radius vector meaning in Chinese
【数、物】矢径，辐；位置矢量。
Examples
- The radius vector of each solid is always a positive length .
每个立体的矢径总是正值长度。 - 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。 - 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（ 5 3 - 12 ） ，故这两个径向矢量与两个允许的d矢量平行。 - The angular extent in a specified plane which contains all the radius vectors of the polar curve of luminous intensity having lengths greater than a specified fraction of the maximum
在某一平面上，一定角宽范围内所包含的光强极轴曲线上的矢径长度均大于其最大值的某一特定比例，这种情况定义为光束的发散。 - According to the principle of odontoprisis ' force , the radius vector value of cam on the open - closed armature position was calculated by the means of one dimension searching method at the open - closed odontoprisis cam outline
该方法根据咬纸牙产生咬纸力的原因，计算实际开闭牙位置在凸轮上对应的向径值，利用计算机一维搜索方法得到开闭牙的实际位置。
