The problem of set partitions in combinatorial mathematics is conside-red, and the following three points are emphasized:(1) the non-recursivealgorithm for computing the number of partitions of an N-Set, P;(2)the algorithm for mapping the partition vector V to the partition sequencenumber D;(3) the algorithm for mapping the partition sequence number Dto the partition vector V.

本文对组合数学中的集合划分问题进行了一些探索，试图回答下面三个问题：①集合划分方法数P的非递归算法，②划分向量V映射到划分序号D的算法，③划分序号D映射到划分向量V的算法。本文以划分的构造树为基础，加以变换，得到数目树和分块树，由此求得P，以及K块划分方法数P_K。

网络数据库中的数据之间的关系不是一一对应的，可能存在着一对多的关系，这种关系也不是只有一种路径的涵盖关系，而可能会有多种路径或从属的关系。

Based on Langacker's image schema, the word "within" will be analyzed from three angles: spatial concept of "within" and its image schema analysis; the meaning of "within" mapping onto temporal domain; the meaning of "within" mapping onto target domain.

介词"within"的初始意义是："在某段距离之内，不超过某段距离"所表示的是空间位置和空间关系。

Conceptually, we present the principle of optimality for defuzzification and the optimal defuzzification mapping; methodologically, we convert the problem of finding the optimal defuzzification mapping into the one of finding the optimal parameters, suggesting a specific method for its realization—POD method; operationally, we advance that the learning of the parameters for defuzzification can be realized by the learning process using extended Kalman filter.

在概念上，提出了解模糊的优化原理和最优解模糊映射；在方法上，将求最优解模糊映射问题转化为一个参数优化问题，并提出了一个具体实现方法——POD方法；在实际操作上，我们提出可用基于增广Kalman滤波的参数学习算法来完成解模糊过程参数的学习。

These algorithms can get very high precise mapping together with high speed of convergence, because the mapping error is able to reach zero and the computational complexity is at order of polynomial.

新算法有很高的精度及较快的运算速度，这是由于映射误差可以为零，其计算复杂性是多项式阶。

To avoid the surveying and mapping information flowing along the information superhighway being an "oxcart", the realization of rapidity and automation is an inevitable tendency in the modern surveying and mapping field.

Secondly, the paper does research systematically on the basic theories of MDA, including MDA model architecture, Meta Object Facility, the mapping from metamodel to other formats and Common Warehouse Metamodel. The paper also analyzes detaily the definition, the basic rule and the characteristic of model transformation. Then a standard development flow based on MDA is put forward. The problems about parameterized mapping and partial round-trip engineering are discussed. From the discussion the most optimized method is pointed out.

其次，本文系统深入地研究了 MDA 建模体系、元对象设施 MOF、基于 MOF 的元模型到各种信息格式的映射和公共仓库元模型 CWM 等 MDA 基本理论，分析了模型转换定义、规则及其特征，提出了一个基于 MDA 的开发流程，讨论了在模型转换过程中的"参数化"映射问题和"往返工程"问题，并在多种解决方法中分析出最优解决方法。

Mean time of EA was (48.6±32.8)ms before onset of the surface QRS. The length of conduction pathway was (2.6±0.9)cm. The ablation catheter mapping showed perfect match in at least 11 of 12 leads at the EX (≥11/12), but not at the EA (≤10/12) with pace mapping during sinus rhythm. Purkinje potentials were mapped at EA and CP in all cases, but only one case at EX, and diastolic potentials were mapped at EA in 2 cases during ILVT. All cases were successfully ablated by area ablation at EA or/and line ablation at CP during sinus rhythm. None suffered a recurrence during (12±6) months follow-up.

6例ILVT周长为（286±38）ms，非接触标测显示4例激动起源位于中间隔，2例位于下间隔，EA较体表QRS波提前约（48.6±32.8）ms，传导径路长约（2.6±0.9）ms.6例病人在窦性心律下消融导管起搏标测12导联QRS形态与ILVT相匹配（≥11/12）处位于EX，而非EA（≤10/12）见正文。6例病人在室性心动过速期间消融导管于EA和CP处标测到PP， 2例于EA标测到DP， 1例于EX标测到PP.6例病人在窦性心律下于ILVT起源部位行片状或/和传导径路作线性消融均获成功，随访（12±6）月，未见复发。
