Abstract:	人類生活裡有許多仰賴太空任務及衛星所提供的服務，因而伴隨太空活動產生了許多太空碎片，使得因為這些碎片撞擊，導致嚴重危害的機率快速地提高。因而研究其碰撞的可能性，成為一項刻不容緩的工作。鑑於此，太空中的撞擊預測相對重要。此次採用二列元素(Two-Line Elements)換算，取得所需的運算參數。本文藉由的空間密度方法，找出每一個飛行物體在空間中所佔有的空間密度值。因飛行物體的行為如同電子在導體中流動的情形。有此概念，當然有通量概念產生，進而推導出碰撞次數。有了空間密度與碰撞次數的概念，因此便能著手於碰撞的繁雜計算，更能近一步瞭解碰撞機率。 Human life is dependent on many space missions and satellite services provided, with space activities which have a lot of space debris, which makes debris impact, cause serious harm to the rapid rate of increase. Therefore study the collision probability, as a matter of great urgency. As such, the impact of space predicted relative importance. This use of Two-Line Elements conversion, obtain the required computational parameters. In this study the spatial density method to identify each one flying objects in space share some space density. By flying objects act as a conductor in electronic flow situation. This concept is, of course, the concept of flux, and thus the number of collisions is derived. With spatial density and collision frequency of the concept, it can proceed in the complicated collision, taking a step forward in better understanding the collision probability.
