In flow visualization experiment, it is found that flow rate of safety injection has major effect on flow regime in downcomer.

通过流动可视化实验，得到了安注流速，下降环腔流速以及含气率对环腔内流动形态的影响。

The mixture zone of safety flow and downcomer flow is limited at a narrow stripe in downcomer when flow rate of safety injection is low.

下降环腔流速使低安注流速时的安注影响的范围局限于下降环腔下游的细长区域。

The flow regime in downcomer can be divided into two kinds: cross flow injection and impingement. Cross flow injection only takes place under low injection flow rate in dowcomer flow. The investigation on flow regime and heat transfer in RPV under PTS is for the first time in China.

在国内本实验是第一个研究下降环腔内的流动与传热，在国际上，象这样同时进行了流动可视化，常温常压下传热和高温高压下传热的实验也不多，特别是针对下降环腔内对流换热系数的研究，在公开文献中还没有相类似的实验。

The results of the experiment agree with the theory.TEM00 mode output in which the ellipticity is 0.98 and M2 is 1.01 was obtained.

利用实验结果指导腔调节，可使泵浦光轴线与几何腔轴精确重合，获得了椭圆率为0.98、M2因子为1.01的基模输出。

The direct signs of Pulmonary embolism were luminal constriction,emphraxis,branched decreased,intraluminal lowD filling defect of blood vessel;while the indirect signs,formation of pulmonary infarction focus,pleural effusion,pneumonia,atelectasis,pulmonary dilatation and hydropericardium,etc.

肺栓塞的直接征象为管腔狭窄、阻塞、分支减少及血管腔内的低密度充盈缺损，间接征象为肺梗死灶形成、胸腔积液、肺炎、肺不张、肺动脉增宽、心包积液等。

Pathologic results: The bronchioles showed obvious chronic inflammatory process of bronchioles including thickened wall, narrowed lumen, goblet cell proliferation, emphraxis in bronchiole, interstitial fibrosis and developed emphysema in stable model of COPD.

病理结果示：稳定模型组各级支气管慢性炎症明显，管壁增厚、管腔狭窄、杯状细胞增生，细支气管管腔闭塞较多，肺间质纤维化明显，肺气肿形成，小动脉管壁增厚明显。

Material and MethodsRA Rabbit Model group: 15 early RA rabbits of the same weight and variety Control group:10 normal rabbits of the same weight and varietyMethods of making RA rabbit model:elect 15 normal rabbits of the same weight and variety, dissolve Ovalbumin in 0.9% sodium chloride solution, to make the solution of 20mg/ml concengtration, blend the same quantity of complete Freund′s Adjuvant equably ,inject the mixed solution into endermic tissue of the rabbit′s scapular section, making the rabbits allergic, inject 1 ml of the mixed solution to one rabbit every time, inject 1 ml of the mixed solution in 5 different places of the rabbit′s scapular section, inject the rabbit one time every week,inject 3 weeks continuously,it turned out to be that the rabbits will be allergic, inject Ovalbumin blent with the 0.9% sodium chloride solution into the knee joint cavity of the rabbits in the fourth week, 5 mg Ovalbumin every knee joint cavity,two knees of every rabbit of the 15 rabbits are both injected,the arthrosis diameter and the exterior temperature of the knees will be added obviously in 24 hours,and they will drop gradually,at the time of the 14th or 21th day, the arthrosis diameter and the exterior temperature of the knees will get to the balance time,the incidence rate of RA is 100%.after the RA model succeeds,it is the early time of RA from the first week to the fourth week,after the fourth week,it is the late time of RA, the cartilage of the femoral condyle and the subchondral bone cortices will be changed unrecoverily.

资料与方法RA模型组：早期RA家兔模型15只，品种及体重接近。对照组：正常家兔10只，品种及体重接近。RA家兔模型制作方法：选取15只成年家兔，体重、品种接近，将卵蛋白溶解于生理盐水，配成浓度为20mg/ml的溶液，与等量完全弗氏佐剂混匀，注入家兔肩胛区皮下致敏，每只家兔每次注射1ml，于肩胛区5个不同区域注射，每周一次，连续注射3周而致敏，第4周向膝关节腔注射卵蛋白生理盐水溶液，每只关节腔注射5mg卵蛋白，15只家兔膝关节全部注射，24h内此关节直径和表面温度大幅度上升，以后缓慢下降，至14～21d达到平台期，发病率达100%。造模成功后第1～4周为早期改变，第4周以后出现不可逆的关节软骨及骨破坏。采用高频超声对RA模型组与对照组的膝关节髌上囊液体厚度、滑膜及股骨髁软骨厚度及软骨下骨皮质的回声情况进行对比观察。结果RA组模型组膝关节髌上囊积液及滑膜的厚度明显厚于对照组，其股骨髁软骨的厚度与对照组相比无明显差异，其软骨下骨皮质与对照组相比无明显改变。

Methods: The bilateral superior buccal branches of facial nerve were exposed and transected, a nerve growth chamber were created by suturing the epineurium and silicone chamber under microscope .The chambers of experimental sides were injected with HGF/normal saline and that of the control sides with normal saline of same amount (10μL ),the regenerated nerves in the chambers were dissected and postoperative evaluation were performed byelectrophyiological testing , histopathologic, morphological studies under gross observation, light microscope at 1,2,4 weeks after operation, respectively.

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
