Task 2, sampling this week and next week 3 detected a lake of the aluminum contamination mark, retrieve Lake aluminum material is how the 3 large lakes mid-stream to the analysis, aluminum contamination of the traces on the 3 Lake status of the conversion of the Marcoff link to build found aluminum

The duty two, takes sample Zhou He next week to examine three lakes separately the aluminum pollution traces, how examines the lake aluminum material is in three big lake averages to, the analysis aluminum pollution trace in three lake transformation condition Markov chain, the construction discover

Task II, respectively sampling this week and next week detection three a Lake of aluminum pollution traces, seized Lake aluminum material is how in three big lake in the flows of, analysis aluminum pollution traces of in three a Lake conversion state of Markov chain, building found aluminum pollutan
