World Water Policy, Volume 9, Issue 3, Page 456-480, August 2023., 2023 Abstract Groundwater is a vital resource under threat in island communities. Karainagar, a 22 km2 island, is one of seven islands off the coast of Jaffna in Northern Sri Lanka, with its population of just about 11,000 persons, experiences seasonal water shortage, and salinity in groundwater as twin threats impacting on their lives.

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Lithium metal batteries (LMBs) promise ultrahigh energy density, yet their advancement is impeded by dendritic lithium growth and unstable interfacial behavior. Herein, for the first time, we present novel lithiophilic CoNiB quantum dots embedded in nitrogen‐doped hollow carbon nanorods (CoNiB@NC) as a multifunctional interlayer on a ...

Dianci bileiqi, 2017 针对暂态抑制二极管（transient voltage suppressor,TVS）的分布电容与外加电压关系问题,通过对暂态抑制二极管分布电容的理论分析,采用对TVS两端施加反向电压测量其分布电容的方法,利用理论与试验相结合的方法,试验得出:功率为1500 W,参考电压从6.8 V到39 V的TVS的静态分布电容的总体趋势随参考电压增大而减小;外加反偏电压在0 V到反向击穿电压范围内,TVS的分布电容随着外加反偏电压的增大而减小;1.5KE系列的TVS的内建电势为一定值,试验所得约为1.51 V ...

Gaoya dianqi, 2009 针对800 kV氧化锌避雷器(MOA)的电位分布,笔者从数值仿真和试验两个方面进行分析。首先,采用有限元法及ANSYS分析了无并联电容时800 kV MOA的电位分布,得到了所有氧化锌组件(MOR)的电压偏差和每单元内MOR所占电压的百分比,并同时求出各法兰之间的部分电容和对地电容。并联电容后将MOA的"静电场"问题转化为"电路"问题,用节点电压法求出并联电容后的电位分布和MOR的电压偏差。接下来,采用自行研制的光纤测量系统对800 kV MOA的电位分布进行了实测,得出了流过MOR的电流分布曲线 ...

, 2009 手机产品出口到北美地区,需要做FCC认证和PTCRB认证,若手机带有蓝牙功能,还需要做蓝牙认证。FCC认证是对手机安全性能方面的认证,PTCRB认证是对手机质量性能方面的认证,蓝牙认证是蓝牙功能方面的测试以及取得蓝牙标志使用权的认证。只有通过这几方面的认证,手机产品才能被北美地区的运营商所接受。所以对于手机厂家研发人员而言,熟悉整套北美地区的手机认证要求是必要的,也是保证这些认证顺利通过的前提条件。文章通过介绍PTCRB认证、FCC认证、蓝牙认证的基本知识、认证流程以及认证测试内容 ...

Gaoya dianqi, 2018 超、特高压避雷器电位分布的改善通常采用综合均压措施,即在高压端加均压环,同时在避雷器元件上并联均压电容柱。虽然均压电容柱能有效改善避雷器电压分布,但也带来了性能难以检验及参数选择不当会使避雷器运行可靠性下降等诸多不安全因素。通常均压柱中电容器电容比避雷器电阻片电容小很多,电容柱自身的电位分布比电阻片柱更不均匀,局部电容器的荷电率很高,会导致其加速老化,直至毁坏。文中采用有限元法建立1 000kV交流系统无间隙金属氧化物避雷器挂网运行时的三维仿真模型,在给定的均压环配置基础上 ...
