This paper analyses the main factors that affect the copper converter life through the statistical data and describes the relevant measures for its solution; after implementation of these measures,the average service life of the converter after medium overhaul has been extended from 112 heats to 189 heats,the figure of total heats after the major overhaul has broken through 950 and unit consumption of magnesia brick per tone of copper has been reduced from 21kg to 3.7kg.
According to experiment results,it analyzed the main factors that affect the real-time performance of a wireless sensor network,and provided experiment materials for the design of protocol and application.
All the StrA genes were mutated in 204 and SulⅡ genes was mutated in 159,246,384,584,590,591,597,582 respectively. The mutated genes were main factors that produced streptomycin and sulfonamide resistance in Pastuerella.
It is concluded that, due to high viability of these bacteria, the main factor that induced lipopolysaccharide release from the cell wall, irrespective of culturing conditions, is cell division rather than cell death.
The disturbed interaction between the hippocampal system and frontal cortex after kainic acid administration can be the main factor of the revealed cognitive dysfunctions.
The treatment temperature is the main factor affecting the structure of the modified surface layer.
It is demonstrated that the main factor defining the electron loss in magnetic traps in the collisionless limit is the departure of fast electrons from magnetic traps to the boundaries of the structure among other things.
In such devices, the heat transfer by gas molecules is the main factor defining the sensitivity of thermomechanical reading of data.
We thought that the thickness and the spatial distribution of prisms are the main factors that can affect the quality of seawater-cultured pearls.
The main factors that influence the regeneration process were analyzed.
The number of turning channels is one of the main factors that impact the ratio of t10/T.
Nitrogen-containing excretory products of voles accumulating in the soil are among the main factors that determine the activity of these processes.
It is shown that the main factors that form the disturbed flow are the gas enthalpy near the body surface, the local viscous-inviscid interaction level, and the type, either subsonic or supersonic, of the boundary layer as a whole.
The photosynthetically active radiation (PAR) and vapour pressure deficit (VPD) were the major factors influencing diurnal changes in sap flow, which explained 60%-74% variations in sap flow density for all species except Phellodendron amurense.
Because the inventory is one of the major factors that affect the performance of the supply chain system, efficient reduction of an inventory can effectively reduce the cost level of the total supply chain.
It also described major factors and forces of environmental governance, and discussed research advance in environmental governance theory.
Some of the major factors of such regulation are microviscosity of the lipid environment, reactive oxygen species, and intracellular protein kinases.
Major factors affecting the formation of such microspheres are studied.
