管口的

Authors believe that this change in dentin is one of mechanisms for desensitization mainly.

电镜所见，提示牙本质表面的变化和管口的封闭是牙本质过敏症脱敏的主要机理之一。

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。

"Radiologically guided insertion of the Entristar skin-level gastrostomy tube is a safe procedure in patients with ALS that allows the creation of a permanent feeding gastrostomy without the need for sedation or endoscopy," the authors write."The importance of a single-step procedure in patients with a terminal disease in whom quality of life needs to be optimized and hospital stay minimized must be emphasized.... The major technical problem with extending the service to other patient groups remains the tube length, which may be a more substantial problem over the longer term."

由於是以放射线的步骤作为插管时的引导，因此Entristar的皮层胃造口术管对於ALS患者是安全的，同时可以允许胃造口术管作为长久性的餵食装置，而不需要进行镇静剂处理或内视镜检视；研究人员Shaw指出，这种单一步骤的程序对於重病患者而言，可以提升患者的生活品质，减少住院的时间，这是必须强调的重点；就技术上而言，在将此技术延伸用到其他组的患者身上时，主要的问题就在於进食管的长度；而就长期观点来看，管子长度也是一个主要的问题。

Moreover, since the strain energy of zigzag tubes is larger than that of the armchair tubes with the same semidiameter, the ends of the armchair tubes are easier to be closed than those of the zigzag ones. And the closed structures of the zigzag tubes have a lot of defects, even at 3000 K, there will be few carbon atoms flying away from them.

此外，由于锯齿型碳管应力能比同口径扶手型碳管的应力能大，使得扶手型碳管比锯齿型碳管更容易形成端口封闭的结构，且锯齿型碳管端口的封闭结构出现相对较多的缺陷，甚至在3000K下会有少最碳原子从端口飞离碳管。

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。
