In this paper, 35 Tupaia blangeri chinensises captured from Kunming,Yunnan province were investigated. We analyzed hereditary conditionality index about some morphological characters. According to Rife-Buranamanas law, We analyzed the appearance characteristics with hereditary conditionality including color of fur, orbit etc.. The results showed the following: wild fur with seasonal red spot, white fur of abdomen, non-white orbit, fleshcolor palm, non-cocked ear, round tip tail, and the line between the breasts of both sides in a vertical position with axis line.

The principle and the mathematical model of reduced-dynamic precise orbit determination are discussed based on precise point positioning technique by zero-differenced dual-frequency P codes and epoch-wise differenced carrier phase data. Then the key issue in the reduced-dynamic POD, i. e. the pseudo stochastic pulses and their impact on orbit determination accuracy are analyzed.
