There are several sources of potential error in calculating the concentration or energy value of floral nectar. Errors resulting from confusing data become substantial with increasing concentration. The different methods of expressing sugar concentration are here clarified, and the correct methods of converting from one to the other are provided. Refractometers in use in field studies usually read on a weight per total weight basis; this is recommended as the mode of statement. The perils of oversimplifying conversions from this mode, as is often done, are pointed out.
在计算花蜜的浓度或能量值时，存在几种潜在误差来源。随着浓度增加，因数据混淆导致的误差会变得很大。这里明确了表示糖浓度的不同方法，并提供了从一种方法转换为另一种方法的正确方式。野外研究中使用的折射仪通常按总重量中重量的比例读数；建议以此作为表述方式。指出了像经常做的那样过度简化从这种方式进行转换的风险。
