In conclusion, the algorithm has an important application in prophase of compiler development It can free programmer from repeated and tired manual transformation and avoid unnecessary energy waste.

本文提出的转换算法在编译器的开发前期有着比较重要的应用，应用算法进行非递归下降文法的自动转换，可以将开发人员从繁琐的手工转换中解脱出来，避免了不必要的精力浪费。

Subsequently, through the dynamic mechanisms of investment, the endogenesis of price, consideration of the resource constraints and the alternativity between productive factors, this paper completed the historic simulation to update key data, then built the closure criteria for baseline simulation, combined the dynamic recursive methord, finally assessed the long-term impact for member states in terms of policy changes under 4 scenarios. Different to the analysis from perspective of comparative static, the assessment of long-term economic impact was started from the macroeconomic point of view and import and export trade to reflect the relationship between short-term influence and long-term impact under 4 kinds of possible policy changes.

首先从CGE模型传统的比较静态的框架下，就GDP、贸易规模、双边贸易、贸易结构及产出水平、国民福利等方面来阐释各政策情景产生的冲击效果；然后通过投资动态机制与价格的内生化，考虑资源限制及生产要素间的替代性，以逐年递归动态求解方式，分国别从宏观经济、进出口贸易角度出发，对于成员国在政策变动后可能产生的远期影响进一步做出评估，以此来反映各种可能的政策变动对成员国经济的短期影响与长期影响之间的关系。

In this paper, first we define a kind of transformation on the sequences of Boolean functions, and then analyze the changes of nonlinearity, algebraic degree and balancedness of Boolean functions under the transformation.

本文首先定义了对布尔函数的序列的一种变换，并分析了进行此种变换后布尔函数的非线性度、代数次数与平衡性的变化情况，最终在此基础上提出一种新的递归构造方法，可以构造出非线性度很高的n元m阶n-m-1次弹性函数。

Applying RQA, we analyse the EMG of biceps brachii muscle and brachioradialis muscle under different loads, point out the percent recurrence of brachioradialis muscle is higher than that of biceps brachii muscle and more periodic.

最近由Eckman等［1］提出的递归图示法（recurrenceplot，RP）以一种简单的图形显示出了其在表征系统动力学特征方面的优点，被证明是一新的非线性分析的有效工具，引起了人们极大的兴趣。

As it can be expressed easily by argument equations, we use the conicoid as the criteria of points" classification. Based on the point"s normal and the adjacent field, corresponding to the conicoid equation such as plane, ball and cylinder, we search the points that fit the equation along the adjacent field. Using this method, we realized the automatic classification of unorganized points.The experiments using the algoritlim and criteria approved from this thesis are also carried out.

本文采用了可以比较方便地用参数方程表示的二次曲面作为数据点的分类标准，根据点的法向量以及其邻域结点的各种属性，对应于平面、球面、柱面等二次曲面，依据曲面方程的特点，从起始点开始沿邻域深度优先递归寻找符合方程的数据点，实现了散乱数据点的自动分类。

Re-vectorization is performed on the basis of original vectorization by obtaining the initial parameters such as line types and slope. Inuring tricing it can adjustthe parameter adaptively. To decrease the influence of noise pixels, we designed a stop probe to detect tracing-stop conditions. Process of re-vectorization is performed recursively until quality of graph entity is satisfactory.Finally, some key technologies for 2D graphs reconstruction are studied. The issues concerned include the recognition and presentation of topologic relations among graphs entities and a directed and weighted graph model established to describe the relations and techniques on dimension driven.

在获得对图素识别质量的评价之后，质量较差的图素被输入到错误自动校正器进行错误校正处理，本文提出&二次矢量化&的错误校正思想，二次矢量化是在初步矢量化所获得知识的基础之上，取得初始参数，并在跟踪过程中动态校正参数，在跟踪结束时引入跟踪终止检测探针以消除光栅图像中黑白噪音的影响，使得算法具有较强的抗噪音干扰能力，校正后的图素仍需进行质量评价，未能通过评价的图素需递归执行二次矢量化算法。

Their messy, recursive field of causality, of every part being both cause and effect, makes it difficult for any part of the system to make routine linear extrapolations into the future.

它们所具有的那种混乱的、递归式的因果关系，各个部分之间互为因果的关系，使得系统中的任何一个部分都难以按照线性的方式去推断其未来的行为。
