摘要
乒乓球硬度检测方法已经执行49年,其方法效率低下,不适应现代乒乓球生产线的要求。针对此缺点,提出两种检测乒乓球硬度的新方法,并用实验验证新方法的可行性,通过统计软件分析最终确定新方法具有合理性,最后探讨了对GB/T 20045-2005中关于乒乓球硬度检测方法的修改建议。
The hardness testing method of table tennis has been carried out for 49 years. The method is inefficient and can not meet the efficiency of production line. For this shortcoming, two new methods about hardness testing are discussed. Besides, the feasibility of the new method is proved by large numbers of experiments, and the rationality is studied through the statistical analysis software. Last, the revision for hardness testing in GB/T 20045-2005 is presented.
