判别鸡胚蛋性别的血线方向函数的进一步改进
Further Improvement of Gender Distinguishing of Hen′s Embryo in Egg by The Directional Function of Its Blood-Vessels
【摘要】 将判别鸡胚蛋性别的血线方向函数在已取得的结果上进一步改进 ,在不降低准确率的前提下 ,减少参变量的个数 ,使得判别函数更简单 ,以便于实际应用的转化 ,同时 ,也进一步说明鸡的性别主要依赖于哪几个血线的方向数 .
【Abstract】 Further improvement being carried out in this paper for the achievement obtained to establish the directional function of blood-vessels for distinguishing the gender of egg′s embryo. On the condition of the degree of accuracy of judgment not being reduced, we reduce the number of parameters in order to simplify too much extent of the discrimination function. So that it will be more adoptable for actually application, meanwhile it reveals that on which blood-vessels do the gender mainly depend.
