论文摘要
我们描述了一个维度估值环$ V $的直接扩展，该$ V $可以将其嵌入到某个超级滤波器相对于$ V $的超级分离中。对于这样的扩展，有一种Artin的近似值。
We describe the immediate extensions of a one dimensional valuation ring $V$ which could be embedded in some separation of a ultrapower of $V$ with respect to a certain ultrafilter. For such extensions holds a kind of Artin's approximation.
