| 1 | EFFECT OF STRAIN RATE(?) ON STRAIN HARDENING EXPONENT n OF SOME METALLIC MATERIALS显示文摘Fariabh strain rate tension tests for 4 metallic materials show that as the strain rate in creases the strain hardening exponent n decreases.The trend follows a two stage linear relation between n and lg(?).When (?)<(?)ep’i.e.under quasi-statie loading,n can be consideredas a constant,but when(?)>(?)ep’,n decreases rapidlv till an ideal plastic state,n=0.Thecharacteri=ations and mechanisms of so fiening induced by high (?)are discussed. | TANG Changguo, ZHU Jinhua, ZHANG Yuhua, ZHOU HuijiuResearch Institute for Strength of Metals.

| 5 | Studies on Material Cycling in Evergreen Broad-Leaved Forest Ecosystem in Hangzhou: Ⅰ. Precipitation Distribution显示文摘Through the long-term plot studies plot studies on the precipitation distribution in the evergreen broad-leaved forest ecosystem in Hangzhou for two years,it was indicated that the pattern of precipitation distribution included larger amounts of penetration water and stemflow and a lower amount of interception water.The results revealed that the main factors to infulence the percentages of penetration and stemflow were the air temperature and the leaf area of the forest.The quantity of seepage through the litter layer was much larger than that through the soil layers which decreased sharply with soil depth.The output of water from the ecosystem by surface runoff and deep infiltration through the soil was much lower,only being 5.20 percent of the rainfall,while the water evapotranspiration loss was as large as more than 90 percent of it.The losses by the soil evaporation and plant evapotranspiration were the largest part of output in this forest ecosystem. | JIANG QIU-YI, HE LI-MING, YU YI-WU, CHEN GUO-RUI and SHI DE-FAZhejiang Forestry College, Lin’an.

| 6 | 固体聚合物电极反应器中大豆油氢化作用的电流效率显示文摘与H2O2燃料电池类似,以水为阳极进料和氢源,在固体聚合物电极(SPE)反应器内进行了大豆油的电化学催化氢化。反应器的关键部件是膜电极组件(MEA),其由稀有金属黑阴极、RuO2粉末阳极、Nafion 117阳离子交换膜构成。SPE反应器在温度60℃、压力0.1MPa、阴极进料为工业用大豆油下进行分批循环操作。研究了可能影响油氢化电流效率的 各种因素,如阴极催化剂的类型、催化剂载量、阴极催化剂粘合剂用量、电流密度、反应物进料速率。发现用不同阴极催化剂时的电流效率顺序为:Pd>Pt>Rh>Ru>1r。用Pd黑阴极时,油氢化电流效率随电流密度的升高而降低,0.50A/cm^2时为70%,0.490A/cm^2时为25%。电流脉冲频率在0.25-60Hz时对电流效率没有影响。Pd和Pt阴极催化剂的最佳载量均为2.0mg/cm^2。只要粘合剂的总量不大于30%(质量分数,以干基催化剂为基准),大豆油氢化作用的电流效率就不会受到Nafion和PTFE阴极催化剂粘合剂的影响。当电流密度为0.100A/cm^2时,大豆油的进料速率由80mL/min升至300mL/min时,电流效率由60%升至70%。在进料管线上加镍丝网湍流促进器,进由速度为80mL/min时电流效率可高达70%。 | An.,W 高旭东 等 | 2000 | 绿箭信息2000，1，8： | 0 |
| 7 | 食用油在固体聚合物电解反应器中的电化学氢化之二—氢化选择性研究显示文摘60℃和0.1MPa下,在固体聚合物电解反应器(SPE)中电化学氢化豆油。实验目的主要是确定可提高脂肪酸氢化选择性的阴极设计和反应器操作条件。增大豆油在Pd黑阴极催化层的流量(通过增加阴极碳纸/布衬层材料的多孔性,增大油料流通的速率,并在油料管道中插入一个湍流增进器)降低硬脂酸和亚油酸在油品中的浓度[例如:碘值(IV)98的油含有质量分数为12.2%的C18:0和2.3%的C18:3]。在Pd黑粉末阴极上电镀另外一种金属(Ni、Cd、Zn、Pb、Cr、Fe、Ag、Cu或Co)时,可显著增加亚麻酸脂、亚油酸酯和亚油酸的选择性。例如:可应用钯/钴阴极来合成含质量分数5.3%硬脂酸和质量分数2.3%亚油酸的IV值为113的豆油。豆油产品中反式异构体的质量分数为6%-9.5%(取决于产品的IV值,与特定的异构化指数0.15-0.40相对应)且获得高脂肪酸氢化选择性时操作条件下也不必显著地提高。 | An.,Weidong Warne | 2000 | 绿箭信息2000，1，8： | 0 |
