Bionics is a recently developed branch of science, which has tremendous potential for improving the life of mankind in our contemporary society. Bionics can be described as the study of systems in living creatures and the application of the knowledge gained from this study to the improvement of various kinds of man-made systems. The term bionics was coined around 1960, and much of what is known about the science of bionics has been discovered since about 1970.
Some researchers recently have studied the eyes of the common frogs and have discovered that a frog’s eyes only find moving things such as insect-shaped objects and large, threatening objects. As a result of studying the eyes of frogs, scientists have constructed a simple electronic model of a frog’s eyes which can track airplanes circling above an airport and then provide information to computer-run air traffic control systems. Someday such electronic eyes may provide the means to automatically guide automobiles by providing information about objects moving toward the automobile. Other scientists have studied the compound eyes of some insects and crabs and have built a seeing machine that is a simple model of the horseshoe crab eye.
The hearing of a number of creatures also has been studied extensively so that hearing machines can be developed. Bats have unusual hearing which can extend into the ultrasonic (超声的) range. The dolphin also has been studied extensively, and dolphins are able to navigate through water extremely effectively. Radar and sonar(声 纳) systems which are used to help ships and planes navigate have been based on the sonar systems of both bats and dolphins.
Which of the following could be the best title?
选项
A、Electronic Eyes
B、The Science of Bionics
C、Sonar Systems
D、The Hearing of Some Creatures
答案
B
解析
