First, it described three models related to prosody generation. Then it reviewed the researches related to prosody generation in language production, basing on issues they concerned. Most findings suggest that there is an abstract metrical structure which is independent of segmental content in word production. It includes information of stress pattern and syllable number. In the production of phrase and sentence, both prosodic structure and pause pattern are relatively independent and not directly decided...

First, it described three models related to prosody generation. Then it reviewed the researches related to prosody generation in language production, basing on issues they concerned. Most findings suggest that there is an abstract metrical structure which is independent of segmental content in word production. It includes information of stress pattern and syllable number. In the production of phrase and sentence, both prosodic structure and pause pattern are relatively independent and not directly decided by syntactic structure. Prosodic word is the preferred and minimal unit of processing during the phonological encoding of connected speech. The generation of linguistically geared prosody tends to activate the left hemisphere of brain.

首先描述了韵律生成的相关模型。然后以研究的问题为着眼点,回顾了言语产生中韵律生成的相关研究。发现大多数研究结果都证明,在单词产生过程中,存在一个独立于音段内容的抽象韵律结构,其中包含了词的重音模式和音节数量等信息;在短语和句子产生过程中,韵律结构和停顿模式都不是完全决定于句法结构,而具有相对的独立性;句子韵律产生的最佳单位是韵律词。语言学韵律产生的脑区激活呈左侧化趋势。

A series of segmented poly(L-lactide)-polyurethanes(PLA-PU) were synthesized by a two-step method,with oligo-poly(L-lactide)(PLA) as the soft segments and the reaction product of 2,4-toluene diisocyanate(TDI) and ethylene glycol(EG) as the hard segments.The shape memory properties of PLA-PUs were examined.The processed PLA-PUs could recover almost 100% to their original shape within 10 ℃ from the lowest recovery temperature.In the recovery process,the PLA-PUs showed a maximum contracting stress of shape change...

A series of segmented poly(L-lactide)-polyurethanes(PLA-PU) were synthesized by a two-step method,with oligo-poly(L-lactide)(PLA) as the soft segments and the reaction product of 2,4-toluene diisocyanate(TDI) and ethylene glycol(EG) as the hard segments.The shape memory properties of PLA-PUs were examined.The processed PLA-PUs could recover almost 100% to their original shape within 10 ℃ from the lowest recovery temperature.In the recovery process,the PLA-PUs showed a maximum contracting stress of shape change in the range of 1.5—4 MPa depending on the PLA segmental length and the hard-segmental content and higher than that of poly(ε-caprolactone polyurethane)(PCL-PU).Besides,the influence of deforming and fixing temperatures on shape memory properties of PLA-PU was studied in detail.They could affect not only the recovery temperature but also the maximum contracting stress.The experiments of cell incubation were used to evaluate the biocompatibility of PLA-PU.The results show that the biocompatibility of PLA-PU is comparable to that of the pure PLA.This kind of polyurethane can be used as implanted medical devices with a shape memory property.

制备了以聚丙交酯(PLA)为软段,2,4-甲苯二异氰酸酯(TDI)与乙二醇(EG)反应产物为硬段的多嵌段聚氨酯(PLA-PU),并对其形状记忆效应和生物相容性进行了研究.形状压缩50%的样品从起始恢复温度(22~37℃)开始,在10℃范围内可以恢复到起始形状,形变恢复率接近100%,形变恢复力最大值达到1.5~4 MPa.细胞培养实验结果初步证明PLA-PU的细胞相容性与PLA相当,因而有可能用作植入形状记忆医疗器械材料.
