6Preliminary studies on the ionic pulse of snowmelt runoff in the Urumqi River, Xinjiang, Northwest China显示文摘IONIC pulse of snowmelt and its runoff in seasonally snow-covered alpine catchments was de-fined by Johannessen et al. When a snowpack begins melting, the first meltwater drainingthrough the pack carries a large fraction of the soluble ions with it, an ionic pulse. 10% of thefirst meltwater may drain 80% of the soluble contents out of the snowpack within severalhours or days. In other words, an ionic pulse designates a peak in ionic concentration duringthe initial melting process of a snowpack. The peak has been proved by a plot test 10 timesLiu, FJ Williams, M Cheng, GD Yang, DQ 1997Chinese Science Bulletin1997,42,19:2
7Effect of Si, Al and Bi on Structure and Properties of As-welded and Austempered Ductile Iron Weld Metals during Gas Welding显示文摘Effect of Si, Al and Bi on the microstructure and mechanical properties of as-welded and austempered ductile iron weld metals has been studied with SEM, TEM, X-ray diffraction, image analysing system, tension and other test methods. Results show that increasing weld Si, Al and Bi content favours improving the chilling tendency of as-welded ductile iron weld and mechanical properties of austempered ductile iron weld and the mechanism is also discussed. On this basis the optimum chemical composition of weld is determined. The mechanical properties of weld and welded joint after austempering can match those of austempered ductileSun, DQ Zhou, ZF Cao, HC 1996Journal of Materials Science & Technology1996,12,5:2
8Relationship between state transition and photoinhibition of photosynthesis in wheat leaves显示文摘IT is well known that state transitions can keep even distribution of excitation energy betweenthe two photosystems (PS Ⅱ and PS Ⅰ), favoring efficient operation of the photosyntheticapparatus. However, state transitions are usually thought to be associated with low light con-ditions. Its physiological significance under high light conditions is still a controversial is-suc. Many people think that state transitions occur and take significant effect only underTan, XX Xu, DQ Shen, YG 1997Chinese Science Bulletin1997,42,21:2
9生理性线粒体破碎是心脏适应能量需求增加的正常现象显示文摘线粒体在心脏中起着双重作用:负责满足能量需求和调节细胞凋亡。通常认为,线粒体的分裂和碎裂是病理性应激(如缺血)的结果,是线粒体质量差的指标,并导致线粒体自噬和细胞死亡。然而,最近的研究表明,抑制裂变也导致线粒体功能减弱和心脏损害,说明裂变对维持心脏和线粒体生物能量平衡十分重要。刘莉 叶鹏 Coronado M Fajardo G Nguyen K Zhao M Kooiker KB Jung G Hu DQ Reddy S Sandoval E Stotland A Gottlieb RA Bernstein D 2018中华高血压杂志2018,26,1:2

11Grain Boundary-induced Shielding of Ni-base Single Crystals: Experimental and Analytical Study显示文摘Fracture behavior was studied for Ni-base single crystals and Ni-base bicrystals. The single crystals were machined from the bicrystal specimens to ensure that the single crystal samples had the same properties as those of the grains in the bicrystals. Using the three-point bend specimens, the fracture toughness Kc of single crystals and grain boundaries was measured,respectively. The two toughness values were little dependent on the ratio of the crack length to the height of the specimens. The grain boundary-induced shielding effect of fracture toughness was found in the grain-cracked bicrystals with normal front grain boundaries, The toughness varied with the distance between the crack tip and grain boundary. With the help of SEM analyses and numerical calculations, the mechanisms for the grain boundary-induced shielding are revealed. It is the grain boundary-induced redistribution of stresses and strains near the crack tip that induces the grain boundary-induced shielding. And the strain energy density criterion can be applied to the fracture of bicrystals. Agreement with experiments isYue, ZF Lu, ZZ Wu, DQ 1999Journal of Materials Science & Technology1999,15,5:2
