一、砝码质量发生变化后,对测量结果的影响1.由于某种原因,砝码的质量变小了。假设本来50g的砝码变成了49g,而测量人员在测量时还是按照50g来读数的,从而使测量值偏大。2.反之若砝码生锈或粘了脏的物体,从而使砝码质量偏大,假设本来50g的砝码变成了51g,而测量人员在测量时还是按照50g来读数的,从而使测量值偏小。二、调节平衡螺母使天平平衡时,指针没有指到分度盘中央
First, the weight of the quality changes, the impact of the measurement results 1. For some reason, the quality of the weight becomes smaller. Suppose the weight of the original 50g has become 49g, while the surveyors in the measurement or 50g to read, so that the measured value is too large. 2. Conversely if the weight of rusty or sticky dirty objects, so that the quality of the weight is too large, assuming that the original 50g weight has become 51g, and surveyors in the measurement or 50g to read, so that the measurement Value is small. Second, adjust the balance nut so balance balance, the pointer does not point to the center of the dial
