In other instances a plastics elongated affixed to the tube is often used where the application of the pharmaceutical or veterinary product requires the tube canula to be brought almost into contact with the area to be treated and there is some danger or likelihood of damaging the affected area by metal contact.

除此之外，(在其他的情况下，这里译成除此之外更通顺一些)加长式塑料管口的软管主要应用于制药或是兽用产品中，某些药剂在使用中需要管口与患处直接接触，而金属管口对于感染部分可能产生危险或是破坏。

Careful attention should be paid to every steps of enterostomy operation in order to prevent the complications of stoma. These include the incision of skin, hypodermis, fascia and peritoneum, fixation of bowel around the stoma aperture, the size and shape of stoma, and the supportive tube in loop ostomy.

要求术者用心做好造口手术的每个细节，包括造口皮肤切口、皮下、筋膜、腹膜等的切开和造口肠管之间的缝合固定，造口的大小和形状，以及襻式造口所用的支撑管，以达到预防造口并发症的目的。

SEM result showed that the sample had uniform phase distribution and smooth surface at dried state as well as interpenetrate network structure at hydrogel state. It was seen from the swell ing behavior curves that groups T1, T2 and T3 swelled rapidly within 10-30 minutes, and formed elastic composite hydrogel pipes. In addition, the expanding ratio of inner and outer diameter of the tube was 20%-30% and 100%-120% with swell ing, respectively. The equil ibrium water content of the hydrogel pipes increased with increase of collagen composition. Three groups of samples were immerged in PBS solution contained 2 mg/mL lysozyme at 37 for 1 month, their nozzle cracked, their wall became thin and more transparent. And also, there was small floc deposited on the tube surface.

扫描电镜观察到液氮脆断的人工泪小管内部成分分布均匀，内外壁表面平整，冷冻干燥的人工泪小管断口呈凝胶态的互穿网络结构。3 组不同成分的人工泪小管在PBS 溶液中浸泡30 min 后均快速吸水溶胀，外径扩大100%～ 120%，内径扩大20%～ 30%，并且随胶原含量增高，溶胀速度增快，平衡溶胀率增大。3 组人工泪小管在37℃含2 mg/mL 溶菌酶的PBS 液中浸泡1 个月后，表面有部分细小絮状物，管口开裂，管壁变薄，透明度增加。

Retrospectively analyses 125 cases respiratory failure patients remedied by tracheal intubation in our hospital from 2001-04 to 2004-09. Comparing achievement ratio, time of detained airtube,incision of trachea ratio, extubate ratio, and sufferers' post-recovery condition of nasal trachea cannula under the guidance of fibrobronchoscope and oral trachea cannula under the guidance of laryngeal endoscope.

对我院2001年4月至2004年9月经气管插管救治的125例呼吸衰竭患者资料作回顾性分析，对纤支镜引导经鼻插管与经口喉镜明视插管各自成功率、留管时间、气管切开率、拔管率及患者的愈后情况进行比较。

Should the union nut and end connector on the "adjust" side of the valve be removed, this change negates the possibility that pressure on the other side could blow the internal components and fluid medium out of the open valve end to injure the service mechanic and/or surrounding equipment.

在拆卸阀门的可&调节&端口的管接螺母和端口连接件时，这种改进消除了另一个端口的压力将内部部件和流体介质从阀门开口端口处吹出导致维修技工伤害或破坏周围设备的可能性。

The process of sand absorption is:(1) the vibration head vibrates and losses the sand layer, and supply high pressure air into the sand absorption head;(2) the high pressure air generates negative pressure in the sand absorption pipe when it is discharged out from the sand absorption;(3) the sand absorption head and the vibration are shifted downwards and maintains the water flow straightly.

取砂土的过程为：(1)振动头振动松散砂土层，同时向吸砂头供入高压空气；(2)高压空气通过吸砂头从排砂管向上排出的过程中，在吸砂管内产生负压，吸砂管将管口处的水和砂土吸入到吸砂头内，在高压气流作用下，吸砂头内的砂、水和气混合而成的三相流通过排砂管排出到受砂船上；(3)在吸砂的过程中，适时地将吸砂头和振动头下移并保持钻孔套管中的水流畅通。
