Veterinary Dermatology, Volume 34, Issue 5, Page 393-403, October 2023., 2023 Background – Grass leaf has been suspected to cause immunoglobulin (Ig)E‐mediated immediate hypersensitivity reactions both in humans and in dogs. However, most studies in this area are case control studies without in vitro data showing the involvement of IgE in the reaction.

水电科技, 2022 针对10kV配电线路断路器保护、测量装置需要一般都在电源侧或负荷侧同时接入组合式（电压、电流）互感器。分析了《电业安全工作规程》中规定“带电断接空载线路时，必须确认线路的终端开关［断路器(开关)或隔离开关(刀闸)］确已断开，接入线路侧的变压器、电压互感器确已退出运行后，方可进行。”但是为保证互感器取电正常一般直接接入线路电源侧，而且没有设置控制开关，故无法退出运行。致使无法直接带电断、接带互感器断路器引流线。根据以上问题，本篇文章旨通过对新的作业方法、流程进行研究，在保证不停电情况下退出电压互感器 ...

Design and Implementation of a Central Industrial Apparatus Storehouse Information Management System in Power Supply Industry [PDF]
, 2015 在当前供电行业蓬勃发展的背景下，供电公司的配网带电作业也变得越来越频繁。更重要的是，由于配合带电作业的绝缘工器具种类繁多，往往需要专门的库房和专职人员进行管理；然而传统的工器具库房管理已经赶不上行业的发展变化，因此需要建立一个信息化的工器具库房管理系统。 工器具库房管理系统的主要应用场景借助了RFID技术，在此基础上结合J2EE的技术优势，实现了工器具库房信息的采集、侦听、监控等功能。系统于先进的网络互连，并在此基础上应用了J2EE体系架构，并利用XML语言进行编程。在系统的三层软件架构中 ...
