细胞和细菌
堆积在毛囊, 青春痘就形成了。 这种毛囊堵塞被称为粉刺。
粉刺的顶部可能形成黑头,或白头。 当这些黑头和白头破裂后,里面的油脂和细菌会

来自主题: WaterWorld版 - 布鲁塞尔甘蓝有什么营养价值?
Whatever cooking method is employed, overcooking is avoided. Overcooking
releases the glucosinolate sinigrin, which has a sulfurous odor. The odor
is the reason many people profess to dislike Brussels sprouts, if they've
only tried them overcooked with the accompanying sulfurous taste and smell.
Generally 6–7 minutes boiled or steamed is enough to cook them thoroughly,
without overcooking and releasing the sinigrin.

7 The Obliteration of Sodom and Gomorrah

out of the heavens. 25 Thus he overthrew those cities and the entire plain,
destroying all those living in the cities—and also the vegetation in the

希腊火:
This fire is made by the following arts. From the pine and the certain such
evergreen trees inflammable resin is collected. This is rubbed with sulfur

这算个购机吧的火药啊
