| 摘 要： | 根据地洼学说关于地壳演化的新理论,将地球置于银河系各级引力场研究,发现银河年与地球绕日运行周期(年)有许多相似之处,后者控制了地球上短期的生物兴衰和四季交替,前者是引起地球上长期冷热变化,导致全球的生物质变进化、冰川活动及海侵海退等循银河年周期发生的根本原因。银河年是建立理想地质年代表的基础,每一个银河年就是一个代。依目前天文观测及全球生物质变进化和冰期资料来看,银河年时距以260 Ma为宜。本文据此提出了一个新的地质年代表。

| Abstract: | Based on the new understanding about the Crust evolution from diwa theory, placing the Earth in the galactic gravity field of different levels, it is found that there are many similarities between a galactic year and a period (year) on which the Earth revolve round the Sun. The latter controls the short term rise and decline of living things and alternation of the four seasons on the Earth; while the former is the basic reason why there were long term cold and heat changes on the Earth, which lead to the emergence of qualitative change evolution of organisms, glaciation and transgression-regression on global scale following galactic year. Hence it is considered that a galactic year can be based on to institute an ideal geologic time scale in which a galactic year is an era. According to the recent astronomic observations, qualitative change evolution of organisms and global glacial stage data, the appropriate time interval of a galactic year should be 260 Ma, based on which a new geologic time scale is put forward in this paper. |
