While the self-ballasted fluorescent lamp tube is damaged, the ballast also scrapped, resource saving consideration is not environmentally friendly.
而自镇流荧光灯灯管损坏时，镇流器也同时报废，就资源节约考虑是不环保的。
When the ballast parameter is measured in the fluorescent circuit, the fluorescent tube is in a resistance load of low inductance.
把灯管作低感性电阻负载处理，所得参数比较准确。
