The hydrogen evolution reaction(HER) – as an essential half reaction in water electrolysis and chlor-alkali process has been well studied in acidic electrolyte, but much less has been known in basic medium. In this study, by combining kinetic modeling and electrochemical measurements, we show that hydrated alkali cation clusters can adsorb on the surface of HER catalyst in basic electrolyte. The bound H2 O molecules in the "clusters" can thus be in-situ activated through the hydration effect, which dissociate on the catalyst surface as the reactant of HER. The effective concentration and hydration energy of alkali cation can influence the H2 O dissociation rate, and hence the kinetics of HER. Our work demonstrates a new understanding of the HER mechanism in basic reaction electrolyte.

目的研究胫骨干骨折交锁髓内钉内固定失败的原因以及相应处理策略。方法选择2010年5月~2015年12月本院收治的胫骨干骨折交锁髓内钉内固定失败患者11例,回顾剖析导致髓内钉内固定失败原因,探寻改进方法,制定处理方法。结果胫骨髓内钉内固定失败的主要原因有:术中大范围剥离胫骨骨折端周围软组织、胫骨平台进钉点选择错误、成角移位未纠正、髓内钉型号选择错误、螺钉固定不稳妥、远端锁钉置入位置错误、术后切口感染、骨质缺损过多、术后不正确的功能锻炼、内固定材料选择错误、内固定材料材质不合格等,经过5~13个月相应处理后,11例胫骨干骨折髓内钉内固定失败患者得到有效治疗,骨折顺利愈合,小腿功能恢复正常。结论胫骨干骨折行髓内钉内固定术治疗时一定要综合考虑患者是否出现严重软组织损伤、骨折类型与特点等因素,合理选用髓内钉固定与手术技巧,注意术后护理与康复指导锻炼,可以提高胫骨髓内钉内固定治疗成功率。

The genetic linkage map has been constructed with 125 SSR markers based on BC1:2 population consisting of 322 lines derived from the combination of (CML270×478) ×CML270 in maize (Zea mays L.), covering 1939.0 cM of maize genome. The average mapping distance was about 15.5 cM. Three major QTLs of the relative resistant index of re- sistance to maize sheath blight (Rhizoctonia solani) had been located on chromosomes 1, 7 by composite interval mapping (CIM). 7 QTLs of the plant height have been located on chromosomes 3, 4, 5, 6. Five QTLs of ear height have been located on chromosomes 3, 4, 6. The resistance to the sheath blight is shown to be not relative to plant height and ear height genetically. Inbred line CML270 was used for mo- lecular assisted selection and cloning the genes.

Based on Simultancous Multithrtading (SMT), we propose a fault-tola antscheme called Tri-modular Redun-danlly and Simultaneously threaded processor with Recovery (TRSTR),TRSTR features as following: First, we introduce an arbitrator context into thtconventional SRT(Simultaneous and Redundantly Threaded), which acts as an arbitrator when results from the other twocontexts disagree, or acts as an ordinary thread generally, thus making full use of SMT'sparallelism. Second, we append reconfigurablefeature to sphere of replication in SRT, making it moreflexible for changing demands and situations Third, TRSFR has two working modes: Tri-Simultancouswith Voling (TSV) and Dual-Simultaneous with Arbitrator CDSA), which can switch at will. Finally, inaddition to transient-fault coverage, TRSTR has on-line self-checking and self-recover ingabilities, so as to shield off some permanent faults and reconfigure itself without stopping thecrucial job. improving its reliability and availability.
