日本有一家环境卫生服务公司最近研制成功一种用超声波诱杀老鼠的器具。公司花了二十年才使这个装置合乎理想。这一装置由导管和红外线处理机组成。细长的导管每隔两米就有一个入口,放在地板或壁角等老鼠经常出入的地方;红外线处理机安装在天花板上,一发现老鼠就会命令靠近老鼠的导管入口门打开,并启动入口处的超声波诱导装置,引诱老鼠。老鼠进入导管后,入口门就自动关闭,并以每秒八点三米的速度猛吸老鼠。然后老 An environmental health service company in Japan recently developed a device that used ultrasound to trap mice. It took two decades for the company to make this device ideal. This device consists of a catheter and an infrared processor. The slender catheter has an entrance every two meters, where mice and other places frequented by the floor or corner are mounted. The infrared processor is mounted on the ceiling and when it is found the mouse orders the catheter access door close to the rat to open and start At the entrance of the ultrasound-induced device, luring mice. After the mouse enters the catheter, the entrance door automatically closes and sucks the mouse at a rate of 8.3 meters per second. Then old
