基于关中村落中农用性器物价值与保护策略研究

界定了器物的研究范畴,归纳出农用性器物的特征及代表。论述了国内外研究由物质遗产向非物质遗产的转变过程、政策支撑与保护发展的历史走向,解读了传统村落农用性器物的社会价值、历史价值与文化价值之间同聚落文化的纽带作用,反思了当下关中村落农用性器物所面临的文化地域性缺失等问题,通过对历史研究提出了直接式保护策略、间接式保护策略和环境式保护策略,以资旨在重新审视器物在当代社会所赋予的乡土使命。

古新丝路视域下的中巴伊土国际通道文化价值研究

中巴伊土(中国—巴基斯坦—伊朗—土耳其)国际运输通道作为"设施联通"的先行者,是"丝绸之路经济带"的重要骨架,其实质是对古丝绸之路的传承与发扬,研究该通道的文化价值有利于从文化的视角挖掘交通通道的软实力。东汉—贵霜—安息—罗马与中国—巴基斯坦—伊朗—土耳其在古新丝路上交相辉映,故而通过古新丝路的对比,从通道的器物文化价值、制度文化价值、载体文化价值三方面剖析通道的文化价值,既可以借古明今,又可以继往开来。

仿制石权杖头的实验考古及相关问题探讨

实验考古是了解人类早期技术过程的重要途径。对出土遗物的模拟复原实验可以帮助我们理解其制作过程及能量消耗。本文通过对石权杖头的实验仿制,重建了此类器物的制作技术和工艺流程,包括原材料选取、各类工具的使用,获取了制作此类石器消耗时间的量化指标,为理解石器加工技术流程和器物价值体系提供了参考。

Converting of MSW into Valuable Hydrocarbons by Pyrolysis： Effect of Paper/Plastic Ratio and Reaction Time

Municipal solid wastes from industrial plants were pyrolyzed in a fixed bed reactor to evaluate the influence of paper/plastic ratio and reaction time both on product quantity and quality. Raw materials have been pyrolyzed under nitrogen in a 3.0 dm^3 autoclave. Results show considerable differences in yields and quality of products obtained by pyrolysis of wastes with different paper content. Light and heavy oils were mixtures of organic compounds containing valuable hydrocarbons and oxygenated chemicals, while chars were rather composed of inorganic compounds from the raw materials. Longer reaction time of pyrolysis had produced higher non-condensable gas, water and light oil. Gases contained CO, CO2 and hydrocarbons, but the concentrations were very function of reaction time and paper/plastic ratio. Light and heavy oils showed similarities with middle distillates and heavy oils in refinery, the high paper content of the raw materials was unfavourable for longer storage of waste derived oils.
