The correlation of engineering properties and mass of ash gourd seeds was explored by using models like linear, quadratic, S‐curve, power, and multivariate. The recorded range of values for seed groups (group of large mass, medium mass, and small mass) was 92.77 to 34.07 g for thousand seed mass, 28.06 to 24.46 for angle of repose, 5.64 to 4.90 m/s for terminal velocity, 213.73 to 227.12 N/mm for hardness. Coefficient of static friction was found the highest for rubber (0.488) and the lowest for aluminum (0.305) for all sizes of seeds. The recommended models based on dimensions were linear, quadratic, and power models with R² = 0.997 based on arithmetic mean diameter for large mass seeds, power model (R² = 0.999) based on geometric mean diameter for medium mass seeds, quadratic and power models with same R² = 0.999 based on arithmetic mean diameter for small mass seeds. The recommended area‐based models for large mass, medium mass, and small mass seeds were quadratic model (R² = 0.997) based on projected areas perpendicular to length, power model (R² = 0.999) based on projected areas perpendicular to thickness, and quadratic model (R² = 0.999) based on projected area's perpendicular thickness, respectively. For surface area‐based models, quadratic model (R² = 0.997) for group of large mass, quadratic and power models (R² = 0.999) for group of medium mass, and quadratic model (R² = 0.999) for group of small mass were found to be acceptable. Models based on ellipsoid volume of seed were recommended for all groups. The properties studied and models explored (best fitted) may be used for process and equipment design.

干灰葫芦（Benincasa hispida Cogn）种子的工程特性：质量建模及其分析

利用线性，二次方，S曲线，幂和多元等模型探索了冬瓜种子的工程特性与质量的相关性。种子组（大，中，小质量组）的记录值范围是千种子质量为92.77至34.07 g，休止角为28.06至24.46，终极速度为5.64至4.90 m / s，213.73硬度为227.12 N / mm。对于所有大小的种子，发现橡胶的静摩擦系数最高（0.488），而铝的最低（0.305）。基于大尺寸种子的算术平均直径，基于尺寸的推荐模型为线性，二次和幂模型，R ² = 0.997，幂模型（R ²= 0.999）基于中等质量种子的几何平均直径，二次和幂模型具有相同的R ² = 0.999基于小质量种子的算术平均直径。对于大，中，小质量种子，推荐的基于面积的模型是基于垂直于长度的投影面积的二次模型（R ² = 0.997），基于垂直于厚度的投影面积的幂模型（R ² = 0.999），和二次模型（R ² = 0.999）分别基于投影区域的垂直厚度。对于基于表面积的模型，对于大质量模型，二次模型和幂模型（R，二次模型，R ² = 0.997）² = 0.999），用于组介质的质量，和二次模型（- [R ²为小的质量的基团= 0.999）被发现是可接受的。推荐所有组基于种子的椭球体积的模型。研究的特性和探索的模型（最佳拟合）可用于过程和设备设计。
