Computers imitate human brains, camouflage uniforms imitate zebra stripes, and bionic bats create radar and eggshell buildings of Sydney Opera House. Biologists have made high-grade silk threads, tear-resistant parachutes and high-strength cables for temporary suspension bridges through the study of spider silk. Ships and submarines are modeled after fish and dolphins. The rocket takes off by using the recoil principle of jellyfish and squid. Researchers have developed many military camouflage equipment for the army by studying the chameleon's color-changing ability. Scientists studied frog eyes and invented electronic frog eyes. Termites not only use adhesive to build their anthills, but also spray adhesive on their enemies through small tubes in their heads. So people made a working weapon-dry rubber shell according to the same principle. The US Air Force has developed a miniature thermal sensor through the "hot eye" function of poisonous snakes. Drawing lessons from the bionics principle and the fur structure of terrestrial animals, Chinese textile scientists have designed a small barrel warm fabric with the functions of wind resistance and moisture conduction. According to the principle that the rattlesnake's buccal fossa can feel the temperature change of 0.00 1℃, human beings invented the tracking and chasing rattlesnake missile. Humans also used the principle of leapfrog to design a toad rammer. Humans imitate the highly sensitive sense of smell of police dogs and create "electronic police dogs" for investigation. Scientists have made the first batch of gas masks in the world according to the unique drug detection ability of wild boar nose.
