However, there are two possible axial directions . 不过,沿着轴线也还有两种可能的方向。
The same machine was used by pomeroy(1970)to explore the effect of skew . Pomeroy(1970)利用同样装置对轴线交错的影响进行了探索。
We have found a solution which does not cross the axis and one which crossed the axis once . 我们已经求得了一个不通过轴线的解以及一个只通过轴线一次的解。
This turnable can be rotated in its own plane about its axis a. and is mounted on gimbals within a ring . 此内转台可在其自身平面内绕其轴线A转动,并装在一个位于圆环里面的常平架上。
Thus the path of the vehicle mass center must be a circle around the axis, i. e. it must be a minor circle of the earth, lying on a parallel of latitude . 所以飞行器质心的轨迹必须是围绕轴线的一个圆,即它必须是一个平行于纬度线的地球的小圆。
it is usually convenient to replace δs by its components δs1 and δs2 parallel to any two perpendicular axes ox, oy in the plane. 通常用它的分量s1和s2来代替s较为方便,它们分别沿平面内的ox,oy两个正交的轴线的方向。
