下导管

In severe cases use of a catheter is necessary to empty the bladder, often a painful experience.

在严重的情况下使用是必要的导管清空膀胱，往往是一个痛苦的经历。

High-pressure trunk-injection of iron fertilizer was reported to be effective to correct chlorosis, but the mechanism involved was unknown.

结果表明，铁肥树干强力高压注射，主要以二价铁(Fe2+)沿中央木质部的导管运输，大部分向下运输，使铁在根中大量贮存；向上运输较少，运输速度为每小时数百厘米，矫正缺铁失绿症的速度比根系输液慢，但由于根中贮存大量的铁，持效期较长。

Nursing care content includes:(1)Closely watching patient's WBC change during chemotherapy periods and applying leukogenic drugs for serious WBC fall patients.(2)Periodically sterilizing peripheral skin of opening of wound and outside catherter,and coving and changing sterile dressing for one time every two days or one time everyday when it is hot.(3)Irradiating wards with ultraviolet ray and sterilizing air everyday.(4)Helping patients to get up and do sports to strengthen organism's antiinfectionability.

护理内容包括：(1)在化疗期间密切监测病人白细胞的变化，对白细胞显著下降者应使用升白细胞的药物；(2)定期消毒处理创口周围皮肤和外露导管，更换覆盖无菌敷料，一般隔日1次，天气炎热，每日1次；(3)每日进行病室紫外线照射和空气消毒；(4)协助病人多下床运动，以增强机体抗感染能力。

从仪表板上拆下除霜器导管。

Methods: The electronic gastroscopy and MAXFORCE TTS water balloon catheter dilator were adopted to dilate esophageal stenosis in86 patients.

方法应用电子胃镜及水囊导管扩张器在直视下治疗食道狭窄86例。

The bigger top tension will cause the wellhead to be over-pulled and increase the probability of wellhead collapse. As the mean drifting of drilling vessel or platform increases, the wellhead displacement and bending moment nearly linear enlarges. The greater current velocity may result in wellhead instability because of its limited bearing moment capacity. Therefore the drifting control is very important to subsea wellhead stability. The wellhead stability may be improved by taking measures such as enhancing the conductor bending strength, controlling scour depth on seabed, getting geological data sampling of shallow formations.

算例分析表明，水下井口的横向偏移及弯矩随张力比和海流流速的增加而大幅增大，顶张力过大会引起井口稳定性变差；随着钻井船或平台漂移量的增加，井口的横向偏移和弯矩近似线性增加，控制好钻井船或平台的漂移非常重要；由于井口承受弯矩的能力有限，较大海流流速情况下可能造成井口失稳；提高导管抗弯强度、控制泥线处管柱冲刷、获取浅部地层的取样数据等措施可以增强井口稳定性。

It can accurately record the images of the soft tissue with different penetrability. Especially, it is able to catch small "sand-shaped" calcified focus which is of segment significance in the mammary gland duct. This technology, combined with directional piercing cytology inspection, can accurately determine the confinement of the breast lump, and detect all breast tubercles.

钼钯摄片能精细地记录下不同穿透能力的软组织留下的影像，特别是能捕捉到对乳腺导管内具有重要着段意义的微小泥沙样的钙化病灶，结合定位刺穿细胞学检查，则能高准确地确定乳房肿块位置的限制，能发现直径在一毫米的乳房结节。

Methods Tumors of parotid gland of48cases were partially dissected by using the superficial musculoaponeurotic system as an interposing flap,dissociating the branches of facial nerve and reserving the duct of parotid gland.

对48例腮腺肿瘤，采用自腮腺嚼肌筋膜下翻瓣，游离面神经分支，保留导管，部分切除腮腺组织。

PDA was often combined with all kinds of intracardial malformation ,preoperational diagnosis and interoperative exploration are extremely helpful for diagnosis . A strict control of indication and the improvement of CPB technique are significant to lower the death rate and postoperative complication . Suturing PDA through incision in pulmonary artery under CPB is the main treatment for PDA, using Foley catheter to block arterial canal flow helps to fully expose the operating field 、shorten CPB duration and lower the complications of lungs and brain .

各种心内畸形经常合并PDA，术前诊断及术中探查，意义重大；严格掌握手术指征和提高CPB技术，对降低手术死亡率及术后并发症具有重要意义；经肺动脉切口缝闭PDA是CPB下处理PDA的主要方法，术中应用 Foley导尿管阻断动脉导管血流，有利于术野显露、缩短CPB时间，可降低肺部、脑部并发症。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
