These nonlinear chaos dynamitic models forecast oil consumption quantity of China. In this dissertation, it has mainly studied the fractural dimension measure to petroleum economics system, the phase space reconstruction modeling and prediction techniques to economic chaotic time series. It puts forward chaos dynamitic models, which are forecasting model for oil consumption. Corresponding countermeasures of the oil supply-security of China are suggested by analyzing the forecasting results and the problems existing in petroleum economic system of China, especially aiming at the balance between oil production and consumption quantity.

Dynamic cutting force is a basic parameter and it directly influences relative displacement between tool and workpiece, tool wear and surface quality in turning operation. Therefore, simulation model of dynamic cutting force is an important part of machining physical simulation research. Cutting force models commonly used are empiristic equations. These equations are often based on statistical analysis of machining data, obtained via changing one or more machining parameters, whilst fixing others. But a complete turning process and nature of force can not be accurately described by means of these models.

动态切削力是切削加工过程中的基本参数，其动态变化直接影响加工过程中刀具与工件的相对位移、刀具磨损和表面加工质量等，因此动态切削力的预测仿真建模是切削过程物理仿真研究的基础，但是目前大多使用经验公式描述动态切削力，这些经验公式多少存在一些不足，难以完全真实地反映在整个切削过程中力的变化历程和变化特点。

Based on them, this paper proposes evaluation indexof fund performance from the aspect of finance, investor and interiormanagement. Considering the limitation of data envelopment analysis approach usedto evaluate fund performance, such as conventional DEA models can not considerinputs and outputs of evaluation units simultaneously, and an input-oriented DEAmodel and output-oriented DEA model often produce different evaluation results,this paper proposes a general form of DEA model which is input- andoutput-oriented by using multi-objective optimization and fuzzy set theory. Sincethe general form of DEA model can be transformed into a conventional input oroutput oriented DEA model by using special membership functions, it can beseemed as a nature extense of conventional DEA models, and a conventionalmodel can be regarded as a special case of DEA mdoel with general form.

针对现有基金绩效评价方法中较具优越性的数据包络分析方法的不足，如传统DEA模型不能同时综合考虑评价单元的输入和输出，以及分别采用面向输入和面向输出DEA模型评价基金绩效时，常常出现不一致的评价结果等，本文以多目标优化与模糊集合理论为工具，提出了一种能够同时面向输入和输出的DEA一般形式模型，并通过选择一些特殊的模糊集合隶属函数，使得这种DEA一般形式模型成为传统DEA模型的自然推广，而传统DEA模型是该模型的特殊形式。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
