In order to discuss the harm of long-time surfing the internet to the human body, we extract 35 undergraduate in our university and carry on the net continuously experiment. At the same time, 23 people (male 15 person, female 8 person) have been sampled on the track inspection on routine blood index. We discovered that continual 56 hour surfers can c ause obvious blood corpuscle metabolism function disorder, There are radical ascensions concerning the absolute value of blood routine inter cells, the number of white blood cells, the volume and quantity of the blood platelet and so on. The average volume of the red blood cells reduces significantly. The distributing volume and width of the red blood cells increase correspondingly.

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。
