We consider the $f(R,T)$ theory of gravity, in which the gravitational Lagrangian is given by an arbitrary function of the Ricci scalar and the trace of the energy–momentum tensor, to study static spherically symmetric wormhole geometries sustained by matter sources with isotropic pressure. According to restrictions on the wormhole geometries, we carefully adopt different strategies to construct solutions with the properties and characteristics of wormholes. Using an utterly general procedure, we provide several examples of wormholes in which the matter threading the wormhole throat satisfies all of the energy conditions and discuss general mechanisms for finding them. Finally, we postulate a smooth transformation for simplifying the nonlinear field equations and have more consistent results than the other ones to conclude that the results can be viewed as specific exact wormhole solutions without exotic matter.

我们认为 $F(\mathrm{电阻},吨)$引力理论，其中引力拉格朗日量由 Ricci 标量的任意函数和能量-动量张量的迹线给出，以研究由具有各向同性压力的物质源维持的静态球对称虫洞几何形状。根据虫洞几何结构的限制，我们谨慎地采用不同的策略来构建具有虫洞特性和特征的解决方案。使用完全通用的程序，我们提供了几个虫洞的例子，其中穿过虫洞喉咙的物质满足所有能量条件，并讨论找到它们的一般机制。最后，
