宽板坯连铸设计的关键在于结晶器内的注流状况，结晶器、铸坯导向段的支撑和二冷喷淋的设计以及连铸自动化。
Critical areas of wide slab caster design will be examined including mould steel flow conditions, mould design, strand guide support design, secondary spray cooling design and caster automation.
酸解淀粉经均相脱支和结晶化可以形成较好的微晶，且酸解时间越长结晶度越高。
The better crystallite can be obtained by homogeneously debranching and crystallizing the acid-hydrolyzed starch. Besides the crystallinity increases as the hydrolysis time lasts.
