根据空间、时间和物质运动的不可分离性,给出了物质“存在”的数学模型。探讨了在时间进程中时态演化的规律。引入异位点集合和同位点集后,推导了地物动态变化的数学模型。地球科学中事物演化的普遍性由大陆漂移的极慢变化、地物和地貌的常态变化和气侯的快速变化体现。
"Matter existence" model was established in this paper based on the inseparability of the three elements; namely, space, time and movement. Further, the law of tense evolution in time was explored as well; and then the mathematical model of dynamic change of geo-object was deduced through the introduction of different and same place point set. The evolution universality in geosciences is represented by the continental drift with extremely slow speed; and the rapid and constant change of surface and landform.
