According to this law, the surface tension within the full composition of any temperature -water system can be calculated. Through methanol -water and ethanol -water system experimental data test, the average absolute error (AAD) was 5.36 × 10-4n / m, and the average relative error (ARD) was 1.69 %. The result is satisfactory.

Abstract: This article proposes a feasible pipe diameter method. The drainage pipe network is summarized as the sequence of the tube. The initial pipeline network is formed by the establishment of a feasible pipe diameter collection. The feasible pipe diameter is used as a decision variable. This method determines the recurrence relationship based on the characteristics of the sewage pipe network and mathematical logic. Under the premise of ensuring the optimization accuracy, the convergence speed is significantly improved.

Abstract: In order to realize computer communication in harsh environments, this article proposes data processing methods to use cross -digital rotation confession based on the plural rotation confession. The analysis results show that after the plural rotation confession adopts the staggered receipt data, it has strong conflict error capabilities, and proposes a effective method of conflicting error for the computer communication of HF and telephone simulation channels.

Abstract: This article discusses the design and simulation of the self -correction of the papermaking process. One is to combine the SISO system self -correction of the SISO system [1] of the text [1]. To. The simulation results show that this controller still has the characteristics of [1] in the MISO system. The second is to effectively improve the controller parameter recognition method, and propose a practical reciprocity to increase the smallest minimum secondary algorithm (PREIS algorithm). In the algorithm, the P (K) array is negative.

Abstract: Model recognition is essentially a classification method. It can make advanced decisions without the mathematical model of the process. This technology has been applied in many aspects of control, reflecting its superiority to solve the problem of complex systems. This article outlines the application of the mode recognition method in the control system, and points out its possible research direction in the future.

Abstract: This article introduces the software and hardware structure of the single -chip transformer characteristic tester. The article explains the principles of time -segmentation multiplication in power measurement and automatic correction correction caused by temperature, voltage, current, frequency and intestines. The actual operation results show that the instrument has the advantages of high accuracy, small energy consumption, and stable performance.

Abstract: This article mainly studies the voltage current function of the gas discharge lamp in the audio to the radio frequency band. To this end, we adopted the new type of electronic instrument equipment to conduct some new experimental results on the dynamic characteristics of the gas discharge lamp in the band. This result shows that the circuit model of the gas discharge lamp cannot be described by the combination of R, L, C, and its combination.

Abstract: This article discusses how to use the miscellaneous table in a very compressed form to realize the storage of trees. Using this method, the pointers in any tree can be represented by each node 6 + LOG2N Bit (here n is the largest number of children can have a node). So as to store large trees, the required storage capacity can be significantly reduced.

Abstract: This article studies the sub -stable structure and alloy in the AL -8FE -3TI acute cold alloy and changes in the organization and performance during the annealing process. The results show that there are Almf, Al6FE and "V" in the alloy, and there is also a newly discovered rich Ti phase. The alloy is effective in thermal stability.

Abstract: This article uses the energy spectrum analyzer and the gold phase test to study the mechanism of hot cracks produced by the underlying welding relics of the whole Olympic soldier welding seam, as well as the changes in welding material composition and the influence of the welding process specifications on the cracks of the weld. It explores the prevention method of micro -cracks, and obtains the result of certain reference value for production.

Abstract: The impeller curve of the Rogers Drum fan is a gradual opening. To design and mobilize the template curve of the impeller, this article starts with the basic relationship of the gradual opening and calculates it. This method is conducive to improving the tooth accuracy of the wind leaves.

Abstract: This article conducts further theoretical research on the impermanence of the dynamic dynamics of the negative gallbladder. On the theoretical basis, we consider the snail distance changes caused by the boundary conditions and the snail distance changes caused by the effect of the electric field, so that we have obtained a new correction theoretical formula. This formula generally reflects the effects of the threshold voltage of the threshold voltage due to external conditions and the screw distance changes of the electric field induction, and the theoretical formulas of ｚWART and HURALT are only two special circumstances of the above formula.
