Abstract:

According to the theory of uhraweak photon emission(UPE)of organisms,the paItial least square re.glession(PLSR)method is used to analyze the major factors to affect the UPE of fish in the propagation period.An equation to evaluate the UPE is then established,and the physical meanings of all the regressive coeficients in the equation are illustrated.Moreover,the primary and secondary factors to affect the UPE of fish are determined. thus coming to the conclusions from the analysis of the PLSR model that the temperature and the gonad maturation coeffi.cient are two notable factors to afect the UPE of fish,and that the avoirdupois, the mass of gonad.the illumination and the salinity have weaker effect on the UPE,especially the latter two
