coverage type造句

• Amtis and aster images were scaled up using pixel aggregation algorithm to find scaling error of surface flux estimation . the results show that the largest error appears at the interface of different coverage types, and the error show much complexity because of the discontinuity of algorithms at these boundaries . additionally, the contamination of building, highway and other ground information also add some error in the estimation of land surface e vapotranspiration
  将amtis和aster图像降低分辨率后计算通量，检验其尺度误差，结果表明，在不同覆盖类型的交界处通量误差比较明显，由于算法本身的不连续性，其误差规律较为复杂，另外，道路、建筑等对通量计算无用的信息也是造成大像元尺度误差的原因之一。
