2. Mathematical period: For a function f (x), if there is a non-zero constant T, so that when x takes every value in the domain, there is f (x + T) = f (x), then the function f (x) is called a periodic function. The nonzero constant T is called the period of this function.

BIM is more and more widely used in the construction industry. Based on various relevant information data of construction projects, building models are established. By adopting BIM, construction companies can use consistent information to design and optimize projects throughout the process, and can also support better communication through visual appearance, so that all parties to the project can understand the cost, construction period and environmental impact. BIM supports architects to better predict the completed buildings before construction, so that they can maintain their competitive advantage in today's increasingly complex business environment.

Simply speaking, the local object focuses on executing the code on the page, while the proxy controls when the local object is instantiated and used. We have used some proxy patterns in the above monomer patterns, that is, using proxy patterns to instantiate the monomer patterns, and leaving other things to ontology objects.
