The development of a kind of subsurface sewage disposal device is to develop a subsurface sewage disposal device which uses physical filtration to improve water quality of some specific area. This device mainly consists of a pressure dissolved air vessel, purification filtrating equipment and a system controller. This device also uses modern control technology to make the water quality meet the requirement of the standard of domestic water and satisfy peoples demand for water by controlling the pressure and flow of water strictly and separate impurities and harmful substances from the sewage.
Abstract-The electronic damage feasibility and the operational characteristics of the high power electromagnetic pulse bomb shot by shipboard gun are analyzed. As the destruction of the electronic components caused by the high power electromagnetic pulse is hard to evaluate, the spatial distribution of the anti-ship missiles is analyzed, and the strategic model for the continuous fire is built. Aimed at the maximum damage effectiveness, the crux of the lasted shift shooting tactics is a TSP problem. The genetic algorithm is applied in the TSP problem. Simulation experiments demonstrate that the model and the algorithm are effective.
This paper examines multi-platform phased missions, which involves a number of platforms working together to achieve a common objective. A simulation model for multi-platform phased mission system reliability analysis is proposed. The model simulates the fault processes of various platforms within mission life by using a modularized multi-platform phased mission system model. With the Monte Carlo method together, the reliability of entire mission and mission phases can be analyzed. A hypothetical example system is used to show the application of this simulation model and the result exhibits that the reliability conditions of system within the mission and each mission phase can be evaluated and controlled effectively.
Now, to the phenomenon of a serious waste of water and low utilization of water resources in our country, a new intelligent water-saving system which can automatically collect cleaner waste water and rain water is introduced, in order to improve the utilization rate of water and save water. Detailed description of how the intelligent water-saving system works, and illustration of the working principle of the intelligent water-saving system; To economize on water resources to the maximum extent, put forward the idea of combing with buildings, so as to collect water through multi-channels; To make the intelligent water-saving system to get extensive promotion and application, bring forward some corresponding measures. In short, the intelligent water- saving system can achieve the maximum water-saving effect.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
