Growth rate definition

The absorption band at 300 nm may also be associated with alkah ions, possibly the result of a trapped electron stabili2ed by an alkah ion. The band shifts to longer wavelengths when heavier alkah ions are present, and growth rates for the band show a definite dependence on the type of alkah (205,209). 

C = consumption rate (tonne year ) r - fractional growth rate (% year ) t = time. Chapter 3 Definition of Stress, Strain, Poisson s Ratio, Elastic Moduli... 

Secondly, fractionation effects have been studied [126] where now the components are the various molecular weights in the solution. They conclude that fractionation will be important even at high molecular weights due to the variation in supercooling of the different molecular weights, and hence their different growth rates. Notice that this result could well be affected by the definition of supercooling as described in Sect. 2.3. 

In (7.184) the first term on the right-hand side accounts for the growth rate and the second term accounts for the maintenance. Here the growth term and the maintenance factor are used in their classical definitions. 

Population balances on crystals in a crystallizer require a definition of growth rates in terms of the rate of change of a characteristic dimension ... 

The growth rate G is the temporal change of the particle diameter and the particle flux N is the temporal change of the number of particles. By this definition, the differential rate of change of particles leads to the following equations... 

This behavior is characterized by a plateau region, which prevails above a definite threshold K. It is often referred to as stress-corrosion fatigue because SCC systems usually exhibit this behavior, and the most common theory assumes that the crack growth rate results from the addition of SCC, and pure fatigue crack advance. This is a type of... 

It is easy to verify with the help of solution of Eqn. (2.4.3) in the free-stream that y to j/e have identical growth rate, as one integrates from the free-stream to the wall. From the definition given above in (2.4.9), one gets the following,... 

The reason fi>r the limitation ofx/a 0.3 on these definitions of A, V, and K is that a simplified spherical geometry has been used for these calculations. This limits the approach to small simtering times. Substituting these geometric definitions and the condensation rate, m, into the earlier equation, we obtain a relationship for the growth rate of the neck diameter, x, with time ...
