It is found that the fouling rate is lowered during subcooled fow boiling by carrying gas injection, and the influence of carrying gas injection on fouling of convective heat transfer is more obvious than that of subcooled flow boiling; morphology of CaCO〓 crystallization fouling exhibits self-similarity and the fractal dimensions of CaCO〓 crystallization fouling are determined from the gray scale distribution of the SEM images by box-dimension method. The value of the crystallization fouling surface fractal dimensions reveals the complexity of the surface, and can be used as an import parameter for the investigation of influence of carrying gas injection on scale formation.

实验发现：引入载气，过冷流动沸腾结垢速率降低，但引入载气对过冷流动沸腾结垢速率的影响要弱于对对流传热结垢速率的影响；CaCO〓结晶垢具有统计自相似性，即分形特征；用盒子维法测定了CaCO〓结晶垢的分维值，分维值的大小反映了换热面上生成的结晶垢表面复杂程度，可用于描述引入载气对污垢的形成作用。

Behaviour ecology, physio-ecology and community ecology of vines in the evergreen broad-leaved forest of Tiantong National Forest Park, Zhejiang Province, China, were studied and rich first-hand data were collected in this project.Some vines with different climbing motheds were much different in leaf anatomy, ecophysiology, growth rhythm and behavior, and another vines with same climbing methods showed similar adaptation to habitat, on which their distribution in a forest depended. The concept of climbing unit consisted of internode, leaves and tendrils or other climbing organs on it was put forth, and the method to calculate and value the climbing capaity of a vine was set up. In the meantime,experimental ecology of a twining vine Humulus scandens was carried out.

本项目以浙江天童常绿阔叶林为基地，从行为生态、生理生态和群落生态学等角度较系统深入地研究了常绿阔叶林藤本植物的生态适应特征，取得了丰富的第一手资料，结果表明不同攀援类型的藤本在形态结构、生理生态、生长和攀援行为上表现出明显的差异，而同一攀援类型的藤本表现出较大的趋同适应的特征，但也存在着差异，这些特征或差异决定了它们在群落中分布的层次和与支持木之间的作用方式；提出了攀援单位的概念，初步建立了攀援能力的测定和评估方法。

The clinical characters of oligodontia concluded from this study are following:(1) There is significant difference that more teeth absent and more existent teeth anomalies in patients of oligodontia/S group than in patients of oligodontia/I group, and the peg-shaped upper lateral incisor is the most frequently affected teeth with shape anomaly.(2) Both of the two groups have no significant differences in number of teeth missing between maxilla and mandible as well as that between left and right side.(3) The distribution of teeth missing is bilateral symmetry in both groups, but the frequency of teeth lost are different: excluding the third molar, in oligodontia/I group, the lower second premolar is the most frequently congenitally missing tooth followed by the upper lateral incisor, while in oligodontia/S group, the most frequently missing teeth are mandibular canine and maxillary lateral incisor. Nevertheless, the first molars are the most stable teeth in both groups.(4) In oligodonita/I group, the mean mesiodistal dimensions of all type of existent teeth are significantly smaller than normal value. It is implied that oligodontia is not an isolated phenomenon, but is related to a complex of other dental changes.

对于口腔多个恒牙先天缺失的临床特点有以下初步结论：(1)综合征型先天缺牙患者较单纯型先天缺牙患者恒牙缺失数目更多，平均分别为23.9个和14.9个，且现存牙齿有更多的形态异常，分别为7／10例（70％）和6／22例（27.3％），其中最常见的是上颌侧切牙畸形；(2)两种类型的多个恒牙先天缺失患者的缺牙数目在上下颌及左右侧之间均无差别；(3)两种类型的多个恒牙先天缺失患者在缺失牙位上均呈对称分布，但在具体牙位上有所差异：不计第三磨牙，单纯型先天缺牙最常缺失的牙位是下颌第二双尖牙、其次为上颌侧切牙；而综合征型先天缺牙最常缺失的牙位是下颌尖牙和上颌侧切牙；无论何种情况，第一磨牙均为牙列中最稳定的牙齿；(4)在单纯型先天缺牙患者中，现存恒牙的牙冠宽度较国人正常值偏小，差异显著，提示牙齿形态与多个牙先天缺失有一定相关性。
