EFFECTS OF TEMPERATURE ON LECTROCHEMICAL CORROSION OF DOMESTIC NUCLEAR-GRADE 316L STAINLESS STEEL IN Zn-INJECTED AQUEOUS ENVIRONMENT

The effects of temperature (T) on oxide films for 316L stainless steel (316L S S) in borated and lithiated water without and with Zn injection were investigated by in situ potentiodynamic polarization curves and electrochemical impedance spectra (EIS). The protective property of oxide films in the Zn-free/Zn-injected solu- tion degraded with increasing temperature. With increasing […]

Analysis Method for Temperature of High Voltage Submarine Cable Based on IEC 60287 and Finite Element

The structure of high-voltage cross-linked polyethylene submarine cable is very complex, and the cable laid in special environment. The method of stratification and the parameter calculation are described in this paper according to IEC 60287 standard. The thermal circuit model and the matrix equation are built up to calculate the temperatures of the conductor and […]

Korean Views on Japan's Edo Period Thinkers

Japanese Korean concept is a collection of respect, defiance, aggression in a hybrid in Edo pe- riod. Feelings of respect is from the Japanese island as inconvenient in terms of absorbing the mainland cul- ture. Defiance psychology of Korean is the most noteworthy. Until the 18th century, Japan invaded Korea advo- cates gradually formed due […]

The Geographic Distribution and Historical Development of Address Terms of Grandmother in Chinese Dialects

There are mainly four types of address terms of grandmother in Chinese, ie. Po (婆), Nai (奶), Niang (娘), Ma (妈). The distribution of Po type and Nai type are wider. Po type appears earlier and mainly distributes in the south to Qinling mountain and Huaihe river. Nai type appears later and mainly distributes in […]

Unsteady Heat Transfer Model for Tank Power Device Based on Lumped!. Parameter Method

Based on the lumped parameter method,an unsteady heat transfer model is developed for a tank power device,in consideration of heat transfer in the engine combustion chamber, heat transfer among major engine components, cooling system, lubricating system, and power cabin airflow. The thermal coupling calculations are formulated including the combustion gas and the engine parts,between the […]

Behaviors of vanadium and chromium in coal-based direct reduction of high-chromium vanadium-bearing titanomagnetite concentrates followed by magnetic separation

The reduction behaviors of FeO·V2O3 and FeO·Cr2O3 during coal-based direct reduction have a decisive impact on the efficient utilization of high-chromium vanadium-bearing titanomagnetite concentrates. The effects of molar ratio of C to Fe n(C)/n(Fe) and temperature on the behaviors of vanadium and chromium during direct reduction and magnetic separation were investigated. The reduced samples were […]

Recovering Low-grade Resource in Meiziwo Tungsten Ore

The high-grade bonanza Meiziwo Tungsten Ore has been depleted after 90 years of mining. This paper studied the low-grade (less than 0.12%·m) resource recovery to improve utilization rate of mineral resources. The characteristics of the low grade vein mineral resources, such as thin veins, diverse faults, broken and unstable wall rocks contributes to the difficult […]
