摘要: Abstract In this paper we have analyzed 222 Rn concentration variation in Domica cave (Slovakia) for the period June 2010–June 2011. that sense applied a complexity analysis on time series. We considered possible existence of periodical component and some environmental parameters, as well correlation between them. addition offered novel measures based Kolmogorov (KC), i.e. spectrum, its highest value (KCM) integral (KCI). These been series: (i) to establish dependence parameters (wind speed inside cave, external wind speed, air temperature, atmospheric pressure CO 2 concentration) (ii) see whether influence make distribution measured quantity less or more stochastic.
