在我们接触的许多教科书,以及万分之一电光分析天平使用说明书中,万分之一电光分析天平的读数都是读至小数点后第四位。如上海天平仪器厂生产的TG—328A型万分之一电光分析天平,它的使用说明书上就说明该天平读数读至小数点后第四位。我们认为,它的读数读至小数点后第五位更合理。通常,我们在测量读数时,都是在测量工具最小刻度后再估读一位(除了如游标卡尺、螺旋测微器等已等
In many of the textbooks we contact, as well as one hundred ten electro-optic analytical balance instruction manual, one hundred ten electro-optical analytical balance readings are read to the fourth place after the decimal point. Such as the Shanghai Balance Instrument Factory TG-328A type one hundred thousandth electro-optical analytical balance, its instructions on the instructions read the balance to the fourth place after the decimal point. We think it is more reasonable to read its readings to the fifth decimal place. Normally, when reading a measurement we re-evaluate one after the minimum scale of the measuring tool (except for such things as a vernier caliper, a micrometer, etc.)
