本論文以城市交通規劃為背景，對城市交通規劃時空數據模型的設計方法進行了討論，提出了一個城市交通規劃時空數據模型。論文著重對交通規劃基礎信息面狀要素、線。 。 -
Basing on key concepts and techniques in object - oriented modeling, the thesis discusses design of object - oriented spatiotemporal data model, and entirely defines and describes spatiotemporal object types that are of concern in a stdm. organization of temporal attribute data and temporal treatment of spatial object are described. spatiotemporal object operators and spatiotemporal index are logically designed
論文對模型的時態屬性數據組織和空間對象的時態處理進行了描述，提出作為節點和弧段，空間位置和范圍是它們的本質屬性，所以只要節點和弧段的空間位置和范圍發生變化，則節點和弧段發生生亡事件。 -

First, this paper introduces the conception of software test, testability, and some existent model used for analyzing testability. second, we analyze the merits and demerits of each model, as followed, after we particularly investigating the process of software fault leading to software failure, we put forward our improved scheme ? stdm and specify the process that it measure software testability more logically. at last, based on stdm we design and implement a stds ( software testability detecting system ), which can be used to measure the testability of c programs, and show the detected result in different level
本文首先介紹了軟體測試和可測試性的基本概念等用於檢測軟體可測試性的理論基礎，並詳細分析了一些理論檢測模型及各自的優缺點；接下來，針對這些可測試性檢測模型中所存在的問題，根據對軟體錯誤導致軟體失效過程的研究分析，本文提出了一種改進的解決方案stdm用於對軟體的可測試性進行量化檢測，文章在最後設計並實現了構建在此stdm模型基礎之上的一個軟體可測試性檢測工具，該工具能夠對c源程序進行可測試性檢測並得出量化結果數據，驗證了該模型的有效性。
