This paper has analyzed the influences of the heat input of welding arc, the latent heat of solidifica- tion,fluid flow of liquid metal on the heat conductivity pertaining to welding solidification crack of stainless steels. As a result,two - dimensional heat conduction models with prescribed heat flux mov- ing along the the have been developed that can simulate welding arc, convection and radiation heat loss from top and bottom surfaces of the workpiece. Finally, the finite element model was used to ana- lyze and calculate the temperature field.

During the late expansion and recovery phases of a substorm from 07:35UT to 08:00UT on 24August 2005,Cluster satellites(C1 and C3)observed a series of earthward/dawnward bursty bulk flows(BBFs)and the repeated drops of energetic(-128keV)electron fluxes in the midtail plasma sheet(-18.1≤XGSM≤-16.9RE).By analyzing the BBF-associated changes in the charged particle’s loss cone,waves and energetic particles,we found that the loss of energetic electrons is mainly due to the pitch angle scatterings driven by the lower-band whistler waves in the BBF-impacted regions,whereas the influence of particle’s azimuth drifts(e.g.,the Ex×Bz drifts independent of charges)are quite weak *** the loss cone of the charged particles is narrow(half loss cone angleαc.15o)in the midtail plasma sheet,the BBFs can enlarge the particle’s loss cone through the compression of local magnetic *** isotropic electron pitch angle evolutions and concurrent flux drops certify that the plasma sheet energetic electrons can be rapidly scattered into the loss cone(2αc)in the process of whistler wave *** the energetic electrons can experience the northern and southern conjugated losses during the wave-particle resonant interactions,their flux drops are also considerable when the plasma sheet was swept by the BBFs with the whistler waves many *** observations indicate that the BBFs with intense whistler waves mainly lead to the loss of the plasma sheet energetic electrons through the wave-driven pitch angle scatterings.

一、前言正反反复选择(RRS)程序首先由Comstock等(1949)为植物特殊配合力育种而提出。后由Bell等(1950)伸展到动物育种中。此后试验的主要目的是确定RRS对杂种性能和纯系选择(PLS)及对纯种性能选择的有效性。在当前,几乎所有商品育种畜都经受了PLS的高度选择,表明杂交育种对开发非加性变异是重要的。Legetes(1988)指出,杂种优势的利用已成为应用育种纲要的一个主要部分。在现代育种体系中,为了提高杂交性能,多采用RRS及其改进的RRS方法。本综述将从理论和实践上集中于RRS和PLS两体系的比较,并讨论各自的长处和改进的可能性。

Methane, an abundant one-carbon（C1） resource, is extensively used in the industrial production of vital fuels and value-added chemicals. however, current industrial methane conversion technologies are energy-and carbon-intensive, mainly due to the high activation energy required to break the inert C–h bond, low selectivity, and problematic side reactions, including CO2emissions and coke deposition. Electrochemical conversion of methane（ECM） using intermittent renewable energy offers an attractive solution, due to its modular reactor design and operational flexibility across a broad spectrum of temperatures and pressures. This review emphasizes conversion pathways of methane in various reaction systems, highlighting the significance and advantages of ECM in facilitating a sustainable artificial carbon cycle. This work provides a comprehensive overview of conventional methane activation mechanisms and delineates the complete pathways of methane conversion in electrolysis contexts. Based on surface/interface chemistry, this work systematically analyzes proposed reaction pathways and corresponding strategies to enhance ECM efficiency towards various target products, including syngas, hydrocarbons, oxygenates, and advanced carbon materials. The discussion also encompasses opportunities and challenges for the ECM process, including insights into ECM pathways, rational electrocatalyst design, establishment of benchmarking protocols, electrolyte engineering, enhancement of Ch4conversion rates, and minimization of CO2emission.

五、讨论 1.理论关于以位点模式为基础的研究范围问题,Bowman(1959)等指出,位点水平上的统计一般建立在4种假设上:①没有上位;②每位点不超过两个等位基因;③连锁平衡;④一个无限大的群体。毫无疑问,这些假设降低了理论的实用价值。在以动物数量遗传为基础的分析中(公式9、10和11),RRS对PLS的效应在很大程度上取决于加性、非加性方差和r_(pc)。一般来说RRS与PLS相比较的论证结果与试验是一致的。McNew等(1976)报道,RRS(和PLS)的有效反应率与理论值相似。在Brown(1980)的试验中。
