开发了一个Ｍｏｎｔｅ－Ｃａｒｌｏ大气扩散模式且引入了一种检验随机数质量的填充二维点格的方法。通过与水槽试验资料对比,说明该模式具有较好的模拟效果。用该模式模拟公路线源的大气扩散,结果表明,高架路和一般公路的污染在地面浓度上的差异较大,而在垂直方向上差异较小。高架路引起的地面浓度值和扩散范围都较一般公路的大。垂直方向上尤其是２０米以上二者基本没有差异,浓度较大值都在５０～１００米以下。结合箱模式的思  相似文献   

Heat expansion of star‐like cosmic objects induced by the cosmological expansion     

E. Schmutzer 《Astronomische Nachrichten》2001,322(4):207-210

The heat expansion of a star‐like cosmic object, induced by the cosmological bremsheat production within a moving body, that was predicted by the Projective Unified Field Theory of the author, is approximately treated. The difference to planet‐like bodies investigated previously arises from another material constitution. The exponential‐like expansion law is applied to a model with numerical values of the Sun. The results are not in contradiction to empirical facts.  相似文献
