摘　　要：研究蝙蝠的超声定位特性对智能设备的性能提高具有重要的借鉴意义,精确的生物模型是此类研究的前提.简述Micro-CT的重构原理,并应用该设备与计算机相结合制作了中国大菊头蝙蝠超声波发声器官的数字三维立体模型.该数字模型精确度高,并可根据研究需要变化模型矩阵的大小.该方法及中国大菊头蝠鼻叶数字模型此前国内未见报道.It is useful for referencing the characteristics of a bat＇ s echolocation on improving the performance of intelligent devices, and a precise biological model is the prerequisite for such studies. The principle of image reconstruction was introduced. The images were scanned by a micro-Cr. A 3D digital nose model of the Chinese woolly horseshoe hat, with its vocal organs emitting ultrasonic pause for echolocation, was made using a computer, This digital model has high-precision and could be changed on a matrix scale acCording to the needs of the study. This method and the digital nose model of a Chinese woolly horseshoe bat have not been previously mentioned.
