| | The Quaternary strata, outcrop quite completely and clearly in Qianhu Section, containsome special strata such as the carbon sediment, the iron hardpan, the heavy mineral sandygravel layer, the"Old Red Sand" and the basalt. It is a typical outcrop to study the Quater-nary geologic questions along the coast of southern Fujian. By a comprehensive analysis ofdatinges, microfossil, sporo-pollen assemblages, mineral composition and granulorpetric fea-tures of a series of samples from this section, th... | | 前湖剖面第四系出露比较完整,层次清晰,发育有炭质层、铁盘、重矿砂砾石层、“老红砂”层和玄武岩等特殊地层,是一个研究闽南沿海第四纪地质问题的比较有代表性的地表露头剖面。本文通过对前湖剖面中系列样品进行测年、微古、孢粉、矿物、粒度等综合分析研究,探讨了闽南沿海晚更新世晚期以来的古气候变化、海平面变动、“老红砂”的形成年代及成因以及第四纪地层划分等问题。 | | 文摘来源 | | From the sample of silica bricks in coking chamber of coke oven which had been running over 15 years,the microstructure of silica bricks were analyzed by SEM.Compared silica bricks on the side of coking chamber and the side of combustion chamber with new bricks,the damage of bricks in coke oven which had been used over 15 years were studied.The main reason of the damage of silica bricks in coke oven was that the carbon sediment of the pores and flaws in the silica bricks which resulted in the ch... | | 对已使用 15年的焦炉炭化室硅砖进行取样和扫描电镜分析 (SEM ) ,通过炭化室侧、燃烧室侧与未使用硅砖对比分析 ,进而分析使用后硅砖的变质情况与规律 ,认为硅砖的损坏主要是焦煤炭化产生的气体的窜漏、碳粒在气孔和裂纹上沉积导致的显微结构变化所造成的 | | 文摘来源 | | The experience cleaning carbon sediment inside saturated oil tube of crude benzene tubular furnace by using chemical method of adding gas and gasified burning is introduced.The analytical result of the sample for carbon sediment inside abundant oil tube,the cleaning mechanism,the concrete cleaning operation procedure and the result of adding gas and gasified burning are fully expounded. | | 介绍了采用加气气化燃烧的化学方法,清洗粗苯管式炉富油管道内壁碳渣的经验,对富油管道内壁碳渣的垢样分析结果、加气气化燃烧的清洗机理、清洗的具体操作过程及取得的效果作了全面的阐述。 | | 文摘来源 | |   |
