Table tennis diameter changes to audience influence research based on mechanics and least square method

Zhaopeng Ji


The paper adopts qualitative and quantitative combinative method researching table tennis diameter changes caused influences. At first, it makes physical analysis and mechanical analysis of athletes experience quality, it gets the conclusion that table tennis diameter enlarge causes flight speed slow down, rotation weakens and rebound angle increase. Then, by analyzing audience applauses times and time relations, the paper establishes linear least square method model. On the premise that meet residue squares sum be minimum, apply MATLAB software; it gets audience appreciation quality and table tennis diameters size mathematical relational graph.
