Thermal conductivity is measured by the transient hot-wire method, which shows that the thermal conductivity increases with the increase of nanofluid particle volume fraction and temperature. The thermal conductivity of 0.3vol% SiO2-water nanofluid increases by 11.5% at 25℃, while it increases by 46.5% at 50℃ when compared with water at the same temperatures.

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.
