BACKGROUND
Ageing and associated cognitive impairments are becoming serious issues around the world. In this study, the physiological properties of three kinds of complexes of fatty acid (capric, stearic and oleic acid, respectively) and de‐branched starch molecules were investigated via a d‐galactose‐induced ageing model. This study revealed differences in the regulation of cognitive impairment...
This paper conducted experiment research on enameled wire used in inter-turn insulation of JD117 inverter-fed motor and focused on twisted pairs as test object. Bipolar pulse voltage aging test was conducted under various frequency and time; dielectric frequency and temperature spectra of specimen were measured and analyzed; combining with Scanning Electrical Microscope (SEM), the influence of different...
Isotropically conductive adhesives (ICAs) have always been a hot spot in producing UHF RFID tag antennas with low cost for mass-production and low conductor loss.[1] As an interesting motif of flexible electronic component, they can also be integrated into sensors or as biocompatible electronic components in tissue engineering applications.[2] Considering the cost-effectiveness and the requirements...
It has been shown that the supply waveforms generated by the power converters play a major role in inverter-fed traction motor insulation degradation. The electrical characterization of these insulating materials is often carried out through aging tests which may provide estimation of life under different stress levels and conditions. However, deeper investigation of aging phenomena due to supply...
A life time recorder is advisably required in the ageing life testing of dielectric material , because parallel testing of multi-samples is allowed with less time costing and more exact result. Based on the thermal measurement to monitor and record the state of the dielectric samples, a recorder is presented in this paper. When some samples are broken-down,the rapid rising of temperature of the limiting...
