本研究的結論是： 1 ）中國股票市場的微觀交易結構並不是採取做市商制度，且2 3的股票不能流通，流通股規模很小，存在著股票股利事件后的快速「填權」效應，使股票價格快速回升，股票股利發放事件的稀釋價格作用無法發揮，也就無法達到「最適價格」 ； 2 ）中國股市的買賣價差的含義發生了變化，不再是實際交易成本的反映，只是可能交易成本的反映，因而很大程度上代表了股價的波動意願，並不具有完全意義上的流動性含義。 3 ）就換手率而言，它既是流動性的衡量指標，也是最常用的衡量投機性的指標。換手率指標只能說明流動性的一個側面，在中國衡量流動性是有缺陷的。A rate - dependent damage evolution modified zwt nonlinear constitutive ralation is adopted, an object function of least square was established according to the experimental results. the searching space of each decision variable was foreordained with conventional optimizing method, and all parameters in zwt model for solidified pf resin were determined with generic algorithms
