To elucidate the relationship between otolith microstructure and microchemistry and the life history events of the grey mullet Mugil cephalus in the early stage, the daily growth increments, growth check, Sr/Ca ratios and trace elements in otoliths of the juvenile mullets collected from the four estuaries from NE to SW Taiwan coast from 1996 to 2004 were examined by using the light and electron microscopes, electron probe microanalyzer and laser-ablation inductively coupled plasma mass spectrometry. A transition check was found in otoliths of all mullets.

为了阐明乌鱼耳石微细构造、微化学与其初期生活史事件之关系，本研究於西元1996年至2004年在台湾东北至西南沿岸的四个河口域进行乌鱼稚鱼的采样，然后利用光学及电子显微镜、电子微探仪及雷射熔蚀-感应偶合电浆质谱仪分析稚鱼耳石的日周轮、锶钙比及微量元素组成之变化。

The different performance between HZSM-5 catalyst and HL catalyst is mainly due to the different acidity, specific surface and micropore volume which they have.

这种反应性能的差异主要是由于HZSM-5沸石和HL沸石的酸性特征、表面积和微孔体积不同所造成的。
