查询词典 ventilating duct

If it is mainly extrahepatic biliary diffuse stenosis, it will gradually expand upward and downward along bile duct by Bakes biliary duct dilater after the bile duct is cut in surgery ( Including the sphincter of Oddi expansion,the dilatation should be gradual and slow. Too much strength will result in biliary rupture with vascular hemorrhage). T-tube is then placed to support drainage.

1.2、尖牙根尖与前鼻底(前缘后方2-6mm区域)最小距离均值为：8.12mm，6.21mm，因此，当侧切牙根尖距前鼻底过近时，可在梨状孔侧下方斜向植入长度为4-6mm和4mm的种植体。

Dilatation of the bile duct supporting drainage : Due to a longer section of the bile duct stenosis and unremovable lesion part, biel duct tube or U-shaped tube drainage could be employed.

胆管扩张支撑引流术：对于较长节段胆管狭窄、又不能切除病变部位者，可行胆管内置管支撑或 U 形管引流。

Results:Four cases occured in 24h postoperatively,3 cases among them for injury of bile duct outside liver,the other one for the ductus cysticus stump's clip exfoliation.8 cases occured after LC in 48 hours,because of leakage of cholangiole,injury of aberrant duct or heat injury of common bile duct.

结果：12例胆漏中4例在术后24h内发觉，其中3例为肝外胆道损伤，1例为胆囊管残端钛夹零落；8例在术后48h以后发觉，其原因为胆囊床毛细胆管渗漏、迷走胆管损伤和胆分管热损伤。

II: total plate combination duct: duct the overall processing portfolio, including the matching shaped duct.

二：共板组合风管：风管整体加工组合，包括配套异型风管。

本实用新型涉及一种旋耕施肥机，属于农业机械，它由旋耕机加装排肥机构及其传动装置而成；其排肥机构的肥箱和排肥管中分别装有水平绞龙和垂直绞龙，联接肥箱和排肥管的齿轮箱，既是传递动力的纽带，又是排肥的通道可施用各种粉状和颗粒状化肥该机结构简单，排肥可靠，且充分利用了现有机具

Through an analysis on mud-clogging mechanism of suction nozzles on wet type sweeper, a concept is suggested, that water ratio in dust nearing the wall of suction nozzle duct should be decreased so the mud stickiness can be controlled under a critical value and not sticking to the duct wall whereas water ratio in central dust passage of the duct is properly increased to satisfy effective dust absorbing. On the basis of the concept, a water spraying device is designed with improvement for suction nozzles. In the device, the water hole numbers, diameters and distribution along the nozzle circumference as well as initial direction of water spraying are all determined according to concrete suction nozzle structures.

通过对湿扫型道路清扫车的吸嘴易被泥土堵塞的机理分析，提出降低吸嘴流道近壁的尘土的含水率，控制泥块的黏性处于临界黏性以下，使泥块不黏附于流道壁面；而将吸嘴流道中心部位的尘土的含水率适当加大，以满足有效压尘的解决思路，并根据这种思路改进设计了一种吸嘴喷水装置，按不同吸嘴的具体结构确定孔数、孔径、孔沿圆周的分布规律和喷水的初始方向等要素。
