Evaporation can accelerate the accumulationofsalts; conversely, through reducing the surface vapor pressure, accumulated salts on the soil surface also can affect the evaporation rate.
相反，表面结晶盐的析出也会影响蒸发过程，通过降低土壤表面蒸汽压抑制蒸发速率。

The used oil and piston deposits after 1-H2 bench test were analyzed. The results show: that the formation of metal salts is the main factor which leads to the accumulationof piston deposits;
