The effect and the action mechanism of lanthanum on GF_(43) plantlet in vitro were studied. The results of experiments show that root growth rate and dry weight of GF_(43) by LaCl_3 treatments increas
The expression of critical size of ferromagnetic microcrystal in an external magnetic field with an intensity of H is derived by means of comparing energies of
