Qualitative simulation has made fruitful progress both about qualitative description and reasoning techniques since 1980s , and developed applications research among system analysis , diagnosis , conceptual design , qualitative predication , etc , 自二十世纪八十年代诞生以来，定性仿真在问题描述和推理算法方面得到了较好的发展，并在系统分析、诊断、设计、预测等领域开展了应用研究。
Although a large quantities and careful works have been done and induced disasters in tunneling , karst areas , but there still are a large quantities problems needed to be solved , due to the complicacy of such problems and the treatises are still remain at qualitative description of disasters 摘要对隧道岩溶灾害研究，前人曾做过大量细致的工作，但由于问题的复杂性，论述多停留在灾害的一般定性描述，距解决实际问题尚有较大差距。
Several methods commonly used in preparing porous silicon are presented . photoluminescence and electroluminesce ( el ) properties of porous silicon are summarized . qualitative description is given for the prevalent mechanisms proposed to explain the bright pl and el 在比较了制备多孔硅的几种常用方法的基础上，概括多孔硅的光致荧光（ pl ）和电致荧光（ el ）特性，对目前比较流行的几种发光模型给出了定性的论述，展望了多孔硅的应用前景。
The study by avis et al . 3 involving both questionnaires and repeated interviews with patients , found that the individual satisfaction scores obtained using a questionnaire were sometimes belied by detailed dissatisfactions contained in the patients qualitative descriptions of their experiences Avis在1994年的研究，采取病人问卷调查与重复面谈的方式，发现有时病人定性描述自己的就医经验中所详细罗列的不满意，竟然会否定问卷调查得到的个别满意度。

The whole thesis was made up of seven parts . the first part provided the background , significance and aims of this research ; the second part briefly reviewed the progress and the trend of the researches about the relative fields at home and abroad , then concluded that the present researches were mainly focusing on mineral cities and the qualitative description of mineral economics , which lack in quantitative analysis and utilized models ; the third part defined mineral region according to two indexes , and discussed the theoretical basis of the economic sustainable development of mineral region ; the fourth part systematically analyzed the current situation of the economic sustainable development of huangling county , emphatically discussed the coincidental relationship between mineral exploitation and economic development as well as the reasons for the recession of mineral economic ; the fifth part , , drawing on the experience of transforming industry and renewing economic in mineral cities ( region ) at home and abroad , put forth the foundation train of thought of the economic sustainable development huangling county , and programs and smocks the economic development of huangling county using the method of systematic dynamics , presented the model of the economic sustainable development of counties by comparative analysis of three plans ; the sixth part provided some policed suggestion and measure for the economic susta inable development of huangling county 全文分为七个部分：第一部分：提出研究的背景、意义与目的；第二部分：简要回顾了国内外相关领域的研究进展与趋势，指出当前研究主要集中在矿业城市与矿业经济的定性描述，缺少定量分析和应用模型；第三部分：依据两组指标界定矿业区域，探讨矿业区域经济可持续发展的理论基础；第四部分：对黄陵县域经济可持续发展现状进行系统分析，重点探讨了矿产资源开发与经济发展的耦合关系及其矿业经济衰退的原因；第五部分：在借鉴国内外矿业城市(地区)产业转型与经济新生经验的基础上，探讨了黄陵县域经济可持续发展的基本思路，并运用系统动力学方法对黄陵县域经济发展进行规划与模拟，通过三种方案的对比分析，提出县域经济可持续发展模式；第六部分：黄陵县域经济可持续发展的政策建议与措施；第七部分：主要结论及进一步研究的问题。
The soil - nailed support system has been applied widely at home and abroad , but it is short of research on mechanism of interactive action between support structure and rock and soil medium especially soft - weak medium and some understandings rest on the stage of qualitative descriptions . current design theories base on engineering analogy . the systemic numerical tests on soil - nailed support are made utilizing the advantage of the fem method on quantitative research in this dissertation , the reinforce mechanism in quantitative aspect is pointed out , and the reinforce effects of support parameter and soil property parameter are abstracted so as to provide scientific basis for optimization design 土钉支护在国内外已得到广泛应用，但对支护结构与岩土介质特别是软弱岩土介质相互作用机理的研究还停留在定性描述阶段，现行设计理论只能建立在工程类比基础之上；本文借助有限元方法在量化研究方面的特有优势，对土钉支护进行了系统的数值试验研究，试图从量化的角度揭示土钉支护的加固机理，为优化设计提供较为科学的依据。
Some issues will require qualitative descriptions of your approach and performance against the issue and others will involve measurable performance indicators . after you have assessed your overall performance , it is time to identify where improvements can be made and where you can set objectives and targets for inclusion in the report 你可说明部门政策局机构处理某些事项的手法和表现，给予质素上的评价，如有关的环境工作表现可以量化指标来评估，则可提供这类实质数据。
Because of the complexity and particularity of evanescent waves , a pure theoretical treatment can only provide a qualitative description , a well - developed 3d em code , sos6 which is based on the magic command language with the finite difference time domain method , is used to simulating the em evanescent waves in this article 由于消失波的复杂性和特殊性，难已进行解析理论分析，为此，本论文采用基于时域有限差分方法的3d电磁场分析软件对消失波的特性进行模拟分析。
Transcription of tape - recordings of 17 courtroom trials amounting to more than 900 , 000 words was used as data , of which questions and responses were identified and then studied and analyzed within a framework which draws insights from speech act theory , discourse analysis , conversational analysis and corpus linguistics , with focus on qualitative description supported by quantitative analysis 结论是： （ 1 ）问答是法庭审判的主要进行方式，因此从问答着手研究法庭话语具有重要价值。 （ 2 ）问的最多的是法官，因此，研究中国的法庭审判不能不重视对法官话语的研究。
