A container is a collection of interfaces between an application and a platform in an application server.
Containers were born with the development of thin client systems. When developing thin client systems, developers spend a lot of energy focusing on details such as thread safety, transactions, networks, resources, etc., thereby reducing development efficiency. Since these solutions to these details are generally fixed or only parameters are changed, from the perspective of code reuse and design patterns, the developer extracts these low-level details, creates a platform, and provides a certain interface. In this way, business developers do not need to focus on the implementation of these underlying details, but focus on the implementation of business logic.
The container is generally located within the application server and is loaded and maintained by the application server. A container can exist only within one application server. An application server can create and maintain multiple containers.
The container generally conforms to the configurable principle, that is, the user of the container can achieve its own use requirements through the configuration of the container parameters without modifying the container code.
The conventional design of pressure vessels has basically realized computer-aided design. There are specialized software developers engaged in the development of design software, and provide follow-up technical services, constantly upgrading and updating. The commonly used design software, such as SW6, LANSYS, and general-purpose computer-aided design systems based on risk and longevity, are constantly being supplemented and improved during use. Through the secondary development of ANSYS software, which is often used in the analysis and design of pressure vessels and numerical analysis of their components, it has made it possible to provide reliability for reactor pressure vessels, sealing of conventional vessel and nuclear vessel sealing structures, and ultra-high-pressure wire wrapping. The stress field of the container, the temperature field of the packing container, the dynamic response of the explosion container, and the simulation of crack propagation in the pressure container. In addition, numerical simulation software was used to simulate the manufacturing process of the pressure vessel. A valuable attempt was made in the formation of the end cap, the roll-up of the cylinder, the formation of residual welding stress, and the hydrogen diffusion behavior of the stainless steel surfacing layer. result.
