This paper doesn't research on the general theory and method for valuation, while I try to find a unique way to improve and apply the traditional valuation theory and method in order to meet the need of the new background and new environment. Putting valuation into the value chain background, research on corporate valuation of node corporations of value chain and the value distribution in a value chain, through which the valuation result will reflect the value aim of those companies in value chain and establish a basis for companies to make sure their strategic positions in value chain and to plan their strategy are the main creations of this paper.

The dynamic behavior of an individual polymer chain in the confined system or environment (the extension of a single polymer chain which one end is fixed under the electric field, the translocation process of a single Gaussian chain through a nanometer-scale pore under the electric field, spontaneous recoil of a single chain located in the confined environment) was studied by using Monte Carlo computer simulation. The simulation results can be used to investigate the kinetic law of molecular chain polarization, dipole relaxation and trapped charge carrier under the application of electric field.

From the experiment discovered for the first time the dimethyl ether may substitute CO to take the chain-carrying agent of the peroxy free radical chemistry amplifier system, and optimized the CH_3OCH_3-NO-HO_2 chemistry amplifying system determination condition, the CH_3OCH_3 best density is 1.876 ppmv, the NO best density is 1.3ppmv, and obtained this method chain length CL=124, 5 parallel determinations densities of HO_2 are the 44.0pptv, the relatively standard deviation is smaller than 4%; Although chemistry box model computed result indicated the dimethyl ether, the ethene, the propene and the ethanol all can take the chain-carrying agent of the peroxy free radical chemistry amplifier system, and their simulation chain length all grows up compared to the CO-NO-HO_2 chemistry amplifying systems, but experiments proved the ethene, the propene and the ethanol have not suit the chain-carrying agents.

By employing the Jordan-Wigner transformation and a modified mean field method, we are able to determine its ground-state quantum phase diagram approximately. The chapter IV is the main part of this Thesis. It contains the main innovations in our work. We propose and study in detail a S=1 Ising chain with the interplay of single-ion anisotropy and dimerization. The main results and innovations are the following: We show that the total number of the zero-component of spins at each site is a conserved quantity. This quantity, which may intuitively called as hole's quantum number, is hidden in the system. We show further that the hole's number in the ground-state is zero; By using the Jordan-Wigner transformation, we map this model onto a series of subsystems described by the spin 1/2 dimerized transverse Ising model. We solve the subsystems exactly, by presenting the exact wave functions and spectra;We show that this system exhibits a series of quantum phase transitions by varying the dimerization strength. We determine the quantum critical points exactly. We also show that the criticality is the same as that of the uniform S = 1/2 transverse Ising chain.
