The purpose of this thesis is to use finite element software ANSYS to analyze the mechanical behavior of thin-walled SUS304 stainless steel tubes with elliptic-notched subjected to curvature-controlled symmetric cyclic bending. The mechanical behavior contains the relationship among curvature, bending moment and ovalization. There are two kinds of the elliptic-notch.

本研究是以有限元素分析软体ANSYS 分析SUS304 不锈钢椭圆形凹槽薄壁圆管承受对称曲度循环弯曲负载下的力学行为，其中力学行为包含有曲度、弯矩及椭圆化的相互关系，而椭圆凹槽分为两种，一种为固定凹槽的深度，并改变凹槽的宽度；另一种为固定凹槽的宽度，并改变凹槽的深度。

Adopts the all- air and natural ventilation system for the opening north wall;the floating floor and isolation table to isolate machine vibration,the sounds insulation materials between two walls to insulate noises in the plant;the air conditioning system separately for the audience area and sports area,the fan-coil unit and floor heating system only for the sports area to adapt the use after the Olympic Games,the natural ventil...

针对1层两个比赛厅北墙敞开的特点，采用全空气空调系统、排风从敞开空间自然排出方案；针对空调机房距4个比赛厅仅一墙或一板之隔的特点，空调机隔振采用浮筑楼板加减振台板、隔声采用双墙中间夹隔声材料层的方案；针对奥运会后观众区改作他用、运动区继续作集训使用的特点，观众区和运动区各有一套空调系统，运动区另设风机盘管和地板供暖；针对步枪、手枪射击时产生弹药味的特点，采用吊顶设通风格栅、高窗设电动开启的自然通风方案。

The cantankerous landlady whose crossed eyes stuck out like a pair of taps; the young wife whose neck and head could have been the blow dryer at the hairdresser's; the prostitute with her contagious diseases, squatting like a lion or a dog, garter belt and red silk stocking tops showing beneath her clothing.

譬如说，那暴躁的二房东太太，斗鸡眼突出像两只自来水龙头；那少奶奶，整个的头与颈便是理发店的电气吹风管；像狮子又像狗的，蹲踞着的有传染病的妓女，衣裳底下露出红丝袜的尽头与吊袜带。

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
