The testing results show that the system is effective in controlling refrigerant constituents and capacity and enables a significant increase in the seasonal energy efficiency ratio.
On a seasonal scale, the results indicate that the rainfall ratio of stratiform rain to deep convective rain is proportional to their rainfall pixel ratio.
在季节尺度，对流云和层状云降水的比与两者的面积比成比例关系。

Conclusions Moving seasonal mean ratio method could consider secular, seasonal, cyclic and random tendencies of time-series data together and could serve as a useful tool for prediction.
