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 results show that a separate dunk is observed near the stagnation point of the second sphere on the distance of spheres L≤2.5D because of the influence of reverse pressure gradient.

结果表明：当L≤2.5D时，由于逆压梯度的影响，在第二个圆球滞止点附近捕捉到附体分离泡；由于第二个与第三个圆球的置入，展向压力梯度诱发第一个圆球背风面流动的展向输运，且随着圆球间距的增加流场的展向输运趋势减小，但涡的强度增大；第二个圆球与第三个圆球背风面流动没有明显的展向输运；湍动能的增量与圆球间距近似成平方规律。

The second assassin is the Pontificate "aiming the square of steel at the heart of the victim".

第二个杀手是教宗"瞄准的平方钢的心脏，受害人"。

If A is a symmetric positive definite matrix, then the quadratic form x~ TAx can be written as a sum of squares. Equivalently, A is a sum of rank one matrices VV~T.

若A是对称正定矩阵，则二次型x~ TAx 能写成平方项的和，即A是秩为1的矩阵VV~T的和。

And, power dissipation is a square function of the voltage.

当然，电源损耗与电压的平方成比例。

Why does the field force is in inverse proportion to the square of the distance between the two masses, but not to three or four power of ones and to prefigure that the constant G of the gravitation isn't invariant.

概述：此文章描述了引力的动力过程，阐述了引力质量是惯性质量的一种表现形式；场力为什么与作用距离的平方成反比，而不是与三次方、四次方成反比；并预示了万有引力常数G并不是真正不变的常量等等。

The gravitational mass is an embodiment of the inertial ones. Why does the field force is in inverse proportion to the square of the distance between the two masses, but not to three or four power of ones and to prefigure that the constant G of the gravitation isn't invariant.

Furthermore, we solve the user equilibrium problem by gradient projection method to obtain some additional path-based information. Since true OD trip demands are unknown, we conduct OD demand estimation and OD demand covering rate verification by the least square estimator.

在求解使用者均衡之交通量指派问题上，透过梯度投影法(Gradient projection， GP)求解，并获得以路径为基础的相关资讯；在流量倒推旅次起迄量的课题上，由於真实OD量未知，故使用基本的最小平方估计量，进行旅次起迄需求涵盖量的推估与检验。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
