本文系统介绍了斜拉空间桁架竖向地震反应的分析理论与方法、详细分析了斜拉空间桁架结构在静力和竖向地震作用下的受力性能，主要内容包括：利用通用有限元软件ANSYS9.0计算了斜拉空间桁架在静力和竖向地震作用下内力及自由端位移分布规律并得出地震内力系数与节间位置、预应力以及斜拉索高度之间的函数关系；详细分析了斜拉索中施加的预应力以及斜拉索高度的变化对于该种结构内力及自由端位移的影响并提出了斜拉空间桁架的临界预应变概念，进而得到了自由端位移与初始预应变以及斜拉索高度的函数关系，即：△=-(40h+2180)ε+9.8；分析了该种结构的动力性能，并指出：在时域内采用直接积分法计算该种结构的动力响应时，应该考虑采用不引起振幅率减小的Newmark-β法，以保证高阶模态响应的贡献仍然保留在响应中而不致于被忽略。

大钻压动力防斜技术增加钻压引起钻柱屈曲，保特钻柱涡动，有井斜时使钻柱产生周期性变化的轴向附加力，无井斜时轴向附加力消失，克服了传统防斜技术中吊打的缺点，提高了钻井速度，达到了解放钻压的目的。

This blowing fan has a hub connected to the rotating shaft of a motor and a number of blades mounted on the outside surface of the hub at fixed intervals to flow air in the centrifugal direction of the fan. Although this fan is produced in a shape of axial fan or diagonal fan by integrally forming the separate turbo blade on the tip or trailing edge of the rotor blade, the blowing noise can be reduced in addition to the increase in the entire wind quantity of the fan by embodying the optimum set angle of the turbo blade.

By studying the deformation and evolutionary sequences around the Panshan granitic pluton, east-central Yanshan orogenic belt, and 40 Ar/ 39 Ar thermochronological test and analysis,we present the structural evolutionary process of the overlying strata before pluton intruded as well as it was intruding. The sequences of regional deformation are as follows: before the intrusion of Panshan granitic pluton, the N-S trend contraction in the east-central Yanshan orogenic belt took place, which resulted in the regional EW-trending Malanyu multi-fold and Jixian thrust fault; then Panshan granitic pluton intruded into the south limb of the Malanyu multi-fold and cut-through the Jixian thrust fault; later, the reactivity of the Jixian thrust fault cut off the synclines around thePans han granitic pluton.
