oriented sphere造句

Timerding ( 1911 ) used Laguerre's concept of oriented spheres in order to represent and derive the Lorentz transformation.
An oriented plane P in E ^ { 3 } may be interpreted as the set of all oriented spheres which are tangent to P.
As mentioned above, oriented spheres in "'R "'3 can be represented by points of four-dimensional space "'R "'4 using minimal ( isotropy ) projection, which became particularly important in Laguerre's geometry.
The transformation by reciprocal directions transforms oriented spheres into oriented spheres and oriented planes into oriented planes, leaving invariant the " tangential distance " of two cycles ( the distance between the points of each one of their common tangents ), and also conserves the lines of curvature.
