Start determines the start frame of particle emission in absolute time, and Life is a relative value that determines how many frames a particle is alive. Life is relative, because particles are constantly born and emitted, starting on the Start frame and continuing forever, so a particle born at frame 100 with a life of 60 dies at frame 160.

Determining Bulk Powder Particle Size through Texture

Introduction. Particle size analysis is routinely employed for material quantification in a growing number of fields (e.g. pharmaceutical, food, metallurgy).The term "particle size" is not an unambiguous one. Problems can arise if the particles have a very large aspect ratio, such as fibers or needles, leading to disagreements between different particle size analyzers .
