摘要：

在以前的工作[1]中，已经提出了三种TAIJI轨道部署来组成替代的LISA-TAIJI网络，TAIJim（通过$20^\circ$和相对于黄道平面倾斜的$-60^\circ$引导地球），TAIJip（通过$20^\circ$引导地球和倾斜的$+60^\circ$），相对于LISA任务（通过$20^\circ$和倾斜的$+60^\circ$跟踪地球）的TAIJic（与LISA共定位和共面）。LISA-TAIJIM网络被认为是最有能力观测大质量黑洞双星的结构。在这项工作中，我们研究了三个网络的性能随机引力波背景（SGWB），特别是两个合格的配置，LISA-TAIJIm和LISA-TAIJIp的比较。这项调查表明，检测能力的LISA-TAIJIm与LISA-TAIJIp网络的一些特定的SGWB光谱形状是有竞争力的。LISA-TAIJim通过确定信号的参数来分离SGWB分量的能力也与LISA-TAIJip相同。综合考虑SGWB和大质量黑洞双星观测的性能，TAIJIM可以被认为是实现与LISA联合观测的最佳选择。

英文摘要：

In previous work [1], three TAIJI orbital deployments have been proposed to compose alternative LISA-TAIJI networks, TAIJIm (leading the Earth by $20^\circ$ and $-60^\circ$ inclined with respect to ecliptic plane), TAIJIp (leading the Earth by $20^\circ$ and $+60^\circ$ inclined), TAIJIc (colocated and coplanar with LISA) with respect to the LISA mission (trailing the Earth by $20^\circ$ and $+60^\circ$ inclined). And the LISA-TAIJIm network has been identified as the most capable configuration for massive black hole binary observation. In this work, we examine the performance of three networks to the stochastic gravitational wave background (SGWB) especially for the comparison of two eligible configurations, LISA-TAIJIm and LISA-TAIJIp. This investigation shows that the detectability of LISA-TAIJIm is competitive with the LISA-TAIJIp network for some specific SGWB spectral shapes. And the capability of LISA-TAIJIm is also identical to LISA-TAIJIp to separate the SGWB components by determining the parameters of signals. Considering the performances on SGWB and massive black hole binaries observations, the TAIJIm could be recognized as an optimal option to fulfill joint observations with LISA.
