一、前言在精密科学与应用科学的不同领域中,越来越多地使用先进的单盘电子秤(分析或微量分析用的)。因为它能使高精度质量测量自动平衡并把测量结果快速读出、打印并由计算机处理。电子秤的一个突出特点是依照电磁原理工作,不用砝码,从而不能直接使用采用砝码的机械秤计算空气浮力对测量结果影响的修正 I. INTRODUCTION In different fields of precision science and applied science, more and more advanced single-plate electronic scales (for analysis or micro-analysis) are used. Because it automatically balances high-precision quality measurements and quickly reads out the measurements, prints them and processes them on a computer. A prominent feature of the electronic scale is in accordance with the principle of electromagnetic work, without weights, which can not be used directly to calculate the mechanical buoyancy scale air buoyancy correction of the measurement results
