大豆蛋白纤维结构与染整性能的分析

分析了大豆蛋白纤维结构与漂白、染色等染整性能的关系,以及活性染料对大豆蛋白纤维染色的机理。结果表明:活性基反应性强(如乙烯砜、一氟均三嗪)的活性染料更适合大豆蛋白纤维染色,其不仅可与大豆蛋白组分反应,也可与聚乙烯醇组分反应。大豆蛋白和聚乙烯醇组分同时染色对纤维表面的颜色均一性是十分重要的。     

Closing information asymmetries: A scale agnostic approach for exploring equity implications of broadband provision

A persistent challenge for telecommunications policy is the determination of broadband provision footprints in both space and time. In the United States, Form 477 data from the Federal Communications Commission (FCC) provide a valuable snapshot of broadband provision at the block level, but there are often inconsistencies with the underlying data. These inconsistencies include overly-optimistic self-reports from providers, requirements to report broadband provision within inflexible census administrative units, and a modest temporal reporting schedule (biannual) with a significant, one year temporal lag. These uncertainties are often compounded by telecommunications providers refusing to disclose any information on service footprints, geographic expansion plans or the characteristics of populations served by broadband. This type of obfuscation drastically limits the ability of policy analysts to evaluate outcomes (both positive and negative) associated with service provision and the digital divide, more generally. With the recent entry of Google Fiber to several metropolitan markets in the United States, many of the broadband reporting and evaluation challenges have re-emerged. The purpose of this paper is to leverage basic data mining techniques, a scale agnostic geographic framework and exploratory spatial data analysis (ESDA), to uncover the geographic intricacies of Google Fiber (Fiber) service for both Provo, Utah and Austin, Texas and compare them to Form 477 reports. In addition, we use basic statistical approaches to explore issues of broadband access and equity, accounting for the differences in socio-economic and demographic status of the populace served/not served for both cities, as well as basic pricing within and between communities.

车用高分子材料耐刮擦性能研究与改善

对材料耐刮擦性的增容剂、PP结晶度、矿物填料、不同耐刮擦滑爽剂等的影响性能进行分析,耐刮擦改性聚丙烯(PP)是为汽车所制备的。通过实验结果表明了改性之后的PP的耐刮擦性能很强,它的改变与反应型高聚硅氧、矿物填料的粒径较小、高结晶PP有很大的关系,所以就形成了汽车的零部件,完全可以应用到汽车中。     

高性能钢纤维混凝土在超低梁的应用

32m超低高度梁是我国铁路梁施工常用梁体结构。采用后张法预应力施工,高强混凝土的抗裂性能和抗应变能力往往达不到技术要求,梁体抗裂安全系数差。本文提出采用含钢纤维和矿物外加剂DBF的混凝土浇筑铁路梁,来改善混凝土脆性缺陷,提高其抗裂、抗拉性能,从而有效避免了高强混凝土在承受极限应力时开裂,有效确保了32m超低高度梁制造技术可靠,经济可行。
