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。

Output voltage changes due to changes in internal temperature must be taken into account separately.

输出电压的变化，由于内部温度的变化，必须考虑到分开。

The results showed that the diurnal changes of photosynthesis of S. chinensis in tile overstory took on "double-peak" curve with remarkable midday depression. The midday depression was mainly due to non-stomata1 limitations. On the contrary, the diurnal changes of photosynthesis of S. chinensis in the understory took on "one-peak" curve with low Pn. The maximal Pn was only half of that of S. chinensis in the overstory. The correlation analysis showed that the limiting factor for this low Pn might be light intensity (p=0.001). Compared with its accompanying plants, S. chinensis was in a disadvantaged status in the community with low photosynthetic capacity, water use efficiency, and the ratio of photosynthetic rate to respiration rate.

结果表明：夏蜡梅冠层的光合速率日进程呈"双峰"曲线，有明显的"午休"现象，经分析其"午休"的原因主要是由非气孔因素引起的；林下夏蜡梅则表现为"单峰"曲线，净光合速率较低，最大净光合速率不及冠层的1/2，相关分析结果表明其最重要的影响因子是光合有效辐射(p=0.001)；与其它伴生植物相比，夏蜡梅的日均光合速率、最大光合速率、水分利用效率和光合速率／呼吸速率都明显偏低，在群落竞争中处于不利地位。

The research of cytology shows that there are dramatically morphological and structure changes in the leaf: the cells of mesophyll array loosely and parenchyma cells reduced, cambium becomes thinner and degree of xylem becomes more serious, the content of chlorophyll dropped; the changes of conducting tissue and stoma structure affect transport and allocation of water and nutrient, hinder leaf growth and disturb regular metabolism of leaf, at last lead to wilt, rot and become crisp papyraceous.

细胞学研究表明，病叶组织的叶肉细胞排列疏松，薄壁细胞层次减少，形成层变薄，木质化程度加深，叶绿体减少；在病叶中由于疏导组织和气孔的结构发生变化，影响养分和水分在植株体内的运输和分配，干扰叶片的正常代谢，抑制叶片的生长发育，最终导致叶片失水萎缩、干枯，变为焦脆的干纸状。

Finally, according to the characters that the inner and outer edge of double-layer eyelid are approximate parallel and the gray distribution changes sharply on the edge of inner eyelid, take the fitting curve acquired in first eyelid location as a template, and shift it down parallel to detect the position where gray value changes abruptly.

最后，根据双层眼睑的内外层边缘近似平行、而且在内层眼睑边缘处出现灰度跳变这一特点，以第一次定位所得拟合曲线为模版，平行下移搜索灰度跳变位置，完成对双层眼睑的二次定位。
