Presentation Transcript

dimn = L-3(曾用[n]表示dimn)，dimm = M，dimv = LT-1，dimp = (dimF)/L2 = L-1MT-2.
dimp = dim(nmv) =(dimn)(dimm)(dimv) = (L-3)M(LT-1) = L -3MT-.
 = 1， = 2， = (1+)/3 = 1.故由量纲分析得： p  nmv2.
dimp = L-1MT-2= L2-3MT-2 = (L-3)(M)(L2T-2) =(dimn)(dimm)[dim(v2)] = dim(nmv2).故由量纲分析得：p  nmv2.
