Abstract: This article first proposes the research problem of the volume fluctuation value of the pressure regulating room, and then starts from the principle of adjustment, exports the calculation formula of the voltage regulating room water level fluctuations, and determines that after the voltage regulating room water level fluctuation values ​​can be designed and used to use the impedance pressure regulating room with a tattimon, reducing the cost of the project. This research work has theoretical and practical significance.

Abstract: The PDP -based artificial neural grid (ANN) research has now become a hot spot. This article automatically obtains the bottleneck problem for the knowledge caused by the limitations of the first -generation expert system, and introduces the neural network model into the research of the fault diagnostic expert system to effectively solve this problem. At the same time, a more mature BP algorithm is also selected, and a mechanical failure diagnostic expert system is developed in C language. The article also analyzed the problems of neural networks.

Abstract: This article discusses the latest technology of industrial furnace smoke waste heat recovery -the working principle of vacuum phase transformation heat water heater. It has a simple structure, safe and reliable, and can obtain greater heat transfer characteristics under small temperature differences. Combined with the 2T / H steam boiler to recover the tail smoke exhaust waste heat, the heat calculation method is given. This method is suitable for thermal computing of general vacuum phase transformation heat water heaters, simple and practical and guaranteed accuracy.

Abstract: Pleyate dysyate is the intermediate of medicine, pesticides and dyes. At present, the revenue of old -fashioned production in China is only 65 % (based on chloride). This article has reached more than 80 % through a new method of metomyrodolin synthesis synthesis. Product quality and standard samples are consistent.
Miao Tongchen, Wang Wei
Abstract: This article discusses the effect of elastic connection in the dynamic sub -structure method, and obtains the power equation under this condition. This will make dynamic sub -structural methods be more widely used in studying the dynamic, dynamic response and power modification of complex structures.
Yan Jiajie
Abstract: In the comprehensive judgment of the F multi -level, how to reasonably determine the weight distribution of many factors is a key and a problem. This article proposes to determine the multi -factor weight distribution with the AHP method in multiple decisions, thereby giving a more scientific and reasonable method to solve this problem.
