摘　　要：根据计算机测温系统测出的新型平房仓一年当中气温、仓温和粮温的变化数据 ,计算分析了气温、仓温、全仓平均粮温以及各层平均粮温、各区域平均粮温和各方向平均粮温的变化规律 .结果发现 :一年当中最高气温和仓温出现在 7～ 8月份 ,平均最高粮温出现在 9月份 ;最低气温和仓温出现在 1月份 ,平均最低粮温出现在 2月低 ;即平均粮温比气温变化大约滞后 1个月 .上层粮温受气温影响最大 ,一年中平均温度范围为 5～ 2 4 .2℃ ,波动幅度 1 9 2℃ ;中上层平均温度范围为 9 6～ 1 7℃ ,波动幅度 7 4℃ ;中下层平均温度范围为 9 4～ 1 5℃ ,波动幅度5 6℃ ;下层平均温度范围为 1 0 3～ 1 6.4℃ ,波动幅度 6 1℃ .四周粮温受气温影响大小依次为南边 >西边 =北边 >东边 .The annual change regularity of temperatures of atmosphere,headspace and average grain in the whole warehouse,each layer and each area were analyzed according to the data by electronic detect system in a new horizontal warehouse.A yearlong results showed that the highest temperature of atmosphere and headspace occurred from July to August and the lowest in January,and the highest average temperature of grain in September and the lowest in February.The change of grain temperature lagged atmosphere temperature about one month.The average temperature in surface layer of grain mass,middle top,middle bottom and bottom were 5 ℃ to 24.2 ℃,9.6 ℃ to 17 ℃,9.4 ℃ to 15 ℃ and 10.3 ℃ to 16.4 ℃ respectively,and the maximum absolute values in surface layer of grain mass,middle top,middle bottom and bottom were 19.2 ℃,7.4 ℃,5.6 ℃,and 5.6 ℃ respectively.The temperature changes of surrounding grain mass influenced by atmosphere temperature could be listed as followings:south,west,north(the same as west)and east.
