The main researches about Chinese character recognition of vehicle license plate and its corresponding technique in this paper are as follows:(1) The pre-processing for image is essential before character recognition. This paper firstly uses the experience knowledge to give a roughly orientation,then set a carefully orientation based on Otsu arithmetic,finally get the whole clear license plate.In order to solve the problem of character extraction,the fly-back method is put forward:the experience knowledge is made the best of.(2) An algorithm of feature extraction from grayscale image based on optimization Gabor filters is proposed.

本文针对车牌汉字识别及相关技术进行研究，主要工作包括：(1)在对车牌汉字进行识别前需要进行必要的预处理工作，我们首先运用车牌的先验知识进行粗定位，然后采用Otsu阈值二值化方法等进行快速鲁棒的车牌区域细定位，获得完整、清晰的车牌轮廓，并采用回扫式字符切割方法，充分利用了车牌字符固有的特点准确找到各个字符的分割点，为特征提取奠定了基础；(2)提出一种优化的Gabor滤波器特征提取算法直接对灰度图像进行特征提取。

Rats with CHF were divided randomly into two groups, one group was injected dexamethasone(1mg /kg) intramuscularly at the first and forth day respectively,the other group was injected equi-volume saline likewise, and observing the changes of symptoms of rats with CHF; measuring rats hemodynamics index including blood pressure, heart rate and left ventricular end-diastolic pressure 4 days later. Part 2: To measure every group rats myocardialα1、β1、β2、β3-AR density by immunohistochemical method ,and to understand the AR density changes .Taking the first part rats'myocardium tissues for testing myocardialα1、β1、β2、β3-AR density and 5 normal rats for normo-contrast group and taking gray scale of slice as AR density. Part 3: The study enrolled 35 patients with DCHF. Patients were included if they had orthopnea and refractory edema due to acute DCHF that was severe and had taken more 1 week hospitalization and intravenous therapy in addition to diuretics.

观察心衰大鼠的症状，4天后对两组大鼠进行血流动力学检测，检测指标包括血压、心率和左室舒张末压；第二部分：取第一部分实验动物大鼠的心肌组织，并取5只正常大鼠的心肌组织作为正常对照，用免疫组化法检测大鼠心衰前后及糖皮质激素治疗前后大鼠心肌组织肾上腺素能受体α1、β1、β2、β3受体的变化，取镜下切片的灰度值反应受体的密度；第三部分：研究对象为临床难治性心衰病人35例，病人的选择标准包括由于急性失代偿的心力衰竭出现的端坐呼吸，难治性水肿，患者病情严重，住院超过1周，包括利尿剂之外药物的静脉治疗。
