The aerosol particle spectrum is consisted of some dispersedphases of small size particle whose distribution is narrow and is hazardous for inhalation.
气溶胶粒度的谱型是由小粒子占优势的分布较窄的多分散相；

The experimental results indicate that PP is incompatible with PU which is as a disperse phase distributed in the PP matrix, the size and shape of the dispersedphases are affected by composition.
结果表明，PP与PU为不相容的两相体系，PU以分散相分布于PP基质之中，其尺寸及形状随组成而变；

The interacting forces between two phases, the pressures for dispersed phase, extra stresses except for pressure and the expressions for energy interchange between two phases have been discussed.
