The HTV SIR provided the superior hydrophobicity for the composite insulator. But it faces the aging problem more than the inorganics. Corona, as an inevitable influence factor in insulator’s operation, its effect to the material could not be ignored. The paper developed a multi needles to plate corona aging equipment, 1000 hours’ corona aging to the HTV SIR was done. The duration of corona aging effect was study by FTIR, SEM and volume resistivity-temperature character testing. Three testing methods from the aspect of material’s chemical, physical and electrical characters to evaluate the aging effect with time went on. It had good consistency in all three methods for HTV SIR’s corona aging evaluation.

Abstract. Evidence-based assessment is necessary as a first step for developing psychopathological studies and assessing the effectiveness of empirically validated treatments. There are several measures of obsessive-compulsive disorder (OCD) and/or symptomatology in children and adolescents, but all of them present some limitations. The Obsessive-Compulsive Inventory-Revised (OCI-R) by Foa and her colleagues has showed to be a good self-report measure to capture the dimensionality of OCD in adults and adolescents. The child version of the OCI (OCI-CV) was validated for clinical children and adolescents in 2010, showing excellent psychometric properties. The objective of this study was to examine the factor structure and invariance of the OCI-CV in the general population. Results showed a six-factor structure with one second-order factor, good consistency values, and invariance across region, age, and sex. The OCI-CV is an excellent inventory for assessing the dimensions of OCD symptomatology in general populations of children and adolescents. The invariance across sex and age warrants its utilization for research purposes.
