就是以下的文啦，谢谢哪位专家辛苦下，感激不尽：
7 Procedure-reference method
7.1 Preparation
The fastening system and rail are assembled with a 5 mm thick plain reference pad of HDPE or EVA with a stiffness not less than 500MN/m measured in accordance with EN 13146-4.If the fasting assembly is designed for a thicker pad (thickness=da) shall be inserted between the rail and padwhere(da=dt-5)mm.The sleeper with strain gauges fixed as in 5.1 is placed on the support in 5.2.1.
An impact load is applied to the rail by free drop mass and recorded with the record commencing not less than 3 ms before impact and continuing for not less than 5 ms after impact.For an established test rig the magnitude and time interval of the first strain peak shall be compared with the mean of 10 preceding impacts.If it differs by more than 10% the test conditions shall be adjusted to achieve the mean condition.
For a new test rig a series of impact shall be carried out and the strain recorded ever

7.1制备
在紧固系统和铁路组装用5毫米厚的平原参考垫的高密度聚乙烯或长荣与刚度不少于500MN /米按照英文13146 - 4.If空腹集会的目的是为厚垫（厚度=达）应列入之间的铁路和padwhere （达= dt的- 5 ） mm.The轨枕与应变计固定在5.1放在支持5.2.1 。
一种冲击载荷应用到铁路的免费质量下降和记录的记录开始不得少于3毫秒之前，影响力和持续不少于5毫秒后impact.For建立试验台的规模和时间间隔的第一株应高峰相比，平均10前impacts.If它不同于10 ％以上的试验条件应加以调整，以实现平均状况。
一个新的试验台了一系列的影响，应进行和应变记录每10 impacts.When连续五年应变测量应变第一高峰规模和时间间隔内10 ％的意思是说，筹备工作已经完成。
7.2测试
随着测试垫在履行impacts.Then五年的应变纪录在随后的三个影响中所描述7.1
7.3检查卧铺条件
的完整性测试卧铺进行检查后，每次撞击测试比较的比率衡量株顶部的立场和衡量指标底部的位置与相应的比例为类似的卧铺受静载荷静载荷only.The应按照铁路座位测试10 ％以上的静态比率，测量冲击应予以拒绝和测试再次使用新的卧铺。
7.4计算
计算衰减的顶部和底部的卧铺测试台相对参考跳板的三个衡量的影响如下：
对于每个测量计算的影响
结果应报的平均价值为三个衡量影响使用的测试板。
