The index-of-reaction equation (i.r.e.): dF/dtZ = kZ(l - βF)m is compared with a generalized Prout-Tompkins equation (g.P.T.e.): dF/dt = kn(l - βF)y With the boundary condition F = 0, t = 0 the equations are equivalent for z = 2 or m = 0 or β ≤ 1 and the i.r.e, is closely approximated by the g.P.T.e. for other values of the parameters by use of the following approximation ∫(1- F)-m dF ≈ AF(1-BF)5 The parameter s is a function of m. Both A and B are close to unity for 1/3 < m < 3. The i.r.e. is recommended as being more useful than the g.P.T.e. because the i.r.e. has a better theoretical basis and because it is more readily integrated and fitted to experimental data.

Growth Accounting

Using a neoclassical production function with aggregate amounts of labour, skill, and capital, earnings inequality is derived as the product of inequality in skills and inequality multiplier. Evidence from growth accounting supports the capital-intensity hypothesis that capital accumulation increases the inequality multiplier. Neutral technological change then raises the inequality multiplier by inducing capital accumulation. The results provide a theoretical basis for Jan Tinbergen's characterization of the evolution of inequality as a race between technological development and education.

We isolated flocculants-producing bacteria F2 from soil. It shows high and stable flocculating activity for Kaolin clay suspension. In order to increase yield of flocculants, we need determine the optimal obtained time. We measured the changes of several parameters using shaking flask experiment, including flocculating- rate, the content of polysaccharide, protein and glucose. It’s showed that the optimal obtained time of bio-flocculants is 21 h. And we built the model about the production of bio-flocculants. Through the comparison of experimental data and the corresponding calculated values from the models, we found that the data joint well and the model can provide theoretical basis for Industrialization of bio-flocculants.

The paper analyzed the adsorption conditions of uranium on carboxylic acid fiber. The isotherms were drawn, and Langmuir and Freundlich equations were deduced. The adsorption kinetics of UO22+on carboxylic fiber was researched. The rate constant of adsorption was obtained and the apparent activation energy was determined. This research provides a theoretical basis for new adsorbents of uranium in nuclear wastes.
