At the same oxidation voltage, the film's corrosion resistance prepaved by triangle wave oxidation is the best, followed by AC oxidation, DC oxidation is the worst.
在相同氧化电压条件下，膜层的综合性能以采用三角波形氧化最为优良，交流氧化次之，直流氧化最差。

When the door switch is closed (car door open) the voltage on pin 8 slowly rises above the negative peaks of the triangle wave producing a short duty cycle output and a dim light.
As the ramp moves farther positive, a greater percentage of the triangle wave will be lower than the ramp voltage producing a wider pulse and brighter light.
