【Abstract】 Abstract The experimental researches revealed that ambient temperature, atmospheric humidity and gravity acceleration were key factors to influence the precision of ventilators’ pneumatic behavior test. So a proposal was put forward for improvement, whicn raised the test precision by 1.36% for full pressure effciency of ventilators.更多还原
