Difúze izotopů 67Ga a 68Ge podél hranic zrn v niklu
Čermák, Jiří ; Rothová, Věra
The 67Ga and 68Ge grain boundary diffusion in polycrystalline nickel has been investigated by the radiotracer serial sectioning method
Difúze hliník substituujících prvků podél hranic v Ni3Al
Rothová, Věra ; Čermák, Jiří
The grain boundary diffusion of 67Ga and 68Ge as Al-simulating elements in the Ni-rich Ni3Al alloys has been investigated using the serial sectioning method

2004 Program of Development in Metrology. Final Report on Project M/53/04: Implementation of the time and frequency CMC table in the BIPM KCDB database
Čermák, Jan ; Buzek, Otokar ; Čemusová, Blanka ; Šojdr, Ludvík ; Pánek, Petr
The report summarizes the activities of the Laboratory of the National Time and Frequency Standard- CMI Associated Laboratory provided in the field of "Time and Frequency Calibration Services" to elaborate the Czech CMC table and to submit in to the BIPM KCDB database.
2004 Program of Development in Metrology. Final Report on Project M/19/04: Time and frequency primary standard
Čermák, Jan ; Buzek, Otokar ; Čemusová, Blanka ; Šojdr, Ludvík ; Pánek, Petr
The report brings a summary of the results obtained by The Institute of Radio Engineering and Electronics /IREE/ in the field of primary time and frequency metrology realizing the M19/04 project of The Metrology Programme of the Czech Office for Standards, Metrology and Testing in the first half of 2004.
Introduction to time and frequency metrology
Čermák, Jan
Basic concepts such as time interval, time scale and synchronization encountered in metrology of time and frequency are introduced. Attention is paid to frequency staility. Also described are the methods of accurate time transfer applicable in the territory of the Czech Republic /GPS, DCF long-wave transmission, internet/.
Measurement of time and frequency
Čermák, Jan
Basic methods of time and frequency measurement are described. Attention is paid to measurement of period, frequency and time interval based on reciprocal time-interval counter. Stanford Research 620 counter serves to illustrate the case. Also mentioned is the calibration/measurement capability of the National Time and Frequency Standard.
