Abstract: PURPOSE: An automatic broadcast selection circuit in radio set of car audio and method thereof are provided to automatically select and receive a desired radio broadcast (AM or FM radio) by simple operation of a button while receiving a radio broadcast (AM or FM radio) with a car audio. CONSTITUTION: In an automatic broadcast selection circuit in radio set of car audio and method thereof, the method is characterized in that AM radio broadcast received at present is heard to a listener for a desired time if power is applied to an AM radio receiver by pressing a scan button under a state of receiving FM radio broadcast; if the AM radio broadcast is a broadcast to listen, the AM radio broadcast is heard by pressing the scan button for one or more second; if the AM radio broadcast is not a broadcast to listen, the other AM radio broadcast of a different radio frequency is selected by not pressing the scan button for one or more second; at that time, FM radio broadcast that is a radio broadcast heard until the AM radio broadcast of the other broadcast frequency is selected is allowed to be continuously received and heard. Accordingly, since any broadcast to listen is automatically selected concurrently with confirmation of a radio broadcast not yet heard one by one by simple operation of a button under the state that a radio broadcast selected and heard previously with a car audio, a broadcast to listen is conveniently selected and heard without troublesome operation of a button for selecting a radio broadcast.

Abstract: PURPOSE: A standard solution preparing method is provided to enhance the reliability of a standard solution by metering the trace elements of a primer through the neutron active analysis. CONSTITUTION: In the neutron active analysis, an artificial radioactive nuclide is generated from a stable element for the qualitative and quantitative analysis. A radioactive nuclide is generated by irradiating a neutron beam causing nuclear reaction with an atomic nucleus to a sample. The radioactive nuclide is changed to a novel stable nucleus by passing through a decay process corresponding to the inherent half period of respective nuclides while emitting a gamma ray of a specific energy. The qualitative analysis is possible according to the detection of a half period through repeated measurement of the energy of the gamma rays. Therefore, the neutron active analysis is proper to the analysis of the trace elements of a primer. Further, an absolute quantization without need of a standard material is possible.
