The mesh simplification technology plays an important role in computer graphics, reverse engineering, cultural relic protection and other fields which involve 3D modelling and dynamic demonstration. The geometric elements decimation algorithm, as one of triangle mesh simplification algorithms, has many advantages over the other simplified algorithms. The(More)
The catalytic cracking method of PAHs for the pyrolysis gaseous products is proposed to control their pollution to the environment. In this study, the Py-GC-MS is used to investigate in situ the catalytic effect of CaO and Fe2O3 on the 16 PAHs from Pingshuo coal pyrolysis under different catalytic temperatures and catalyst particle sizes. The results(More)
