2、e that applies to all machines.(2)You must remember that the laws that apply to air apply to all other gases.12021/8/31(1)A solid is different from a liquid in that the solid has definite shape.(2)In that he is the chairman, he should preside the meeting2An ax is used to apply force to wood.2021/8/3

3、11The answers may lie in a close reexamination of the fossil evidence.2021/8/31Various methods are available for the experimental measurement of the average molecular weight of a polymer sample. These include methods based on colligative properties, light scattering, viscosity, ultracentrifugation,

4、and sedimentation. The various methods do not yield the same average molecular weight. Different average molecular weights are obtained because the properties being measured are biased differently toward the different sized polymer molecules in a polymer sample.2021/8/31Some methods are biased towar

5、d the larger sized polymer molecules, while other methods are biased toward the smaller sized molecules. The result is that the average molecular weights obtained are correspondingly biased toward the larger or smaller sized molecules. The most important average molecular weights which are determine

6、d are the number-average molecular weight Mn, the weight-average molecular weight Mw and the v i s c o s i t y - a v e r a g e m o l e c u l a r w e i g h t M v .E.g.: Its not unusual to see test plans biased toward functional testing. biased toward：偏重（偏倚）于，偏爱：偏重（偏倚）于，偏爱2021/8/31In addition to the d

7、ifferent average molecular weights of a polymer sample, it is frequently desirable and necessary to know the exact distribution of molecular weights. A variety of different fractionation methods are used to determine the molecular weight distribution of a polymer sample. These are based on fractiona
