辽宁省泥炭资源及其利用

辽宁省泥炭储量为３５３６．２７万ｔ,分有裸露泥炭和埋藏泥炭。其中辽东山地为泥炭丰富区,以裸露泥炭为主,辽南丘陵沿海为泥炭多量区,以埋藏泥炭为主,其它地区泥炭较少,早期泥炭形成于早全新世辽南沿海,中全新世渐次向北扩展,为泥炭旺盛形成时期,晚全新世南部沼泽被埋藏,北部继续发育,全省泥炭以草木富营养型为主,其中尤以新宾泥炭质量为佳,辽宁泥炭在工业,农业等方面有着广泛的应用。

神经网络在橡胶硫化温度预测中的应用

本文针对难以通过在线测温实现等效硫化控制的情况,在确定硫化条件的直接测温实验基础上,提出了用神经网络模型预测实际生产过程中硫化制品内部温度的方法．在该方法中将所测温度值作为样本提供给神经网络学习,温度采集时刻及易测外部温度作为网络输入,输出值则是在硫化时制品难测温点处不同时刻的内温．神经网络通过学习取得了良好的效果,网络输出的温度值将成为等效硫化计算和硫化质量智能控制的有价值的依据．

Effects of atmospheric pollution on human health

Most air pollutants do not lead to specific diseases. Depending on the pollutant, the concentration and the duration of exposure, some organs are more affected than others. The most frequent disorders are those caused by irritant gases and particulates on the mucous membranes and respiratory organs. The consequences are eye, nose and throat inflammations, diminished lung function, increased susceptability to respiratory infection and a higher incidence of chronic bronchitis. These disorders and diseases are, of course, influenced by other factors as well, such as immune deficiency, allergies, occupational exposure to pollutants, and particularly smoking. The effects of air pollutants are, therefore, multifactorially conditioned and nonspecific disorders are placed in the foreground. Evidence for an association of air pollution with adverse effects on human health is drawn from three sources: animal experiments, experimental human exposures, and epidemiologic studies of exposed human populations. The burden of atmospheric pollution must be reduced to protect human health by an adequate safety margin. In particular, the increased sensitivity of sick and aged people as well as children should be taken into account. In defining the maximum emmission levels, preventive aspects should have priority so as to keep the risk of damage to health and the harmful influences on the environment to a minimum.This article Effects of atmospheric pollution on human health by H. U. Wanner is a revised version of the same article that was first published in the Proceedings of the 1990 European Aerosol Conference; special issue of the J. Aerosol Sci., Vol. 21, Suppl. 1 (1990) 389–396.Reprinted with kind permission from Pergamon Press Ltd, Headington Hill Hall, Oxford OX3 0BW, Great Britain.
