查询词典 extrapolation

By analyzing the escape of X-ray and Auger electron generated by 37Ar, wall effect of internal gas proportional counter in 37Ar activity measurement was studied theoretically. Escape of X-ray is the main reason for wall effect of internal gas proportional counter in 37Ar activity measurement. Thus, the exponential extrapolation method of pressure was proved correctly.

Therefore, when the grid technique or the district was applied to regionalize spatial scale, individual soil profile are needed more to reduce uncertainties of the estimate of soil organic matter in the grid or the district with spatial scale up, but the uncertainties are smaller when using soil organic matter content in wellestimate gird or district to estimate the grid or district without available data by extrapolation.

因此，采用网格法或行政区划分空间区域，获得空间区域单元内土壤有机质含量或贮量的精确估算需要较多的剖面，但外推至数据不足的空间区域时，估算的不确定较小；采用土壤分类单元为空间区域单元，结果则相反。

It is concluded that the order number determines the precision of temperature extrapolation method, and it can be controlled when the quadratic sum of residual error between the opposite solving and the original measuring is minimum.
