This thesis consists of two parts. The first one was that boundary value problem was discrete with five point difference method. Three kinds of memory formats were studied, which were full matrix, half band width and row compress sparse. Full matrix memory format and half band width memory format first was contrasted. The results show that half band width has efficiency in space. Then the algebraic system of finite element method was solved by Gauss-Seidel iteration method to popular row compress sparse memory format.

本论文由两部分组成，第1部分针对边值问题，用5点差分格式进行离散，并对离散矩阵这类大型稀疏矩阵，研究了系数矩阵的3种存储格式的优劣，即：满矩阵存储格式、半带宽存储格式和按行压缩稀疏存储格式，首先我们将满矩阵存储方式和半带宽存储格式进行了对比，迭代法的数值实验表明：利用半带宽存储的矩阵在空间运算方面具有高效性；然后针对目前数值实验中流行的按行压缩稀疏存储格式，实现了有限元离散代数系统的迭代法的求解。

Using varied band matrix and one-dimension array to collect the large sparse matrix, the integral coefficient of all the nodes, we could save memory space.

采用变带宽、一维数组方式只存储稀疏刚度矩阵中非零元索，能够节约内存。

You may WANT gigs of space and bandwidth, but do you really NEED them.

您可能会想要演出空间和带宽，但你真的需要他们。

If not, do not waste money paying for bandwidth and storage space that will not be used.

如果没有，不要浪费钱支付带宽和存储空间，这将不会被使用。

In transforming Sir Giles Gilbert Scott's Bankside Power Station into a pristine space for contemporary art, Swiss architects Herzog and de Meuron lit a match that kindled a British love affair with modern art.

泰特现代由一座旧电站改建，重新赋予它生命的瑞典建筑师 Herzog 和 de Meuron 借此点燃了英国民众对现代艺术的热情。

Finally, the study primary indicate three ecological zone ,named urban core zone, urbanize zone, banlieue, and defined itself ecological relationship. Simultaneity, this syudy indicate cardinal urban space development problems about population, land, economic activities by the spatial structure analysis. And it directs this problems to offer countermeasure.

进而利用台中市相关数据初步地辨识出都市中心、都市化地区及市郊区等三个都市生态空间区域，指出其生态关系，并透过空间结构分析明确台中都市发展在人口、土地和经济活等三方面的主要问题，从环境保护的角度，对台中都市生态系统空间结构的问题提出改善建议，供台中都市空间规划参考。
