Abstract: This article divides the sublimation and activity of the sublimation type catalyst into four categories: that is, parallel sublimation; series sublimation; tongue sublimation and independent sublimation. The asexual and loss dynamics of the phrase component on the carrier is given. Prove that Levenspiel’s dynamic dynamic dynamics can be applied to the research of sublimating catalysts.

Abstract: Based on the boundaries of the boundary element, this article proposes two types of infinite boundary units, and applies it to the foundation simulation problem, giving a reasonable position of infinite boundary unit. Example calculation shows that the infinite boundary unit has the advantages of saving units and high accuracy.

Abstract: Liang Hezhu is a load -bearing component in the building. Their shape and mechanics are closely related. This article uses some typical instances and pictures that the shape and mechanics of the beams and pillars are unified complexes, and it shows that mechanics is often the source of architectural shape inspiration. Mechanics should broaden the scope of architectural art to create more beautiful buildings.

Abstract: This article briefly describes the basic principles of the sequential method. It illustrates some issues that should be paid attention to when applying, and finally use this method to monitor the vibration of the main pump of the nuclear power plant, and draw the comparison of forecasting and measured results.
Yang Guozhan;
Abstract: This article adopts a 3-D limited unit method, and the engine blades are calculated and calculated on stress. When forming a unit rigidity matrix, an uncoordinated displacement mode and coordinated displacement mode were adopted. This article also gives a basis for the stress changes and stress concentration factor at the dangerous cross section, which provides a basis for the life expectancy and reliability analysis of the leaves.

Abstract: This article conducts model recognition and adaptive control of the aircraft simulation heating device. The model recognition uses the ARMAX (N) recognition device. The identification results and mechanism analysis are consistent. The adaptive control uses two algorithms of STCCAMAC to meet the requirements of performance indicators.
Liu Xianlin;
Abstract: This article uses a linear method to establish a dynamic stable analysis model containing a multi -machine power system dynamic stable analysis of synchronous generator damping winding.

Abstract: The three pillars of modern civilization are described in this article: energy, materials, information, and the close relationship between the problems such as food, environment and resources currently concerned by humans are closely related to the development of inorganic chemistry.
Huang Rengui;
Abstract: This article conducted a further mathematical analysis of the spindle radial graphic movement, and obtained the vector form of various curve equations described by the movement. They were of extensive significance; the motion analysis of the spindle radial graphic motion was used using these equations; clarifying the positive harmonics of the standard balloles of the standard ball heart radial error, which was not related to its non -positive harmonic. Related; the physical significance of standard ball eccentricity is clarified.

Abstract: This article discusses a type of display method designed by the author designed to a dedicated system. Compared with the general algorithm, the calculation time, the expenditure and graphic display effect of the storage space have improved.
Wang Shubin; Xing Jia Province;
Abstract: This article considers a type of multi-dimensional high-level Burgers-KDV-type equation group. The period of time is overdone, and the principle of viscosity removal and Leeay-SChauder’s non-moving point proves the existence of the overall weakness of the problem. Finally, the approximity of Zhejiang’s nearly solved.
