The particles of polymetallic nodules in hydraulic hoisting flows that are used for mining in deep sea are rather coarse, therefore their flow velocity is small
During the time of building enterprise information System (EIS), agility of enterprise cant be improved entirely just through implementing the system such as: E
The conventional mass-loss tests and the electrochemical techniques were used to study the inhibition action of LiOH and Na2MoO4 either individually or in diffe
In respect of variable coefficient differential equations, the equations of coefficient function approximation were more accurate than the coefficient to be fro
The effect of high density pulse electric current (HDPEC) on the solidification structure of the low temperature melt(LTM) of commercial A356 alloy was investig
Ti-Al-B alloys were produced by in-situ synthesis method. The phase constitutions, microstructure of these alloys and the morphology of the primary TiB2 were in
To develop a new generation of absorbable fracture fixation devices with enhanced biocompatibility, the biodegradation mechanism and its influence on the cellul
In order to offer high grade concentrate to produce alumina by Bayer, the reverse-flotation technology of bauxite was investigated. The results show that sodium
An approach based on discrete Karhunen-Loeve transformation of the DS/SS signals is proposed to estimate PN sequence in lower S/N ratio DS/SS signals. Character
