Examinations of steady status and analysis of dynamic experiments have been conducted on Band-Tube evaporator and Parallel-Flow condenser using R134a refrigerant. The steady examination show that the model error was under the allowable error, The inlet mass and enthalpy disturb experiments indicate that the subsection model ,be good at reflecting the change of parameters of the heat exchanger, accord with the basic principle of thermodynamics theory and the actual work status.

在进行仿真试验时，以使用R134a作制冷剂的管带式蒸发器和平行流式冷凝器为对象，完成了稳态仿真计算、试验和动态仿真分析，稳态计算结果和试验数据对比表明，其误差在允许范围内；进口质量和焓值的扰动试验结果表明：本文所建的区段式换热器仿真模型，能很好的反映换热器性能参数的动态变化，与系统热动力学理论和冷凝器、蒸发器的实际工作过程基本一致。

Firstly, the establishment of model requires sophisticated neurointerventional techniques and costly interventional materials(sacculus, minikin circlip ring, endovascular electrocoagulation), it not only consumed time but also increased the resesrch expense ; Secondly, although the Massoud model is the first successful model that contain the nidus, but it is far from mimicking the high-flow fistulae frequently observed in a brain AVM; Thirdly, the rapid spontaneous thrombosis result in fistula occlusion in a short time;Fouthly, the model's natural course and the long–term patency of fistula are unclear;Currently the model is only used for the short-term research.

但Massoud模型目前存在以下主要缺点：第一，模型的建立需要复杂的神经介入技术和昂贵的介入材料(球囊、微弹簧圈、血管内电凝等)，操作费时，又大大增加了研究费用；第二，Massoud模型虽然首次具备了畸形血管团，但它远不是我们临床上常见的含有高流量动静脉瘘的脑AVM；第三，颈动静脉吻合口自发性血栓形成进而导致引流静脉闭塞的机率很高；第四，Massoud模型的长期自然过程和动静脉吻合口的长期通畅性尚不清楚，目前仅仅作为急性期模型。

The experimental results indicate that, over a ranger of tube side Reynolds number and Prandtl number (Re=4000~20000, Pr=6~7.5), the internal Nusselt number and friction factor of spiral-flat tube increased by 30%-150% and 20%-50% respectively compared with smooth tube at the same Re and Pr. The value of friction factor decreases with increasing the value of B/A as well as increasing that of S/de, and the same phenomena can also be observed for Nusselt number.

实验结果表明：管内Nu和f值均随均随B/A值和S/de值的增大而减小，但随B/A值的增加而减小得更快，B/A值对螺旋扁管管内传热与流阻性能影响更大；在相同Re和Pr下，螺旋扁管管内Nu数为光滑管的1.3～2.5倍；阻力系数f是光滑管的1.2～1.5倍。

Around 85 percent of smoke in a smoky room is so-called sidestream smoke, which is the smoke created between puffs taken on a cigarette.

烟雾辽绕的房间内，大约有85％的烟是所谓的「旁流烟」，也就是香菸在吞吐之间燃烧时产生的烟。

For a few seconds afterwards I have a fine spiritual glow… and maybe it would continue that way indefinitely – how can you tell?– if it weren't for the fact that there's a woman beside you and then the douche bag and the water running… all those little details that make you desperately selfconscious, desperately lonely. And for that one moment of freedom you have to listen to all that love crap… it drives me nuts sometimes… I want to kick them out immediately… I do now and then.

完事以后有几秒钟我觉得精神振奋……也许这种精神状态会无限期地持续下去-若不是身边有个女人，还有装灌洗器的袋子，水在哗哗流……这些微小的细节使得你心里清楚得要命，使你觉得十分孤独，而就在这完全解脱的一瞬间内你还得听那些谈论爱情的废话……有时这简直要叫我发疯……我不时发疯。

Firstly, the single-phase flow field of a typical NACA cascade was calculated and the predicted pressure coefficient has good agreement with the experimental data.

文中首先采用不同的壁面处理方法（标准壁面函数法和两层区域模型法）计算了一典型NACA叶栅内的单相流场，两种壁面处理方法得到的压力系数与实验数据符合很好，两层区域模型在前缘处的压力系数好于标准壁面函数法，与实验数据更接近。
