刚接触mixed过程，请高手帮我解释一下以下代码第1，2，4，5，6行的意思：

proc mixed data=mfina1 c0vtest; 1

by stain_name day operator;  2

class washer external product cottonlot temp study;  3

model sri= temp|product/ddfm=kr;  4

random  external washer;  5

  lsmeans temp*product/diff adjust=tukey; 6

ods select  ConvergenceStatus  CovParms tests3 lsmeans diffs; 7

  ods output ConvergenceStatus=status  CovParms=cov tests3=stat lsmeans=lsm diffs=diffs; 8

run;9
多谢！
