This thesis discusses the following. First, we use the condition of inference and the concept of wildhabor cone to design the addendum circle. Second, we use TCA technique to obtain the relationship between the slip track and the angle of action, which then leads to the calculation of contact ratios. We can then design the tooth face width and the numbers of teeth based on contact ratios.

本文一开始先对空间渐开线齿轮之齿冠圆范围使用齿轮干涉条件与Phillips提出的Wildhabor Cone进行设定，再利用Litvin提出的齿面接触分析方法，得到空间渐开线齿轮对在啮合过程中作用角与滑动轨迹之间的关系，藉由此关系可以建立一套设计流程来调整齿面宽以及齿数等参数，使其能符合设计需求。

In this paper, the adjointness of the product of two differential operators generated by a third order normal and singular symmetric differential expression in the limit-circle case is discussed. The necessary and sufficient conditions which make the product operators being the adjoint operators obtained by the matrix analysis and calculation.

本文首先讨论了正则和奇异两种情况下两个极限圆型三阶对称微分算式生成的微分算子的乘积的自共轭性，运用矩阵分析和计算，得到了乘积算子为自共轭算子时边界应满足的充分必要条件，同时得到了幂算子的自共轭性、自共轭算子乘积的自共轭性等乘积算子的其它若干性质。

Treating with coils as aeolotropy, this paper brings forward a set of mathematical mode for computing internal stress distribution of coil in the process of coil coiling, in which some factors are taken into account, such as the transverse distribution of shape, crown and curl tension of the strip, the friction between the strip and the reel, the friction between strips, and etc. Because the reel shrinkage and the inner circle of the strip losing radial restrain and circumferential restrain can induce interlayer slipping and the change of the whole coil compactedness , the assumption concerned ——"virtual reel" in the process of coil uncoiling is put forward, which takes the form of slow action to express the uncoiling process and, therefore clearly simulates the variation course of internal stress distribution of coil in the process of coil uncoiling.

考虑到带材板凸度、卷取张力的横向分布以及带材与卷筒之间、带材与带材之间的摩擦力等因素的影响，并将钢卷按各向异性体处理，提出一套计算卷取过程中钢卷内部应力分布的数学模型；同时考虑到卸卷过程中由于卷筒的收缩，钢卷内圈失去径向和周向约束而引起层间滑移及整个钢卷紧密程度发生变化，提出钢卷卸卷过程中有关"虚拟卷筒"假设，将卸卷过程以"慢动作"的形式表示出来，清楚地模拟出卸卷过程中钢卷内部应力分布的变化历程。
