Flooding Efficiency of Flooding systems and Wettability Study on the Simulaitn Rock Surface [PDF]

open access: yes, 2004
为了研究驱油体系在模拟岩芯表面的润湿性,为微重力应用研究提供依据,选择胜利纯梁采油厂c6—41井原油,应用正交实验设计,通过最低瞬时界面张力测定,筛选出阴离子表面活性剂sDc—V、非离子表面活性剂FBB、HPAM和复碱的驱油体系配方.开展室内模拟驱油实验,同时测定驱油体系溶液对模拟岩芯的接触角,并且关联驱油效率和接触角之间的关系,发现驱油效率越高 ...

Sol-Gel Preparation of Modified TiO2 Films and Its Superhydrophilicity Performance in Absence of UV Irradiation Investigation [PDF]

open access: yes, 2015
具有自清洁特性的超亲水薄膜,以其优异的超亲水性能,在环境净化、生物医学和建筑材料等众多领域有着广泛的实用潜力。然而,TiO2超亲水薄膜的实际应用却一直被限制。一方面,TiO2作为一种宽禁带半导体,只有在紫外光辐照条件下才具有优异的超亲水性,维持其超亲水性能强烈依赖于紫外光诱导,无法实现可见光响应或暗态下的超亲水性;另一方面TiO2超亲水薄膜受限于制备工艺的复杂和生产成本的高昂。因此,本文以钛酸正丁酯(Ti(OBu)4)为钛源,采用工艺操作简单、适合工业生产等优点的溶胶-凝胶法(Sol-Gel ...

DLC film prepared with multiple gas sources and its applications [PDF]

open access: yes, 2016
类金刚石膜(Diamond-LikeCarbon,DLC)是一种介于金刚石和石墨之间的非晶结构材料。类金刚石膜具有和金刚石类似的许多独特的优良性能,因此被广泛应用在机械、光学、电学以及生物等领域。 等离子体化学气相沉积(PECVD)法是生长含氢DLC膜的常见方法,通常把衬底放在PECVD腔体中的源电极上生长DLC薄膜,这样生长的DLC膜具有更高的硬度。本文采用浸入式PECVD方法生长DLC薄膜,把衬底浸入到等离子体中,使其面临的电场强度和离子团密度等生长参数有别于源电极式PECVD法 ...

固体潤滑剤による高温度玉軸受の混合気潤滑 [PDF]

open access: yes
The need is beboming more and more urgent for bearings operating at very high temperatures. But present-day liquid lubricants are temperature-limited owing to their characteristics,but solid lubricants are chemically more stable.
