讨论了有关复合规范玻色子动力学生成的各种理论问题。特别地，我们阐明了隐藏局域对称的无质量规范玻色子动态产生的一般机制。并阐明了与Weinberg-Witten型不走定理的一致性。我们强调这种无质量或有质量规范玻色子的动力学世代是相当普遍的现象，可以很容易地发生在各种不受cpn - 1模型和二维系统的限制的系统中。作为一个特殊的例子，我们一般地证明了在任何一般坐标不变系统中，只要背景度规是平闵可夫斯基的，就必须动态地产生无质量引力子。
Various theoretical problems concerning dynamical generation of composite gauge bosons are discussed. In particular we clarify the general mechanism how massless gauge bosons of hidden local symmetry is created dynamically. Consistency with Weinberg-Witten type no-go theorem is also clarified. We emphasize that such dynamical generations of gauge bosons, massless or massive, are rather common phenomena which can occur easily in a wide variety of systems not restricted in cpN-l model nor in 2 dimensions. As a special example we prove generally that massless graviton must be generated dynamically in any general coordinate invariant systems as far as the background metric is flat Minkowskian.
