随着我国高科技人才的不断出现,各行业的高新技术也逐渐兴起。对于我国以往的化学工程,化学人员需要进行大量的复杂的数据处理,以及相当有难度的化学实验,这样的做法既浪费时间又浪费资源。因此,在化学工程中进行不断的创新与改革,是我国化学工程技术人员需要研究的重要课题。而MATLAB的出现,是化学工程中的重大创新软件。化学工程人员将MATLAB软件运用到化学工程实验中,可以大大提高数据处理效率,并且节省了很多的人力物力等资源。此软件被广泛的运用到化学工程的各种试验中。本文就针对MATLAN在化学工程与工艺实验数据处理中的应用进行深入的分析与探讨。 相似文献

化工原理实验经常要对大量的实验数据进行处理,且有些数据处理需要一些图形来辅助完成,目前手工计算及采用传统的坐标纸绘图则变得复杂而繁琐。本文以Origin软件为例,针对离心泵特性曲线的测定实验数据,介绍了对实验数据的快速处理和绘制双纵坐标图形的方法。运用计算机软件对实验数据进行处理具有快速、准确和直观等优点,解决了在同一图形中绘制不同数量级纵坐标麻烦的问题。 相似文献

Experimental determination of the laws of color harmony. Part 4: Color preference and the color harmony content 总被引:2,自引:0,他引:2
Antal Nemcsics 《Color research and application》2009,34(3):210-224
In 1956, we decided at the Budapest University of Technology and Economics to start a large‐scale experiment on color harmony. The experiments and the processing of the experimental results have been completed in 2006. These experiments, described in this article, form a study of how much are people, participating in the experiment, influenced by their own personal color preference in judging the harmony content of a composition. These experiments have utilized the results of former (1958–1969) color preference experiments and the system of color preference indexes, which were developed by the generalization of those results. Within the framework of these experiments, conducted between 1998 and 2006 there were 24 compositions, shown to the participants, at first one by one, then in pairs and at last in groups of six. They had to assess the harmony content of the compositions and award a score on a scale between 0 and 10. Each composition possessed a specific amount of harmony content according to the rules of color space, based on the Coloroid harmony threshold and verified by former experiments. In these experiments the number of elementary observations were 135 568. The people participating in the experiment were approximately equal number of men and women, from the age group between 10 and 70 years. During processing, by using the color preference numerical indexing system, we compared the results of those experiments with the color preference of a similar age group, by using color compositions, identical to the ones used in the present experiment. We have found that the sensation of the color harmony and its intensity have a strong relation to how the observers relate to colors and also their color preferences. The sensation of color harmony is also influenced by the gender and the age of the observer. © 2009 Wiley Periodicals, Inc. Col Res Appl, 34, 210–224, 2009 相似文献

More and more information are needed in social life and commercial production, causing significant pressure on the sampling and too much time spent on signal sampling. Compressed sensing is one emerging hotspot in signal processing which employs a special sampling method to capture and represent compressible signals at a rate significantly below the Nyquist rate. In this paper, a Takagi-Sugeno-Kang (TSK) Model based on compressed-sensing sampling theorem is proposed for grinding power. It is further tested by using the actual production data, and the algorithm performance in grinding power model is also analyzed. The experiments show the validity and effectiveness of the proposed modeling method and its bright application foreground in other fields with similar features, such as power, metallurgy and so on. 相似文献
