一、简化计算目前粒径的计算(或查表)法既麻烦又不精确,在此向大家推荐一种以查表为基础的简化计算方法(见表1)。比重计读数与有效深度可根据校正曲线的对应点得出。温度可根据当地室温范围选定,不是整数时可用内插法估算。可同时列 I. Simplified Calculations The calculation of the current particle size (or look-up table) method is both cumbersome and inaccurate. We hereby recommend a simplified calculation method based on a look-up table (see Table 1). The hydrometer reading and effective depth can be derived from the corresponding points of the calibration curve. The temperature can be selected according to the local room temperature range. If it is not an integer, it can be estimated by interpolation. Simultaneous column
