摘要
给出一有挠Ｒ＋Ｒ２型引力理论的Ｅｉｎｓｔｅｉｎ方程和Ｃａｒｔａｎ方程．由广义位移交换下引力场作用量的不变性导出能量动量的协变守恒律，并求得了引力场的能量动量张量和超势．
The Einstein equations and Cartan equations in an Einstein-Cartan-type R+R2 theoryof gravitation are given. The covariant energy-momentum conversation laws are derived from invariance of the gravitational action undei general displacement transformation. The energy-momentumtensors and superpotential of gravitation field are obtained.
