摘要
对风速仪表量值在传递过程中影响其准确度的控制室温度、重力加速度、检定室空气湿度等因素进行了分析，提出了改进意见，使风速仪表量值的准确度在实例环境条件下提高０．７６％。
According to the feature of gas emission at coal face in Panjian Mining Administration,the author considered that the relation of gob gas emission to air supply at coal face comformed to power function and probed into the optimum air supply for coal face.
