(三)特异的“皮肤”——温度、压力传感器人的皮肤能感觉出外界温度、压力、拉力等的变化,而温度传感器和压力传感器则能比人的皮肤更灵敏、更精确地感觉到这些变化。比如,在高温下,温度传感器能把人的皮肤根本不能接触的冶炼温度准确且迅速地检测出来;压力传感器能将人的皮肤感觉不到的微小应力反映出来。所以这些传感器就为精密地 (C) Specific “skin” - temperature, pressure sensor Human skin can feel the outside world temperature, pressure, tension and other changes, while the temperature sensor and pressure sensor is more sensitive than human skin more accurately Feel these changes. For example, at high temperatures, temperature sensors detect smelting temperatures that human skins can not touch at all times accurately and quickly; pressure sensors can reflect the small stresses that people do not feel in their skin. So these sensors are fine
