In order to judge the grade of pimento, some parameters are extracted from two-dimensional image of pimento. These extracted parameters consist of length, width, perimeter, projected area, projected area to squared perimeter ratio, and width to length ratio. The extracted parameters and grade of pimento judged by experienced workers are used as input and desired patterns to estimate the connection weights of neural network. In this paper, a three-layer feed-forward neural network and back-propagation learning algorithm are suggested for the shape and size grading of pimento.

本文以青椒为对象，首先利用数位影像处理技术从人工分级后的各等级产品的影像中萃取出周长、投影面积、长度、宽度、投影面积对周长平方比与宽度对长度比等可作为判断青椒等级的分级准则，再利用多层前馈式类神经网路来模拟农产品的分级作业，并采用反向传递演算法学习各项分级准则与等级判断结果间的关系，以量化了解各项分级准则对等级判断结果的影响程度。

The formula for area of ellipsoidal triangle on earth ellipsoid by means of geodesic coordinate is derived in this paper. It is showed that the primary term is identical with the formula for area of plane triangle by planimetric rectangular coordinate in three angular point, while the expression of remainder terms has also regularity of its form. The presented formula can be applicable also to convex polygon on earth ellipsoid.

本文推导出用三顶点的测地坐标计算地球椭球面上三角形面积的公式，公式表明，其主项的表示式与按平面坐标求面积的计算式完全一致，而附加项的表示式亦有规律可循，因此该公式的适用范围可由椭球面三角形推广至椭球面上任意凸多边形。
