The results from the study on the decoloring conditions of strain 3# showed that the pH range for decoloring reaction was 5～11 with 6 ～7 being the optimum, the temperature range was 10～30℃ with 30℃ being efficiency optimal. The decoloring efficiency was higher under the presence of oxygen than that lack of oxygen. Strain 3# could more strongly decolor malachite green under optimum conditions. The decoloring rate was above 50%, 70% and 90% in 4, 12 and 24 h treatment, respectively.

By comparing the application effectiveness and economical efficiency of several major piles types used in soft soil area, it was been indicated that these piles types were all defectively on bearing capacity or economical efficiency, while the rigid-flexible, long-short pile composite foundation could make full use of its bearing capacity, reduce the quantity of piles, and satisfy settlement and bearing capacity requests.

本文首先综述了复合地基及复合桩基的基本理论和发展概况，通过对深厚软土地区几种常用桩型应用情况及经济性能的比较，指出现行的几种常用桩型都不同程度地在承载能力或经济性上存在一定的缺陷，而通过比较表明刚柔性长短桩复合地基能最大限度的发挥复合地基的承载力，以减少用桩量，并满足工程对沉降和承载力的要求，因此，具有良好的经济性。

Light output analysis tests character of spectrum radiate of pyrotechnic mixtures and analyses wave band distribute of light by comparing different static blaze spectrograms of the pyrotechnic mixtures. Screen out the better pyrotechnic mixtures according to request of pumping source. Press experiments in airtight erupt container experiment, which simulate the circumstance that pyrotechnic mixtures deflagrate in quartz pipe, realize the press influence to the quartz pipe wall and the disciplinarian of axes press variety. Apply these pyrotechnic mixtures to Nd:YAG lasers as the pumping source and compare pumping efficiency of different pyrotechnic mixtures. Pumping efficiency is an important standard which checkout if these pyrotechnic mixtures are the better pumping source. Sensitivity experiment analysis incarnate security of pyrotechnic mixtures that is the essential parameter in the process of design, manufacture and use.
