Abstract: Crossing the finite element method is one of the basic means of random structural analysis. However, the discussion of the difference between the difference between random parameters and definitive parameters is rarely discussed. This article tried to do this work. The article defines the concept of the closer of the M -level accuracy of the random switch answer. Through discussion, the possible research direction of the closing finite element method was pointed out.

Abstract: This article explores the process and mechanism of long -effect phosphorus pesticide photocatalytic degradation by detecting the intermediate product and final product of long -term phosphorus pesticide photocatalytic degradation. It is believed that the photocatalytic degradation of the long -acting phosphorus pesticide is caused by the · OH attack; the degradation first occurs on a more acidic ester group. The photocatalytic degradation of triteromyate is formed by the removal of fatty people hydrogen by the TIO2 surface · OH attack.

Abstract: This article discusses the finite element method of the solution to the problem of cone sliding bearing lubrication. For Renault equations that appear in the form of polar coordinates, the corresponding limited element computing formula of polar coordinate form is to reduce repeated coordinate transformations in the calculation process to improve the speed and calculation accuracy. Lubrication problem. A practical verification was performed and a satisfactory result was obtained.

Abstract: CELLALANURALALALALKS has been by L. since 1988, L. O. After CHUA and others were proposed, they have made great progress and have been applied in many fields. In this article, only the problem of stability in the basic theory of CNN studies a non -linear mechanical properties containing a triple neuron CNN autonomous system. The method of simulating the computer reveals various cycles and chaos phenomena in this system.

Abstract: This article uses the basic solution of the opposite sex board to establish a direct boundary element format of plane general opposite sex issues. It can solve the problem of orthogonal or general opposite sex materials. Examples show that the solution of the heterosexual boundary metad to the problem of stress concentration has a high calculation accuracy.

The article explains the weighing prediction compensation method to improve the weighing accuracy. The system hardware structure diagram and software frame diagram is given. The system design is reasonable and simple in structure. Accuracy <0.8 % (500 grams per bag).

Abstract: Summary, this article has analyzed a state analysis of the longitudinal failure caused by the three -phase oil switch during the operation or in the interpretation of the three -phase oil switch during operation or in the interpretation. It proposes the idea of ​​rapid judgment of fault judgment with status current.

Abstract: This article is raised on the basis of the evaporation of alkaline evaporation. The algorithm of the alkaline of the alkali concentration FU Y. The actual operation results show that the concentration measurement has a high accuracy, thereby realizing the automatic discharge of alkaline evaporation.

Abstract: The discrete control system is widely used in production practice. This article proposes a new method of solving the mathematical model of discrete control systems -the mother function method. This method can solve the problem of linearly discrete systems. It can also be partially solved the problem of non -linear discrete systems. It can be used as an extension and supplement to the iterative method of conventional use.

Abstract: This article takes into consideration the initial overlap of the multi -variable iron magnetic chain group with Gilbert scattered items. Under appropriate conditions, the presence of the overall strong solution is proved to adopt the Galerkin method and the principle of firmness. And obtained the existence of overall weakness of the initial value of the corresponding iron magnetic chain group.
