HTWS-V is researched and designed by using imported high-precision dew point sensor and the latest digital circuit control technology,which is the intelligent precision instrumentto measure the moisture content of the SF6 gas The instrument uses intelligent self-calibration technology,...
The SF6 Intelligent Dew Point Meter BLS-V is an instrument that uses imported sensors to measure the inert gas in the gas chamber of the equipment. The instrument is easy to measure, easy to maintain, and all components are made of mature and reliable materials, which ...
In this work, we experimentally investigated the optimum plasma etching conditions required to achieve an anisotropic etch profile and analyzed how the optimum etching can be carried out using an appropriate operating pressure and oxygen concentration. Optical emission spectroscopy was used to measure the...
The eight-item Patient Health Questionnaire (PHQ-8) is a self-reported questionnaire designed to measure depressive symptom severity in research and clinical care [7]. It assesses how often in the past 2 weeks, participants experienced eight depressive symptoms. Each symptom is rated on a 4-poin...
2a. The selectivity is a measure of the molecular sieving ability8,35,36,37. The selectivity in the interstitial nanopores decreased exponentially from 60 to 10 at ySF6:yN2 = 0.1:0.9, which is a preferable molar fraction for industrial applications7,8. For the interstitial nanopores, the...
circuit breaker to measure the fracture voltage, and an oscilloscope was utilized to record the arc voltage drop and current during the circuit breaker opening process. Figure 1.Simulated ablation test rig. At the beginning of the simulated ablation test, the test circuit breaker was adjusted to ...
Although the SF6 technique was developed over 25 years ago with the intention that it could be used to measure enteric methane production from ruminants outdoors, no experiments have reported the influence of ambient wind speed, temperature, humidity or rainfall on the accuracy of the technique. Si...
