栅格计算出现000539错误怎么解决

luorihong

计算地形湿指数，用栅格计算器计算下面公式：con([LX_Fill_1954] == 1,30.33341689,[LX_Fill_1954] == 4,30.33341689,[LX_Fill_1954] == 16,30.33341689,[LX_Fill_1954] == 64,30.33341689,[LX_Fill_1954] == 2,30.33341689*Sqrt(2),[LX_Fill_1954] == 8,30.33341689*Sqrt(2),[LX_Fill_1954] == 32,30.33341689*Sqrt(2),[LX_Fill_1954] == 128,30.33341689*Sqrt(2))。出现000539错误。
