This experiment will oep gene fragments of known molecular method pET expression vector and the connection, and then import into the host cell BL21 feelings among states, and to use a small amount of protein induced by IPTG to express the precise purpose of oep protein. The experimental results show that, when oep gene fragment and pET-22b (+) expression vector and transformed into BL21 host cell competence through IPEG concentration will be induced by 1.0mM, induction time 3 hours, the cells in the host high higher amount of expression of oep protein purity. The initial experiment was to explore the protein's basic purpose of oep optimal experimental conditions and the initial purpose of a certain amount of oep protein, thus the role of oep-depth study of the mechanism to provide reliable experimental material and data preparation。

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。

Abstract: Now the world trade in services rapidly expand, the global economic competition's key point from the cargo trade diversion trade in services, the expansion trade in services, the improvement trade in services structure, is enhances our country to participate in the international division of labor and the competitive ability new action. The current related trade in services's research concentrates mostly to the trade in services globalization, after the liberalization and China join WTO, to the trade in services protection policy research discussion. This article penetrates our country present trade in services present situation, to affected our country international trade in services the correlation factor and the international competitiveness present situation carries on the analysis, the synthesis elaborated the question which our country trade in services development faced, and embarked from our country national condition proposed the corresponding countermeasure, like consummated our country trade in services the legal framework, reduced the market access threshold, the renewal trade in services idea, participated in international trade in services both sides and the multilateral negotiations positively, countermeasures and so on promotion trade in services liberalization, enhanced strong points and avoided weaknesses, developed our country trade in services vigorously, strengthened our country trade in services the international competitiveness, caused it to become our country national economy new economic growth.。
