摘要：

Let Omega be a bounded domain in R-n with C-1 boundary and let u(lambda) be a Dirichlet Laplace eigenfunction in Omega with eigenvalue lambda. We show that the (n - 1)-dimensional Hausdorff measure of the zero set of u(lambda) does not exceed C(Omega)root lambda. This result is new even for the case of domains with C-infinity-smooth boundary.
