组成图

To display animations with raster systems, animated objects (which may consist of graphical primitives such as lines, polygons, and so on) must be scan-converted into their pixmap in the frame buffer.

动画显示为了在光栅系统中显示动画，必须将运动物体(由如线，多边形这样的图元组成)经扫描转换变为可在帧缓存放的位图。

A Halin graph is a planar graph consisting of a tree with no vertex of degree two and a cycly connecting the leaves of the tree. We write .

Halin图是一个在平面上由内部点度数大於2的树及连接树的叶子的圈所组成的平面图，我们将Halin图用来表示。

During the Voronoi tessellation on a planar point set composed of massive points, a technical scheme of dynamic data-exchange between hard disk data file and internal memory structural array designed so, that the limitation of computer internal memory storage need not be considered and the construction of massive Voronoi cells as many as hundreds thousant in number was effectively implemented.

在对"海量"点组成的平面点集进行Voronoi划分时，设计"硬盘数据文件－内存结构体数组"之间动态的数据交互方案，避开计算机内存的限制，有效实现了数十万Voronoi晶胞集合体的构造，存储Voronoi图几何信息的数据最后以文本文件的形式输出，方便Voronoi图在工程实际中的应用与二次开发。

By systemic researching and simulating experiment, the text gains such results as follows,1. On the base of sufficiency research on the oil-gas hydrocarbon systemic chemistry composing and the physical chemistry characters, we traverse the mechanism of the paraffin's deposition. Then we consider that paraffin deposition is a complex process ofphysical chemistry, which includes more than one single mechanism.2. Traversing and comparing the literature in detail on different factors that has effect on paraffin deposition, the available experimental methods on paraffin deposition, prevention of paraffin deposition, and removing of the deposited paraffin on the spot.3. Ameliorated the laser equipment of solid particle inspecting system and the corresponding test methods. Determine WCT of dead oil and live oil from KS101 well under different pressure with this system. The result implies that dead oil has opposite regulation on paraffin deposition temperature to live oil.4. A vapor-liquid-solid envelop is drawn by superposition regular vapor-liquid envelop and WCT curve thereby explained that the departure and quick raising of the curve in the low temperature zone is caused by the appearance of paraffin in solid phase.5. Estimation is made to determine the depth of paraffin deposition in the well.

通过系统的研究和实验模拟，本文取得了以下研究成果：(1)在充分调研油气烃类体系的化学组成及其物理化学特征的基础上，详细研究了石蜡沉降的机理，认为石蜡沉积是一个复杂的物理化学过程，是多种机理共同作用的结果；(2)深入调研并综合阐述了影响石蜡固相沉积的各种主要因素，对目前国内外常用的有机固相沉积实验研究方法和现场清防蜡措施也做出详尽的描述，并加以对比评价；(3)改进了油气藏开发重点实验室自行研制组装的高温高压下测定固相沉积的激光装置和测试方法，并用该套设备测定出柯深101井的井口脱气油样和凝析气平衡油样不同压力下的析蜡点，实验结果表明，脱气油和平衡油析蜡规律相反；(4)将常规气-液两相相图和析蜡曲线叠加得到了气—液—固三相相图，从而解释了气-液两相等液量线在低温区域偏离正常并快速上翘是由于体系有石蜡固相出现；(5)利用实验测试的析蜡温度预测析蜡位置，表明只有在距井口465m油管以上会有蜡析出。

The results were as follows:(1) Seeds of 80 species or subspecies could be classified into two groups. Group Ⅰ included the seeds of Gramineae, Cyperaceae, Polygonaceae and Amaranthaceae, and Group Ⅱ included the seeds of Compositae, Euphorbiaceae, Brassicaceae and Umbelliferae.(2) Only FTIRs of the seeds of Brassicaceae were clustered together in the dendrogram,while those of the other families all appeared farraginous.(3) Among FTIRs of the 11 groups of the congeneric species,8 groups were clustered with other genus species, and 6 out of 7 groups of conspecific seeds appeared farraginous in the dendrogram.

结果表明：(1)80种草本植物的种子可以分成两类，第1类由禾本科、莎草科、蓼科和苋科植物的种子组成；第2类由菊科、大戟科、十字花科和伞形科植物的种子组成；(2)聚类图上，只有十字花科植物的种子能较好地与其他科的相区别；(3)在11组同属不同种植物中，有8组植物与亲缘关系不同的其他属的植物混在一起；在7组同种不同亚种或品种植物中，仅有1组植物被聚合在一起。

The phase diagrams of PEG/phosphate aqueous two-phase systems and the partition properties of BSA in the systems The PEG/phosphate aqueous two-phase system was regarded as the research object, the contents of phosphate and the polyethylene glycol in the system were measured by weighting and freeze-drying method respectively. Two diagrams were successfully drawn, and the characteristics such as binodal curves, tie lines and lever rule of the phase diagrams of the aqueous two-phase systems were described, as well as the achieved phase diagrams were qualitative analyzed with thermodynamics.
