液体撞击

Impact loading is applied by drop hammer rig.

在落锤装置上进行了充满水的圆柱壳经受大质量低速轴向撞击作用时屈曲过程的实验研究，记录了经受撞击时冲击力和液体内压的时程曲线。

Hydroxyapatite acerate nanoparticles with mean size ranging form 20~50nm are synthesized by the impinging stream devise using emulsion systems consisting of aqueous phase, cyclohexane as the oil phase and OP-10, n-octanol as the nonionic surfactant in definite pH value.

在一定pH值条件下，采用水溶液/环己烷/OP-10/正辛醇四元反相微乳液体系并结合撞击流技术制备出粒径为20~50nm的针状纳米羟基磷灰石晶体。

Compressible fluid with non-return valve Although the use of compression fluid valve pipeline aims to reduce the impact valve flap to a minimum, but can not be compressed fluid selection method with a similar valve to Flanged Ball Check Valves choose.

压缩性液体用止回阀尽管压缩性流体管路选用止回阀的目的在于使阀瓣的撞击减小到最小程度，但可以根据不可压缩性流体用止回阀的类似选择方法来进行选择。

Compressible fluid with non-return valve Although the use of compression fluid valve pipeline aims to reduce the impact valve flap to a minimum, but can not be compressed fluid selection method with a similar valve toFlanged Ball Check Valves choose.

压缩性液体用止回阀只管压缩性流体管路选用止回阀的目的在于使阀瓣的撞击减小到最小水平，但可以按照不成压缩性流体用止回阀的近似选择方法来进行选择。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
