Abstract: This paper depends on literature material law, video analytic method, mathematical statistics to analyze the technical effects of the 256 offense-defense combined modes of women's volleyball at the 30th London Olympic Games, with the result indicating that under the storm, the main priority is given to "position/non-position - strong - single/double - attack effect" with the Chinese team's power still waiting to be improved. In fast break, the priority is given to "position-attack - fast - single/double - effect" by all the teams with the Chinese team waiting to improve its diversity in the attack urgently. In the second attack, what is mainly applied is the "/ non-position/position-2 - single/no - effect", with the Chinese team standing out significantly compared with its rivals. In the three-dimensional attack, "position-state- single/double - effect" is given priority to, with the Chinese team lagging behind other strong teams form America and Europe in the participation number and quality.
