采用光子与电子（正电子）的最小电磁耦合模型，获得了光子链图传播子重整化的有限量。
In the minimum electromagnetismcoupling model of interaction between photonand electron(antielectron), we obtain the renormalization finite quantity of photon chain propagator.
这项特色是很受人欢迎的，因为它精确地吻合所有已知基本作用力载体（如传播电磁力的光子以及重力的重力子）的性质。
This feature is very welcome because it precisely matches the properties of the carriers of all known fundamental forces, such as the photon (for electromagnetism) and the graviton (for gravity).
