Some are pleated Katharine Hepburn pants with wide bottoms.

有些是臀部加大的凯瑟琳?赫本(KatharineHepburn)裤.

When the temperature was lower than the T g of soft segments in PU, both the size and the relative concentration of free volume increased with increasing temperature for PBU and PCU.

当温度低于PU软段的Tg时，两类PU的自由体积尺寸和浓度都随温度升高而增大。
