【摘要】 基于近五年500场乒乓球国际比赛数据，针对男单、女单、男双、女双及混双5个项目分别制定“四段指标评估法”的新评估标准。与沿用了三十多年的“三段指标评估法”的评估标准相比：(1)在得分率方面，男单与女单在发抢段和接抢段的优秀标准提高7.5%～12.5%；除男单发抢段的及格与不及格区间收窄2.5%外，各等级区间均呈扩大趋势，增幅2.5%～12.5%；男双、女双与混双在发抢段与接抢段的优秀标准提高5%～7.5%，良好与及格区间的上下限调整幅度存在差异，不及格区间下降2.5%～7.5%。(2)在使用率方面，男单与女单发抢段的高使用率标准降低5%，中、低使用率区间缩小5%；接抢段的高使用率标准提高2.5%，中、低使用率区间扩大2.5%～7.5%；双打发抢段和接抢段的高使用率标准降低2.5%～5.0%，中使用率区间缩小2.5%～5.0%，低使用率区间降低幅度在2.5%以内。新评估标准揭示了运动员前四拍的竞争愈发激烈，单打发抢段和双打接抢段的重要性愈发凸显，且普遍提高了发抢段与接抢段的得分率评估标准。更多还原

【Abstract】 Based on data from 500 international matches over the past five years, this study establishes new evaluation standards for the "Four-Phase Indicator Evaluation Method" across five events: men’s singles, women’s singles, men’s doubles, women’s doubles, and mixed doubles. The results indicate that, compared with the "Three-Phase Indicator Evaluation Method", which has been used for more than three decades:(1) In terms of scoring rate, the excellent-performance thresholds for both men’s and women’s singles in the serve-and-attack phase and the receive-andattack phase raised by 7.5%-12.5%. Except for a 2.5% narrowing of the pass-fail interval in the men’s singles serve-and-attack phase, the intervals for all other performance levels showed an expansion trend, with raises ranging from 2.5%-12.5%. For men’s doubles, women’s doubles, and mixed doubles, the excellent-performance thresholds in both the serve-and-attack and receive-andattack phases raised by 5%-7.5%. The upper and lower bounds of the good and pass categories were adjusted to varying degrees, while the fail category consistently narrowed by 2.5%-7.5%.(2) In terms of usage rate, the high-usage threshold in the serve-and-attack phase of men’s and women’s singles dropped by 5%, with the medium-and low-usage intervals correspondingly narrowing by 5%. In the receive-and-attack phase, the high-usage threshold raised by 2.5%, while the medium-and low-usage intervals expanded by 2.5%-7.5%. In doubles events, the high-usage thresholds in both the serve-and-attack and receive-and-attack phases dropped by 2.5%-5.0%, the medium-usage interval narrowed by 2.5%-5.0%, and the low-usage interval dropped by 0%-2.5%.The new evaluation standards reveal increasingly intense competition in the first four strokes of rallies. The importance of the serve-and-attack phase in singles and the receive-andattack phase in doubles has become more pronounced. Overall, the new standards raise the scoringrate benchmarks for both the serve-and-attack and receive-and-attack phases.更多还原
