摘要：
The coefficient of friction (COF) of grains has been evaluated as a function of ambient temperature and relative humidity (RH) on aluminum and galvanized steel surfaces. The COF increased with an increase in RH for low grain moisture at low ambient temperature. For grain with a high moisture content (18.6% wheat, 16.4% canola, 21% lentil), the COF decreased as the RH increased to 70% and 85% at high ambient temperature. Temperature emerged as an important parameter influencing the COF, especially when associated with high RH.
