1纸浆卡伯值与亮度的测量及其重要性显示文摘介绍了纸浆卡伯值与亮度在线连续测量方法,并根据其在北欧几家浆厂的实验,对化验室分析与在线连续测量的结果做了比较。在此基础上,一些原来无法实现自动控制的变量由于有了卡伯值的信号而投入自动控制,从而优化蒸煮过程和漂白过程,减少药品消耗和对环境的污染。Marjatta Ollila (Valmet Automation Kajanni Ltd.,Kajanni,Finland) 1998中国造纸1998,17,5:3
2NUMERICAL SIMULATION METHODS AND THEIR APPLICATION IN MATERIAL HOT-WORKING显示文摘With the development of modern science and technology, especially computer science, the numerical simulation method has been widely used in material hot-working. Mary achievements have been made in this field by using the numerical simulation method. The numerical simulation method, especially finite element method fully described in this paper.Applications of the numerical simulation method in material hot-working are also discussed. Finally, the future of the numerical simulation method is outlined.J. T. Niu, H. T. Li, X. D. Meng and P.

3Effects of Plastic Deformation and Stresses on Dilatation duringthe Martensitic Transformation in a B-bearing Steel显示文摘To provide data for improved modelling of the behaviour of steel components in a simultaneous forming and quenching process, the effects of plastic deformation and stresses on dilatation during the martensitic transformation in a B-bearing steel were investigated. It was found that plastic deformation of austenite at high temperatures enhances ferrite formation significantly, and consequently, the dilatation decreases markedly even at a cooling rate of 280’C/s. The created ferritic-martensitic microstructure possesses clearly lower hardness and strength than the martensitic structure. Elastic stresses cause the preferred orientation in martensite to be formed so that diametric dilatation can increase by nearly 200% under axial compression.M.

6APPLICATIONS OF PHYSICAL SIMULATION IN THE DEVELOPMENT OF HOT WORKING PROCESSES显示文摘Modelling has become a more and more valuable tool in the design, control and development of steel processing. Empirical regression equations, physically based approachs, artificial neural networks and hybrid models are being theied in computer modelling. In all cases, relevant data are necessary, which can be most economically obtained by physical simulation. Physical simulation with a Gleeble simulator has been used in a large number of tasks at the University of Oulu for ten years in cooperotion with the Finnish metals industry. Some examples of these will be described and discussed below, such as the optimization of the recrystallization controlled rolling process, the improvement of the hot strength model for the control of coiling tension and the optimization of continuous strip annealing schedules.Finally,brief remarks will be then on a couple of projects now under way.L.

10Selenium and Cardiovascular Diseases-An Update显示文摘Dietary deficiency of seleniurn has been incriminated in the etiology of cardiovascular diseases. Thus, cardiomyopathy associated with low selenium intake has been described in areas of exceptionally low selenium intake and in patients receiving total parenteral nutrition. Epidemiological studies have provided some evidence for the role of selenium deficiency in the etiology of atherosclerotic disease. An inverse association between the incidence of ischaemic heart disease and selenium intake has been described in population comparisons. The results of longitudinal studies within populations are conflicting. While some investigations have observed a relationship between low serum-selenium levels and the risk of coronary disease, others have not. Final evidence for the role of selenium in preventing atherosclerotic disease can be obtained only from controlled preventionJUSSI K.
