摘要：

目的 探讨人大脑半球脑回形态观察的新途径，了解脑回形态的二元一次函数表述。 方法 以人大脑半球枕叶脑回为观察对象，利用脑后面特殊标志作坐标并测量，得出同一部位脑回二元一次函数，进行分析并归纳特征。 结果 得到枕叶降回形态变化的函数斜率和tan值，从而表示出脑沟的走向和曲折程度。结论 二元一次函数能描述人脑脑回的形态特征，可以作为脑回形态表述的方法之一。

Abstract:

Objective To investigate a new method to show morphology of gyri in human brain. Represent the pattern of gyri described by linear equation of two unknowns.Methods Occipital lobe and posterior landmarks of brain were observed and served as coordinates and measurement, linear equation of two unknowns about the gyri on the same site was given, and analyzed. Results Morphological functions gradient and tangent value of descending gyrus of occipital lobe are obtained. Conclusion Linear equation of two unknowns can be used to describe morphological features of human cerebral gyri, and as one of methods to show morphology of gyri in human brain.
