The high frequency switch-mode power supply focused by this subject mainly used in galvanoplastics(NDF), electrification(NCF), electrical chemistry(NHF), and excitation(NLF).
The factors which influenced somatic embryogenesis and plantlet regeneration in Picea meyeri Rehd. et Wils. were studied in order to establish a high frequency embryogenetic system.
Brazing quality and product reliability are both increased as using high frequency pulse microplasma arc heating process for assembly brazing of cathode and photoetching grid of electron tube.
But this study does not discover any relationship between CHD and APOA1 gene, APOB gene, APOC3 gene, APOE gene, LPL gene, 30 candidate locus of the high frequency SNPs .
SJ series high frequency deflaker is absorbed the optimum deflaker device in the world by our factory。The device can obviously decrease pulp point and defibraze the fiber with high wet strength.
