    Abstract: 這篇碩士論文要是研究仿射平面曲線的交點數。事實上,我們將張海潮教授和王立中教授在[CW]的論述中,歸納並得出以下我們的主要定理:
    「如果曲線F(1,y,z)在無窮遠處只有一個place,則我們可以建構出與曲線F(1,y,z)相交的曲線G_j,使得它們在所有曲線上達到最小的正交點數。」

    這是應用到Bezout定理,以及在[Moh1, Moh2, Moh3, Moh4]介紹的近似根概念。此外,我們可以將Embedding Line Theorem作為一個應用並加以證明。(請參閱第八章);In this thesis, we study the intersection number of affine plane curves.
    Actually, we generalize the argument of Chang and Wang in [CW] to obtain our main theorem as follows:

    “if the curve $F(1,y,z)$ has only one place at infinity, then we would construct a curve G_j which intersects curve F(1,y,z) attaining the positive minimal intersection number among all curves."

    This is an application of Bezout′s Theorem and the approximate roots introduced by [Moh1, Moh2, Moh3, Moh4].

    Besides, we can reprove the Embedding Line Theorem as an application (see section 8).
