Abstract: This article aims to develop a new type of phosphate reactor -a single groove and double -zone four paddle reactor (RTCB reactor) with a curve similar to the Taiji graphic curve. First, use tap water and phosphide to perform cold mold experiments for the mixing medium. The results of the cold mold experiment show that the RTCB reactor has the advantages of low power consumption, suspension, good mixed effects, and reasonable residence time distribution. Then, the same two -water process process conditions were adopted, and the Douer trough was used for reference to perform the heat model experiments. The results of the heat model showed that compared with the Douer groove, the RTCB groove has the advantages of saving power, superior phosphide crystalline environment, and slightly high phosphide washing rate. The research work in this article will provide a basis for the further development and application of the reactor.

Abstract: The thermodynamic properties can be represented by the number of functions in mathematics, so it must meet the nature of the vehicle’s secondary function. This article applies the nature of the number of functions and the relationship between the thermodynamics, such as the relationship between the strength and the nature of the capacity; why the entropy is the capacity of the capacity; Formation derivation and so on.

Abstract: This article is proposed that the eight -shot mechanism is connected in series with the psychic crack slider mechanism and other agencies. When the eight -shot mechanism is turned into a nine -shot mechanism, the nine -shot mechanism can form a piston -to -section curve. This article also analyzes the error of institutional cutting workpieces.

Abstract: This article combines the random description of the runoff process with the fuzzy dynamic planning, and establishes a fuzzy system fuzzy dynamic planning model (SFDPM) for the optimized scheduling of the reservoir. Because SFDPM is preferably in the [0, 1] domain, it has the advantages of easy computing, less computer memory, and fast calculation speed.
How to compete for glory
Abstract: This article determines that the best pH value range of activated carbon adsorption is 3.5 to 5.0, and it is found that with the adsorption process, the pH value of the solution will increase and exceed 5.0, resulting in a decrease in the absorption of activated carbon. For this reason, a new adsorption device has been developed, so that the adsorption process is always performed within the best pH value range. In the single -pillar comparison experiment, the work adsorption capacity is doubled by about double the fixed bed.

Abstract: Through interior tests, the factors affecting the performance of silicon powder concrete were studied, and their strength and slumps were selected to meet the coordination ratio of silicon powder concrete with small wave base engineering design requirements. The test results show that in the case of the same cement dosage, the strength of silicon powder concrete is much greater than that of ordinary concrete. Compared with ordinary concrete, silicon powder concrete, splitting and pull -up in the same age; pressure -resistant bullet molds, the strength and limit stretch of the axle are slightly increasing. The resistance of anti -rushing resistance is significantly improved, and the resistance of anti -penetration has improved significantly. Silicon powder concrete is an excellent new type of anti -abrasion material.
