【摘要】 为了探求龙骨参数对体育馆用木质地板功能指标的影响情况,于2006年6月至12月在中体建科国际运动地面科学检测中心以龙骨的宽度、厚度和间距为因素进行了一次回归正交试验。通过对试验进行方差分析,得出回归方程。试验结果表明,间距是影响冲击吸收率和球反弹率最主要的因素;宽度和厚度之间普遍存在交互作用,并且该交互作用对冲击吸收率、标准垂直变形和球反弹率的影响都很显著。更多还原

【Abstract】 In order to find out the influence of load distribution strips’ parameters on the function values of wooden flooring for gymnasium,an orthogonal experiment about the width,thickness and span of load distribution strips was held in China International Sporsfloor Constructs Science Test Center (CIST) from June,2006 to December,2006. According to the variance analysis to the experiment,two regression equations were got.The result indicated that span is the dominant factor when load distribution strips influence the force reduction and the ball rebound.Meanwhile,there is a cross correlation whose influence is great to all of the three function values between width and thickness.更多还原
