Mitigating light pollution impacts on arthropods based on light‐emitting diode properties
Abstract Light pollution from artificial light at night (ALAN) is a significant environmental problem with far‐reaching consequences for ecological systems. Recent innovations in light‐emitting diode (LED) technology may offer sustainable outdoor lighting solutions, but scientific evidence is lacking. We investigated the effects of various LED lighting

Failure analysis of four tube in power station boiler [PDF]
火力发电厂是我国供电主体,约占总体发电量的70%。大型火电厂的安全事关电网的安全运行,而火电厂中的锅炉运行的可靠性是影响发电厂运行可靠性的首要因素,尤其是锅炉四小管的损坏泄漏对机组的安全运行影响最大,是火力发电厂的常见事故,一般占机组故障的60%-70%。锅炉经常由于四小管设计、制造、安装、运行、修理改造、管理等环节的问题以及长期在高温、高压、腐蚀、冲刷等恶劣条件下运行等原因而造成爆管并导致停炉。只有掌握四小管各种类型爆管的失效机理,才能有的放矢开展监督检验工作,寻找有效的管理和技术防治对策 ...
