With the continuous development of science and technology level in the world, experts and related staff at home and abroad began to study how to use wireless technology to transmit power. If the technology is successful, it will promote the further development of science and technology. But in the process of popularizing the technology, the electromagnetic environment that it can use is becoming more and more complex. In this paper, the needle for the effects of radio energy transmission system, transmission power and efifciency of various factors for analysis and discussion, in the hope of providing some reference data for the study of China's relevant staff in this regard.%随着全球各国科学技术水平的不断发展和提高，国内外的专家和相关工作人员开始研究开发如何利用无线技术进行电能的传输。如果这项技术研究成功，将会促进科学技术的进一步发展。但在目前该技术推广的过程中，其所能够使用的电磁环境变得越来越复杂。文章针对影响无线电能传输系统中传输功率和效率的各种因素进行分析和探讨，希望为我国相关工作人员在这方面的研究提供一些具有参考性的资料。
