Journal of hydrodynamics 1993年第4期5卷 57-62页

作者： t.ohta h.yamauchi m.toriumi engineering research center,nkk corporation,kawasaki,japan

the structural failures of jack-up rigs were mostly found in leg structures,due to cracks in way of connections between tubular members of leg ***,stress calculations of leg structures can be made by using“finite element techniques”,it takes a lot of time to complete the calculations for the full cases of all working conditions because of many tubular ***,a simple method for the stress calculations for design purposes is strongly *** paper desribes a simple stress calculaiton method of leg structures and shows a satisfactory results as compared with the results obtained by a detailed calculation method.

自 1976 年以来,日本核废料管理基金会与研究中心(RWmC)一直在进行核废料处置的研究。最近,RWmC非常关注核废料处置库的监测、遥控以及现场勘查技术等重要的社会公众与技术问题。其中,处置库溢出气体是一项重要的安全可靠性评估项目。这项名为“工程屏障的气体渗透试验”(Gmt)的研究是在瑞士 Nagra 的 Grimsel现场实验室进行的。Gmt 集中研究在粮仓形的处置库中由核废料产生的气体在工程屏障中的渗透问题。在 Grimsel现场,一个按比例缩小的工程屏障库由一个具有透气孔的混凝土仓和砂–膨润土缓冲材料组成,缓冲材料被放置在一个专门建造的洞室中。混凝土仓直径为 2.5 m,高为 2.5 m,放置在直径为 4 m 的从上到下开挖而成的竖井中。在工程屏障饱和及水渗透试验之后,气体分两个阶段被注入地窖中。气体第一次被注入之后,重复进行水渗透试验,以便观察工程屏障库的变化。第二次气体注入的时候,在工程屏障及岩石圈中采用一种可以多点取样的鸡尾酒气体跟踪器。在气体注入之后,小心挖掘出工程屏障库,然后用各种方法来进行鉴定,并采用实验室以及建模程序来进行现场的模拟研究。

Inherent metallic species retained by coal char or coke,such as Na and Ca,behave as catalysts in *** char/coke normally contains inherent SiO_(2),which can react with the inherent catalysts to form silicates,resulting in catalyst deactivation over the range of pyrolysis,carbonization and gasification,and thereby reducing the char/coke *** present authors simulated the inherent catalyst deactivation experimentally by blending a Victorian lignite with SiO_(2),briquetting the SiO_(2)/lignite blend,carbonizing the briquette,and then gasifying the coke with CO_(2).the kinetic analysis of the gasification employed a comprehensive model,which assumed progress in parallel of non-catalytic and catalytic *** model quantitatively described the measured kinetics of the coke gasification with different SiO_(2)contents over a range of coke conversion up to 99.9%.the kinetic analysis revealed that the SiO_(2)deactivated substantial and entire portions of the most active catalyst and its precursor,respectively,before the gasification(i.e.,during the carbonization).the catalyst deactivation also occurred during the gasification,but mainly following a self-deactivation mechanism that involved no silicates formation.
