general chemistry
4.Methods:The water samples are bottled purified water,filtered tap water,boiled tap water and tubed tap water. Thirty nine parameters of water quality,such as sense character,general chemistry,toxicology,bacteriology,macroelements and microelements,were analyzed with the methods recommended in national health standard(GB5750 85)and compared with the national health standard(GB5749 85 and GB17324 1998).
6.Based on analysis of the fac-tors influencing the calculation errors and adopting suitable techniques to treatthem,a scheme and the correspondent program for solving Kohn-Sham equationhave been presented. With this program,the accuracy of the calculated total energycan posses 8 digitals with reasonable computation efforts. This accuracy is higherthan that of the usual DVM results for 2 to 3 level,and can satisfy the requirementof up to date general quantum chemistry researches.
8.More general and practical quantum control technologies and methods should be explored under the direction of quantum control theory, which is an important step to lead us into the quantum information industry era and is also significant for bond-selective chemistry, gene engineering and nanotechnology.
9.General principles for activities of nervous; Synapse and synaptic transmission; The basic process of classical synaptic transmission; Postsynaptic potential: excitatory postsynaptic potential and inhibitory postsynaptic potential; The conception of transmitter and receptor: mostly transmitter and receptor system; Reflex and reflex arc; The characters of central excitatory transmission, central inhibition; The motor unit of skeleton muscle; Stretch reflex; The function of autonomic nervous system and their chemistry transmission.
10.Abstract This article uses the theory of indistinct linear programme to calculate systemtical-ly the biggest value of the sum total of gang of wells system exploiting value in shenyany paraffin wax chemistry Industry General factory the calculating result is nearer the actual value than the result calculated with traditional method therefore this calculating methed has ex-tensiukly used value.
