摘　　要：给出了鸣鸣蝉发声肌肌原纤维的双阵列结构，其肌纤维中并存两种不同阵列的“快”和“慢”动肌原纤维（ＦＳＭ和ＳＳＭ）．ＦＳＭ和ＳＳＭ虽然由粗肌丝构成相同的阵列骨架，但细肌丝对粗肌丝的比例（ＲＴＩＦ）不同，分别为３：１和５：１．明显区别于单音调鸣声的蝉类发声肌肌原纤维的ＲＴＩＦ为３：１的单阵列结构，即与鸣鸣蝉变音调声产生的原初机制相适应．The myofibril bilattice structure of sounding muscle in Mingming cicada is given in this paper, and there exist simultaneously two kinds of myofibril,the fast-speed and slow-speed myofibril (FSM and SSM), in sounding muscle fibels. Although the FSM and SSM have identical framerks consisting of thick filaments,the ratios of thin-to -thick filaments(RTTF) are different, i.e. 3.1 and 5.1, respectively. This kind of bilattice structure differs obviously from the myofibril monolattice structure with the RTTF at 3:1 of sounding muscle of cicadas singing in mono-toned song. So, such structure in Mingming cicada is adapted to the original mechanism of vari-toned song production.
