Power integrated circuit is one of the most important branches of integrated circuit . as the bridge of the control and execution part of the system , it plays an important role in the fields of electronic power , automatic control , communication and automotive 功率集成电路是集成电路的重要分支，作为一个系统的控制部分(弱电)和执行部分(强电)的桥梁，它在电力电子、自动控制、家电通信、汽车电子等领域扮演着一个重要的角色。
At the same time , there are increasing requirement on the rational and comprehensive arrangement of the low - voltage and high - voltage electricity system and the information system in modern buildings to avoid the possible conflicts between systems and conduct comprehensive design , construction and installation 同时，现代建筑越来越多地要求对建筑内的强电、弱电和信息系统进行合理的统筹规划，避免系统间可能出现的冲突，进行统筹设计和施工安装。
Because of the worn equipment and the behindhand control means , the loading and unloading coal system has a high occurrence of malfunction and a low level in safety . the coal transportation system of sdkpp formerly adopted centralized electrical control means . advanced control system and management system was adopted in renovation , which made the coal transportation of high automation , perfectibility in management and high practicability 系统设备方面主要由于设备陈旧，控制方式落后，故障率高，安全生产水平低，输煤系统原为强电集控方式，通过设备改造方案的实施，在原有设备的基础上，采用先进的控制系统和上位机管理系统，自动化水平高，管理功能齐全、完善、实用性强。
Currently we have more than 40 technical people in respect of building decoration design and construction , in which 2 are are the senior engineers , 5 hold the medium - engineer certificate , the rest over 30 are the engineering and economic people . therefore we can provide a holistic services from the various electrical lighting , ventilation , cooling , drainage , theft proof , wall curtain etc . now with more than 200 professional workers , the company has passed iso9001 international certificate 现在建筑装饰设计和施工工程技术人员40多人，其中，高级工程师2人，中级工程师5人各类工程技术及经济人员30多人，建立形成了以建筑装饰工程为主，各类电气照明冷气暖通强电弱电给排水防盗防抢设施幕墙技术等相关专业配套技术体系，培养和选聘了一大批高等级技工，专业技工队伍200多人，并获得iso9001国际认证企业。
Abstract : one of the unsolved problems of the high power application of high temperature superconductors is how to lower the energy dissipation induced by flux motion . due to the extremely high anisotropy , small coherence length and weak pinning potential , the mixed state phase diagram which is tightly related to the flux dynamics becomes very complicated . a brief account is given of the field induced crossover of criticalities of energy dissipation , which has been observed in our recent sensitive electromagnetic measurement 文摘:高温超导体在强电方面应用的关键问题是如何克服磁通运动所造成的能量损耗.由于存在极强的各向异性、短的相干长度和小的磁通钉扎势，因此与磁通运动紧密相关的混合态相图变得很复杂.文章综述了根据一系列灵敏的电磁测量所观察到的磁场诱导的能量耗散行为的转变
