摘　　要：利用林芝国家基准气候站2020年4—7月,每日08:00、14:00、20:00人工(测针读数)与对应时次的自动超声波蒸发分钟水位,将所获得的两组数据,采用一元线性回归方法确定其对应关系为:y=0.9662x-40.723。利用公式对2019年4—9月计算所得的月蒸量与自动蒸发月蒸量进行比较,结果表明:绝对偏差和相对偏差都十分小。t检验结果表明:用公式计算出的蒸发量与自动观测蒸发量可合并使用。From April to July 2020,Linzhi National Base Weather Station will use manual(needle reading)at 08:00,14:00 and 20:00 every day and the corresponding time automatic ultrasonic evaporation minute water level to determine the corresponding relationship between the two groups of data obtained by using the univariate linear regression method as follows:.The formula is used to compare the monthly steam volume calculated from April to September 2019 with the monthly steam volume of automatic evaporation.The results show that the absolute deviation and relative deviation are very small.The t test results show that the evaporation calculated by the formula can be combined with the evaporation automatically observed.
