When the secondary wave is just starting at e, that from c will have formed a hemisphere of radius cg . 当E处的次波刚开始发出时，从C发出的次波已形成一个半径为CG的半球面。
On the other hand, it seems unlikely that this process can produce objects much in excess of a few kilometers in radius . 但是，这个过程看来不可能形成半径超过几公里的天体。
A molecule whose stokes' radius approaches or exceeds the pore radius does not enter the gel and is said to be excluded . 一个分子，它的Stokes半经接近或超过网眼半经，不进入凝胶内，称为被排阻。
Bohr radius was the radius of the circle in which the electron moved in the ground state of the hydrogen atom, according to the bohr theory . 根据玻尔理论，玻尔半径是在基态氢原子中电子运动的圆周半径。
A burnedout star could collapse to so small a radius as to make the effects of general relativity quite important near its surface . 一个燃烧完的星球可能坍缩到如此之小的半径，以致在其表面附近，广义相对论效应相当重要。
Second, since the radius vectors r to the extreme points of the ellipse satisfy(5. 3-12)they are parallel to the two allowed d vectors . 其次，因为到椭圆极值点的径向矢量r满足式（53-12），故这两个径向矢量与两个允许的D矢量平行。
