process
By a simple method (techniques of probability decomposition, renewal process theory) that is different from the techniques used by Hunter (1983), the transient property of the queue with initial state i(i ≥ 0) is discussed.
      
In this paper a class of risk processes in which claims occur as a renewal process is studied.
      
Asymptotic theory for a risk process with a high dividend barrier
      
The overall process involves three steps: preparation of insoluble carboxyl-containing grafted starch copolymer (ISC), formation of precursor (ISC-Co), decomposition of ISC-Co, and phase transition of Co3O4 nanoparticles.
      
The electrochemical behavior of the system was also studied by cyclic voltammetry, and the experiment results showed that the electrode process was an irreversible absorptive with two electrons participating.
      
An advantage of DNB is that it is suitable for the separation of the basic compounds containing nitrogen atoms without a capped process because the spacer containing nitrogen atoms can shield the residual silanols from DNB.
      
Photoinduced intramolecular electron transfer process from C60 moiety to carbazole moiety has been studied by nanosecond laser flash photolysis.
      
The whole set of exponential kinetic equations can be used to model the bioreaction process of protein enzymatic hydrolysis, to calculate the thermodynamic and kinetic constants, and to optimize the operating parameters for bioreactor design.
      
Three 3,4-dihydroxy-2,5-bis-(2'-(4'-substituted-oxazolinyl)) furans were synthesized at 90%-94% yields from reaction of 3,4-dihydroxyfuran-2,5-dicar-boxylic acid or its dimethyl ester with chiral β-amino alcohol via a one-step process.
      
The relationship between the process parameters and the average diameter of polysulfone nanofibers was investigated.
      
The main process parameters studied in this work were the voltage, the flow rate of the spinning fluid, the distance between the spinneret and the nanofiber collector and the temperature in the spinning chamber.
      
It is concluded that the gas-jet/electrospinning is a better method than the conventional electrospinning, in that it makes the nanofibers finer and more uniform and exhibits higher efficiency in the process of electrospinning.
      
Single and pauci chain aggregates of isotactic polystyrene (i-PS) were prepared by the freeze-drying process from dilute solutions with the concentration from 1×10-3 to 2×10-5 g/mL.
      
As a result, the lamella thickness of bulk samples and the samples prepared by the freeze-drying process from a solution of 2×10-5 g/mL was 19.3 and 12.6 nm, respectively.
      
All these results should be attributed to the fewer entanglements in samples prepared by freeze-drying process from dilute solutions, and presented clear evidence for the influence of chain entanglements on the crystallization behavior of polymers.
      
XRD pattern and SEM micrograph showed a good dispersion of ammonium carnallite and anhydrous magnesium chloride crystals with well-distributed big grains, just enough to meet the need for the production of magnesium metal in the electrolysis process.
      
The results indicate that the original number of OSL traps that have captured electroncs is linearly related with the sum of TL decay during the OSL process.
      
The reaction process was monitored by the temporal evolution of the UV-Vis absorption and room temperature photoluminensce spectra.
      
The effects of preparation process on particle size, specific surface area, crystal form and crystalline morphology of the tungsten trioxide was investigated by TEM and XRD etc.
      
We observed that the flow profiles of the scaled-up column were flat during the whole chromatographic process, and the efficiency and resolution of the column were also increased in accordance with theoretical prediction.
