Fourth, Based on sample data collected in Shenzhen city in 2003, the paper, from various perspectives, calculates nominal VAT rate for goods sold domestically or internationally. By the means of the calculation of the extent of indirect nominal tax burden shifting, we can get the economy tax burden from evaluating some trades'tax burden shifting range of Shenzhen VAT taxpayer. This paper also analyses the problems and the reasons of it and proved that the result of the separate calculation of domestic sales nominal tax burden and export sales tax burden can more realistically reflects the enterprises'nominal tax burden.. Enterprises with higher nominal tax burden can transfer their most parts of their nominal tax burden to the consumers, but the enterprises with lower nominal tax burden have to bear all nominal tax burden. Thus, when measuring the properness of tax burden from the VAT taxpayer, a comparison between economic tax burden and optimum tax burden should be considered.

In the chapter three, by using the comparison principle and frequency domain method of the discrete systems with time-delay, combining Rouche Theorem, sufficient criterions for the stabilization of the neutral type discrete control systems with multiple time-delay and the neutral type interval coefficient discrete control systems with multiple time-delay are obtained by choosing appropriate feedback controller.

The comparison was made of amplitudes of the postsynaptic potential evoked in AP cells by the stimulation of T, P and N cells. The results showed that for each type of T, P and N cell the contralateral member of the pair evoked larger synaptic potentials in the AP cell that did its ipsilateral homologue and the T, P and N cell with a dorsally situated receptive field produced a larger synaptic input on the AP cell that its counterpart with a ventrally situated receptive field.

In this paper, an efficient and easy biological screening method based on the sensitivity to lovastatin of Neurospora crassa was built to deal with the mutant strain rudely by UV mutation. A high-level strain was screened in the shaking flask culture incorporating with TLC and HPLC. A comparison between this two methods also was originally discussed while identifying dyeing using bromophenol blue as the better treatment of TLC, and offering a kind of simple, practical, fast and economical determination qualitatively and quantitatively.

At first it may seem rather strange to treat the chemistry of the halogens and the noble gases,two groups that represent the extremes of chemical activity and inertia ,in the same section .the superficial differences between the halogens and the noble gases are much reduced,however if we focus our attention on the comparison of halide ions(particularly F-) with the isoelectronic noble gas atoms and the noble gas compounds with halogen atoms or the halogens in their higher positive-oxdation states.

The above results showed that physiological AAI pacing maintained a normal EAS and VAS, and improved or enhanced VSS; while nonphysiological VVI pacing and physiological DDD pacing induced the decrease in VSS due to an abnormal EAS and VAS. Furthermore, with increasing the pacing rate, VSS was markedly decreased.The quantitative comparison of parameters of left ventricular systolic function obtained by computerized ERNA showed that AAI pacing induced the significant increases in ventricular ejection rate and stroke volume with concomitant shortening of ejection time.
