For instance, in a device with two gears, if one gear is twice the size of the other, the ratio would be 2:1.
例如，两个齿轮的传动机构中，如果一齿轮的尺寸是另一齿轮的两倍，那么传动比就是2：1。

Line recovery (the amount of line recovered with each turn of the handle) is related to gearratio, but it's also affected by the size of the reel's spool.
