摘要：

We discuss two different ways to construct new invariants of Legendrian knots in the standard contact R-3. These invariants are defined combinatorially, in terms of certain planar projections, and (sometimes) allow us to distinguish Legendrian knots which are not Legendrian isotopic but have the same classical invariants.
