利用在拉氏量中引力场的二次型内核以及引力场传播子的对称性

构造出一些基本的对称性模块

它们构成了满足该组对称性的完备空间。推导求得了这些模块两两之间的乘积关系，并由此简便地推导得到了有质量的KaluzaKlein引力场与零质量的引力场的传播子。

According to the symmetry of the kernal of the quadratic term in the graviton Lagrangian and the symmetry of the graviton propagator

a complete basis set of building blocks satisfying this symmetry and obtain their product relations is constructed. Using these building blocks

the propagator expressions of the massive KaluzaKlein graviton and the massless graviton is easily derived

respectively.
