公路隧道塌方诱因及处治技术研究

众所周知,隧道属于线状隐蔽和穿越性的工程项目,在具体的施工过程中会穿过崇山峻岭,经过诸多岩类,其结构具有较大的不稳定性特点,而围岩又是隧道在开挖过程中极易遭到破坏的对象,这也是对其进行支护的主要原因。唯有如此,才能有效避免公路隧道塌方事故的出现。由此可见,探讨公路隧道塌方诱因及处治技术具有极其重要的现实意义。     

Non-Invasive Measurement of Brain Neurotransmitter： One Novel Model

Brain sciences require tools that can noninvasively measure the blo-energy of Brain neurotransmitters （BNs）. First we review the key models behind these tools, then to report one novel model OIIWA on otopoint＇s infrared image and wavelet analysis. Based on our model we provide a new investigative tool probe with 10-order wavelet coefficients corresponding to BNs in mHz level fluctuating, at last to select the medicament inducement as validity experiments for verifying the accuracy through the brain window of OIIWA. The data come from 10-subjective confirmed that our model validity be 90%.     

Evolution of the linkage structure of ICT industry and its role in the economic system: the case of Korea*

ABSTRACT

When assessing the structural role of an industry sector within an economic system, considering its relationship to other sectors is crucial. Among others, Information and Communication Technology (ICT) industry, one of the innovation accelerators or key engines of economic growth, is evaluated. Specifically, we analyze inter-industry production inducement linkages within a qualitative input–output analysis framework, since it is useful for understanding the key structure of an economic system. Our purpose is to understand the significant spillover structure of the Republic of Korea’s ICT industry within the national production system, as it has played an important role in the national economy and grown dramatically over the years. The findings from the structural analysis, focused on changes in links, are as follows: First, ICT manufacturing showed a higher degree of heterogeneity than ICT service sectors in its sensitivity effects structure, an indication that this sector needs to be utilized in various other industries. Second, the spectrum of industries having significant production inducement linkages with the ICT industry is limited and furthermore, the influence effects of the ICT manufacturing sector diminished considerably although the ICT industry’s sensitivity effects increased. Finally, intra-industry linkages within the ICT industry are gradually strengthened especially between ICT services and manufacturing. These findings call for sustained policy efforts to promote the virtuous circle in the overall inter-industry production inducement system, by increasing the utilization of products and services from other sectors by ICT sectors (especially ICT manufacturing) as well as the application of ICT in other sectors.     

原板夹杂物诱发镀锡板点腐蚀缺陷分析

原板高强减薄和锡量降低是镀锡板发展的重要趋势,直接对原板夹杂物和镀锡板表面缺陷控制提出了更为严格的技术要求。通过对夹杂物含量异常的钢坯进行全流程加工得到的1.1/1.1 g/m2规格镀锡成品卷的研究,发现经过10 d在库测试,镀锡板表面产生点腐蚀缺陷。利用光学显微镜、扫描电镜和电子能谱等方法就镀锡板点腐蚀缺陷进行了深入分析,结果发现黄褐色腐蚀产物元素成分为O、Fe,源于基体腐蚀,并伴有原板夹杂物存在。通过金相切片确认典型点腐蚀缺陷样品夹杂物尺寸为96.82μm×50.00μm×8.86μm,属于原板表面嵌入型夹杂,其成分特征为主要含Al、O元素。夹杂物的存在改变了局部区域的原板轧制纹理和镀层形貌,产生近似椭圆白点缺陷,锡层沉积量由缺陷中心外延逐步增加,整体在11.02%～28.08%范围内波动。根据夹杂物伴随点腐蚀缺陷特征,其诱发镀锡板腐蚀行为与夹杂物形成的原板晶体结构缺陷、锡层差异沉积与夹杂物导电性和硬度直接相关。通过研究,清晰地描述了原板表面夹杂物对后续镀锡板成品的表面质量影响关系,为更好控制原板夹杂物提升镀锡板产品表面质量提供了实际数据支撑。     

“三农”视角下工商资本与农村职业教育的结合

解决"三农"问题首先必须要大力培育农村发展元素并使之成熟完善。注入工商资本于农村职业教育可为工商资本多渠道投资农村建设提供科技、人才、管理等支持,在明确的农村建设目标下,做到教育与生产相结合,人才培养与市场需求相结合,可推进农业现代化、产业化,实现农民增收、农业增长、农村稳定。

合成瓦斯水合物诱导时间的研究

通过研究利用模拟瓦斯合成瓦斯水合物的诱导时间,以寻找缩短诱导时间的主要因素.结果表明：分别使用SDS（十二烷基硫酸钠）,SDBS（十二烷基苯磺酸钠）及吐温-80等表面活性剂可在煤矿井下温度和中高压的条件下生成瓦斯水合物,同时使用已融化的水合物进行重复实验可显著缩短诱导时间;而且温度越高,诱导时间越长.     

反垄断法产业诱导机能的现实意义--兼论产业诱导机能在未来中国反垄断法中之具体体现

反垄断法具有维护自由竞争和产业诱导两大机能,但遗憾的是,产业诱导机能一般不受重视,在学者的研究中鲜有提及。其实反垄断法带有极强的政策倾向性,各种产业政策无不体现在反垄断法实施中。从解释学角度看,产业诱导机能具有广泛的现实意义。首先,全球范围内反垄断的发展趋势需要产业诱导机能。其次,中国的经济现状也亟待反垄断法的产业诱导机能加以解决。此外,通过假设与实证相结合的研究方法,还对产业诱导机能在未来中国反垄断法中的体现作了详细规划。
