resilin造句

• The energy E stored in the stretched resilin is:
• They make incredible jumps using the protein, resilin.
• Therefore, in this case the energy stored in the resilin of each wing is:
• Furthermore, we will assume that throughout the stretch the resilin obeys Hooke's law.
• But insect wing hinges contain the protein resilin, the most elastic biological material known, Dickinson reported.
• Using a few simplifying assumptions, we can calculate the amount of energy stored in the stretched resilin.
• In the example given, the length of the resilin rod is increased by 50 % when stretched.
• Experiments show that as much as 80 % of the kinetic energy of the wing may be stored in the resilin.
• "The insect wing hinge is known to contain the protein resilin, the most elastic biological material known, " he said.
• Although the resilin is bent into a complex shape, the example given shows the calculation as a straight rod of area A and length.
• He then went to the University of Cambridge in England for four years, where he discovered a rubbery protein, resilin, in insect cuticle.
• Here " Y " is the Young s modulus for resilin, which has been measured to be 1.8?0 7 dyn / cm 2.
• Two synapomorphies are the production of the rubbery cuticle material resilin, and panoistic ovarioles, which lack nurse cells and instead have germ cells forming a continuous tube.
• This is not strictly true as the resilin is stretched by a considerable amount and therefore both the area and Young s modulus change in the process of stretching.
• Typically, in an insect the size of a bee the volume of the resilin may be equivalent to a cylinder 2?0  " 2 cm long and 4?0  " 4 cm 2 in area.
