机械式SF6密度控制器在运行中时有误报警现象。对国内外已使用过的4类SF6密度控制器的不同结构、SF6温度、环温以及使用处海拔高度对监控特性的影响进行了分析。得出,Ⅳ型国产密度控制器质量稳定、监控精度较好;目前使用的SF6密度控制器对GCB/GIS的SF6密度具有一定的监控作用,但不能避免开关运行时出现的SF6密度示数"假高"现象,为消除密度示数"假高"、对环境温度的欠补偿和海拔影响,根本出路是开发新型智能化的SF6密度控制器。

ABSTRACT Climate change has intensified the need to reduce greenhouse gas emissions, particularly methane (CH4) from enteric fermentation. Genetic selection has emerged as a promising mitigation strategy; however, studies on Bos taurus indicus , especially Nellore cattle, remain limited.

Vitreoretinal complications and surgical outcomes in patients with X‐linked retinoschisis
Abstract Purpose X‐linked retinoschisis (XLRS) is an inherited vitreoretinal disorder characterized by macular retinoschisis. In a subgroup of patients, peripheral retinoschisis can occur, potentially leading to complications such as vitreous haemorrhage (VH) and retinal detachment (RD).

Two‐Dimensional Reconfigurable Photodiode for In‐Sensor Color Filtering and Spectral Logic
By harnessing the photodoping of different aggregates, the device exhibits wavelength‐dependent volatile‐to‐nonvolatile photoresponses that can be reconfigured via bias modulation. This enables in‐sensor color filtering and spectral‐encrypted information processing, eliminating reliance on external optical filters or post‐processing algorithms ...

Sustained growth of sulfur hexafluoride emissions in China inferred from atmospheric observations
Sulfur hexafluoride (SF6) is a potent greenhouse gas. Here we use long-term atmospheric observations to determine SF6 emissions from China between 2011 and 2021, which are used to evaluate the Chinese national SF6 emission inventory and to better ...
