摘要：

Let F be an algebraic surface in the projective 3-space and G(0) a surface touching F along the curve C-0 = F boolean AND G(0). We develop a special algorithm to find all algebraic surfaces touching F along any algebraic curve C linked to C-0. Then, after observing that on an algebraic non-singular cone F of degree less than or equal to 4 any curve C is linked to a group of generators, we determine all algebraic surfaces circumscribed about a cone of degree 3 or 4.
