简介：我们为f(T)严肃理论在宇宙论的限制的精确上探索SandageLoeb(SL)测试的影响。因为它在远类星体的系列在Lyman-森林里测量redshift飘移，SL测试是对当前的宇宙论的观察的重要补充，盖住2z的redshift沙漠5。避免数据矛盾，当模仿30的基准的模型嘲笑SL测试数据，我们基于当前的联合观察数据使用最好合适的模型。我们确定为f(T)严肃理论的参数评价上的这些SL测试数据的影响。二个典型f(T)模型被考虑，幂定律模型f(T)PL和指数形式的模型f(T)终止。结果证明SL测试罐头有效地打破存在在在另外的宇宙论的观察的今日的事密度m和小瘤常数H0之间的强壮的退化。为考虑f(T)模型，SL测试的30年的观察能极其改进m和H0的限制精确，但是不能有效地改进模型参数的限制精确。
