Introduction Recently, with developments in modern science and technology, a functional microwave absorbing material for use in planes, ships, naval vessels and other equipments for military uses and communication facilities for civilian uses have been developed [1-3].
Furthermore, metallic magnetic materials have high electric conductivity, which makes the high frequency permeability decreased drastically due to the eddy current loss induced by EM waves [5].
Usually, excellent EM-wave absorption results from efficient complementarities between the relative permittivity and permeability in materials.

As the temperature rises, the PEEK loses some of its properties, for example, the modulus of elasticity, strength, but the range of operating temperatures for PEEK in the short-cycle process is wider than for other thermoplastic materials.
As for short-term thermal stability, PEEK is at the level of the most stable materials – polyethersulfones, the destruction of which is ~ 1%when heated to 420-430 °C.
Discussion of the Results Because of the high melting point, PEEK is processed by extrusion at temperatures of 370-380 °C, by casting at 380-400 °C, and the production of thefilled composite materials requires even higher processing temperatures.

Architecture and Technique on Internet of Things Guo Xiechao Yan’an University, College of Mathematics & Computer Science Yan’an, Shanxi 716000 Keywords: Internet of things; architecture; technical research; system architecture; Abstract.
And the material is stored in the internal activities, which provide protection for the smooth progress of production instead of profit, so its time value is not high.
The main reason is the production process in manufacturing enterprises changes the material form by handling and becomes products by processing.
As a whole, it has a strong concomitant, but enterprises in the actual operation often carry out some local logistics independently from technical process, such as the optimization selection of transportation path, storage strategy of materials, reasonable distribution of handling and so on, and now most of research is based on kind of such logistics.
