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.

Then the article starting from the activity, which relates the person with exterior nature,namely the human society work practice, elaborates the nature which worked as the foundation of humanity labor,and the human could not leave it and are bringing it into line with the nature as the work essential factor of labor process; The realistic nature similarly also cannot leave human as persons work creation, and this is the question of two aspects.The thesis has analyzed the work and natural relations in the agricultural society and in modern industry society ,and obtains the conclusion that the different ecology values can form under the different production method. This article criticizes disassimilation work in the capitalist society not only causes the disassimilation relationship between the human, but also creats the disassimilation which human and nature related, and proposes the communism society not only is the society in which the contradictory exploitation between human and nature is solved, and the contradictory relation between human and nature is also solved.
的结论;其次从人与外部自然相联系起来的是活动,即人类社会劳动实践出发,论述了自然界作为人类劳动的基础,人类须臾离不开它,人是把自然界作为劳动的要素而纳入自己的劳动过程的;现实的自然界作为人的劳动创造同样也离不开人,这一个问题的两个方面,并分析了在农业社会中劳动与自然的关系和近现代工业社会中劳动与自然的关系,得出在不同的生产方式下会形成不同的生态价值观的结论,批判了资本主义社会的异化劳动不仅造成了人与人之间关系的异化,还造成了人与自然之间关系的异化,提出共产主义社会不仅是人与人之间对立矛盾的剥削与被剥削关系真正解决的社会,也是人与自然之间破坏与被破坏的矛盾关系真正解决的社会的论断。
