摘要翻译：
我们给出了具有孤立奇点的复代数曲面的例子，使得这些奇点不是度量圆锥的，即奇点附近曲面的芽相对于内度量不是锥的双Lipschitz等价的。证明度量二次曲线结构不存在的技术与度量同调的发展有关。例子的类别相当大，它包括一些Brieskorn曲面。

英文摘要：
  We produce examples of complex algebraic surfaces with isolated singularities such that these singularities are not metrically conic, i.e. the germs of the surfaces near singular points are not bi-Lipschitz equivalent, with respect to the inner metric, to cones. The technique used to prove the nonexistence of the metric conic structure is related to a development of Metric Homology. The class of the examples is rather large and it includes some surfaces of Brieskorn.
