研究发现，建立的方程可预测二元和三元醇胺混合物的密度。
The results show that the densities of binary and ternary alcohol-amine mixtures are satisfactorily predicted.
但如果，密度可能是变化的，因为它是许多金属的混合物，或者厚度在变化等等，但你仍然可以通过对密度积分得到质量。
But if, actually, it has varying density maybe because it is some metallic thing with various metals or with varying thickness or something then you can still get the mass by integrating the density.
适当增加弹体密度可增强这种固态燃料混合物的爆炸威力。
Explosion power of solid fuel mixture can be enhanced with a suitable increase of bomb density.
