Theoretical analysis and calculation on the acoustic properties of perforated panel absorber were described herein.

文章对穿孔板背面紧贴吸声薄层时的声学特性进行了理论分析与计算，并与实验结果作出比较。

Spontaneous rupture of esophagus also known as Boerhaave's syndrome, is an extremely severe thoracic disease with high mortality, and is difficult to diagnose because of its rarity and frequent confusion with other severe clinical conditions, such as acute myocardial infarction, perforated peptic ulcer and acute pancreatitis.

自发性食管破裂，又称Boerhaave综合征，是临床上一种严重的胸科急症，因临床少见且易与其他疾病，如急性心肌梗死、消化性溃疡穿孔、急性胰腺炎等混淆，临床诊断较困难，死亡率高。

I'm trapped in a binary punch card factory!

奥迪特恏巴提供客户多样化的可选设备范围：variably式车轮测量18，19或20英寸的直径，带有折叠式靠背桶形座椅，座椅的丝绸纳帕与穿孔或细纳帕特别特穿孔皮革皮革装饰，镶嵌的宜必思白色或黑色漆幻影以及亚光铝寻找外部镶嵌。

MPPs are typically made of a thin metal or plastic panel. However, thin limp panels are generall not suitable as an interiornish of room walls because they do not have sucient strength, which prevent spractica lapplication of MPPs as an interiornish of roomwalls.

典型的微穿孔板为孔径与板厚均小于1mm的金属或塑料板，这些极薄的板材因其强度低，通常不适用于民用，也因此使微穿孔板这一良好的吸声共振结构的应用范围受到局限。

The follow-up periods were various from 6m to 21m. The apical MTA barrier technique was used to manage pulpless permanent teeth with incomplete root formation. The postoperative radiographs showed complete repair of periradicular tissue in 5 of 7 teeth and improvement obviously in other 2 teeth. Only one case (1 tooth) had a 3mm periodontal pocket in four perforation repair cases. The lesion at the perforation sites was improved obviously.

追踪观察时间为6-21月。4例穿孔修补的病例，均为延迟修补，除一例为根尖1／3处的病理性吸收外，其余患牙的穿孔部位位于牙根的冠1／3或根分叉处，一例6m复查时有3mm的牙周袋形成，其余患牙骨吸收暗影均明显缩小。7例根尖发育不全并无髓牙的病例均为成人，5例根尖暗影完全消失，2例明显缩小。

The results are unsure for experimental use;The rabbit's corneas that were removed with upper-half of corneal limbal epithelium lamella and erased the center corneal epitheliums were transparent with intact corneal epithelium;In the approach,the corneal and limbal epitheliums were burned with a cotton swab socked in 1 mol/L NaOH,there were 4 rabbits' corneal stroma happened perforation or ulcer and symblepharon,and the other one presented corneal epithelium phenotype.This is an applicable method to create the pathological model of corneal limbal stem cell total deficiency.

结果表明，处理后4周，全周角膜缘上皮板层手术切除，中央角膜上皮层用1 mol/L NaOH擦除的5只试验家兔角膜表面全部血管化、结膜化，未发生睑球粘连，角膜基质胶原纤维完整未见溃疡、穿孔等病变，细胞印迹学检查为结膜表型，可作为实验性角膜缘干细胞移植的病理模型；全周角膜缘上皮板层手术切除，中央角膜上皮用生理盐水擦除的5只试验家兔，有2只为结膜表型，另3只为角膜表型，观察期内结果不稳定；半周角膜缘上皮板层手术切除，中央角膜上皮层用生理盐水擦除的5只试验家兔，角膜表面透明，全部为角膜表型；直接用1 mol/L NaOH擦除角膜缘和中央角膜上皮的试验家兔，有4只角膜基质胶原纤维断裂、溶解，并伴有严重的溃疡、穿孔、睑球粘连等病变，不能用于移植试验，另1只角膜表面透明，未见结膜和新生血管长入，细胞印迹学检查为角膜表型。

You simply lay each single conductor down inside the 66 block's two metal teeth and punch the conductor down with a special tool, called a punch-down tool.

你只需将一根电缆接入66型接线板的两个金属锯齿，然后使用一个称为穿孔工具的特殊的工具对电缆进行穿孔。

The experiment shows that the catalyst portion has very obvious effect on the exhaust purity box ,purity ratio and oil consumption ; In the course of the opening ratio has an less obvious impact on experiment ,the three items ;the least impact on the three items is the carrers diameter.

试验结果表明，催化剂用量对净化消声器的消声量、净化率及油耗三项指标均有显著的影响；穿孔板的穿孔率在试验范围内，对净化消声器的三项指标影响较为显著；载体直径对净化消声器的三项指标的影响次之。

If you get your piercing done with a gun and have an earring literally shot into your earlobe, tiffany pendents , necessities , you'll find that that ends to give you a piercing at an 18 gauge.

如果你的穿孔这方面做了枪，并开枪的耳环字面到您的耳垂，蒂芙尼吊坠，必需品，你会发现结尾，让您在一个18针一穿孔。

Plunder melds and run with this jewel!
