1.同时记录了一些昆虫在静止飞行过程中胸部的运动和胸部内的潜在变化。美国蟑螂和蛾的翅膀振动频率在每秒20-40次的范围内，表现出尖峰和运动之间的完全同步，当翅膀被截肢时，这两种现象的频率几乎没有变化或减少。有几只苍蝇和一只黄蜂的翅拍频率超过每秒100次，但它们的尖峰和动作之间并不同步，前者每5-20次翅拍就会出现一次。切断引起的尖峰频率的变化不大或减少，而翅拍频率增加了近100%。而前者的肌肉保留其兴奋性，间接电刺激解剖后，后者的飞行肌肉是不可兴奋的半切胸腔。然而，如果胸部是完整的，苍蝇的间接飞行肌肉可以在自然飞行频率B下驱动。
1. Simultaneous records were made of thoracic movements and potential changes within the thorax of a number of insects during stationary flight.2. The American roach and a moth with a wingbeat frequency in the range 20-40 per second showed complete synchrony between spikes and movements, and little change or a decrease in the frequency of both phenomena when the wings were amputated.3. Several flies and a wasp with a wingbeat frequency above 100 per second showed no synchrony between spikes and movements, the former appearing once in every 5-20 wingbeats. Amputation caused either little change or a decrease in spike frequency, while the wingbeat frequency increased by nearly 100 per cent.4. While the muscles of the former group retain their excitability to indirect electrical stimulation after dissection, the flight muscles of the latter are inexcitable following hemisection of the thorax. However, if the thorax is intact the indirect flight muscles of flies can be driven at the natural flight frequency b...
