Objective: To study the distribution and dilation of intracranial venous reflux pathway after bilateral radical neck dissection. 目的:研究双侧根治性颈淋巴清扫术后颅内静脉血液回流通道的分布和开放情况。
To investigate the influence of Marangoni effect on liquid flow and its distribution as well as separation efficiency of structured packing, binary distillation experiments were carried out at total reflux using six typical systems for ceramic corrugated sheet and stainless steel gauze structured packing. 选用6种代表性物系对陶瓷板波纹和不锈钢丝网规整填料进行全回流精馏实验,考察Marangoni效应对规整填料液体流动分布及传质的影响。
The results show that the angle of cross jets and density ratios have important influences on the velocity distribution on radial, the length of reflux zone and the quantity of reflux. 文中分别研究了射流交叉角度和密度比对径向速度分布、回流区长度、回流量的影响。
Based on tests the distribution, shape and size of reflux area, reflux rate and its effects are analysed in this paper. 本文在实验的基础上对回流区的分布、形状、大小、回流率及其作用进行了分析。
