Some problems of a technique of experimental investigations of cosmic ray variations

Methodological aspects of cosmic ray (CR) variation investigations have been discussed. The experimental data on latitudinal intensity distribution of the total neutron component of CRs and ''stars'' of neutrons with different multiples were obtained from 1975 to 1977 in CR laboratory on the research ship ''Akademic Kurchatov''. Neutron component bond coefficients having different values and varying insignificantly in minimum solar activity years are given for that period. The shore effect has been examined. CR-CR count rate variation due to the CR interaction with a heterogeneous environment (air-soil-water) the value of which varies from 12 to 16%
