用途


B炸药在美国以及西欧国家的军火中非常常见，是从二战初期直至1950年的标准爆炸物，直到一种更安全的炸药开始逐渐取代它的位置。[來源請求] 一些 NATO的军火商，例如Mecar[5] 依然在使用B炸药制造产品。


B炸药与Cyclotol相似，后者有着更高的RDX含量（接近75%）。

Map showing Daylam in western Tabaristan. The Daylamites or Dailamites (Middle Persian: Daylamīgān ; Persian: دیلمیان ‎ Deylamiyān ) were an Iranian people inhabiting the Daylam—the mountainous regions of northern Iran on the southern shore of the Caspian Sea. [1] They were employed as soldiers from the time of the Sasanian Empire, and long resisted the Muslim conquest of Persia and subsequent Islamization. In the 930s, the Daylamite Buyid dynasty emerged and managed to gain control over much of modern-day Iran, which it held until the coming of the Seljuq Turks in the mid-11th century.
