By analyzing the general theory of relativity does not naturally given that the gravitational field （as substance） of the energy and momentum of these important physical quantities. Relativity system is underdetermined problem, since the system has no definite solution. It is the theory, and other forms of interaction more independent impede the unity of the four interactions. In order to overcome these difficulties, the Weyl-U（1）gauge field theory of gravity is given. In the same approximation gives consistent results and general relativity, and more concise expression , a model of the universe is gotten .there are some new ideas of space and time. These possible applications are discussed for some mysterious nature phenomena which are never explained.%通过分析认为广义相对论不能自然地给出引力场（作为物质）的能量、动量这些重要的物理量。广义相对论体系是欠定问题，在自系统无定解。它和其他相互作用的理论形式较独立，有碍四种相互作用的统一。为了克服这些困难，本文提出了引力的Weyl-U（1）规范场理论。在相同近似下给出的结果和广义相对论一致，而表达方式更简明。文中得到一个宇宙模型，对时空有一些新观点。还提出了本理论对自然界一些解释不了的神秘现象的可能应用。
