		     | 本文研究了外三角范畴中相对合冲对象和粘合R (A',A,A'')中相对合冲对象的保持问题.利用相对同调的方法,获得了相对合冲对象的一些性质和它的等价刻画,推广了阿贝尔范畴和三角范畴中一些结果,给出了相对投射维数的一个等价刻画.主要证明了:在满足一定条件时,A'和A''中的相对合冲对象可以诱导出A中的相对合冲对象.反之,对于A中的相对合冲对象也可以诱导出A'和A''中的相对合冲对象. |

                | In this paper, we study the Gorenstein syzygy objects and Recollements of the Extriangulated categories. Using the relative homological methods, we get its some properties and a characterization, and a characterization of Gorenstein projective dimesions. For a recollement R(A', A, A'') of extriangulated categories, we mainly show that Gorenstein syzygy objects in A' and A'' induce Gorenstein syzygy objects in A under certain conditions, and prove that Gorenstein syzygy objects in A induce Gorenstein syzygy objects in A' and A'' under certain conditions. |
