英文摘要	Given a well-constrained polynomial system f associated with a simple multiple zero x of multiplicity mu, we give a computable separation bound for isolating x from the other zeros of f. When x is only given with a limited accuracy, we give a numerical criterion for isolating a nearby cluster of mu zeros of f (counting multiplicities) in a ball around x.
