衰减

Through comparing and analyzing some experimental data, this paper puts forward that power line has very low input impedance, and it attenuates and jams the signal greatly. Because all these characteristics are time-variable, it's very hard to establish a precise mathematical model.

文中通过对各种实验数据的比较分析，认为电力线的输入阻抗较小，对信号的衰减强，干扰大，且具有很强的时变性，难以提出一个准确的数学模型。

Test results are as follows: Ballastless track structures can effectively improve the dynamic action of train loads on subgrade beds, the measured stresses and acceleration rates are far smaller than those measured with ballasted track structures; axle loads have remarkable influence on dynamic stresses of ballastless track subgrades and have some influence on acceleration responses; speeds of either motor car units or freight trains all have limited effect on dynamic embankment responses; after attenuating over 3 meters high embankment, neither dynamic stresses nor acceleration rates are influential to net cushions at the bottom of column-net structure subgrades

结果表明：采用无砟轨道结构可以有效改善列车荷载对路基基床的动力作用，测得的动应力与加速度值均远小于有砟轨道结构测得的值；列车轴重对无砟轨道路基的动应力影响明显，对加速度响应也有一定影响；无论是动车组还是货物列车，其运行速度对路堤部分的动响应影响均有限；动应力与加速度经3 m 高的路堤后衰减，对桩网结构路基下部的网垫层已基本无影响。

The results show that the vehicle acceleration, the dynamic wheel load and offload factors increase with train speed, and distribute linearly. The safety of train operation and running comfort can meet the requirements when the high-speed train under secondary suspension passing through ballasted track subgrade structure. The dynamic displacement of the system is less influenced by train speed. The dynamic stress of subgrade surface increases with speed improving, and it is distributed as saddle along the lateral direction and as parabola along the longitudinal direction of subgrade surface. The dynamic stress of subgrade declines sharply along the depth of subgrade. The dynamic stress on 3 m depth below subgrade bed surface is about 16 percent of that of subgrade surface.
