Indian police have found a large cache of plastic explosives in Bombay, the type used in last month's serial bombings that killed more than 300 people.

印度警方在孟买发现了大量塑料炸药，上个月造成300多人死亡的系列爆炸袭击就是使用了这种炸药。

It basically consists of a series of explosives bonded together with a plastic binder and a chemical, usually 2, 3-dimethyl-2, 3-dinitrobutane, to identify the type and source of explosive.

它主要包括了有塑料粘合剂黏在一起的一系列炸药和一种化学产品。 这种化学产品通常是2,3-二甲基-2,3-二硝基丁烷,用来确定爆炸的类型和起点。

The impact sensitivity of plastic-bonded explosives (PBX) is significantly smaller than that of without plastic, because plastic may improve the surface property of explosive crystal.

塑料粘结炸药(PBX)的机械撞击感度远低于单纯炸药，这因为塑料包覆层改进了炸药晶体表面性质。
