However, the situation reversed in roots uptaking PAHs. With close lipid concentrations, leaves with pubescence or rough surface were found to have stronger capability in uptaking PAHs than the others, and the capability of the fibre was stronger than the taproot.

脂肪含量相近时，表面粗糙或具有细密绒毛的叶片富集PAHs的能力较强，须根系根吸收PAHs的能力强于直根系根。

The weight of the composite films increases with the decrease of temperature and the increase of current density and pyrrole monomer concentration.

与纯PPy膜相比，PPy/MWCNT复合膜有更好的电子传递行为，而复合膜表面更加粗糙、疏松。

This requires Film thickness in the order of four or more times greater than the average surface finish values of the ball and raceway.

这要求油膜的厚度要比滚珠和滚道的金属表面粗糙度厚4倍，甚至更多。
