| 摘 要： | 针对乒乓球单淘汰传统抽签方法存在“局限性”、“繁琐性”和“不合理性”等无法克服的固有缺陷，进行了大胆改革，推出“逐区双分抽签法”，依据所有队均由“单或双”队员组成，单淘汰抽签也可以用“单”和“双”来处理，并对各区的轮空数分布规律、“单”和“双”的入区规律进行了理论和实践研究。采用“逐级入区”、“双分单留”、“聚单抽”等措施，依据各区的“应进数”控制入区，使得整个抽签过程做到了最大限度的随机，符合或基本符合“最佳抽签概率”。该方法是对传统抽签方法的突破，具有创新、适用意义，显得更加科学、合理和简便。 |

Practical research and principles of Single elimination series "Draw half lots on each region"——a scientific, reasonable and simple way of lot-drawing |
|
| Abstract: | Single elimination series system has been seen as limited ,complex and unreasonable. Therefore , a new change of gradual half lot2drawing in each region system has been promoted. Since the number of each team is odd or even , single elimination series system can be dealt with odd or even number. Bye number dist ribution law ,even and odd numbers law have been studied. Measures such as gradual selection , selection of odd numbers , drawing the odd numbers were taken. Numbers selected are decided by the rest riction so that the drawing can be most random. In this way ,lot2drawing is more scientific ,reasonable and simple. |
| Keywords: | single elimination series system gradual half lot-drawing in each region system optimallot-drawing ratio |
