定性数据

So the method has the characteristic of brachylogy and speediness. It not only can qualitative and also calculate quantitative the position of field source; It can draw availably the basic outline of anomalies source.

该方法具有简明、快速的特点，它不仅可以定性、同时可以定量地进行场源位置的计算，可有效圈出异常源的基本轮廓，所以较其他方法可更广泛地应用于更多的地质情况，尤其适合大面积位场数据的分析和解释。

At the same time, in view of some deficiency of traditional modeling methods, a new approach to system modeling梞ultiresolution modeling and aggregation/disaggregation梙as been developed since 1980s,and is now being used in the simulation and optimizing decision-making for large scale complex systems.

复杂系统的仿真和优化控制是以建立对象合理而准确的数学模型为基础的，但复杂系统本身具有一定的复杂性，对其进行建模和仿真时，会存在大量不同模式的信息数据(定量的、半定量的、定性的)，它们从不同角度不同层次反映系统的行为，而且往往具有不同的粒度和分辨率，传统的建模方法不能满足复杂系统的要求。

More recently, user research has expanded to include qualitative, ethnographic data.

再近一步，用户调研被拓宽到包含定性的，地域的数据。

The main work and innovation of this dissertation are: 1. The network management domain-specific mobile agent system architecture and mobile agent model are proposed and described in details. The lifecycle of mobile agent is described by using state diagram. The layered security model is introduced. The mobility model is distinguished by the complete and partial one as well as the explicite mobility and implicite one. 2. Aimming at the complexity and heterogeneity of the network, the abstract network entity is presented and defined in details. The mobile agent is also classified and studied from the point of the mobile mechinisim along with the resposibility view. The NMBMA, which the main component is ANE, is put forward and described by using organizational, informationl, computational and implementary model. 3. The two architectures, NMBMA and Client/Server-based one, are compared and analyzed quantitatively and qualitatively. 4. The prototype based on the above NMBMA is designed and some examples are described in the prototype.

The inversion of particle size distribution from measured data of light scattering, as a typical inverse problem, has been studied by many reseachers and solved by several numerical methods. Among which, direct Tikhonov regularization method with Morozov discrepancy principle, is often used to overcome the ill-posedness linked with the Fredholm integral equation of the first kind, so the stability of inversion has been heightened. But there has much room for improvement of the inversion accuaracy, especially for the double-peak problems.

由测量得到的散射光强数据来反演颗粒粒径分布是一个典型的反问题，它已为许多的学者所研究，并用多种数值方法来求解，其中带Morozov偏差原理的直接Tikhonov正则化方法经常被采用，以便用来克服与上述反演相联系的第一类Fredholm积分方程的不适定性带来的困难，因而反演的精度得到了提高；然而仍有许多改进的余地，特别是对于所谓"双峰"问题更是如此。

Firstly a qualitative criterion for determining the space between adjacent sections in the sampling process and Gaussian smoothing algorithm is proposed. Then a topological reconstruction method is given. At last a new reconstruction method based on the similarity between adjacent sections is proposed.
