果蝇纤维毛状爪垫与不同粗糙度表面接触的黏附力研究(英文)

A study on adhesive force generated by fly hairy pads contacting surfaces of different roughness

总结了昆虫爪垫与接触面的黏附现象以及可能的黏附机理.在回顾了现存黏附力的测试方法后,本文提出了2种自制测试装置并测量了黑腹果蝇(双翅目,果蝇科)与不同粗糙度表面接触的黏附力.2种测试装置中,第2种天平测试法简单有效,为本文所创.文中描述了测试装置的特点和具体的测试过程,测试结果也同其他测试方法得到的结果进行了比较分析,并做了进一步的阐述和总结.

We first summarized briefly the general phenominon of insect attachment to surface so as to investigate the nature of the interactive forces involved. After reviewing the existing meth- ods in testing such attachment forces ,we reported two custom-built devices to measure the pure adhesive forces of fruit flies, Drosophila melanogaster （Diptera, Drosophilidae）, grasping to sur- faces of different roughness. Of the two devices, the balancing lever method, simple but effec- tive,is used for the first time as we know. The characteristics of the devices and the measure- ment processes were discussed in detail. The data measured were examined and compared with previously published results. Some elucidations and conclusions were drawn based on the data at the end.
