Using the models, the author has also calculated the vibration response to high speed railway vehicles of three types travelling over simply-supported beam bridges with various span lengths respectively. Based on the analysis of the computation results, the concept of resonance velocity of a bridge under a high speed running vehicle is present, and it is pointed out that comparatively great vibration of bridges on high speed railways is caused by bridge resonance resulted from the static force pulsating. In a vehiclebridge coupling vibration system, the damping constant of the axle spring is the main factor affecting the response variable of bridge velocity resonance, and the influence of track irregularity on bridge vibration on high speed railways is rather smaller.

利用所建立的计算模型，计算了三种形式的高速铁路车辆通过各种跨度简支梁桥结构时的振动响应，对所得到的计算结果进行了详细的分析，提出了高速行车下桥梁共振速度的概念并指出高速铁路桥梁产生较大振动的原因是静力脉动引起桥梁共振造成的；通过研究车—桥耦合振动系统方程的参数后指出，在车—桥耦合振动系统中，车辆—系阻尼的大小是影响桥梁速度共振时响应大小的主要因素，轨道不平顺对高速铁路桥梁振动的影响较小。

The conversions of ice temperature and ice velocity occur from bridge to trough of terrain on the eastern Nyainqentanglha Range. The ice temperature at bridge is lower. The ice at bridge starts to move due to the larger gravitational driving stress. During the course from bridge to trough of terrain, basal ice temperature rises because of the friction. While reaching the pressure melting point of ice, basal decollement occurs, and higher velocities can still be produced at trough.

而位于念青唐古拉山东部地区的冰川，冰温和冰速从地形脊到地形槽处发生了较大的转化过程，在地形脊处冰温较低，受重力加速度的影响，冰川开始产生滑动，从地形脊到地形槽滑动的过程中，其底部受摩擦加热的影响，底部冰温升高，达到融化点，底部产生变形，到地形槽处仍会产生较大速度的滑动，因此冰川的运动从地形脊到地形槽处发生了转化，即地形脊处的滑动属动力过程引起的滑动，而地形槽处的滑动属热力过程产生的滑动。
