Experimental synchronous rotor internal mixer and two kinds of 55L synchronous rotor internal mixer, consulted a number of published articles at home and abroad, then, for the first time, formed four kinds of physical model and the corresponding mathematical model which related to the mixed stock between the mixing chamber side and the top of the rotor wing, to the mixed stock between the two rotors and to the mixed stock at the various temperatures of the mixing chamber. And from the character of model, the author gave the relevant analytic solutions and finite element approximation arithmetic solutions during the experimental process of the synchronous rotor internal mixer.

因此,本文作者在XM—1.7实验用同步转子密炼机和两种50L同步转子密炼机上进行了大量的实验,并参阅国内外已发表的文献和资料,首次建立了同步转子密炼机混炼过程中,胶料在转子棱峰与密炼室壁之间、胶料在两同步转子之间和密炼室中混炼胶温度变化的四种物理模型及其相应的数学模型,并根据所建模型的特点,分别给出了相应的解析解或有限元数值解。

The application of the lattice Boltzmann method in unsteady open channel flows was studied in detail in the paper. An existing lattice BGK model was mended; For the problem of negative local equilibrium and evolutionary distribution, we proposed a lattice Boltzmann model based on cell-population equilibrium, which is a direct non-negative approximation to the continuous Maxwell distribution. The model reduces the transport and collision, two basic evolution steps in the LB model, to transport of the non-equilibrium distribution.

Along with the evolution of the theory of CIM, the need to intellectualize CIM systems raises. Accordingly, the need to intellectualize enterprise modelling architectures also brings forward. By the research of the 1st chapter, the author discovers that there are three areas in an enterprise modelling architecture can introduce intellectual techniques, viz. modelling framework, modelling method and simulation. Whereas most architectures, such as CIMOSA, ARIS, GIM and PERA, can not satisfy the above-mentioned requirements.

经过第一章研究分析,本文作者发现在企业建模体系结构中的建模框架、建模方法和仿真运行三个方面能够引入智能化方法,即在建模框架中增加通用性维来降低建模难度、缩短建模周期和提高模型的可重用性,在建模方法中全面引入面向对象方法实现建模元素和企业模型两方面的构件化,在模型仿真时应用人工智能领域的成果并提供决策支持。

Based on lots of literature and information, this paper has engaged in deep studies and brought forth a new kind of matchboard cement concrete pavement.

As a result of error distribution\\\'s non-uniqueness, draws out to the standard deviation understanding again, by about standard deviation reflected that the erroneous zero rank value two side the variation targets, the application unimodal distribution fits the error distribution, the goal is: By approaches the rationality which under the enhancement goodness of fit\\\'s premise determines to the error.

从文章的上下文感觉此标准值似乎是人为规定的,并不受实测数据本身分布的影响,不具有客观性。个人认为:研究在实际中实测数据相对于均值的分布更有意义。按照作者的观点,误差的分布都是单峰的,除了正态分布这种对称分布外,作者认为还有不对称的偏峰分布。因此研究这种偏峰分布模型可能更有意义。
