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.

The stepping-motor-driven warp let-off unit is applied to 1515-PJR flexible rapier loom. The warp tension is measured by using IBM-PC and CRAS software package. A new measuring index of warp tension for comparing the performance of warp let-off motion is given. The statistical analysis on the warp tension in the weaving process from full warp beam to empty is conducted. Also, the spectrum of the dynamic warp tension is analyzed, and the influences of the warp let-off motion' timing on warp tension are discussed.

Just as sound is a wave motion, light in the same sense, may be regarded as a wave motion.

正如声音是一种波动一样，光也同样可以看作是一种波动。

The piston is attached to the top of a connecting rod by a pin,called a piston pin or wrist pin.the bottom of the connecting rod is attached to the crankshaft.the connecting rod transmits the up-and-down motion of the piston to the crankshaft,which changes it into rotary motion.the connecting rod is mounted on the crankshaft with large bearings called rod bearings.

这个活塞被一个叫活塞销或轴颈销的销子连接在连杆的上部。连杆的底部被连接在曲轴上。连杆把活塞的上下运动传递给曲轴转变成旋转运动。连杆通过一个大的叫做杆轴承的轴承（其实就是滑动轴承，分成两个半圆轴瓦）安装在曲轴上。

First we detect the motion region based on Wronskian change detection model in order to eliminate disturbing background and obtain sub-image of motion object.

Take shortcomings,failures,and mockings of others as commonplace and a drive to complete oneself,hold your own opinion over the evalution and disscution divested from others,afterwards sink into the state of eliminate mistakes if any or encourge oneself being not being influenced by the sayinngs of others or having no ideas to do.

把缺点、失败及别人的耻笑等看成是一种常事，当成完善自己的动力，对别人的评价和议论自己心中有主见，做到&有则改之，无则加勉&，不为人言所左右或无所适从。
