31. The notion of particle size distribution reflects this polydispersity. 32. There are many methods for measuring particle size distribution . 33. However the particle size distribution of the dust is somewhat shallower than in the Amalthea ring. 34. Rain drop size distribution ( DSD ) is an important consideration for studying rain fade characteristics. 35. In Village Creek, Texas, blacktail shiners revealed size distribution patterns consistent with a protracted spawning season. 36. It is also defined as pore size distribution . 37. It can also be a measure of the number of modes the targets size distribution has. 38. The size distribution is often of critical importance to the way the material performs in use. 39. A similar change in slope has been observed in the size distribution of the Kuiper belt objects. 40. A consistent particle size distribution is a reason for spray drying some industrial products such as catalysts.
