本文通过构造无界复形的分解，定义并研究GF-闭环上无界复形的Gorenstein平坦维数和Gorenstein余扭维数.研究了环变换下维数的性质。
In this article, we define and study the Gorenstein flat dimension and Gorenstein cotorsion dimension for unbounded complexes over GF-closed rings by constructions of resolutions of unbounded complexes. The behavior of the dimensions under change of rings is investigated.
