Chronic pancreatitis is a long-standing inflammation of the pancreas,characterized by progressive inflammatory and fibrotic changes,resulting in permanent structural damage of pancreatic parenchyma[1].Pancreatitis(chronic or acute)is the primary risk factor for pseudo-splenic artery aneurysms,along with pancreatic pseudocysts and *** the disease progresses,patients with chronic pancreatitis may develop complications due to exocrine and endocrine pancreatic functional loss,such as fat malabsorption with steatorrhea,glucose intolerance,and ultimately diabetes mellitus[1,2].Furthermore,severe pancreatic inflammation can cause weakening of vessel walls,with subsequent formation of arterial *** artery is the most commonly affected visceral artery[2,3].Liver cirrhosis,portal hypertension,liver transplantation,atherosclerosis,hypertension,pregnancy and multiparity are main risk factors for true splenic artery aneurysms[2].Rupture and intraperitoneal bleeding is the cause of death in 30%−50%of ***,prompt diagnosis and appropriate treatment are of great clinical importance[4,5].Herein,we present a case of a giant splenic artery pseudoaneurysm within a walled of necrosis involving pancreatic parenchyma,as a complication of long standing chronic pancreatitis.

Responding to a need for experimental data on a standard wind tunnel model at high angles of attack in the supersonic speed range, and in the absence of suitable reference data, a series of tests of two HB-2 standard models of different sizes was performed in the T-38 trisonic wind tunnel of Vojnotehnickˇi Institut(VTI), in the Mach number range 1.5–4.0, at angles of attack up to+30°. Tests were performed at relatively high Reynolds numbers of 2.2 millions to 4.5 millions(based on model forebody diameter). Results were compared with available low angle of attack data from other facilities, and, as a good agreement was found, it was assumed that, by implication, the obtained high angle of attack results were valid as well. Therefore, the results can be used as a reference database for the HB-2 model at high angles of attack in the supersonic speed range, which was not available before. The results are presented in comparison with available reference data, but also contain data for some Mach numbers not given in other publications.

To determine the lateral and vertical variations in crustal structure and their influence on the seismicity of the Western North China Craton,the Trans-North China Orogen,and the surrounding regions,the wavelet multi-scale structures,Moho depth,crustal density structures,and isostatic state are modelled using Bouguer gravity anomaly data,topography,and earthquake focal *** obtained homogeneous crustal densities and deviations of<1 km between the crustal thicknesses estimated from the isostatic model and those inverted from the Bouguer gravity anomalies in the Ordos Block,the Inner Mongolia Suture Zone,the Sichuan Basin,and the Jizhong *** results provide new evidence for relatively simple and stable continental crustal structures,and indicate that these regions will remain stable in both the vertical and lateral *** Hetao Graben,Yinchuan Graben,Weihe Basin,and Shanxi graben system have heterogeneous crustal densities and are isostatically *** contrast,the crust beneath the Yinshan Uplift,Lvliang Uplift,and northern and central Taihang Uplift is thin and *** heterogeneous crustal densities and non-isostatic state beneath the Tibetan Plateau and Qinling Central China Orogen indicate that these two blocks are unstable in the vertical and lateral *** Cenozoic deformation of the North China Craton is thought to be driven by lithospheric stresses related to the India-Eurasia collision and Pacific slab retreat in South East Asia,we suggest that gravitational potential energy created by the heterogeneous crustal structure modulates these first-order *** results of this study could constrain the causes of seismicity in systems surrounding the Ordos Block.

The effect of austenitizing temperature and Cr, Mo and Mn addition on microstructure and mechanical properties of V microalloyed medium carbon steel has been studied by means of metallography and mechanical testing. The addition of Cr, Mn and Mo leads to a decrease in yield strength （YS） by approximate 100 MPa in comparison to the base steel. It is assumed that Mn and Mo increase hardenability by promoting the formation of bainitic sheaves （BS）, i.e. by suppressing the formation of ferrite-pearlite and acicular ferrite （FP-AF）. Cr at the level used in this work is not that effective. Presence and packet size of bainitic sheaves decrease the Charpy V-notch impact energy at 20 ℃ （CVN20） in comparison to ferrite-pearlite and acicular ferrite microstructures.

全球范围而言,水泵效率和性能的热力学测试方法大约于十多年前在工业领域开始得到大量应用,但目前在泵站测试中使用还不是很广泛。由于缺少直接的工业应用标准去保证热力学法测试结果的准确可靠,且多数泵站自身又缺乏足够经验来开展独立研究测试,所以迫切需要一些通用性的指导原则来推动相关领域的进展。通过对多城市多泵站的水泵效率测试和研究,本项目完成了41个泵站的152个城市供水水泵的性能测试。其中57个水泵同时使用了热力学法和传统方法。通过大量的现场测试,并与采用电磁流量计、超声波流量计等传统测试方法的对比,积累了许多关于热力学法和传统方法在水泵性能测试中的经验和技巧;测试研究成果进一步明确了热力学法的适用条件和范围,通过对实测中遇到的各种情况的处理和总结,提出了热力学方法的通用性指导应用原则。
