摘要
大家知道，第二型曲面积分与曲面的侧向有关．而一般的教科书对由直角坐标给出的方程的第二型曲面积分有较详细的论述，对由参数方程给出的曲面，给出第二型曲面积分公式时，只笼统地给予说明．本文给出由参数方程确定的曲面方程。
In this paper, we treat the problem on determining sides of Surface integral of the second kind from parametric equation, and obtain the computation formulae of the surface integral of the second kind with the clear and definite relation between sides and positive/negetive sign.
