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.

During the pipe pushing construction of the parallel steel water pipeline of Beidu-Yanger pipeline project in Ningbo, the pushing force in main pushing power station appeared unusual increasing and the construction had to be interrupted. Through the analytical comparison between theoretical and practical pushing curves as well as the analytical comparison between the tool pipe track and the form map of pipeline resting in soil, it was found that the excessive pushing force in main pushing power station was caused by excessive deviation adjustment angle which enabled the pipeline to over bend in a short distance.
