含气岩系的组成及其形成环境
,史基安,,马宝林
沉积学报 , 1995,
Abstract: 含气岩系是讨论天然气形成的地质基础,它的组成包括气源岩层、储集岩层和盖层三部分。不同地区、不同时代含气岩系的组合类型及其分布特点各异。含气岩系的形成与地质历史时期的沉积环境密切相关,最有利于形成含气岩系的气源岩层、储集岩层和盖层的沉积环境,应为海洋沉积相域的滨岸沼泽相至浅水台地相,少数在浅海开阔台地沉积环境中.陆盆沉积相域多在浅湖相,少数位于半深湖相环境中,它的生、储、盖层组合及其形成次序是形成天然气藏的决定因素。

哈拉沟煤矿井下矸石与煤置换开采探索与实践

煤炭工程 , 2009,
Abstract: 根据本井田煤层赋存条件,结合哈拉沟煤矿生产经验,详细介绍不同的排矸巷设计方案,从煤炭回采量、矸石充填量、施工工艺、经济效益等方面进行了对比研究,从中优化出符合本矿井生产实际的排矸巷设计方案,排矸巷布局、施工工艺、排矸系统都相对简单。对排矸巷进行了生产实践与应用研究之后,发现排矸巷在矿井矸石处理中的优势,而且实现了煤矿矸石零堆放,达到环保、高效、节省成本、节约土地等目标,体现了绿色开采理念,并创造出一定的经济与社会效益。设计方法及应用方案可以为类似条件的矿井提供有价值的参考和依据。

“以小说见才学者”辨正及其小说史叙述意义――兼及“才学小说”的概念使用

- , 2014,
Abstract: 《中国小说史略》专篇讨论《野叟曝言》、《镜花缘》、《燕山外史》及《?r史》四部小说并名之“以小说见才学者”时,并非基于类型归纳或文体判断而言。这些小说依旧被归入“神魔小说”或才子佳人型的“世情小说”中。鲁迅此举实为强调此类小说写作者“自寓”、“寄慨”的创作倾向,突出“以小说见才学者”创作现象于小说史的叙述意义,是其建构“从无意为小说向有意为小说演进”的小说史演进规律之目的使然。这些意图及采用列举式的评判模式,导致《史略》并未妥善处理此类小说作者创作意图与作品实际书写之间的冲突,致使“以小说见才学者”最终偏向析解作者创作意图之一面。学者将“以小说见才学者”曲解为“才学小说”等,并当作重要的小说类型,进一步偏离鲁迅本意。关注古代小说演进过程中出现的“以小说见才学者”创作现象,将比拘囿于“才学小说”从概念到概念的圈定之举更有意义。
In his Zhonguo xiaoshuo shilue中国小说史略, Lu Xun 鲁迅 devotes a special chapter to these four novels: Yesou puyan野叟曝言, Jinghua yuan镜花缘, Yanshan waishi燕山外史, and Yinshi?r史, and identifies them as novels “showing caixue才学[academic and artistic achievements] through fiction writing”. Although this identification is not based on generic and stylistic criteria and those novels are still classified into the types of Shenmo神魔novels and Shiqing世情 novels respectively, what Lu Xun really wants to do here is to highlight the commonality in the creative motivation shared by their authors who manage to get their own aspirations and feelings expressed between the lines in their novels; and is to explore the significance of these novels for constructing a history of Chinese fiction. This is the direct result from his construction of the law governing the evolution of Chinese fiction: “novels, which were started as a by-product of literary creation, become one of the professional literary pursuits.” There is, however, some tension between the rationale behind and the exemplification for Lu Xun’s identification of novels “showing caixue through fiction writing”, which is inevitably skewed towards focusing on the novelists’ writing intentions. Researchers misunderstood Lu Xun’s concept of “showing caixue through fiction writing” merely as “caixue novels”
古典目录学与鲁迅《中国小说史略》之建构
-


- , 2015,
Abstract: 鲁迅据古典目录学建构《中国小说史略》,试图将古代小说纳入当时正统文化的范围内考察,致其探讨汉魏六朝小说时以《汉志》所载的小说观为主导,对唐及唐以降的小说的探讨则采用西方文艺理论视域下的小说观。鲁迅对《汉志》“街谈巷语”以“自生于民间”的解读,试图调和中西“小说”观之间的冲突,这种做法是其承继传统的知识体系与预先做出的理论设定相冲突的典型。而古典目录学与进化论的相互交织,是鲁迅在传统思想文化的影响与外来文化的艰难抉择中处于尴尬之态的反映,亦是其采取双重小说观的必然,致使体系建构多有相矛盾之处。

Abstract: 系统梳理我国地膜机械化技术研究成果,以覆膜播种与残膜回收两大类典型机具为对象,分析对比其结构特征及工作原理,总结剖析当前地膜机械化技术中存在的问题。结果表明:在地膜覆盖机械化技术中,主要存在因苗膜错位、覆土不均、打孔成穴机构不可靠造成的空穴率高、出苗率低等问题。在机械收膜方面存在的主要问题是:地膜厚度小、强度差,增加了机具作业难度;现有机具的适配性单一,核心工作部件的可靠性不高,并且机收成堆(条)的地膜转运困难,后续处理工艺不完善,降低了农户的积极性。针对现有问题提出如下解决措施:1)研究人员在设计覆膜机具和残膜回收机具时应当与农艺相结合,改善机具作业效果及自身可靠性;2)提高我国农用塑料地膜质量,加快可降解地膜的研制。综上,加快研发优质可靠的覆膜、收膜机械是拓宽覆膜种植技术应用领域、提高覆膜地区机械化水平的重要保障。
Researches on the domestic mechanization of plastic film collection were systematically summarized in this study.The structure characteristics and working principle of two typical machines (plastic film mulching planter and collecting machine) were analyzed and compared in detail,and the existing problems in the current applied technology of plastic film mechanization were summarized and dissected.The major problems in plastic film mulching mechanical technology are high cavity rate and low emergency rate caused by the dislocation between seedling and plastic film and the uneven of soil covering and unreliable dibbling mechanism.Generally,two problems should be emphasized in mechanically collecting plastic film:Firstly,the film is too thin and the poor strength of current used plastic film increased operation difficulty in using machine.Secondly,the single suitability of existing machine and low reliability of key working component causes difficulty in transporting of strip residual plastic film collected by machine and incomplete follow-up treatment reduced farmers' enthusiasm.Corresponding solutions were proposed to solve these problems:1) To improve the working effect and reliability of machine,design of plastic film mulching planter and collecting machine should reference to agronomic requirements;2) Improve the quality of agricultural plastic film and accelerate the development of biodegradable film.In conclusion,research on and development of the plastic film mulching machine and collecting machine of better quality and higher reliability are important guarantees to broaden the application field of plastic film mulching technology and improve the level of mechanization.
