moisture equilibrium
1.2. Besides the clay content, specific surface area and organic matter content of soil, temperature also affected the amount of gaseous water adsorbed in soil, and the amount of residual water in samples of desorption equilibrium at 30℃ was more than that at 20℃ while the moisture content of adsorption equilibrium samples at 30℃ was less than that at 20℃ in the general range of the relative vapor pressure.
2.The water activity(Aw) called equilibrium relative humidity(ERH) and the equilibrium moisture content(Me) are two important parameters in lycium processing such as drying,storage and so on.
3.At extreme conditions (i.e. fine powder at 95 ° F and 100% RH) its surface reaches equilibrium saturation at less than 0.50 % of moisture.
4.At normal conditions of temperature and relative humidity (i.e. 77 ° F and 50% RH) its surface reaches equilibrium saturation through adsorption at less than 0.25% moisture.
5.The results showed that temperature of freezing storage had influences on the zein films, which led to the changes of mechanical properties, equilibrium moisture content (EMC), water vapor permeability (WVP).
6.By ultimate withdraw tests of oval-tenon joints made of Pinus sylvestris var.mongolica,Parashorea sp.and Fagus sp.,it is found that their optimal value of interference fit is 0.80,0.47 and 0.26 mm respectively with tenon width to mortise length as wood equilibrium moisture content is 14.0%.
