基于T型滤波器的调光方法，能在很窄的工作频率范围内实现深度调光，同时具有灯电流波峰因数低的优点。

Based on T type filter, the new ballast can achieve a wide dimming range with a very narrow frequency variation range, and it can operate with low lamp current crest factor.

这并不像欧洲人一两顿不吃东西而感到的饥饿，而是因数星期没有进食而产生的折磨人的深度饥饿，饿得人失眠甚至神经麻木。

Not like Europeans do if they miss a meal or two, but that deep, gnawing hunger that prevents sleep and dulls the senses when there has been no food for weeks.
