title: [Numerical analysis of finger temperature distribution in a cold environment].
abstract: OBJECTIVE
  Temperature distribution over the finger was discussed, so as to provide reference for thermal protection of the hand.
  
  
  METHODS
  Mathematical model for thermoregulation of trunk including hands was established. In the model, the trunk was divided into 15 segments and the hand was divided into palm and 5 fingers. The model was presented as a consistent set of bio-heat equations and was solved by a finite element method.
  
  
  RESULTS
  Effect of wind speed on the finger temperature is so evident, while the effect of artery blood temperature on the finger temperature is so little.
  
  
  CONCLUSIONS
  Through the comparison with the result of literature, the establishment of the model was proved to be reasonable and the method feasible.
