This thesis explores the feasibility of using synthetic jet actuators for the propulsion of small underwater vehicles. This work was inspired by the widespread use of pusatile jet propulsion by sea creatures such as squid, salp, and jellyfish. The jets created by these animals utilize vortex rings for thrust production.

由於养殖渔业具有短期供给缺乏弹性、易腐败、不易储存等特性，更因为养殖业的交易性质，大多是在货到当天立即透过价格的调整，将到货量全部结清，所以数量与价格的关系，应该是数量影响价格，故本研究透过逆需求系统求算所有参数。

In the software aspect of 3DP control system, include solid model stratified slicing module, 2D slice data processing module, ink-jet control module, motion control module, etc. Slice module is based on the color STL model output from Magics RP software, its output synusia data is TIFF、JPG、BMP format of CMYK color images. 2D slice data processing module use RIP and dithering algorithm to process 2D color images, thereby achieve the color image information correspond with each micro-nozzle. Ink-jet control module's function is to control each nozzle's on/of.

其中实体模型分层切片模块是基于Magics RP软件输出的彩色STL模型进行的，其输出层片数据为TIFF、JPG、BMP的CMYK格式的彩色图像；二维切片数据处理模块通过RIP算法和抖动算法对一系列二维彩色图像进行数据解析，从而实现图像的色彩信息与每个微细喷嘴的一一对应；喷墨控制模块的功能是控制每个微细喷嘴的喷射与关闭；运动控制模块则负责所有加工成型运动的协调运行。
