To analyze the response of pavement structure under moving loading, a quarter vehicle model with single freedom degree and unevenness model are established. The dynamic loads are calculated through combining different pavement conditions and speed. When the incentive frequency which is passed to vehicles by the road is close to its own vibration frequency, vehicles will produce the greatest dynamic load.

为了分析路面结构在行车动荷载作用下的力学响应，建立了单自由度1/4车辆模型和以正弦曲线模拟路面不平整度的模型，通过将不同路面状况和行车速度的组合，分析车辆在各情形下所产生的动荷载，发现路面传给车辆的激励振动频率接近车辆自身振动频率时，车辆对路面产生的动荷载值最大。

In this study, we argue that the obligatoriness of le is not due to the necessary realization of T within the verbless clauses and the parametric variation. We, adopting Shen's (2004) and Lin's (2006) frameworks, postulate that le in verbless clauses is actually more like an aspect, denoting "change of slate", and we argue that it is the "perfect" meaning implying "change of stale" that licenses the Chinese verbless constructions.

我们因而提出「NP-了」句式中「了」的出现并非因为时式实现之公要性来允准「无动式副词子句」，反之我们依据Shen (2004)和Lin(2006)的理论视句末「了」为表示「状态变化」的完成体，此「无动式副词子句」事实上是由「状态变化」的语意来允准，这也解释了为何同属於完成体的「过」也可存在於此种「无动式别词子句」。

In the first, the background of this dissertation, the he status which helicopter blade dynamic balance experimental platform system design and using are introduced, helicopter blade dynamic balance experimental platform system is not designed in our country, so in this Dissertation, the advanced experience is accepted and some innovative methods also are used in the system design.

The time space regularity of overlying strata movement and damage induced by coal mining was studied using the dynamic mechanics model. The developing regularty of faults and bed separation as well as surface subsidence caused by mining was analyzed based on the geological and mining conditions of working face 5306 in Xinglongzhuang Coal Mine. The data explaination using the model is more reasonable than that using other models. So it can be used in practical mining activities.
