1·Many scientists provided valuable research and input into the creation of the geologic time scale.

许多科学家为地质时间尺度的建立提供了有价值的研究和投入。

2·As he explains, the Geologic Time Scale is largely based on the stratigraphic record.

他解释说，地质时间尺度很大程度上基于对地层的记录。

3·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.

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。

4·On a geologic time scale, the recent, human-induced planetary warming has been quite sudden, and the huge ice sheets have only just started to respond.

从地质时间的尺度来看，近来人类活动引起的地球变暖现象是相当突然的，巨大的冰盖这才刚刚开始有所反应。

5·Using the codes 1 to 6 representing the different time periods in the evolutionary time scale shown in Figure 1, indicate the geologic time period that best corresponds to each description.

用地质年代表(表1)中的不同年代的编号1 - 6，来代表每个描述所出现的地质年代。

6·Engineering practices show that lining hanging concrete in time is an important technique to make sure of the construction safety of large-scale surge tank project at complex geologic condition.

工程实践表明，跟进衬砌悬挂混凝土是保证复杂地质条件下大型竖井工程施工安全的重要技术措施。

7·It is also possible to read about the history of the geological time scale, and find out more about how it is organised, or go to a specific time period using the UCMP geologic time Machine.

从这里可以了解地质时标的历史，地质时标的组成，也可以利用加州大学古生物博物馆的“时间机器”进入特定的地质时期。

8·The geologic significance at a time can be explained by time-scale slice up according to 3D geologic model.

对三维地质模型进行时间轴切片，就对某一时刻的地质意义做出解释。
