特征线法

the lcd display character is acquisited by ccd,after analysis with image process and artificial neural network theory,through grid and intersecting lines to pick up the character′s characteristic,recognize lcd display character,provide with a kind of interface for the instruments and equipments which have no standard interface with the computer but have a lcd display.the experiment result shows that the system acquire and recognize lcd display character is very successfully,and high anti-jamming ability.

摘 要：利用ccd对lcd数码显示字符进行采集，在分析图像处理和神经网络理论的基础上，采用网格法与交线特征提取法，对lcd数显字符进行识别，为具有lcd数显而与计算机无标准通信接口的仪器仪表设备提供一种实用的无线接口。实验表明，系统对lcd数显字符采集方便，识别率高，并且抗干扰能力强。中图分类号：tm932；tp216 文献标识码：b

In the second part, we investigate the neurotrophy mechanism of qingkailing effective composition antagonizing ischemic injury, and comprehensively analyze the experimental results and come to the conclusions as follows: 1. Qingkailing effective composition can promote the activation of astrocyts during the early period after ischemia.

第二部分采用线栓法大鼠MCAO模型，围绕神经营养因子，从不同家族、同一家族的不同成员、同一成员的因子及其受体三个层次，探讨了清开灵有效组分抗局灶性脑缺血损伤的神经营养机制及效应特征。

Included among them are: characteristic frequency curve of reinforced medium; critical length of the anchor bar ; anchor bar density and nonuniform coefficient of the reinforced medium; embedded anchorage layer effect; bed plate effect; weak surface effect; distortion of the bow-shaped distributed state of the anchor bar frictional resistance and initiation, formation and development of the dominant glide control plane; criteria about the displacement velocity of side-wall stability status, critical status and unstability status, and the system of ordinate analysis method, et al

d。文中提出的若干新的概念、判据和分析方法，如加固介质特征频度线；临界锚杆长度；锚杆密度及加固介质不均匀系数；嵌固层效应；垫板效应；弱面效应；锚杆&弓形&受力形态的畸变与优势滑移控制面的产生、形成和发展；边壁稳定状态、临界状态和失稳状态的位移速度判据；纵坐标系分析法等，具有一定的理论价值，并对软土工程围护设计具有指导意义。

By the collected database of images,use the Five-line Seeking-points method to analysis the size and determine the denomination;based on the characters of gray scale of images,take and analyze for judging the face and obverse;Moreover,the gridding metho.

通过对采集的图像数据，采用五线找点算法对纸币大小进行判定纸币的面额；根据加权灰度值提取纸币图像的特征区域判正反；采用网格划分法统计背景点与纸币图像点的数量关系判定纸币的残缺率。

Discussion on some protection problem about power line operating with phase failure ;2. This article describes phasor diagram analysis on two sides of 10 kV distribution transformer with phase failure operation by symmetrical component method.

针对10kV配电变压器的缺相运行，采用对称分量法对变压器高、低压侧断线分别进行了分析，得出各侧电压、电流的各序分量，较全面总结了配电变压器非全相故障运行特征。

Using the technique of natural aging,chloroform and EDTA treatment,well-resolved G-banding patterns were successfully obtained in Rana plancyt's mitosis chromosome firstly.The G-banding patterns appeared distinctive.

采用自然老化、氯仿处理及EDTA显带法，首次在金线蛙有丝分裂中期染色体上成功显示出G带，带纹反差强烈、特征鲜明。

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