炸药

Polymer bonded explosives are particulate composites containing elastic particles in a viscoelastic binder. The particles occupy an extremely high fraction of the volume, often greater than 85%.

高聚物粘结炸药是一种颗粒高度填充的含能复合材料，其单质炸药晶体的体积百分含量通常达到了85%以上。

And the polymer is so sensitive, it can detect explosive residues on the order of a few millionths of a gram. Often more than a thousand times that amount is left on surfaces.

这种聚合物的灵敏度很高，能够检出几百万分之一克的炸药残余物（通常，接触过炸药的表面含有的残余物是它的一千多倍。
