Sekundarni naslov:	Establishing influental quantities for the purpose of Princo 469 NOVA TM Economy model mercury barometer reading reduction
Sekundarni povzetek:	My thesis thoroughly examines influences, which directly affect mercury barometer readings. In order to obtain true values of the air pressure, the following influences must be taken into consideration: mercury temperature, Earth's gravity, correction of the instrumental error, which includes the influence of inaccurate instrument setting and the influence of scale error, capillarity and defective vacuum space. With regard to the indicated influences the value of air pressure is obtained at standard temperature and gravity. For the purpose of individual barometer readings comparison, the readings must be reduced to the mean sea level or reference level, where the geopotential altitude of a barometer is needed. So as to establish individual corrections, the value of the acceleration of gravity on barometer level and the altitude of the barometer had to be determined. Due to above mentioned influences this thesis discusses the Earth's gravity field and vertical systems that were used. Finally, readings on »Princo 469 NOVATM Economy model« mercury barometer have been made providing that all the required reductions have been carried out.

Povzetek (ePrints):	V nalogi so podrobneje opisani vplivi, ki neposredno vplivajo na odčitek na živosrebrnem barometru. Za pridobitev prave vrednosti zračnega tlaka, moramo upoštevati naslednje vplive: vpliv temperature živega srebra, vpliv zemeljske težnosti, instrumentalni popravek, ki zajema vpliv nenatančne postavitve, vpliv napake skale, vpliv kapilarnosti in vpliv nepopolnega vakuuma. Ko upoštevamo navedene vplive, dobimo vrednost zračnega tlaka na standardni temperaturi in standardni težnosti. Za medsebojno primerjavo posameznih odčitkov barometrov, moramo odčitke reducirati na srednji nivo morja oz. ničelni nivo, za kar potrebujemo geopotencialno višino barometra. Za določitev posameznih popravkov smo morali določiti vrednost težnostnega pospeška na nivoju barometra ter višino barometra. Zaradi navedenih vplivov je v nalogi podrobneje opisano zemeljsko težnostno polje ter višinski sistemi, ki so v uporabi. Za konec je narejen še odčitek na živosrebrnem barometru Princo 469 NOVATM Economy model, za katerega so opravljene vse potrebne redukcije.
