使振动

This thesis aimed to discuss an electromagnetic energy harvester. Motion of a fluid driven by a 30 Hz pulse pump is used to activate the electromagnetic energy harvester. The periodic motion of the fluid in the chamber causes a harmonic vertical deflection in the diaphragm on which a permanent magnet is attached. Subsequently, the vibration of this magnet induces an output voltage in a solenoid hanging above it.

中文摘要本文是探讨电磁式能量产生器的机构，此电磁式能量产生器的主要作动方式为藉由频率30Hz的脉冲马达驱动工作流体，使工作流体呈周期性的流动让帮浦腔体上致动薄膜产生周期性的上下往复运动，因此帮浦腔体内产生压力周期性的变化，在薄膜上永久磁铁的振动，使得螺旋线圈感应产生电压的输出。

The results show that the effect of addition or no-addition of degasser on grain refinement of Al-5.0%Si alloy ingot is...

结果表明，除气剂的添加与否对Al-5%Si合金铸锭组织的细化没有影响，铸锭由粗大的柱状晶组织构成；采用合适的超声波处理时间，Al-5%Si合金铸锭的等轴晶获得率大幅度提高，可使整个铸锭组织变为细化的等轴晶组织；超声波振动时间过长将导致铸锭内气孔的增加；根据克劳修斯-克拉柏龙方程，某一强度的超声波引起的压力冲击波作用，导致液相转变为固相，引起了超声波的细晶作用。

With the different laboratory compaction method and the real pavement, the study of particle stability and density indicated that Marshall compacted specimen can not simulate the real pavement, the rolling and gyratory compacted specimen are the most similar with real pavement, vibrating compacted specimen is second similar with the real pavement.

针对不同试验室压实方法成型试件和实际路面，从集料颗粒的稳定性和密实程度两个角度的对比研究表明，马歇尔击实成型试件法无法有效模拟实际路面，表现在其粗集料颗粒主轴取向无统计规律且与实际路面不具相关性；轮碾压实和旋转压实试件具有与路面最接近的稳定性和密实程度；振动压实次之，虽然表现出具有使颗粒较好均匀分散成型的特点，但其粗集料颗粒骨架的稳定性不够理想，致使其密实程度相对不高。
