为了使研究更加贴近于工程,便于解析处理,提出准面的概念,并确立由准面到准线的研究路线,给出了各种传动形式下准面与准线的具体特征,证明了共轭准面上两准线的诱导测地曲率等于零的这一不干涉条件,进而指出,当准面为平行轴和相交轴传动的节曲面时,不干涉条件自然满足。 - Based on the geometry characteristics of bertrand surfaces , the complicated surface conjugation issue can be discussed with their directrix line . according to the different generatrix line which can be divided into common plane curve , circular - arc curve and straight line , bertrand conjugation surfaces are parted into three typical types , and the basic equation and differential formula are established , then the conjugation conditions are found . aiming at the inclusive problem , the structure condition is given
论文将白川德共轭按母线为一般平面曲线、圆弧、直线分为三种典型类型,分别建立了共轭的基本方程与微分关系式,据此给出了各种类型的共轭基本条件,发现这是一类更强更严的条件,存在有相容问题,进而研究了白川德共轭的结构条件,至此确立了白川德共轭的基本框架。
