Traditional studies on materials and techniques are mainly undertaken by engineers of structures and materials, while architects play the role in the application of materials and technologies.
Architectural Science System QIAN Xuesen system holds such an opinion that the object of architectural science is an open, complex and giant system that bears complexity, openness and is of the big science. [2] It can be divided into three levels, namely basic theory, technological sciences and engineering technologies.

Properties of Samples from Polymer Materials Manufactured by the Additive Method V.T.
According to the technology of manufacturing products from polymeric materials, there are materials obtained by the method of casting, centrifugation, pressing, vibrocompression, as well as materials manufactured using frame technology [5–7].
In recent years, the efforts of researchers have been directed towards the creation of materials on additive technologies.
The physical, mechanical and operational properties of the same materials from different manufacturers may differ.

Meanwhile the explosion suppression effects of absorbing materials were studied tentatively in explosion chamber which can simulate mine gas explosion.
In order to compare the absorption effects of different aqueous materials, the same flow and same spray time should be set in every experiment.
Then methane absorption experiments were carried out using different materials and pure water.
