Wheatstone bridge resistor change is mainly caused by the change of material structure, and thus the relative change in resistance can be written as （1） Where are the piezoresistive coefficient and the pressure.
Metal or semiconductor material due to its resistance variation relative change in resistance as a result of （2） Where is the longitudinal piezoresistive coefficient; is the piezoresistive coefficient horizontal; is a vertical stress; is the transverse stress.

Ways of developing individual gaseous extinguishants, which can be produced using the domestic production and raw materials base, are almost exhausted, but the relevance of this issue remains.
In [5], the fluorinated materials developed to replace materials banned from manufacture under the Montreal Protocol are themselves contributors to environment damage.
