本文探究了水热处理对热浸镀铝/MAO陶瓷膜层表面形貌、物相组成、耐蚀性能等方面的影响,并通过高温铝液腐蚀实验分析了热浸镀铝/MAO/水热处理试样的耐铝液腐蚀能力。结果表明:热浸镀铝/MAO/水热处理试样的陶瓷膜层主要由Al相、Al2O3相和ZrO2相组成,适宜的水热处理时间能够使得陶瓷膜层表面更加平整光滑,微孔数量减少,耐蚀性能更好。通过高温铝液腐蚀实验发现,经热浸镀铝/MAO/水热处理工艺改性后的316 L不锈钢试样表面更加平整,腐蚀失重和腐蚀速率仅为未镀膜的316 L不锈钢试样的一半。

Many weather radar networks in the world have now provided polarimetric radar data(PRD)that have the potential to improve our understanding of cloud and precipitation microphysics,and numerical weather prediction(NWP).To realize this potential,an accurate and efficient set of polarimetric observation operators are needed to simulate and assimilate the PRD with an NWP model for an accurate analysis of the model state *** this purpose,a set of parameterized observation operators are developed to simulate and assimilate polarimetric radar data from NWP model-predicted hydrometeor mixing ratios and number concentrations of rain,snow,hail,and *** polarimetric radar variables are calculated based on the T-matrix calculation of wave scattering and integrations of the scattering weighted by the particle size *** calculated polarimetric variables are then fitted to simple functions of water content and volumeweighted mean diameter of the hydrometeor particle size *** parameterized PRD operators are applied to an ideal case and a real case predicted by the Weather Research and Forecasting(WRF)model to have simulated PRD,which are compared with existing operators and real observations to show their validity and *** new PRD operators use less than one percent of the computing time of the old operators to complete the same simulations,making it efficient in PRD simulation and assimilation usage.

经皮肾镜取石术(percutaneous nephrolithotripsy,PCNL)是治疗肾结石的常用方法,术中出血是其最常见的并发症之一。本文报道了1例PCNL中发生下腔静脉损伤导致术中大出血的患者,患者出现血流动力学不稳定,因此立即进行剖腹探查手术。在探查过程中发现下腔静脉和肾血管受损,尝试修补下腔静脉,但仍有大量出血。考虑到肾血管损伤无法修复,最终决定行肾切除术。通过对相关文献的综述,发现误入下腔静脉是PCNL术中的罕见并发症。术中的穿刺点选择、导丝操作和扩张深度等因素可能增加了发生下腔静脉损伤的风险。通过总结这一病例和相关文献,可以提高医生对该并发症的认识和警惕性,从而减少类似并发症的发生。

Seasonal variations of rainfall microphysics in East China are investigated using data from the observations of a twodimensional video disdrometer and a vertically pointing micro rain radar. The precipitation and rain drop size distribution(DSD) characteristics are revealed for different rain types and seasons. Summer rainfall is dominated by convective rain,while during the other seasons the contribution of stratiform rain to rainfall amount is equal to or even larger than that of convective rain. The mean mass-weighted diameter versus the generalized intercept parameter pairs of convective rain are plotted roughly around the "maritime" cluster, indicating a maritime nature of convective precipitation throughout the year in East China. The localized rainfall estimators, i.e., rainfall kinetic energy–rain rate, shape–slope, and radar reflectivity–rain rate relations are further derived. DSD variability is believed to be a major source of diversity of the aforementioned derived estimators. These newly derived relations would certainly improve the accuracy of rainfall kinetic energy estimation, DSD retrieval, and quantitative precipitation estimation in this specific region.

二氢嘧啶酶样蛋白3 (dihydropyrimidinase-like 3,DPYSL3)又称塌陷反应调节蛋白4 (collapse response mediator protein 4,CRMP4),是一种在神经系统中高表达的胞质磷蛋白。其不仅参与细胞伪足中肌动蛋白的组成,也用于组装细胞骨架,还与细胞上皮-间质转化(epithelial-mesenchymal transition,EMT)过程有关,这些特性可能与肿瘤增殖与转移功能有关。近年来有研究表明,DPYSL3参与多种癌细胞的增殖与侵袭过程,例如前列腺癌、膀胱癌、胃癌与肝癌等。然而,DPYSL3在不同肿瘤中的表达与预后存在明显的异质性。因此,进行DPYSL3在肿瘤表达水平的研究有望成为在不同肿瘤恶性程度与诊断过程中的生物标志物,从而提高肿瘤诊断率与患者预后水平。本文对DPYSL3在不同肿瘤中的表达、生物学功能及其对肿瘤的诊断、治疗及预后价值进行总结与探索,为肿瘤研究提供新思路。

Six-year Statuma mandarin (Citrus unshiu Marc. Cv. Miyagawa Wase) trees were used as materials to investigate the effects of plastic film mulching on quality and appearance of Statuma mandarin fruit during three periods of cell division, cell enlargement and mature stages. The results showed that mulching during the cell division and early-mature stages increased total sugar and reduced sugar content of fruit as well as the Vc content, compared to the control. However, the titratable acid content, fruit size, peel weight and single fruit weight were all lower than the control. Film mulching during the cell division phage resulted in higher edible fruit rate, while the fruit shape index was similar to the control. Mulching during the early-mature stage didn’t affect the edible rate of fruit, but caused lower fruit shape index. Compared to the control, film mulching during the cell enlargement period caused lower total and reducing sugar content, titratable acid content and edible rate, while the Vc content was a little bit higher than the control. In addition, the fruit size, peel weight, single fruit weight and fruit shape index were all lower than the control. Mulching during the early-mature period effectively enhanced the content of total and reduced sugar and Vc and decreased the titratable acid content. Hence, it increased fruit quality but had negative effect on fruit appearance.
