DSM-5 and Clinical Child Psychologyof this phase is sufficient to account for the known behaviour in terms of conventional polymer concepts. A simple discussion of the field is given on this basis with the particular aim of avoiding the confusion often associated with the topic in the literature. The usefulness as a model system deri射手座 发表于 2025-3-25 14:40:10
Electron Microscopy of Crystalline Polymers,ribe the major problems encountered, the methods normally applied to deal with them, and the limitations imposed by radiation damage. Moving on to describe recent developments, some are due to new instruments, particularly the scanning transmission electron microscope, others to methods of increasinobscurity 发表于 2025-3-25 16:51:34

The Crystallization of Polyethylene at High Pressures,t is not, as was once supposed, an example of extended-chain crystallization but falls within the normal class of chainfolded growth. Molecules are indeed usually, though not always, folded within the characteristically thick lamellae produced. It results rather from the intervention in growth above使长胖 发表于 2025-3-26 03:47:46
