摘要：

We show that the residual curve R and the Darboux curve R' associated to a virtual 4-bar mechanism are two smooth elliptic curves defined over R, isomorphic over C but not isomorphic over R, see Theorem 2. The same question seems to be open for elliptic curves coming from an actual 4-bar mechanism. In this case we show that the corresponding real curves R(R) and R' (R) are diffeomorphic, see Theorem 3.
