论文摘要
Harko and Moraes声称，在$ f（r，t）$重力中，带有$ f（r，t）= f_1（r）+f_2（t）$，一词$ f_2（t）$不能纳入lagrangian $ {\ cal l} _m $。仔细检查他们的评论发现他们做出了几个可疑的假设，而没有指出我们工作中的任何错误。最值得注意的是，他们不合理地声称，两个术语$ {\ cal l} _m $和$ f_2（t）$是``不同的来源''，而他们的推断只有第一个为能量动量张紧剂贡献的是任意的。同样重要的是，它们从拉格朗日公式中推导运动方程，施加了保护约束{\ it hoc}，而不是通过拉格朗日乘数导致结论不一致。
Harko and Moraes claim that in $f(R,T)$ gravity with $f(R,T)=f_1(R)+f_2(T)$, the term $f_2(T)$ cannot be incorporated in the matter Lagrangian ${\cal L}_m$. A careful examination of their Comment finds that they have made several dubious assumptions without indicating any errors in our work. Most notably, they have unjustifiably claimed that the two terms ${\cal L}_m$ and $f_2(T)$ are of ``different origin,'' and their inference that only the first contributes to the energy momentum tensor is arbitrary. Also significant, their derivation of equations of motion from a Lagrangian formulation, imposing conservation constraints {\it ad hoc} rather than via Lagrange multipliers, leads to inconsistent conclusions.
