Methods The operation was divided into two stages. In the first stage, the expander was implanted behind the ear, and was expanded. In the second stage, with autogenous costal cartilage or medpor materials, curve suitable framework, implant and suture it with remnant costal cartilage,overlap it by fascial flap behind the ear and expanded skin flap. Graft skin behind the ear.

手术分2期进行，Ⅰ期在耳后埋置扩张器并进行扩张；Ⅱ期手术以自体肋软骨或Medpor材料为支架，雕刻合适大小的支架，植入后与患侧耳残余软骨缝合，用耳后筋膜瓣和扩张皮肤覆盖支架，耳后区植皮。

Conclution Tissue expenders have morbidity though it can not threaten the life or destroy the contour.In expanding stage, having comprehensive understanding the indications owing to the appropriate treatment at every step to prevent the complication. Treating every step correctly will benefit the second surgical procedure and the satisfactory effects

组织扩张术虽未见发生危及生命或毁形的并发症，但常见并发症发生率较高，影响了施术效果，因此术者在扩张术中应对其全面了解并掌握，严格掌握适应证，取得患者的充分配合，重视扩张过程中的各个环节，以防患于未然。

In the'conclusions', this dissertation emphasizes on the characteristics of the English abroad colonial expansion in the period of the formation of the nation-state. The further conclusions of the paper are as the following. The national spirit transfers to a strong force of promoting the English to go and expand abroad. Their aims are to deny the supreme popish authority, and to challenge the monopoly privilege of Spain and Portugal in the course of the abroad colonial expansion. They intend to break up the old system, of which the universalism of the'Christendom'is the foundation, and to strive for the English right of independence, liberty, and equality in the world.

在&结语&部分，本文着重分析了民族国家形成时期英国海外殖民扩张的若干特点，指出民族主义精神已经转变成一种推动英国人海外殖民扩张向前发展的强大力量，他们的目的就是要否认中世纪以来所谓至尊不二的教皇权威，挑战葡萄牙和西班牙两国在海外殖民扩张中独享的垄断地位，打破以&基督教大世界&普世主义原则为基础的旧世界体系，争取英格兰民族国家在国际舞台中应当享有的独立、自由和平等的政治地位。

In the clinical use of the pre-expanded axial-pattern flap, we noticed that partial necrosis of transferred flap might develop following over pre-expansion.

在预扩张轴型皮瓣的临床应用中我们观察到大量预扩张的轴型皮瓣转移后可能出现皮瓣局部坏死的现象，但目前这方面的研究还比较局限，缺少对轴型皮瓣扩张的安全限度的了解和对皮瓣血液循环立体结构影响的观察。

The regulatory system of protecting the knowledge innovation in patent has internalised such plentiful contents of the knowledge society that it can enrich and expand.

社会的知识化转型中，专利制度保护知识创新的制度体系在内化知识社会时代丰富意涵中得以充实和扩张，其相应的促进机制也因此有了新的运行驱力，专利权正是在多种合力的作用下踏上了社会知识化发展中的扩张之路，这一扩张不可避免的对传统的知识产权制度造成了冲击，保护知识创新也由此面临新的挑战与机遇。

Furthermore, the geometrical ending-profile of an expansion chamber has an influence on both frequency period and amplitude of TL. The appropriate offset of inlet and outlet of an expansion muffler can increase its working frequency range. The findings presented in this paper can be used as a design guideline for a high performance muffler.

结果表明，扩张室为圆形截面的消声器性能优于椭圆形和矩形截面消声器；扩张室端部形状不仅影响消声器传递损失的大小，还影响到传递损失的变化周期；当进出气管之一与扩张室轴线偏离一定距离时，可有效地提高消声器的消声频率，改善消声性能。

Using fluid dynamics FEM (two dimensional, three dimensional andaxisymmetric) and three dimensional acoustic FEM in meticulous analysis ofexpansion muffler structure, this paper studies the influences of each mufflercomponents' position, dimension, form and quantity on the fluid dynamic andacoustic performances;therefore the paper indicates that the end of the intruding tubeis the linchpin of the fluid dynamic performance of the whole muffler structure, thespringhead of muffler fluid dynamic performance is the smoothness of air current, themain factor which affects the acoustic attenuation value of expansion chamber muffleris the grade of saltation of the section of air conducting access, and the attenuationvalue of specific frequency can be dramatically enhanced by carefully designing thelength of expansion chamber.

本文通过流体力学有限元方法和三维声学有限元方法对扩张腔消声结构的参数化模型进行了细致的分析，研究了这种结构的各个组成部份的位置、大小、形状和数量对其流体力学与声学性能的影响，指出插入管端口是影响整个结构流体力学性能的关键，消声结构流体力学性能的根源是气流通过时的平稳程度；影响扩张腔消声量的主要因素为声波传播通路截面突变的程度，并可以通过精细的设计扩张腔轴向长度获得宽频或指定频率消声量的大幅度提高。

Based on the integration of the results of acoustic andfluid dynamic analysis, this paper points out that synthetical acoustic and fluiddynamic performance of muffler can be obtained by using square expansion chamber,by stringing together several podgy expansion chambers, by applying noise absorbingmaterial on chamber walls, by making chambers and pipers co-axial, by adding filletson the end of intruding pipes, and by making the diameter of outlet pipe a little greaterthan the diameter of the inlet pipe.

通过综合流体力学和声学有限元两方面的分析的结果，指出了采用方形扩张腔，采用多个短粗扩张腔串联，扩张腔壁面附吸声材料，使各管道同轴，在插入管端口加上圆角，并且令出口插入管管径略微大于入口插入管管径可以使消声结构获得最佳的声学和流体力学综合性能。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
