main tangent
解釋
主切線-
The following is main research work : 1. geometry characters ( such as tangent plane and normal plane etc. ) and differential coefficient characters are theoretically analyzed in detail, then the intersection differential coefficient system model for trace is constructed
在理論上,系統地分析了交線的幾何特徵(如切平面和法平面等)和微分特徵(如曲面的一階基本齊式等) ,建立了交線的微分系統跟蹤模型,從而為今後進一步研究求交問題提供了一個可行的途徑。
