[英]['ʌltrə'ʃɔ:tweiv] [美][,ʌltrə'ʃɔrtwev]
股静脉瘀滞
3) stagnation
[英][stæg'neiʃən] [美][stæg'neʃən]
停滞
1.
Aiming at the above,the following strategy is suggested: adding the tracking and replacing mechanism to every searching node;counting the stagnation times of a node at a certain station in its searching route;if the times oversteps the allowable value,a new node randomly arises in the solution space to replace the stagnating one for improving the searching efficiency.
针对简单小世界算法在优化复杂函数时出现的停滞现象,提出对搜索进行跟踪、对停滞节点进行更替的策略。
2.
Aiming at the stagnation exists in the cooperative particle swarm optimization,presents a new kind of the cooperative particle swarm optimization algorithm based on particle s spatial extension.
针对协同微粒群优化存在的停滞现象,提出了一种新的基于粒子空间扩展的协同微粒群优化算法。
3.
But conventional differential evolution algorithm has a problem of stagnation that can stop the algorithm convergence.
但常规的差分进化算法存在停滞现象,容易使算法收敛停止,鉴于此本文提出一种改进的差分进化算法,对算法提出另一个终止条件并且重新产生初始个体,对种群大小N,变异率F,交叉率CR其中的也可作调整,在计算过程中引入精英策略,既防止了停滞现象也加快了收敛速率并使算法能收敛到全局最优。
4) standstill

经皮经颈静脉肝内门体静脉内支架分流术
介入放射学技术。也称经皮经颈静脉肝内门体静脉分流术(TIPS)，1969年最初由Rosch等首先报道。经颈静脉送入导丝，于门-腔静脉间经肝实质建立通道，并放入支架以形成永久性分流径路的治疗方式，以降低门脉压力，治疗顽固性的食管胃底静脉曲张出血及顽固性的腹水。该技术除常规导丝、导管、球囊扩张导管等外，需向建立的分流通道内置入支架，常用的有Z-型支架、Wallstent支架、Strecker支架等。
