Based on the analysis of the fluid flow in the downcomer of an airlift internal loop bioreactor , a turbulent two-fluid model for airlift internal loop was proposed.

在对气升式内环流生物反应器内部流动分析基础上，全面考虑反应器下降管中气泡的并聚破碎、气液两相间相互作用和滑移等，建立了能描述反应器下降管中复杂流动的CFD数学模型。

It was found that the flow pattern in an airlift reactor with net draft tube was similar to that in bubble columns instead of traditional airlift reactor.

实验结果得知，网状内管气举式反应器的液体流动行为较倾向气泡床，而偏离传统实壁管气举式反应器。因此，其可视为一种改良式之气泡床。

ABSTRACT Objective To discuss the importance of the study of conformation and variation of extrahepatic bile duct before gallbladder operationMethods The images of 100 cases having normal structure of gallbladder and extrahepatic bile duct were studied;the conformations and confluence sites were analyzedResults Among the 100 cases,97 cases had clear images of extrahepatic bile duct (97%),3 cases with large amount of air bulbs in bile duct because of the laxation of the lower common bile duct still had clear images of the general conformation of extrahepatic bile duct,87 cases had clear images of gallbladder and cystic duct (87%),13 cases (13%) had partial images of gallbladder or cystic ductConclusions ERCP can clearly show out the conformation and variation of extrahepatic bile duct and cystic duct and it is of important value before gallbladder operation

目的 通过对100例胆囊及肝外胆管正常结构尚存在的患者ERCP图像资料进行归纳和分析，探讨胆囊手术术前了解肝外胆道系统形态及变异的重要性。方法选出100例胆囊及肝外胆管正常结构尚存在的患者图像，对其形态、汇合位置进行分析。结果 100例患者图像中肝外胆管显示清晰者97例(97%)，3例因胆总管下端开口松弛导致大量气泡进入胆道，但肝外胆管大体形态显示尚清晰，胆囊及胆囊管显示清晰者87例(87%)，13例(13%)仅部分显示胆囊或胆囊管。结论 ERCP可以清晰显示肝外胆管及胆囊管的形态及变异情况，对于胆囊手术术前了解肝外胆道系统形态及变异有重要价值。 ERCP；胆囊管；肝外胆管

The flow field around Taylor bubbles rising through stagnant liquids in vertical tubes is considered as potential flow, and the first order approximation of the control equation of gas-liquid interface and the rising velocity of Taylor bubbles are obtained.

应用势流理论分析了垂直管滞止液体中Taylor气泡周围的流场，得到了气液界面的控制方程和Taylor气泡上升速度的一阶近似结果。

Results indicated that faiure below surface was alveolate and pressure of inner concave of the below was increased.

结果表明，失效弯管内表面呈蜂窝状结构；由于直管与弯管的管径差异，使弯管内壁凹面压力增大而导致气泡破裂造成气蚀条件；同时在弯管凸面沉积了结瘤物。

This paper mainly discussed about the research on microbubbles generation by metal microporous tube,it is a new method of bubble formation.

本文主要研究了用金属微孔管制造微气泡，这是一种比较新颖的气泡制造方法。

Making microbubbles by metal microporous tube is a new method.

用金属微孔管制造微气泡是一种比较新颖的气泡制造方法。

The effect of a horizontal immersed tube on the bubbles in a fluidized bed is not the same as that of a vertical tube or plate.

气泡在水平管的底部形成和聚集，由于水平管对上升气泡的阻碍作用，气泡的上升速度沿管表面变化很大。

Two models were developed, one for calculating the leakage rate of water from heat transfer tubes due to one broken double ended guillotine tube in the steam generator of LMFBR using the one dimensional method of characteristics, and anotherone for temperature, adiabatic spherical to columnar hydrogen bubble growth model in large sodium water reaction.

采用一维特征线方法建立了快堆蒸汽发生器单管发生双端断裂情况下，水从破裂传热管流出的泄漏率计算模型和钠水反应气泡从球状到柱状的变温绝热生长模型。沸腾是钠冷快堆安全分析工作中必须要考虑的一个问题，而堵流是众多导致发生沸腾原因中十分重要的一个。

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.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
