In order to control the depth of the acupuncture, this research makes use of the photo interrupter to detect parallel grating swept and combine the depth gauge organization to measure the acupuncture profundity.

为了掌控针灸针进针深度，本研究所设计之针灸针深度计乃使用光遮断器感测元件侦测所扫过之平行光栅数，并结合深度计机构之设计来量测其针灸针进针之深度。

However, two kinds of problems exist in the use of the machines. One is that fibers left on doffer can＇t be reused, which may damage needles when they are accumulated for a long time, and the other is that fiber fed by carding mechanism is not in accordance with that is needed, because of the unevenness of sliver, which will finally result in the unevenness of fabric density.

目前国内外生产的人造毛皮机在使用过程中普遍存在着两个问题：一是道夫上未被织针钩取的纤维不能回收利用，时间久了积聚起来对织针和道夫针布造成损伤，影响生产；二是由于存在着喂入毛条重量不匀的问题，使织针和道夫针布喂毛机构喂入的毛纤维量不准确，从而造成织物的密度不均匀。

Technical progress and development tendency of cylider, doffer plate, taker-in clothing and fixed division-carding parts, as well as the general principles for carding cloth selection, are described. Emphatically, the configuration of clothing for chemical fibre and technology and clothing adjustment of difficult-spinning fibre are given.

We describethe efficacy and adverse events associated with a modified epiduralneedle versus a conventional Tuohy needle for CSE. One-hundredparturients requesting labor analgesia were randomizedinto 2 groups: 50—ES 18-gauge modified epidural needlewith 27-gauge Pencan atraumatic spinal needle, 50—conventional18-gauge Tuohy needle with 27-gauge Gertie Marx atraumatic spinalneedle.

我们比较了改良的硬膜外针和传统的 Tuohy 针用於 CSE 的效果和不良事件。100名临产要求行无痛分娩的产妇随机分为2组：50名用 ES 18号改良硬膜外穿刺针复合27号 Pencan 防损伤腰麻针，50名用传统的18号 Tuohy 针复合27号 Gertie Marx 防损伤腰麻针。

The invention also relates to a nozzle body (31) comprising a nozzle outlet which is disposed on the combustion chamber side end thereof, a nozzle needle (33) which is arranged in an axially displaceable manner and/or which can is actuated in a longitudinal recess (32) of the nozzle body (31); a throttle disk (25) which is arranged between the nozzle body (31) and the control valve (20) and which is closed on the rear end (oriented away from the nozzle outlet) of the longitudinal recess (32). Said throttle disk forms an opening stop for the nozzle needle (33) which co-operates with the rear front surface (orientated away from the nozzle outlet) of the nozzle needle (33) and defines the opening stroke of the nozzle needle (33), and a control chamber (45) formed between the rear nozzle needle front surface and the throttle disk (25), said control chamber being hydraulically connected to a pressure connection (29) which is used to supply fuel.

还设置了：一个喷嘴体(31)，在该喷嘴体的燃烧室侧的端部上构成一个喷嘴出口；一个喷嘴针(33)，该喷嘴针在轴向上可运动或可操作地安置在该喷嘴体(31)的一个纵向开口(32)中；一个封闭该纵向开口(32)的后面的端部的、安置在喷嘴体(31)与控制阀(20)之间的节流盘(25)，该节流盘构成用于该喷嘴针(33)的一个打开止挡，在此与该喷嘴针(33)的后面的端面协同作用并由此限定该喷嘴针(33)的打开行程的边界；和一个在该后面的喷嘴针端面与该节流盘(25)之间构成的控制室(45)，该控制室与一个用于燃料输入的压力接口(29)处于液压连接中。

