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

In terms of continuum mechanics and nonequilibrium irreversible thermodynamics theories, compressible Leonov constitutive model is derived to describe large recoverable elastic strain development in non-isothermal flow of compressible viscoelastic melts. It is tempting to specify the model and then compare it to basic rheological tests in the hope that such a model will yield a good description of the nonlinear viscoelasticity of polymer melts.

注射成型是聚合物的主要成型加工方法之一，成型过程中聚合物要经历熔体流动和固化等非等温、非平衡过程，由于聚合物的粘弹性，流动过程中建立的剪切应力、法向应力和大弹性形变在固化过程中不能完全松弛，在制品中形成残余应力和取向，对制品的机械和光学性能有着重要影响。

Gabor-ring is often used in texture feature extraction, but it is based on the assumption that texture is narrowband signal and can not applied to most actual textured images that have more than one center frequency in power spectrum. To overcome the limitation of existing method, an improved method is proposed. According to this method, Gabor filters are constructed in accordance with the spectrum feature vector of texture, and a relaxation parameter is used to determine the effect of difference filters so as to integrate the frequencies and phases into the process of extraction.

Gabor环（即在频率域成环形分布的Gabor滤波器组）常被用于提取图像纹理特征，但它是以"纹理是窄带信号"为基础的，实际的纹理图像并不能很好地满足"窄带信号"的假设，用一个中心频率来描述一种纹理对能量集中在多个频率点的纹理图像往往不能取得理想的效果，而根据频谱特征值向量构造Gabor环的改进方法，通过松弛因子的加入改变不同滤波器的作用强度，综合考虑了多频率多相位对纹理特征提取的影响。

First, for a given integer value of the objective function, the lower and upper bounds of the variables were determined by the optimum simplex tableau of the linear programming relaxation problem. Then the conditions on the bounds were added to the constraints as cuts to the associated objective function hyperplane. Finally, a branch procedure of the branch-and-bound algorithm was applied to finding a feasible solution on the objective function hyperplane.
