The results indicate that lgG'-,lgG-lgw relation-ship curves look as straight lines on the double logarithmic scale at lower mas fraction of fumed silica.In the higher angular frequency region,therer is a slight downward discrepancy for the curves from the straight line.With the increase of the fumed silica mass fraction the lines are upward translation,but the slopes decrease.

The results showed that water content decreased first, then increased in the gastrula stage of embryonic development, reached the highest content at the second phrase larvae stage and then began to decrease from the third phase larva stage. The content of lipid in the dry weight increased with the embryonic development stages, but decreased at intramembranous nauplius stage, the second phase larva, and the infant stage of larvae development. The rate of lipid in wet weight decreased and the content of C20:4w6、20:5w3 and C22: 6w3 decreased.

结果显示，黑斑口虾蛄在胚胎和幼体的发育过程中，水的体积分数先降低，至原肠胚期开始升高，到第二相幼体期达到最高，之后又有所回落；脂类占组织干重的比率呈升高趋势，但分别在膜内无节幼体、第二相幼体和仔虾蛄期略有降低；脂类占组织湿重的比率呈降低趋势；花生四烯酸、EPA和DHA的体积分数都呈降低趋势。
