论文摘要
我们研究由双曲线奇异性附近的Riemann表面引导的局部正谐波电流，分离量没有质量。 Nguyên定理说，这种奇异点的lelong数量消失了。我们证明了这一特性很清晰：对于奇异性附近的这一电流，一个人无法获得更好的质量估计。
We study local positive harmonic currents directed by a foliation by Riemann surfaces near a hyperbolic singularity which have no mass on the separatrices. A theorem of Nguyên says that the Lelong number of such a current at the singular point vanishes. We prove that this property is sharp: one cannot have any better mass estimate for this current near the singularity.
