By the study on the different structure and technics , a new structure of single side tfpm with convolute stator and inner magnet rotor is developed . the stator core is made by convoluted silicon steel tape . the stator manufacture does not need punching 通过对各种电机的结构特点及其加工工艺的分析研究,提出了新型的横向磁通永磁电机结构,定子铁心采用硅钢片卷绕结构,转子采用内置式永磁体结构,给出了新结构加工的工艺方法。
Meanwhile , this paper attempts to present a new framework , acting enterprises as a basic unit of analysis , cluing the increasing - returns , applying new theoretical tools , such as new economic growth , new economic geography , new classical economics and network organization theories to study enterprise clusters . at last , i will state a case study on steel tape clusters in nanzhuang village , yucheng county , henan province 本文以企业作为分析的微观基本单元，以收益递增为线索，将新经济增长理论、新经济地理学理论、新兴古典经济学理论和网络组织理论用于企业集群竞争优势的研究，并选择河南省虞城县南庄村钢卷尺企业集群作案例分析。
The paper describes the main techniques in the integral sliding construction for large span structure , which includes jacking scheme , plan layout , assembly , transport and stacking of components , setting of sliding system , setting of track , conformation of falsework , traction facility etc . discusses emphatically the sliding falsework , which includes the material , conformation , manufacture , welding and assembling of the shape steel tape falsework 系统分析了大跨度钢桁架胎架整体滑移施工中的起重吊装机具的选择与布置、施工平面布置、桁架结构拼装单元及滑移单元划分、滑移施工方案及工艺流程、桁架的连接、拼装运输、及堆放、滑移轨道布置、滑移滚轮构造、延伸平台布置以及滑移牵引系统等诸多工艺问题。
