法向矢量 meaning in English
normal vector
Examples
- By means of the transformation from the focal coordinate system to the observation system , we obtained the external normal vector of the focal fault plane expressed in its observation system , and obtained the macrodamage degree of the researched block , which is calculated in dyadic
