It provides a way to find optimal lower dimensional approximations of the given data, and It enormously reduce the storage of the data which is needed when the physical processes is recurred. The physical process can be described in series expansion function that only is related to the time and space. It is optimal approximation of the given data in a certain least squares optimal sense. The most obvious advantage of the method is that it reduces the computation cost and computation time markedly.

它提供了一种描绘物理过程的有效方法，该物理过程可以写成一个只与时间相关的函数和一个只与空间相关的函数的展开式序列，且它们在均方意义上是最优的，在展开式中只需要少量的项数就可较准确地描述该物理过程，因此降低计算维数、减少计算量和节省计算时间是这个方法最明显的优点。

Expansivity, contraction, rebirth and vanishment events for management of land use data. And it further designed an object-superposition data updating model based on the land use feature of point, line and polygon,which would take the advantage of the GIS overlay function to effectly implement of updating spatial and attribute data .

从面向对象的方法入手，定义了引起土地利用变化的扩展、收缩、新生与消亡四种地理事件，并分别按点状地物、线状地物和面状图斑的土地利用实体特征设计了对象叠加更新模型，从而能利用GIS强大的空间分析能力，来有效地实现空间数据和属性数据的一致性更新。

In this paper the structure principle of GM(1, 1) was analyzed and the defect was pointed out that the traditional model only adapt to the data with exponential law, and only can fit for the monotonic data. The prediction is defected when there are two consecutive data unchanged, and 'a' is equal to 0.5 in prediction formula.

从传统GM(1，1)预测模型构造原理出发分析其存在的理论缺陷，此模型适用于具有较强指数规律的序列，只能描述单调变化过程，而且预测数据序列中出现连续两个相等值时将使得a等于0，会使预测数列发散致使预测失效。

Above all, we take color part mediumly to do a specification to the graph, the small rectangle that brings facial expression is representing the communication port that can be sent and receives broadcast data package, have ' S ' the expression of the mark this port basically sends broadcast data package outwards, have ' R ' state this port receives broadcast data package only.

首先，我们对图一中的带颜色部分做一个说明，带颜色的小矩形都代表着能发送和接收广播数据包的通讯端口，有'S'标志的表示该端口主要向外发送广播数据包，有'R'表示该端口只接收广播数据包。

Through detailed analyzing some influencing factiors of sand liquefaction, seven parameters were selected as assessment indexes. They are earthquake magnitude, peak ground surface acceleration, standard penetration value, specific penetration resistance, relative compaction, average particle diameter, and water table. The extension assessment model has been established that was applied to assessment of sand liquefaction potential. The model had been trained by the historical data and has been assessed in virtue of sand liquefaction from the historical data by simulating, and got a excellent result. After introduction of the support vector machine theory, this paper established the assessment model of sand liquefaction based on the support vector machine, and assessed in sand liquefaction from virtue data of some fields in home and overseas with the tool Libsvm, which was programmed based on the support vector machine theory. And got a good coherency between the assessement results and the actual liquefaction.

在详细分析影响砂土液化因素的基础上，选取了震级M、地面最大加速度g_、标准贯入击数N_(63.5)、比贯入阻力P_s、相对密实度D_r、平均粒径D_(50)、地下水位d_w等7个参数作为评价指标，建立了砂土液化势的可拓评价模型，并对历史数据进行仿真评价，取得了较好的应用效果；在对支持向量机的理论进行介绍后，本文建立了基于支持向量机的砂土液化势评价模型，并利用在基于支持向量机理论的Libsvm软件，对若干国内外场地的现场实测数据进行了评价，评价结果与现场表现基本上一致。

To the disadvantage exposed to us in national and foreign VTS system, and those putted up in application projects, the thesis did a farther study and consummation, and acquired some research fruits, as follows:1. Fulfilled the Eagle Eye function in Electronic Chart Display System.2. Designed a kind of simple algorithm for select chart. By this arithmetic it become true to auto select electronic chart when chart is zoomed.3. The realization of auto acquired field on electronic chart.4. The simulation of target data and error of radar and AIS by software.5. The fusion processing of the dynamic data those are collected from AIS and Radar.6. Resolve the target track problem of radar by the data fusion technology.7. The algorithm design of display field reduce, this function can improve the speed of display.
