Connaughton (1994) and Sprague (2000) mentioned that the differences of length, weight, and tension of the sonic muscle and the amount of protein and glycogen affect the types of sounds emitted. To reveal the producer of high-frequency sound, this research analyzed and compared the length, width, thickness and somatic of sonic muscle and the amount of protein and glycogen in seven sciaenid species occuring on the west coast of Taiwan (Johnius tingi, Johnius sina, Johnius amblycephalus, Johnius amblycephalus, Pennahia argentata, Chrysochir aureus, and Otolithes ruber), then to find if the differences of physic parameter and energy supplication are the major factors making O. ruber produce high frequency of sound.

在Connaughton (1994)和Sprague (2000)研究报中指出造成石首鱼产生不同型态的声音主要取决於发声肌肌纤维的长度、重量、张力、蛋白质与肝醣含量的差异性,为了证实高频声音确实为红牙鱼或所产生,本研究将分析比较在台湾西岸海域其他不同石首鱼(红牙鱼或、黄金鳍鱼或、白姑鱼、中华叫姑鱼、皮氏叫姑鱼、丁氏叫姑鱼与顿头叫姑鱼)发声肌之长度、重量、蛋白质与肝醣含量差异,探讨发声肌在物理参数与能量的供应的差异是否为造成红牙鱼或产生高频鸣音之主要因素。

On the basis of previously research, this paper re-probe into the mechanism of electro-chemist mechanical manufacturing process, making the rational technological parameter, and developing the manufacturing equipment. Through a lot of technology tests, get a lot of labratory data, accordingly, researched the surface feature of the electro-chemist manufacturing process, and deeply discussed its influence on the work piece feature. The last result is that: the electro-chemist mechanical manufacturing process can reduce the low-frequency component significantly, but on high-frequency component, it has little influence, having obviously positive pole flat effect. After manufacture, the tip parts on the surface of the work piece is cut off, there is micro "high land" shape, the parameter for surface roughness is reduced a lot, the surface outline of the work piece is negative, the bearing length rate is cliffy. Also the surface quality of the work piece is improved. This can help to avoid changing the shape, improve the feature of rub, gear and reduce the time to suit. This would also ensure the precision and result in a longer work piece life.

在以前研究的基础上,本论文重新探讨了电化学机械复合光整加工工艺的机理,确定了较合理的工艺参数,对电化学机械复合光整加工设备进行了改进,通过工艺实验广泛地搜集了大量实验数据,依据实验数据,多角度地研究了电化学机械复合光整加工的表面形貌特点,并且从理论上深入讨论了电化学机械复合光整加工表面形貌对工件工作性能的影响,最后得出的结论为:电化学机械复合光整加工对工件原始表面的低频成分有较大程度的降低,而对高频成分影响较小,有明显的阳极整平作用,被加工工件表面的尖峰状凸起被去除,工件表面呈现出微观&高原型&,表面轮廓不平度高度特性参数大幅度降低,工件表面轮廓分布集中,且呈负偏态,轮廓偏斜度为负值,轮廓支承长度率曲线陡峭,工件的表面质量得到综合改善,这对提高零件的抗接触变形能力、改善摩擦、磨损性能、降低工件的磨合时间、提高工件的精度保持性、延长工件的寿命均有利。
