3、ional structure configuration in developing the design, the clear execution of not less than two kind of function structure.It can be executed at the same time and also can be executed in sequence. This kind of structure is usually a composite structure. Its Better to be described as “structure-the
4、system” or” system-structure”,MFS have different levels:,Functions combination. such as coated surface structure or taking the advantage of composites to separate thermal radiation and heat. Embedding sensors and drives made of some kinds of special materials, that is creating the so called “smart”
5、structure. The characters of the “smart” structure are its automatic and intelligence. Embedding the piezoelectric materials is a good way to measure the deformation of the proposed material. Using the structure-electronic components board, circuit boards, or computer chip itself as components or pa
