研究了密度与西瓜内在品质的关系。西瓜的密度被发现与空心度和可溶性固形物含量有关，可溶性固形物含量可用作甜度的量度。西瓜的可溶性固形物含量可以通过密度和质量的多元回归分析来估计。一个最佳的密度范围被发现，这提供了一个指标的西瓜质量。提出了一种新的球形水果密度分选的电学方法，即用电容测量体积，用电子天平测量质量。研制了一种新的西瓜空心度密度自动分选系统，该系统可将空心度较低或果肉疏松变质的低密度西瓜剔除，并可测定西瓜的可溶性固形物含量。该系统经过测试，结果令人满意。
The relationship between density and internal quality of watermelon was investigated. The density of watermelon was found to be related both to the degree of hollowness and the soluble solids content which can be used as a measure of sweetness. The soluble solids content of watermelons can be estimated from density and mass by multiple regression analysis. An optimum range of density was found which provides an indication of watermelon quality. A new electrical method is proposed for density sorting of spherical fruits, which measures the volume by electric capacity and mass by electronic balance. A new automatic density sorting system was developed for measuring the degree of hollowness, which enables low density watermelons with cavities or deteriorated porous flesh to be removed and permits the soluble solids content of watermelons to be estimated. The system was tested with satisfactory results.
