2.The basic structure and working principle of biomimetic fish fin is briefly introduced.
3.Then, the tip deformation error of the shape memory alloy (SMA) plate pair used as fin actuators is computed theoretically to improve the deformation precision of the SMA biomimetic fish fin.
4.In the ideal case the boundary line between the colours will be in half of the fin length, in all fins.
5.The climbing perch "walks" by standing up on its fins and moving its tail back and forth .

9.We manufacture condensers and evaporator coils of Fin and Tube type, Mini Air Cooled Condensers (MAC), FHP Condensing Units, Automotive HVAC systems and OEM Refrigeration equipments.
10.Those who had caught sharks had taken them to the shark factory on the other side of the cove where they were hoisted on a block and tackle, their livers removed, their fins cut off and their hides skinned out and their flesh cut into strips for salting.
