With the continuous development of society, science and technology, mechanical engineering industry in our country is making progress, in which similarity theory has played a great role. It plays a guide and reference role in mechanical engineering technology innovation and greatly promotes the development of mechanical engineering. At present, the application scope of the similarity theory is more and more wide, and the importance of similarity theory should be realized in mechanical engineering industry , and the specific core content of this theory should be understood and grasped. Scientific application of similarity theory should be given full play to utility with the understanding of actual development and the demand of the mechanical engineering to promote the long-term development of mechanical engineering industry.
