江津润湿时间的温度分布研究

The study of TOW distribution in room temperature of Jiangjin site

采用直接读取、4点统计、24点统计三种方法研究了江津试验站1998年的润湿时间的温度分布,研究表明,可以利用全年每天2、8、14、20点的4个数据统计年润湿时间的温度分布;江津地区润湿时间的温度分布特征主要为:(1)99％的年润湿时间是在5℃至30℃温度范围,每月润湿时间的温度波动一般为15℃;(2)在(0～5)℃、(5～10)℃、(10～15)℃、(15～20)℃、(20～25)℃、(25～30)℃、(30～35)℃区间内,4点统计法各区间润湿时间的百分比分别为0.34％、13.4％、24.5％、18.3％、26.0％、17.4％、0.0％。

The TOW of TOW distribution in room temperature of Jiangjin site in 1998 was studied with direct reading,4 - point statistic and 24 - point statistic. It was proved that 4 data of 2 hour,8 hour, 14 hour and 20 hour every day can be used to calculate the TOW distribution in room temperature, The characteristics of TOW is distributed between 5℃ and 30℃ and the monthly temperature variation of TOW is 15℃. (2) in the tempera-ture rang of (0-5)℃,(5-10)℃,(10-15)℃,(15-20)℃,(20-25)℃,(25-30)℃ and (30-35)℃,the TOW percentage is 0.34%, 13.4%,24.5%, 18.3%,26.0%, 17.4% and 0.0% respectively with 4 - point statistic mathod.
