In recent years, for the high voltage transmission lines suffered serious Icing lead wire dancing, break and tower collapsed, domestic and foreign strengthened the study of high-voltage overhead line deicing methods and put forward a variety of line deicing methods. This paper first introduced thermal ice-melting method, mechanical deicing method, natural deicing method and several common deicing methods and analyzed the pros and cons of various deicing program. Based on the analysis of deicing methods for the high voltage transmission lines, a new and simple high voltage transmission line deicer is brought forward. This paper briefly discussed the basic principles and advantages of the device, providing a new way of thinking for the high voltage transmission lines deicing and having a certain value and social benefits.

This article presents some streamlined and intentionally oversimplified ideas about educating future communication disorders professionals to use some of the most basic principles of evidence-based practice. Working from a popular five-step approach, modifications are suggested that may make the ideas more accessible, and therefore more useful, for university faculty, other supervisors, and future professionals in speech-language pathology, audiology, and related fields.
