Furthermore, transfer coefficient between total content and variable speciation including acid-soluble/exchangeable, reducible, oxidisable fraction of heavy metals are different. Transfer coefficient of total Cr is 0.65 in tailings area, but that of variable speciation is 0.26. In contrast with Cr,transfer coefficient of total Ni is 0.26, but that of variable speciation is 0.67. The similar characteristics on Pb and Zn in cultivated soil, namely, transfer coefficient of total Zn is high, but low for variable speciation, which is reversed for Pb. Transfer coefficient of total content and variable speciation in abandoned soil are low compared with above two fields soil, especially, variable speciation of Cu and Ni are not transported almost down soil profile.

In this master thesis, we mainly discuss the adjacent vertex- distinguishing total chromatic numbers of some special graphs and prove that Zhang"s conjecture holds for these graphs. Then we get the adjacent vertex-distinguishing total chromatic numbers of the Halin Graphs. Moreover, we investigate the Generalized Petersen Graphs, prove that some classes of positive integers can"t structure the Generalized Petersen Graphs and get the result that the adjacent vertex-distinguishing total chromatic number is 5. Finally, based on the number and the parity of circles contained by the graph, we get the adjacent vertex-distinguishing total chromatic number of two classes of graphs.
