Times Cited Count：8 Percentile：51.42(Chemistry, Physical)The chemical structures of various ion-beam irradiated isotactic-polypropylene samples were studied. Results of micro-Fourier transform infrared spectroscopy and ultraviolet-visible spectroscopy suggest not only the linear energy transfer, but also the fluence is effective in local transformation of the isotactic-polypropylene.

Characteristics of sound field measurement using a laser Doppler vibrometer (LDV) have been investigated with the aim of evaluating the applicability of the optical measurement method of sound fields to a diagnostic technique for equipment abnormality in high radiation environments. Important aspects of sound measurement using a LDV are discussed based on its dependence on optical path length and sound frequency in terms of anomaly detection and diagnosis in terms of anomaly detection and diagnosis.
