想问你句话,怎么理解,we’d be very worried about these factors of ten differences in the models.,是说这两个模型有10个不同之处,还是模型差异有10倍的关系啊.
为了方便理解 ,这里给出上下文关系.
they have allowed the scientists to start to validate the two models that are being used to forecast the probable future progression of the plume.
One of these models anticipates a maximum concentration by mid-2015 of up to 27 becquerels per cubic metre of water; the other no more than about two becquerels per cubic metre of water.
we’d be very worried about these factors of ten differences in the models.To my mind,this is not really acceptable.We need better studies and resources to do a better job,because there are many reactors on coasts and rivers and if we can’t predict within a factor of 10 what caesium or some other isotope is downstream - I think that’s a pretty poor job"

答案

There are TWO models
Model One= max.concentration of 27 becquerels per cubic feet
Model Two= max.concentration of 2 becquerels per cubic feet
++++++++++++++++++++++++++++++++++++++...
There were TEN differences between the two models,in the paragraph they only talk about these two differences above.
