In this paper,the r—Fe_2O_3 magnetic powder surrounded cobalt of coercive force Hc(700 Oe)is obtained by thesurrounding cobalt reaction of the r—Fe_2O_3 needle shape powder hanged in the strong basicity solution of the differentCo~(2+)/Fe~(2+) mole ratio.
(6) The suitable root-promoting hormone and its processing mode for the needle of Pinus tabulaeformis Carr. to root are the following: Using IBA+IAA(1:1)with 150mg/L or 200mg/L to treat the needle fascicles for 24 hours.
Arginine contents in current needle were 47.55, 43.37, and 29.44mg/100gf. w. during the second fast-growing season in the stands of 5, 10,and 20-year-old respectively,while it were 28.16, 26.42,and 14.95mg/100gf.
The multi-walled carbon nanotubes (MWCNTs) should be assembled with a sharp metal needle of nano-scale radius, for which the FE mechanism is more or less clear.
Using the ArcView Geographic Information System (GIS) platform, a case study was carried out by selecting the population of Pinus massoniana from a needle-and broad-leaved mixed forest community in the Heishiding Nature Reserve, Guangdong Province.
The motion of an ensemble of charged droplets in a constant electric field and in a nonuniform field between a needle-like electrode and a plane has been calculated by the molecular dynamics method.
