At last, all related problems due to ship type and towing speed influencing the quality of captured images and results were discussed. A ship model with V-shape bottom and protruding keel might cause some disadvantages for PIV measurements. The use of longer laser light ducts extending deeper is a possible solution. A ship model with light yellow paint will cause the unproportionate of light and will cause white background on captured images. It is suggested to re-paint the ship model in black or dark colors to solve this problem. In high-speed test conditions, a ship model's bow waves entrain large amount of air bubbles into water and those bubbles will block the view of camera causing some random black spots in the images. Thus, it is necessary to remove the useless black spot data and repeat the same test condition if statistics requires enough number of images.

本文讨论建立此系统之技术及实验方法，设备的架置方式和配置为一可调性调整之开放式架构，质点施放方法以一自制的施放架於实验前先布置於测试段中，并制定一实验流程规范，再分别针对实验所得滑航型及排水量型船模的流线方向及切流线方向各不同位置及船速之速度进行流场分析；实验结果发现不同船型会造成不同的实验困难：船形上突起之龙骨及V形船底会遮住照明光线，可利用较深之导管调整光页角度改善；而浅色船模表面会造成光线的不均匀，可以更改船模涂装颜色改善；高速实验的气泡会不定点的遮住光线，须先除去无资料区域并使用更多资料组数来改善。

Perhaps i say like this,it's not honesty.my heart just the same feel a little lose.when all is said and done,it's a decision which is forced to make up.it's not my voluntary.it always ask us to think that we are the people to be cast away.at the same time,because of my parents,i also hope to accompany with them when they are still healthy.so i also lean to come back to china.on the other hand,i can understand the decision of the school.after all the school broke ground only a short time,it has many necessary consumption,it needs many money to supply.but we are too valuableness for the school,even if we are not satisfied with the treatment and the salary.only for the situation that school has not gived us any explanations,and then has made the decision.i think it is not done.kick down the ladder,it's not a good feeling.well,china has a old saying,"gather well,and fall apart well."
