问:如何正确读取玻璃液体温度计的示值? (陕西林奇) 答:要想获得准确的读数,温度计的插入必须要垂直。读数时,要读取有机液体的凹月面和水银的凸月面顶部对应的温度标尺上的示值。用读数望远镜读数时,首先应调节,使其处于水平位置,然后通过望远镜的中心读取示值。用放大镜读数时,视线要通过放大镜的中心与感温液弯月面顶部相切,并且视线应与温度计相垂直。借助于上述放大装置读数时,均要估读到温度计分度值的十分之
Q: How to correctly read the glass liquid thermometer indication? (Shaanxi Lynch) Answer: To obtain accurate readings, thermometer insertion must be vertical. Reading, read the liquid surface of the meniscus and mercury on the top of the convex lunar surface temperature scale corresponding indication. When reading with a reading telescope, first adjust it so that it is level and read the indication through the center of the telescope. When reading with a magnifying glass, the line of sight must be tangent to the top of the meniscus of the thermometer through the center of the magnifying glass, and the line of sight should be perpendicular to the thermometer. With the above amplification device readings, should be read to the thermometer divider value of ten
