文摘Described in this paper is a double-decked vacuum giass isolating set built in the fire cracking instrument. It is characterized by high sensitivity and as being free from sound, electro-magnetic and vibrating interferences from outside thus enjoying the advantages of sound-isolation, shock-proof and no electro-magnetic interference, as well as simple construction, portability lower cost and easy popularization.
