As well, ACA outperforms GA in performance on average. 2. Through the analysis and studying of Ant colony algorithm and Flow shop scheduling problem, a construction graph is introduced. Two ant colony algorithms are proposed and analyzed for solving the flow shop scheduling problem with the objective of minimizing the flowtime. The Initialization of parameters and updating of trail intensities and probability is described respectively and a newly local search technique is proposed. Last is the experiment and the comparison shows that the PACA performs better than the FACA in the case of relatively large-sized problems than in the case of relatively small-sized problems.

The research work done is presented as follows:Compound dewatering technique of vacuum tube well is an effective technology for solving the dewatering problems of aquitard and interface relict water according to physical simulation test and field test. The variation laws, such as degree of vacuum, pore water pressure in different strata, have been studied. The results show that there is a certain scope of influence of vacuum in strata, and the vacuum degree in the horizontal direction decreases gradually with the increase of the distance from the main well; the change law of degree of vacuum in the vertical direction increases firstly and then decreases with the depth of soil strata, and changes with different soil nature and depth; changes of pore water pressure in soil strata has also shown a similar law of degree of vacuum.

Based on the national tenth five magnitude project — Suzhou City Water Environment Improvement and Synthesize Demonstration item, we carried out the static simulation test and the dynamic simulation test under the condition of heavy pollution loading rate and low transparency and dissolved oxygen in polluted river of suzhou ancient city district. These investigations were on the base of the formers' work. We analyzed the purification effects and rules of plant floating-bed technology on polluted river water, and also applied the technology to purify the polluted river water in Miaojia River. Conclusions were summed up in the following:The dominance plant option test was carried out among Oenanthe javanica, Lolium mutliflorum and Allium sativum under low temperature condition. The results showed that the Oenanthe javanica was the dominance floating-bed plant under low temperature condition. Its net removal rate of TN、 NH_3-N、 TP、 COD_ were 51.3%、 65.2%、 55.6%、 57.6%, respectively, and inhibition rate of algae reached 92.3%.