Needle taking place is commonly used the rescue that changes cure and danger to weigh a patient at patient of children, tumour, in infusion, because secure not firm outside can bringing about syringe needle slippery haemorrhage to be in charge of, cause local strut, aching, serious person can send infiltration of the certain pharmaceuticals that change cure to cause subcutaneous tissue hypodermically necrotic or the liquid cannot be defeated in time note and illness of incur loss through delay, new puncture increases the patient's anguish not only, also increased economic burden to also can be affected at the same time to the patient nurse working quality, the course relapses clinical experiment, my division adopts vein to accept the annular and fixed method of buy needle, obtained better result, introduce as follows now. 1 method is taken fixed stick (needle taking place is deployed) together, the disinfection that wide 10cm controls wraps cloth, two paragraphs of end are seamed on after sticking glue to buckle vein to leave buy needle puncture to succeed, convention is secured with adhesive plaster, next the ground degree of tightness will take stalk of handle of buy pinhead, needle, needle to be in firmly aptly fixed and fixed stick , next annular in blood-vessel twine stick on stick buckle. 2 experience apply this method to secure vein to left buy needle method to reduce the patient's anguish, reduced cost, provided mobile space for the patient, also avoid heparin cap prolapse, still facilitate observation puncture is nodded, do not affect hematic use, gauze pad can alleviate heparin cap is oppressive and unwell, reduce infusion pollution.

概要： 留置针常用于小儿、肿瘤患者化疗及危重患者的抢救，在输液中，由于固定不牢可导致针头滑出血管外，引起局部肿胀，疼痛，严重者可致某些化疗药物渗入皮下造成皮下组织坏死或液体不能及时输注而延误病情，重新穿刺不仅增加病人的痛苦，也给病人增加了经济负担同时也会影响护理工作质量，经过反复临床实验，我科采取静脉留置针的环形固定方法，取得了较好的效果，现介绍如下。1方法取固定贴一块，宽10cm左右的消毒包布，两段端缝上粘胶扣静脉留置针穿刺成功后，常规用胶布固定，然后将根据松紧适宜将留置针头、针柄、针梗处牢牢固定固定贴，然后在血管中环形缠绕粘上粘扣。2心得应用此方法固定静脉留置针方法减少了患者的痛苦，降低了费用，为患者提供了活动的空间，也避免肝素帽脱垂，还便于观察穿刺点，不影响血运，纱布衬垫可缓解肝素帽压迫不适，减少输液污染。

Based on these, this study was to determine the relationship between standing vegetation and soil seed bank. The main results are as follows: 1 Effects of grazing on plant communities The grazing successions were Stipa klemenzii → Salsola collina + Stipa klemenzii → Salsola collina community in the desert steppe; Stipa grandis or Leymus chinensis → Cleistogenes squarrosa + Stipa krylovii or Stipa grandis → Potentilla acaulis + Cleistogenes squarrosa community in the typical steppes and Leymus chinensis + forbs →Leymus chinensis + Stipa baicalensis community in the meadow steppe.

主要结论如下： 1放牧对植物群落的影响荒漠草原的放牧演替规律为小针茅群落→猪毛菜+小针茅群落→猪毛菜群落；典型草原为羊草或大针茅群落→糙隐子草+大针茅群落或克氏针茅群落→星毛委陵菜+糙隐子草群落；草甸草原为羊草杂类草群落→羊草+贝加尔针茅群落，这是不同物种对牧压的不同适应结果造成的。

A: (1) to thread a needle position and the location to the end of the needle for accurate;(2) to thread a needle, thread a height that you want to play your cards right-to-lead down to needle can be hook line hook the hyriopsis accurate;(3) to thread a needle and the top of the line hyriopsis-Kwan, the distance to 0.7-1 ~ guests'glasses;(4) homulus line-pin recesses to smooth, hook-billed is not too large or too small, so as not to overly homulus line, break, and so on.

答：(1)穿线针位置与底针位置要对准确；(2)穿线针高度要得当，穿线针引线下降时以能被钩线三角准确钩住为准；(3)穿线针与钧线三角顶端工作时的距离一般以0.7—1mm为宜；(4)钩线针的凹槽要光滑，钩嘴不可过大或过小，以免造成不钩线、断线等故障。

Lock Stitch - 1 Commonly referred to as a lock-down or tack-down stitch, a lock stitch is formed by three or four consecutive stitches of at least a 1mm movement.
