The signature hole is the 8th 162 yards , par 3 where you play across gosford bay after which the hole is named to a far from generous green , close to a barrier of sleepers that provide protection from the tide 第8洞为签名洞162码，标准杆数3 。击球越过高斯福德海湾，到达一个非常狭小的果岭，紧临一道枕木屏障用来防护潮汐的侵入。
When the train moves , the wheel and the track system will interact each other . because of the action of the wheel , the track may bright bent transformation , and the transformation spread in the ground 轨道系统由铁轨、枕木和碎石垫层组成，列车在运行时车轮与轨道系统会产生相互作用，由于轮重的作用使轨道产生弯曲变形，这一弯曲波通过周围地层向外传播。
We consider each sleeper as an abutment of opposite forces , rails on horizontal sleepers as a mock dispersed elastic ground beam model and trains as moving load on beams . geometric roughness and damping are not taken into consideration 将每根枕木考虑成一个支座反力，将横向枕木支承的钢轨模拟成离散的弹性地基梁模型，将列车考虑成一个作用在梁上的移动荷载。
The model contains nose rail , wing rail , locking hooks and all relative components . the crossties are simplified as elastic foundations . thus , the model reveals the real working state of the locking hooks 论文中采用的计算模型包括心轨、翼轨、锁闭钩等几乎所有的相关部件，没有建模的枕木及地基也做了相应的简化处理，并引入到了边界条件中，比较真实地反映了锁闭钩的真实受力状态。
In the dynamic system of track and interaction between the vehicle and track , it is convenient to consider six sub - systems : the vehicle , wheel / rail contact and representation of excitation , the rail , the fastening system , the sleeper , the sleeper support ( including ballast and substrate ) 轨道及车辆与轨道系统可以分为车辆、轮轨接触面及其激振、轨道、扣件系统、枕木及枕木支撑(道渣道床)等六个子系统组成。
Railway sleepers ( for its hardness , flexbiity and durability ) , kegs especially for liquor ( for its impermeability , hardness and durability ) . poles , posts , furniture , sliced veneer , interior panels , flooring , railway coaches , cabinets , ships , agricultural instruments , handles , coffins and sewing machine tables 铁道枕木(用其硬度?弹性及耐朽性) 、橡木桶、电线杆、平切单板、室内装黄材、橱柜、造船木、农用器具、器具柄、棺木、缝衣机桌板。
