1.求翻译 帮我把下面这段翻译成英文吧,是写在毕业论文上的,求翻译
Since the advent of the information age, people need to accept a lot of information,but the traditional books have already can't satisfy people's needs, so the book born.In order to give the readers more convenient, can whenever and wherever possible to read, do not have to carry a thick book, only need to download an ebook into themobile phone is OK, convenient and affordable. But the simple workers reading textline by line can't meet the needs of people. So, a good overall e-book reader has increasingly become the pursuit of customers. This software is the intelligent mobile phone Android system development based on an e-book reader, it can provide thereading function, and flip effect, Add Bookmark, set the font size, jump progress functions, users can get comfortable reading experience in various different environments. One of the point of improving the user experience is also the software.
Discussion on the application of market of mobile phone e-book reader and thetheoretical basis of this thesis. The paper also makes a detailed analysis on thevarious modules. Using the characteristic design effect and the function of all kinds ofAndroid language is flexible, the maximum to meet the needs of users.
This paper introduces the system development steps and each function moduledevelopment process and methods, but also introduced a variety of programmingtechnology application and development of this project. Relationship between themodule and the module of software development is introduced between the flow chart of the paper, the whole system function description and form.

摘要 Wheel/rail 互作用是主要源泉的铁路噪声。
一个低噪声轮子结构被开发和它 对噪声降低的作用被调查。这个低噪声轮子使用橡胶材料被插入入 钢外缘或登上在轮子表面。
低噪声轮子有低僵硬和一个高阻止的比率 与一个坚实轮子比较。测量表示, 它减少 滚动和号叫。
它结果a 地铁线与提出的轮子能减少它的内部噪声级由4-5 dB(A) 和车振动 水平由7-8 dB 。当提出的结构似乎有为在噪声降低为铁路车, 低噪声轮子的耐力和成本实效将被核实。
主题词: 低噪声轮子; 内部噪声; 辗压噪声; 号叫; 轮子嗥叫 1. 介绍 噪声和振动减少是吸引在铁路操作环境里因为 增加的速度和被减少的车重量为节能有增加的作用 噪声和振动水平。内部噪声和振动陡峭地增加在高速操作期间 并且在轻量级车里由于被传送的损失(TL 的) 减少。
治疗有 被使用国内, 譬如安装障碍为路边噪声和插入吸收 材料为车内部噪声, 但那里是被动措施。 源泉的噪声和振动在铁路操作主要被划分成wheel/rail 互作用和牵引系统。
通常, 在牵引系统, 治疗可能向设备单独地被申请。各种各样的方法为噪声降低适应得根据具体情况 由于wheel/rail 互作用复杂和变化, 譬如定调轮子 用栏杆围研的期间、wheel/rail 螺纹的润滑使用坚实或液体润滑剂, 和低噪声轮子用途。
噪声引起从wheel/rail 互作用被划分入: 辗压噪声在一条平直的轨道, 号叫和嗥叫在一条弯曲的轨道, 和冲击噪声在出席者或路轨联接。号叫是统治的在地下地铁弯曲的轨道。
低噪声轮子应用被学习了在减少号叫的噪声的兴趣由地铁线经营的当局在韩国(Kiyoshi 等1995) 并且在别处(Bracciali 等1997 年; Wonhee 和Jaechul 1999 年; Kiyoshi 等, 1997) 。 本文描述低噪声轮子申请的振动和噪声降低对马达和拖车汽车的在电多个单位(鸸) 系统。
过载信号器被设置在来路不明的飞机框架和在汽车身体的框架之下, 和酣然的米被安装为噪声级的测量在和在汽车之外里面。实验被执行直接和弯曲的轨道测量噪声降低作用根据轨道特征。
