Following a path made by crossties , you can first reach the sight seeing pavilion where you can have a comprehensive view of the garden 沿著废枕木铺成的步道一路往上爬，首先到达的观景台，由此可以俯瞰整个苗圃的风貌。
Another is the discrete model . considering the interaction between the sleeper and the sleeper support , it can be modeled as discrete model 另一种为离散化模型；考虑枕木与枕木支撑? ?道渣道床相互间的作用，将系统简化为离散化模型。
In accordance with the dominant equations of the two models , this paper uses green function method to calculate vibration caused by effects among wheels , tracks , and sleepers 本文根据两种模型的控制方程，使用green函数法计算了车轮、轨道、枕木的相互作用所引起的振动。
In the baggage cars , kelps , fishplate , rolled iron , sleepers , wire rods , plates and sheets , laminated articles , hot rolled hoops , splints and mortar carriages , and zor s ore 车里装着海带、鱼尾板、钢材、枕木、盘钢、厚金属板、叠合材料、热轧钢箍、软木条和迫击炮车，以及佐泽斯矿石。
3 the interaction of the rail system " s component is discussed furthermore . the two - dimension model is put up . the result is compared with euler beam modulus , satisfied results has got 3进一步分析了轨道系统中车轮?轨道?枕木之间的相互作用，提出了轨道系统的二次梁模型，结果与euler梁模型进行了对比，得到了良好的效果。
