The results show that the photosensitivity and electrical conductivity of the n -type β-gallium oxide nanostructured layers on a GaS substrate, such as the dependence of the current intensity in the circuit of β-Ga 2 O 3 -GaS structure on the air relative humidity in the range from 42 ...
The diurnal variation pattern at this site in May, a pre-monsoon month, agrees with the known variation of radon concentration in air. However, in June, a monsoon month, it is different, a double oscillation similar to that at the other sites. With the onset of the monsoon, conductivity ...
配电网中性点接地方式 Date Of Publication:2024-12-18 Click-Through Rate:8 配电网中性点接地方式可分为有效接地和非有效接地两大类。 有效接地方式又包括直接接地(中性点与大地直接连接)、经小电阻接地(经阻值较小的电阻与大地连接)、经电抗接地(经感抗值较小的电感与大地连接)3种具体方法。由于单相接地时故障...
一文详尽了解物联网下6大传感器原理 Date Of Publication:2024-12-21 Click-Through Rate:530 本文由环球电气之家整理 现实世界就是一个模拟信号的世界,人通过视觉、触觉等方式来感知世界。在物联网时代,传感器肩负起了“五官”的使命感知万物。万物互联赋予人类生活无边的想象。可以说,当前传感器发展处于多领域全面...
Sliding tests of the Cu samples were performed on a Bruker UMT-TriboLab testers in a ball-on-plate contact configuration under dry condition at room temperature in air with a relative humidity of 50 ± 5%. Balls of 6 mm in diameter were made of WC-Co with a micro-hardness of 17...
One way to increase the conductivity of the GO is to perform the chemical or electrochemical reduction of the material, partially restoring the electrical properties and synthesizing the reduced graphene oxide (RGO) (Bourlinos et al., 2003). This structure has a higher electrical conductivity when...
The FNT electrode exhibited unsatisfactory cycle performance because FNT exhibits low electrical conductivity during the insertion/extraction. However, the initial capacity of FNT/S was ~1346 mA h g‐1 for the first cycle (retention of 21% between the 1st and 220th cycles), which shows a more...
It has a lower molecular weight than air, which means it has a higher thermal conductivity and can dissipate heat more efficiently. It has a higher electronegativity than air, which means it can capture free electrons more effectively and reduce ionization in the arc. ...
①灵敏度高; ②可见做振荡闭锁装置的起动元件; ③在电压二次回路断线时不会误动; ④对称分量的出现于故障的相别无关,故起动元件可采用单个继电器,因此比较简单。7、保护装置符合哪些条件可评定位一类设备?一类设备的所有保护装置,其技术状况良好,性能完全满足系统安全运行要求,并符合以下主要条件: ①保护屏、继电器...
