In this study, we adopt a Gauss-Markov hyetograph. We also propose a new approach for selecting regionalized representative design storm hyetograph in northern Taiwan. By combining the principal component analysis and cluster analysis techniques, we select five principal components and group design storm hyetograph into three categories in the study area. Finally, we employ the method of analytic hierarchy process to establish the regionalized representative hyetograph for northern Taiwan area.
本研究针对台湾北部地区提出一个新的方法来评估并建立区域代表雨型,首先选取各测站具尺度不变性之高斯马可夫雨型,其次利用主成份分析法萃取出雨型中的五个重要成份,并以群集分析法将研究区域内之设计暴雨雨型分为三个均匀群集,但同一群集内之雨型并非唯一,故研究中最后利用层级分析法进行评估,选取并建立出区域代表雨型。

We have successfully synthesized hydrocarbonbearing inclusions in carbonate at the temperature and pressure of 150 ℃ and 40 MPa, which are near the condition of natural reservoir underground 4 kmAll synthetic hydrocarbonbearing inclusions have been analyzed by microscope and microfluorescence and fourier transform infrared spectroscopyThe results show that the synthesized hydrocarbonbearing inclusions are very similar to those in real reservoirsOur experiments give us four important insights, including:(1) immiscibility of oil and water is the main reason for hydrocarbonbearing inclusions and aqueous inclusions distributed in different fractures;(2) rapid accumulation of oil and gas can be recorded by fluid inclusions;(3) the study of synthetic hydrocarbonbearing inclusions at the temperature and pressure of real reservoir will offer references and standards for the analysis of fluid inclusions in reservoirs;(4) experiment of synthetic hydrocarbonbearing inclusions is a good method for understanding the mechanism of oilwaterrocks interreaction in reservoirs.
文中报道在实际储层温压条件下(150 ℃,40 MPa,大约4 km深度)成功合成了碳酸盐岩烃类包裹体。通过对合成烃类包裹体的显微观察、荧光分析和傅里叶变换红外光谱分析,证实合成了烃类包裹体,且与真实储层中的包裹体具有相似特征,探讨了油水不混溶条件下的流体包裹体捕获机制。实验研究给出4点重要启示:(1)油水不混溶是造成烃类包裹体和水溶液包裹体分带的主要原因;(2)油气快速成藏过程可以被流体包裹体记录;(3)实际储层温压条件下,合成烃类包裹体实验研究有望为储层包裹体分析提供依据和标准;(4)人工合成烃类包裹体为研究含油气条件下储层水岩作用机理提供了一种有效手段。

But it also exposed that the concept and aim of IM are indistinct, and there were shortages in interpretation TCM by WM and lack of deep research in methodology. Therefore, up to now IM only localized in clinical diagnosis and treatment, but not in theory and thought. The modes of TCM and WM have aspect of difficult intergradation, and aspect of easy one that is the growth and integrated point for IM.
由毛泽东主席亲手拉开的中西医结合序幕,经过四十多年的努力,从辨证与辨病、治愈机制和理论几个不同层面分别进行了结合研究,在基础理论研究,特别是在提高临床疗效方面取得了可喜的成就,但同时也暴露出对中西医结合概念和目标认识模糊,存在着以西解中、方法论研究缺乏力度等不足,从而造成了至今中西医结合主要局限于临床诊治层面,在理论、特别是在思维方式层面上,中西医尚处于结而未合的状态。

In a comprehensive study of various macro-and micro-heterogeneous reservoir parameters on the basis of the reservoir quality, we launched a comprehensive evaluation to determine the evaluation criteria. The reservoir quality in 2+3 was divided into three types. The research shows that distribution of interlay and insulating layer is controlled by sedimentary microfacies. The developmental stages and the size of the sedimentary microfacies determine the plane and the vertical distribution of interlay and insulating layer.

At first, this paper surveys nonlinear control and the applications of neural networks in control respectively. Then it studies definitions, mathematical descriptions and conditions of invertibility for nonlinear systems, which are used to analyze the feasibility of inverse system control method. Conclusions about the feasibility of inverse control and the realizability of αth-order inverse systems in engineering are achieved. Furthermore, this paper discusses the feasibility, structure and identification of neural network αth-order inverse system for general single-input single-output continuous or discrete nonlinear systems and various composite control methods based on the αth-order inverse. At last, as a part work of an actual project, this paper focuses on the design of neural network αth-order inverse control method for thyristor controlled series compensation in power systems and its effect in improving the stability of power systems.

As for the case study, the author finds one friend with the jealousy personality to be the subject. After the case had seen ten movies, including Hemlet, The kid, As Good As It Gets, The Crucible, A Simple Plan, Beyond Silence, Shine, American Beauty, Eyes Wide Shut and Lantana, he will share the thoughts about those movies with some questions. The effects of this research could be explained by two parts. One is to analyze the case's jealousy features and its causes. The other is to discuss the case's mental change by the displacement of roles and catharsis of emotions.
