| 1 | 猪舍内气流变化的模拟研究显示文摘圈养动物舍内的气流变化对于室内的污染物扩散起到非常关键的作用,采用基于有限容积方法的计算流体动力学(CFD)软件对建于奥胡斯大学农业工程研究所空气物理实验室中的1:12.5猪舍模型内的气流进行了稳态和三维模拟。将模拟的气流速度与室内一个参考点的实际测试速度进行了对比,同时分析了气流入口不同紊流动能及扩散率取值对室内测试参考点气流速度模拟值的影响。结果表明,模拟值与测试值的相对误差在0.4%~11.4%之间。 | 佟国红 张国强 MORSING S STROM JS RAVN P | 2007 | 沈阳农业大学学报2007，38，3： | 25 |
| 2 | High-resolution multimodal flexible coherent Raman endoscope显示文摘Coherent Raman scattering microscopy is a fast,label-free,and chemically specific imaging technique that shows high potential for future in vivo optical histology.However,the imaging depth in tissues is limited to the sub-millimeter range because of absorption and scattering.Realization of coherent Raman imaging using a fiber endoscope system is a crucial step towards imaging deep inside living tissues and providing information that is inaccessible with current microscopy tools.Until now,the development of coherent Raman endoscopy has been hampered by several issues,mainly related to the fiber delivery of the excitation pulses and signal collection.Here,we present a flexible,compact,coherent Raman,and multimodal nonlinear endoscope(4.2mm outer diameter,71mm rigid length)based on a resonantly scanned hollow-core Kagomé-lattice double-clad fiber.The fiber design enables distortion-less,background-free delivery of femtosecond excitation pulses and back-collection of nonlinear signals through the same fiber.Sub-micrometer spatial resolution over a large field of view is obtained by combination of a miniature objective lens with a silica microsphere lens inserted into the fiber core.We demonstrate high-resolution,high-contrast coherent anti-Stokes Raman scattering,and second harmonic generation endoscopic imaging of biological tissues over a field of view of 320μm at a rate of 0.8 frames per second.These results pave the way for intraoperative label-free imaging applied to real-time histopathology diagnosis and surgery guidance. | Alberto Lombardini Vasyl Mytskaniuk Siddharth Sivankutty Esben Ravn Andresen Xueqin Chen Jérôme Wenger Marc Fabert Nicolas Joly Frédéric Louradour Alexandre Kudlinski Hervé Rigneault | 2018 | Light(Science & Applications)2018，7，1： | 6 |
