图4. 卫星重力与地球重力场的引文聚类的时间线视图
不同聚类所代表的课题具有不同的爆发强度与延续时长。时间线视图上的年轮大小代表课题的爆发强度；右侧文字为聚类标签；水平线长度代表该聚类的持续时间；顶部数字为各时间切片的末尾年份
Fig.4. Timeline view of citation clustering between satellite gravity and the Earth's gravity field
The topics represented by different clusters have different burst intensity and duration. The size of the annual ring on the timeline view represents the intensity of the topic； The text on the right is the cluster label； The length of the horizontal line represents the duration of the cluster； The top number is the end year of each time slice
