Almost defference sets have strong relationship with binary sequences with optimal 3-level autocorrelation, which are of significant applied bachground. We constructed 2 new infinite families of almost difference sets by using cyclotomy; Perfect binary sequences and perfect binary sequences pairs are of significant theoretical value and applied background, they correspond to cycle Hadamard matrices and difference sets pairs respectively.

几乎差集与具有最优3级自相关二元序列密切相关，具有强烈的应用背景，我们借助分圆方法构造了几乎差集的两个新的无穷类；最佳二进序列和最佳二进序列偶有着重要的理论价值和应用背景，它们分别对应着循环Hadamard矩阵和差集偶。

With differential geometry knowledge, the local characters of the blade surface are analyzed. Based on researching the cylindrical cutters osculating location, the methods to calculate the osculating location of the conic cutter and the torus cutter are discussed. A method of tool path planning based on the second order osculating method is preferred.

利用微分几何学知识，分析了螺旋桨桨叶曲面的局部特征，在研究圆柱刀二阶密切法规划刀位的基础上，探讨了圆锥刀和圆环刀的二阶密切刀位计算方法，采用二阶密切法规划刀位可以显著地提高加工精度。
