查询词典 back feed

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。

In our experiment, we found two abnormal phenotypes that one only the last three segments develop into pupa, but the other segments are still keep the larva characters; another sample has differently develop speed between abdomen and backside, which resulted in the back develop into pupa but the abdomen were still the larva characters. When we add Az in the feed of injected EcR-dsRNA samples, in the 13 live larvae we found that 6 have the abnormal proleg phenotypes.

在另一组注射EcR-dsRNA以后通过浸叶法添食不同浓度的印楝素，在10ppm处理组存活的13个个体中有6个出现特异表型，其中两个幼虫为不完全蜕皮，尾部体节无法蜕皮导致发育受阻；另外发现4个供试虫体发育至五龄时出现腹足缺失表型，其中有两个是腹足几乎全部缺失，腹足应该生长的部位只有少数几个突起，没有发育成形的腹足；一个出现左侧腹足完全缺失，右侧第二腹足缺失表型；另一个个体只缺失了左侧最后一个腹足。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it.
