This article discusses overall and systematically the problem of perpen-dicularity of two planes in four dimensional space.Based on recent malerials,an approach is made to the related theory andpractice of drawing.The theorems and definitions of the absolute perpendicu-larity of two planes are proved analytically,and the conclusion is that theorthographic projection of two adsolutely perpendicular planes on the sameplanoid is also in perpendicular.Further,the problem of drawing an absoluteperpendicular plane through a given point to a given plane and finding thefoot of the perpendicular is solved.As to the common perpendicular plane of the two planes,some discussionis made in detail.It is very interesting:There is a common that is the intr-insic plane between two partially parallel planes.At it's two sides,the twoplanes are in indefinie distance.theother common perpenpicular plane is thenonintrinsic plane.

本文全面系统地论述了四维空间中两平面的垂直问题。在现有参考资料的基础上,对理论和作图方法都作了某些进一步的探讨,用解析法论证了两平面成绝对垂直的有关定理和定义,并且得出两绝对垂直的平面,它们在同一超平面上的投影也互相垂直。本文还解决了过已知点向已知平面作绝对垂直平面并求垂足的具体作图问题。关于两平面的公垂平面,也作了详细的说明和论证。特别有趣的是:两部分平行的平面有一个固有的公垂平面,它是两平面上一对距离最短的平行线所决定的平面,在这个公垂面的两侧,两平面无限远离。另一个公垂面是非固有平面。

In the light of the addition of two screws, the distribution of instantaneous axes along the common perpendicular of the two screws is determined and all possible sorts of axodes are derived kinematically with the pitch of the relative motion screw in the gear pair as the basis and the transmission ratio i as an independent variable.

本文利用螺旋迭加的结果,以齿轮副相对运动螺旋的节距为基础,以传动比i为自变参数,确定了瞬时轴分布范围,并导出了可能存在的各类瞬轴面。

This paper defined a sort of conditional parameter perpendicular system, which was a generalization of common perpendicular system. The theory of Z orthogonality was put forward with the background of center or focus in qualitative theory of ordinary differential equation. With gradually improving, this theory is expected to help the solution of upper bound of foci's value to be worked out in focus system.

文章定义了一类条件参变量正交系统,它是普通正交理论的一种推广。Z正交理论是以常微分方程定性理论中的中心─焦点问题为背景提出的,期望随着这一理论的进一步完善,能够推动解决中心─焦点系统的焦点量上界问题。
