BACKGROUND Extragastric lesions are typically not misdiagnosed as gastric submucosal tumor(SMT).However,we encountered two rare cases where extrinsic lesions were misdiagnosed as gastric *** SUMMARY We describe two cases of gastric SMT-like protrusions initially misdiagnosed as gastric SMTs by the abdominal contrast-enhanced computed tomography(CT)and endoscopic ultrasound(EUS).Based on the CT and EUS findings,the patients underwent gastroscopy;however,no tumor was identified after incising the gastric *** surgical exploration revealed no gastric lesions in both patients,but a mass was found in the left triangular ligament of the *** patients underwent laparoscopic tumor resection,and the postoperative diagnosis was hepatic *** During EUS procedures,scanning across different layers and at varying degrees of gastric cavity distension,coupled with meticulous image analysis,has the potential to mitigate the likelihood of such misdiagnoses.

乙二醇和丙三醇的吸收光谱和荧光光谱研究

光谱学与光谱分析 2007年第7期27卷 1381-1384页

作者：徐辉朱拓虞锐鹏江南大学信控学院江苏无锡214122 江南大学理学院江苏无锡214122 江南大学检测中心江苏无锡214122

对乙二醇和丙三醇的紫外吸收光谱和荧光光谱进行了实验研究和理论分析,发现两者的最大吸收波长均位于198 nm,且在适当的紫外波长激励下均能发射出荧光,文章中给出了相应的荧光光谱图,但荧光相对强度和激发波长间似乎没有明显变化规律,... 详细信息

对乙二醇和丙三醇的紫外吸收光谱和荧光光谱进行了实验研究和理论分析,发现两者的最大吸收波长均位于198 nm,且在适当的紫外波长激励下均能发射出荧光,文章中给出了相应的荧光光谱图,但荧光相对强度和激发波长间似乎没有明显变化规律,其原因有待进一步探索。从乙二醇的一阶导数荧光光谱,得知在210 nm激发下荧光相对强度随时间变化最快,在225 nm激发下的绝大多数时间内变化速率最慢。另外,文章还从量子计算出发,采用一维势阱模型,根据电子从HOMO到LUMO的跃迁,计算出了两者的吸收波长值。比较分析了计算值与实验值之间的误差,考虑到将分子直链化后其键长与实际情况有所差别,结果认为理论计算有一定的参考价值。

Radiation flow through gold-doped hydrocarbon foam is investigated and a model is presented to calculate effective opacity for an inhomogeneous,pressure-equilibrated gold/foam mixture based on the Levermore–Pomraning method for binary stochastic *** effective opacity dependance on the size of the gold particles and the foam temperature are *** results suggest that when the mixture temperature is lower than 250 eV,the opacity difference between the 5μm particle mix case and the atomic mix case is large enough to induce a significant discrepancy in radiation transport,which is confirmed by the hydrodynamic simulation.

调查2003年和2004年在上海证券交易所上市的A股上市公司的企业价值及其产业特征,观察到了分散化的溢价效应。研究发现,分散化公司较之非分散化公司具有更高的企业价值;而且,分散化战略对企业价值存在显著的正向解释力。文章进一步验证了分散化的价值创造功能。本文推测分散化的组织优势源于债务融资的税盾收益以及有效的内部资本市场所产生的财务协同效应,并取决于外部资本市场的发达程度和金融体系的完善程度,以及经济制度的市场化程度和开放程度。

一国所选择的汇率制度,应是既能适应经济发展的要求,又能促进经济的协调运行。印度与中国具有大致相同的有关汇率制度变革需求的现实背景,但是印度货币当局在实施有管理的浮动汇率制度中,保持了卢比汇率的基本稳定,值得我们借鉴。目前,中国具有支撑人民币强势的坚实基础。人民币汇率制度变迁应该根据中国在全球金融经济链条中的民族利益而不是屈从于某些大国政治利益而确定。
