The lowest loss mode fields and the far field divergency angles of output beams of the UPCUR are calculated by use of Prony method. The relations between the mode discriminability, far field divergency angles and the parameters of the resonator are analyzed. And the theoretical results show that the output beams with diffraction limit quality can be obtained by using the UPUR with small magnification (M=1. 3), which is much better than the traditional unstable resonator under the same conditions.

Methods Fifty pairs of fresh colorectal cancer and homologous normal tissues were genotyped with Identifiler Kit and the mutations generated in cancer tissues were determined. The mutation rates, the numbers of locus matched without identical allele (A0), 1 identical allele (A1), or 2 identical alleles (A2) and the number of total identical alleles IA(subscript n were calculated. Frequency distributions of A0, A1, A2 and IA were compared among CR-N group, unrelated individual pairs and full sibling pairs. Discrimination functions were established for individual identification from tumor tissues with discriminatory analysis.
