1乳腺肿块的超声弹性成像表现并特别关注乳腺纤维腺瘤的诊断显示文摘本研究的目的是应用超声弹性成像显示乳腺肿块并分析其表现,尤其是乳腺纤维腺瘤。本研究最初包括235例病人共计302个乳腺病变,均经针吸活检取得病理证实。其中270个病变在常规超声检查中呈实质性肿块,作为本研究资料。其中115个(42.6%)组织学证实为纤维腺瘤,155个(57.4%)为非纤维腺瘤。这些肿块又被进一步分为纤维囊性病变、潜在低度恶性病变和恶性病变。纤维腺瘤也根据组织学表现分为3个亚型,以便根据弹性成像评分进行对照分析。E.F.C.

23D Flow Past Transonic Turbine Cascade SE 1050-Experiment and Numerical Simulations显示文摘This paper is concerned with experimental and numerical research on 3D flow past prismatic turbine cascade SE1050 (known in QNET network as open test case SE1050). The primary goal was to assess the influence of the inlet velocity profile on the flow structures in the interblade channel and on the flow field parameters at the cascade exit and to compare these findings to results of numerical simulations. Investigations of 3D flow past the cascade with non-uniform inlet velocity profile were carried out both experimentally and numerically at subsonic (M 2is = 0.8) and at transonic (M 2is = 1.2) regime at design angle of incidence. Experimental data was obtained using a traversing device with a five-hole conical probe. Numerically, the 3D flow was simulated by open source code OpenFOAM and in-house code. Analyses of experimental data and CFD simulations have revealed the development of distinctive vortex structures resulting from non-uniform inlet velocity profile. Origin of these structures results in increased loss of kinetic energy and spanwise shift of kinetic energy loss coefficient distribution. Differences found between the subsonic and the transonic case confirm earlier findings available in the literature. Results of CFD and experiments agree reasonably well.D.imurda J.Fürst M.Luxa 2013Journal of Thermal Science2013,22,4:3

5镀银层的防变色保护显示文摘镀银层被广泛应用于电子和通信工业。然而,在存放或使用二、三个月后,镀银层就会发生变色,从而降低了可焊性,并增加了接触电阻。到现在仍没有一种真正有效的抗变色方法。因此,研究银层变色机理和防止变色的方法,依然是很重要的。变色的原因曝露在光下和硫化钠溶液中,对银层的影响在以前我们已经讨论过了。表1概括了光波波长和曝露时间对银层变色的影响。表1的数据表明,波长相对短的2537A的紫外光比波长较长的光对银层有更大的光变色作用。J.F Fang Zi Cai 李瑞敏 1990材料保护1990,23,1:2
