Preparation of the cathode includes:shaping under the press of 40Mpa, sintering at 550℃for 1 hour and at 900℃for 8 hours and threading with molybdenum bar; Considering the literatures we choose CaCl2 as salt for preparation titanium. Pretreatment of salt is for 1 hour at 100℃and for 2 hours at 300℃. Partial pressure of oxygen which need lower than 5.11×10-7Pa to reduct titanium oxides and hygroscopic property of salt need a sealed equipment to electrolyse. And finally successfully designed a satisfied one and the results show that the equipment can be satisfied the requirment of the experiment. Flow of the inert gas is 1.5L/min, the voltage is 2.8 V, temperature is 850℃and time is 2 hours during pre-electrolysis. Flow of the inert gas is 0.2L/min, the voltage is 3.1 V, temperature is 900℃and time changes with the mass of TiO2 during electrolysis, namely the greater need the longer time; To eliminate influence of salt and other impurities, the products need to wash with distilled water and dilute chlorhydric acid , then wash with dilute hydrochloric acid under supersonic wave assistant. Finally, electrometical properties of the electrolysis of TiO2 is researched by cyclic voltammetry and chronoamperometry, and results show that there are two main reodox steps, namely from TiO2 to TiO and from TiO to Ti.

阴极制备主要包括40MPa压力下模压成型、两段式烧结(1小时内升至550℃保温1小时,再1小时升温至900℃保温8小时)及烧结后TiO2块打孔用钼棒串接三个主要环节;实验中选用CaCl2作为电解熔盐,并对其进行预处理(100℃,保温1小时; 300℃,保温2小时);经热力学计算,还原钛氧化物的氧分压至少要低于5.11×10-7Pa,结合电解过程中所用熔盐CaCl2有极强的吸水性的特点,电解装置应有较高的密封性,自行设计了一套密封性可靠的电解装置,便于实验过程中熔盐预处理和氧分压的控制;通过干燥处理预电解过程中Ar流量大约为1.5L/min、电压为2.8 V、温度为850℃、时间为2小时,电解过程中Ar流量大约为0.2L/min、电压为3.1V、温度为900℃,实验结果表明电解时间与TiO2质量密切相关,质量越大需要电解的时间越长;通过自来水冲洗—稀盐酸浸泡、洗涤—在超声波辅助作用下稀盐酸洗涤,可减少熔盐及其它杂质对电解产物检测结果的影响;最后,通过循环伏安法、计时电流法对电解机理的研究,确定电解还原TiO2制备金属钛主要经历了TiO2-TiO-Ti的过程。

The reliability of analysis result depends largely on the in-house experimental conditions. Unlike the previous analysis that only concerns the sole effect of permeable pressure, this article considers both permeable and confining pressure and deformation characteristics of concrete material under the interaction of them according to the real work state of construction, which may leads to the changing pattern of permeable rate as listed below: permeable rate always reaches its peak with the time process going on, than goes down and remains straight on some certain value; The PR will tend to decline while the confining pressure is increased, and the time taken before the peak will be extended as well; Under the constant permeable pressure and circularly changing confining pressure, the minus-exponential ascend and descend relationship could be applied between the PR and Time axes respectively with crannied and intact concrete samples, and the PR of crannied concrete is far more larger than that of intact concrete. The change pattern of concrete could also be mathematically analogized using the least square method.

室内的实验条件是研究成果可靠性的重要因素,而以往的研究都只考虑了渗透压单一作用,本文根据混凝土结构的实际工作状态,同时考虑了围压与渗透压共同作用下的混凝土材料的渗透性变化特征,得出了混凝土材料在围压作用与渗透压共同作用下的渗透率的变化规律:渗透率都是随时间推移先达到一个峰值,再降低并趋于平稳;渗透率会随围压的增大而减小,并且峰值的到达时间也会随之延长;在渗透压不变,围压升降循环的情况下,有裂缝、无裂缝混凝土的渗透率变化规律是随时间成负指数关系上升、下降,且有裂缝混凝土试件的渗透率远远高于无裂缝混凝土的渗透率,并对混凝土的变化规律运用最小二乘法进行数学拟合。

论文以解决陕北地区的收入问题,植被问题以及粮食产量问题为出发点,首先从理论上分析了包络分析方法在陕北地区退耕还林中运用的可行性,然后结合陕北地区目前的实际情况,综合分析出影响陕北地区退耕还林的关键的七个因素作为输入指标:水利水保设施投入,农作物投入,经济林种支出,防护林支出,其它经济作物,草类支出,畜牧业投入;以退耕还林所要解决的最终问题作为输出指标:GDP收入、农民人均纯收入、水土流失减少量、牧业总产值、粮食产量、林业总产值、其他经济作物总产值。将各指标所对应的数据代入模型后,通过分析求解得出非有效的决策单元,再运用包络分析方法的一些基本原理对非有效的决策单元进行调整,由此所得的数据对陕北地区的实际投入具有很好的指导意义。同时,又针对陕北地区在退耕还林过程中以及之后可能面临的困境,提出了一些建议和对策。最终使得陕北地区的投资环境尽快得以改善,使农民尽快脱贫致富,使人口、资源、环境的关系尽快纳入良性循环的轨道上。
