title: [An experimental study of effects of active-heating-system for extravehicular spacesuit gloves on working performance].
abstract: OBJECTIVE
  To observe the effects of active heating system for spacesuit gloves on extravehicular working performance.
  
  
  METHODS
  After analyzing the factors with gloves influence on the working performance, the effects of active heating system for gloves were studied experimentally with aspects to fatigue, hand strength, dexterity and tactile sensing.
  
  
  RESULTS
  1) Heating-system had not influence to grip; 2) Heating-system had 17% influence to fatigue except specific person; 3) Nut assembly and nipping pin showed that heating-system had little influence to dexterity; 4) Apperceiving shape of object and two-point distance showed heating-system had little influence to tactility.
  
  
  CONCLUSIONS
  The active heating method is rational and has little influence on working performance.
