物理计算题是通过物理定律、公式的运用与计算,研究物质运动的各量间的关系。它的最后结果不只是数量关系的表达,而且还有着实际的物理意义。因此,就不能简单地套用一些数学常用的法则,而应具体分析按其实在的物理意义进行处理。下面列举几种常用的处理计算结果的方法,以供参考。一、求平均值的方法多次测量,用求平均值的方法来处理测量数据,进而缩小测量误差。值得注意的是:若求平均值时除不尽,应计算到比测量值的位数多一位,然后四舍五入,保留与测量值相同的位数,以此表示测量工具的
Physical calculation is through the use of physical laws, formulas and calculations to study the relationship between the amount of material movement. Its final result is not only the expression of quantitative relations, but also has practical physical meaning. Therefore, we can not simply apply some common mathematical rules, but should be specifically analyzed according to their actual physical meaning for processing. Here are some commonly used methods to deal with the calculation results for reference. First, the method of averaging multiple measurements, with the average method to deal with the measurement data, and then reduce the measurement error. It is worth noting that if the average value is not exceeded, one bit more than the number of measured values should be calculated and then rounded off, leaving the same number of digits as the measured value to indicate that the
