- While China’s heatmap has the typical upper left orientation hot spot, it doesn’t have the vertical scan down that creates the “leg” of the F. 谷歌中国的热图非常典型，热点都源自左上方。但是它并没有垂直延伸从而形成F型搜索模型的F字母的尾巴。
- VSF? Vertical Scanning Frequency? 垂直扫描频率，场频?
- In scanning, the technique of using more than one vertical scan to reproduce a complete image. In television, 2:1 interlace is used, giving two vertical scans(fields) per frame; one field scans odd lines, and one field scans the even lines of the frame. 利用多次垂直扫描来重显一幅完整图象的扫描技术。电视中使用2：1的交错率，即每帧分两场，垂直扫描两次，一场扫描奇数行，另一场扫描偶数行。
- Now, it is proved here by studying the mean scan period of netted radar systems.This is especially important for studying the ECCM capability and evaluation rule of netted radar systems. 通过对雷达网系统平均扫描周期的研究，从理论上证明了雷达网系统具有航迹快速起始的性能，这对于研究雷达网系统的反电子对抗性能和评估准则具有特别重要的意义。
- oscillations in the vertical scan 垂直扫描振荡
