摘　　要：金属薄膜电桥结构是影响发火与安全性能的决定因素，通过磁控溅射方法设计制备了2种不同结构的薄膜电桥，并对其发火与安全性能进行了分析和测试。具有良好热散失性能的蝶形电桥结构抗静电能力强、具有良好的安全性能，是一种安全型的电发火器件。The structure of the metal film bridge is the impoltant decisive factor to in influencing the firing function and safety function. The two different film bridges were are produced by file magnetron sputtering, and file firing function and safety function were are tested and analyzed. The papilionaceous film bridge with the better hot heat dissipation ability can resist the static electricity and has the better security, and is the a kind of secure electrical igniter.
