对画较大半径的园弧有一定的实用价值。

Thus, this mechanism offers a supplement for the drawing arc. especially, it is of practical value to longer radiuses.

否则，取更大半径的空间球，重复上述过程。

Otherwise, the sphere with larger radius is taken, and above searching process is repeated.

通过地形改正数学物理模型的建立，提出了地形改正最大半径的选择方法。

As physics-mathematics model of topographic amendment is created, it have been put forward to selectmethod of largest radius about topographic amendment.

r+ And let's say that sodium has a radius, r plus, r- and chlorine has a radius, r minus, when r is very large in comparison to the radii of the ions, I don't need to draw them this way.

让我们假设钠有半径，是，氯也有半径，是，当r比离子半径大很多的时候，我不需要这样来描述。
