S where the threaded portion has an extruded rigid "canula" of small diameter. These are used where the areas of application of the product are specifically defined.

2在管口的螺纹部分有一个小直径的挤压硬管，如果产品的使用部位需要特别界定，则适用这种管口。

Type 1-1-1,2-2-1 and 2-2-2 account for 91 4%;The appearing rats of distal lingual canal are 24 7%;The appearing rats of double root canal orifices are as follows:Medial canal 78 3%,distalcanalIt don't ...

远中舌根的发生率为 2 4 。7%；双根管口率：近中根为 78.3%，远中根(不含远中舌根，下同)为 19.3%；双根管率：近中根为 88.3%，远中根为 2 3.3%；双根尖孔率：近中根为 5 6 。7%，远中根 8.3%，单根管口而有双根尖孔者，近中为 6 。7%，远中为 3.3%。结论下颌第一恒磨牙根管的类型复杂，充分了解其根管解剖对提高根管预备效果、减少根管遗漏有重要意义。

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。

The sound pressure fields at M=0, M=0.1 and M=0.2 are also given out. It is found that the constant pressure contours at the distances not too far from the duct end are caved-in backward due to the effect of flow. And it can be explained using Snell's law.

同时还给出了M=0、M=0.1和M=0.2管口辐射声场的声压分布，发现流动使离管口稍远处声压等值线向管口方向凹陷，并用Snell定律作了解释。

Which might fall through the tube opening into the dephlegmator header if not covered. The temporary installed steel sheet is to be removed after the steam distribution duct has been installed.

建议使用 1.5 mm 钢板覆盖管口处，以避免损伤并减少掉入逆流凝汽器联箱的焊渣等，如不覆盖，焊渣可能通过管口处掉入联箱。

METHODS:Fifty two permanent maxillary first molars,which were diagnosed as pulpitis and periapical periodontitis clini cally,were selected.The pulp chamber floors were examined and detected to locate the mesiolingual canals(MB2) by naked eyes and SOM respectively.

由于其近颊根通常有近中颊和近中舌(MB2 ) 2个根管，而其近中舌根管细小且根管口常较为隐蔽，因此，Weine认为上颌第一恒磨牙根管治疗失败的一个主要原因是治疗中遗漏了MB2根管。

"Typer" or "torpedo" nozzle tubes have no threaded portion at the nozzle area and require to be pierced with a pin before the product can be squeezed out.

4&锥型&(Typer怀疑是taper锥形管口，typer是打字机的意思，实在想不出应该怎么译)和&破坏式&(torpedo是鱼雷，攻击，破坏的意思，鱼雷式管口或是破坏式管口你自己再看看有没有更专业的译法吧)管口的软管没有螺纹部分，需要用大头针将其刺破，产品才能挤出来。

Compared with the diameter and the density of tubular opening, the mean percentage tubular opening area reflects the feature of the pulp cavity wall more comprehensively.

牙本质小管口的相对面积较单纯的牙本质小管口的直径和密度更能全面地反映不同部位髓腔壁的特征。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。

The factory affiliated to the Group primarily manufactures multiple-purpose pincers, baking kits, knives, scissors, kitchenware, gardening tools and beauty care kits as well as other hardware tools, the annual production value of which reaches US$ 30 million dollars.
