Simply change the radius to 2000, and you should start to see some results, assuming, of course, that you put some data in the database on the same continent as your location.
只需将半径更改为2000，您应当便会看到一些结果，当然，要假定您在数据库中相同的地区放置了一些数据作为您的位置。
In Listing 5, the changes start right at the top of the page where you add a change listener to the radius control.
在清单5中，更改刚好起始于页面的顶部，这里为半径控制添加一个更改侦听器。
For a lot of times in turns you have varying amounts of traction throughout the radius of the turn. What kind of little adjustments will me make, when we start maybe lose traction to get back.
因过弯半径的不同，抓地力也会有变，而我会做什么样的调整以重新获得抓地力？
