中国于2008年成功举办了北京奥运会，并以51枚金牌的优异成绩在奥运会上占据榜首，这表明中国已经成为一个体育大国，如果想要成为体育强国，技能主导类三大球集体竞技运动是关键。中国足球运动的发展不景气；中国篮球项目也任重道远；中国女排在20年后的雅典奥运会享有重获冠军时牵动国人心弦的顽强和霸气，虽然现已经沦为二流球队，但仍然是中国三大球运动中获奖牌希望最大的运动。　　　2012年伦敦奥运会中中国女排依次负于美国队、巴西队、日本队，虽然战胜韩国队，但因积分差距位居第五，因此对2012年伦敦奥运会中国女排与世界前四强进行技战术对比分析，为中国队与其他强队的发展提供理论，使其认清优势与不足，在原有基础上扬长避短。因研究对象仅为中国队、美国队、巴西队、日本队、韩国队，所以本文在表述中将世界女排前四强用外国女排代替。笔者对一攻和防反每个技战术环节先从整体进行对比分析，再剖析；先从纵向进行分析，后横向分析，直至将数据对比分析清晰，并得出结论。本文运用了文献资料法，录像分析法、数理统计法、逻辑分析法和访谈法。　　　研究结果表明：发球：中国女排比国外女排稳定，但缺乏攻击性，外国女排的破攻率远远高于中国；一攻技战术体系：接发球技术：中外到位率接近，但中国无攻过网率高于外国，给对方组织进攻的机会；二传传球技术：与外国持平；二传传球个人战术扣死率高于外国女排，队长魏秋月传球稳定且到位率高，能较好地把握时机，随机应变，起到主导作用；扣球技术：外国女排的强攻扣死率高于中国，但快攻远远低于中国；战术上中国多拘泥于四号位的强攻，可以多组织其他位置的强攻，干扰对方拦网。同时，快攻中因为路线单一，中国队的背飞战术被拦回率拦死率非常高；防反技战术体系中分别对一、二、三次防反（占总防反的96%）进行技战术统计对比分析，结果表明外国队在防守方面高于中国，中国需在保持稳定进攻的同时加强拦网及防守。

In 2008 China hosted the Beijing Olympic Games successfully, and obtained the 51 gold medals in the Olympic Games with its excellent result, so it showed that China has become a sports power, if you want to become a sports power, collective ball sports is top priority. The Chinese football development have depressed for a long time, and the strength of the Chinese basketball project has also dropped substantially.Chinese woman's volleyball team are the pride of the Chinese people have that has "won" honor and regain people heartstrings after 20 years of the Athens Olympic champion affects , tenacity and domineering, although it now has become a second-rate team, it is still one of the biggest sport among three balls to won a medal hope .Chinese woman's volleyball team in the 2012 London Olympic Games fall behind United States, Brazil,Japan and South Korea and ranked fifth in the gap,so it is essential to make a comparative analysis and find gaps between the Chinese woman's volleyball team and the world's first four ranks.The author make a whole analyze on each tactics and transverse after from longitudinal analysis,finally,making a conclusion.This paper uses the literature material law, video analysis, mathematical statistics, logic analysis and interview method.The research results show that the serve: Chinese woman's volleyball team is more stable than foreign woman's volleyball team , but lacking of aggression, the foreign team's attack rate is much higher than China; the tactics system: receiving technology: it is much closer for home and abroad, but Chinese net rate without tapping is much higher than that of foreign countries, and give opportunity to others;passing technology: making a balance with foreign, and the death rates of individual tactical are higher than foreign teams,and the captain of China Wei Qiuyue grasped the opportunity, random strain, and play a leading role in the match.Spiking technique:China storm buckle death rate is lower than the foreign countries, but the fast break is much higher than foreign; China is more constrained by a storm, 4 and it is possible to organize many other form in tactics.block rate of fly was backed higher in fast break,because of the same single road, we make a comparative analysis among one, two and three times the counter-attack (96%) of total defence,so it can be shown that foreign teams in defense is higher than China,and China needs to keep stable ,at the same time strengthen the blocking and defensive attack.
