• Tunneling condtrctance spectra of' norutaal uaaetal /instrlator /triplet strperconductor .j trnctions areinvestigated theoretically, As triplet paring states xve select several types of sytntaaetries that areprornising candidates for the sttjoercondtrcting states in UPt3 and in Sr3Rtr0,j. The calctrltrtedcondttctstnce spectra 211(' sensitive to the orientation of the jttnction which reflects the anisotropyof the pairing states. They show either zero-bias conductance peaks or gatp-like stt'tucttures de-pending on the orientation of tire jttnctions. The existence of a residtral density of states, peculiarto nontrnitary states, is shown to haxze a significant infltrence on the properties of the condtrctancespectra. Present restrlts serve as a guide for the experirtaentaJ determination of the s3zrntnetry of'the pair potentials in UPt3 and Sr,zRtt0,).
