The gangue dump was heated using the external heat source, and rainy weather through water mist was simulated. Simulated experiment about explosion of spontaneous combustion coal gangue dump was carried out on the different conditions of the rainfall or not. The unusual gases produced in the course of gangue combustion and the changes in temperature were observed, and their impacts on the explosion of gangue dump were analyzed. The experimental results show that overall warming phenomenon of the gangue dump after watering occurred, the amount of H2 is three times than that before watering, and the amount of CO is far greater than that on the conditions of no-watering, at the same time combining with local observation and tests. It is found that the content of the oxygen reduce with the temperature increasing; however, gangue dump internal hydrogen content increase unusually on the rainfall conditions at 90 ℃, but the local measuring points reach the explosion limit. The existence of the CO and H2 is the main reason for inducing the explosion of spontaneous combustion coal gangue dump.展开更多

These problems include ambiguities in Nietzsche＇s attitude to truth, and the question of how well he can carry through his project of affirming the individual on the basis of a creative reinterpretation of experience. I maintain that Novalis understands language and cognition to be tropic in a similar way as Nietzsche does, and that these writers provide similar critiques of discursive reason on the basis of what they view as its stultifying rigidity and misleading claims to a ＂literal＂ form of objectivity. However, I argue that Novalis avoids Nietzsche＇s difficulties by maintaining that a creative element in cognition does not rule out a variant of a correspondence notion of truth. Although Novalis＇ account thus falls foul of Nietzsche＇s goal of providing an immanent affirmation of human experience, the comparison shows that a Nietzschean attempt to provide a convincing model of individual self-affirmation should integrate a more positive role for trope, which can support a satisfying conception of the value of human creativity.展开更多

The simulation results for the case without natural gas burning is in fair agreement with the experimental results reported in references. The simulation results of different natural gas adding positions indicate that the natural gas burning can form lean oxygen combustion enviroment at the combustor inlet region and the NOx concentration is reduced. The same result can be obtained from chemical equilibrium analysis.展开更多

One exception to this is Michael Rea＇s 2001 definition. The present paper identifies some counter-intuitive consequences of this definition of pornography and seeks to amend it. The aim of the paper is to separate a definitional understanding of pornography from a normative understanding of pornography in order to lay the foundations for future, coherent moral thinking on the subject.展开更多
