aEquation (6.10) is used to establish the second equality in Eq. (6.17), which shows that the acoustical velocity of an ideal gas is a function of temperature only. From Eqs, (6.1) and (6.17) the square of the Mach number of an ideal gas is 式 (6.10) 在Eq用于建立第二平等。 (6.1...
From equation (II), SHGC = 44–22 = 22 g C kg−1 for no-till SHGC = 44–18 = 26 g C kg−1 for conventionally tilled farmland SHGC = 44–7 = 37 g C kg−1 for subsoil exposed farmland As management practices are introduced to enhance SOC in these fields, SHG provides a ...
