人心果果实体积测定方法的探讨

Study on the Method Testing the Volume of Fruits of Sapodilla

通过测定人心果果实实际体积、果实纵径和相互垂直方向上的果实最大横径(D1和D2),经过矫正法和线性回归法推导果实体积估算公式。结果表明矫正法和线性回归法推导的圆球形果实体积公式、线性回归法推导的椭球形果实体积公式能够准确估算果实体积;应用这些公式要求样本容量不低于10。

Through testing the true volume and the length and the sectional diameters （ D1 and D2 ） of fruits, the formulas for estimating the volume of fruits are concluded by the corrected coefficient method and analysis of linear regression. The formulas for the ball - shaped fruits from the corrected coefficient method and the analysis of linear regression method are used to estimate the fruits volume precisely. The formula for ellipsoid - shaped fruits from the analysis of linear regression method are used well too. It requires that the sample capacity is 10 at least.
