而在人人讨厌的苍蝇身上竟然也有发明!
And there are inventions in the flies that everyone hates!
昆虫学家研究发现苍蝇的后翅退化成一对平衡棒。当它飞行时平衡棒以一定的频率进行机械振动可以调节翅膀的运动方向是保持苍蝇身体平衡的导航仪。科学家据此原理研制成一代新型导航仪——振动陀螺仪大大改进了飞机的飞行性能LlJ可使飞机自动停止危险的滚翻飞行在机体强烈倾斜时还能自动恢复平衡即使是飞机在最复杂的急转弯时也万无一失。苍蝇的复眼包含4000个可独立成像的单眼能看清几乎360。范围内的物体。在蝇眼的启示下人们制成了由1329块小透镜组成的一次可拍1329张高分辨率照片的蝇眼照像机在军事、医学、航空、航天上被广泛应用。
Entomologists have found that the back wings of flies degenerate into a pair of balance bars. When it flies, the balance bar vibrates mechanically at a certain frequency to adjust the movement direction of wings, which is a navigator to keep the fly's body balanced. According to this principle, scientists have developed a new generation of navigator vibration gyroscope, which has greatly improved the flight performance of the aircraft. LLJ can make the aircraft automatically stop the dangerous rollover flight and automatically restore the balance when the body tilts strongly, even when the aircraft is in the most complex sharp turn. The fly's compound eye contains 4000 single eyes that can be imaged independently and can see almost 360. Objects in range. Under the inspiration of fly eye, people have made a fly eye camera which is composed of 1329 small lenses and can take 1329 high-resolution photos at a time, which is widely used in military, medical, aviation and aerospace.
苍蝇的嗅觉特别灵敏并能对数十种气味进行快速分析且可立即作出反应。科学家根据苍蝇嗅觉器官的结构把各种化学反应转变成电脉冲的方式制成了十分灵敏的小型气体分析仪目前已广泛应用于宇宙飞船、潜艇和矿井等场所来检测气体成分使科研、生产的安全系数更为准确、可靠。大自然真是人类的好老师??
Flies have a very sensitive sense of smell and can analyze ten kinds of odors quickly and react immediately. According to the structure of the olfactory organ of flies, scientists have made a very sensitive small gas analyzer by converting various chemical reactions into electrical pulses. At present, it has been widely used in spaceships, submarines, mines and other places to detect the gas composition, making the safety coefficient of scientific research and production more accurate and reliable. Is nature really a good teacher for human beings??
