Spectral drift of any origin consisting of detectors and nuclear electronics affects the long-term stability in a gamma-ray spectrometer, which is essential to maintaining the high quality of gamma energy spectraThe feedback regulation according to the quantity of spectral drift can restore the system's stabilityA new algorithm for spectral drift calculation is given in this paperA digital logic unit is developed in a FPGA chip based on the algorithm, and a MCU coordinating with it can fast calculate the spectral drift within only less than 110 instruction periods.
Ion-beam-sputtering/mixing deposition was used to produce thin calcium phosphate coatings on titanium substrate from the hydroxyapatite target. The mixing beam could be either Ar + or N + ions. It was found that as-de...

It is much more difficult to obtain failure probability of bottom-events of fault tree by means of traditional method if there has no enough or lack failure information of parts(or modules). In this a
