients treated with CRT-defibrillator （CRT-D）. According to whether TpTe was shortened, patients were grouped at immediate and l-year follow-up after CRT, respectively. The echocardiogram index and ventricular arrhythmia were observed and compared in these subgroups. Results： For all patients, TpTe slightly increased immediately after CRT-D implantation, and then decreased at the l -year follow-up （from 107 ± 23 to 110 ± 21 rns within 24 h, to 94 ± 24 ms at 1-year follow-up, F 19.366, P 〈 0.001）. No significant difference in the left ventricular reverse remodeling and ventricular tachycardia/ventricular fibrillation （VT/VF） episodes between the TpTe immediately shortened and TpTe immediately nonshortened groups. However, patients in the TpTe at l-year shorten had a higher rate of the lelt ventricular （LV） reverse remodeling （65% vs. 44%, Z2 = 4.495, P - 0.038） and less VT/VF episodes （log-rank test, X2 - 10.207, P = 0.001 ） compared with TpTe I-year nonshortened group. TpTe immediately alter CRT-D independently predicted VT/VF episodes at l-year follow-up （hazard ratio [HR], 1.030; P = 0.001 ）. Conclusions： Patients with TpTe shortened at l -year after CRT had a higher rate of LV reverse remodeling and less VT/VF episodes. The acute changes of TpTe after CRT have minimal value on mechanical reverse remodeling and ventricular arrhythmia.
