Firstly, phenyliodine diacetate was immobilized to the 2% cross-linked polystyrene or the liner polystyrene resin. The more iodine the resin had, the lower conversion to phenyliodine diacetate. We made our endeavor to extend the range of useful application of polystyrene supported phenyliodine diacetate in organic synthesis:(1) the reagent was used as an effective reagent of carbonyl regeneration from oximes and semicarbazones of ketones.(2) the reagent was also applied to the synthesis of 1, 3, 4-oxadiazoles, 1, 3-disubstituted-2-pyrazoline, 2-arylbenzoxazole from aldehyde N-acylhydrazones, aldehyde hydoazones and phenolic Schiff's bases respectively.

首先，我们以2％交联的聚苯乙烯和线性的聚苯乙烯树脂为载体，制备了聚合物负载的二醋酸碘苯，通过研究发现：(1)聚苯乙烯二醋酸碘苯是酮肟、缩氨脲有效的去保护试剂，不仅芳香酮，脂肪酮和α，β不饱和酮的肟、缩氨脲也能顺利转化为相应的酮，实现酮基的再生；(2)我们还利用此试剂，分别与醛的N-酰基苯、N-酰基苯腙及邻羟基芳亚胺反应，在温和的条件下发生成环反应，以良好的产率生成1，3，4-噁二唑、吡唑啉和二取代苯并噁唑等杂环化合物；(3)聚苯乙烯二醋酸碘苯还可有效地将邻羟基芳酮的酰腙经氧化、重排成1，2-二酰基苯。

According to Interpretative Theory of Translation, in interpretation, interpreters listen and identify the phonetic sounds of SL through analysis, synthesis, inferences and association; at the same time, they comprehend the heard information through analysis, synthesis, and inferences with the help of knowledge of themes and other cognitive knowledge, and they also take notes to help memorize the comprehended meaning; at last they re-express the information in TL completely and accurately.

释意派理论认为，口译教学是训练学生通过分析、综合、推理和联想等方法在听辨原语语音的同时，借助主题和认知知识进行分析、综合、推理，达到正确理解听到的信息，并利用笔记帮助记忆理解的意义，在讲话人完成一段讲话后，准确、完整地用译入语表达原语信息。

S the computation power and the memory capacity increase, the corpus-base speech synthesis system has become the best and most popular speech synthesis system. Based on the system, the linguistic features are first derived after the text is parsed, then some appropriate units are selected as candidates. Finally, the well-pronounced speech is synthesized by concatenating the best unit sequence by the synthesizer part of system.

bstract：随著计算机之运算速度及记忆体容量的加快与增大，以大型语料库为基础之语音合成系统已成为目前最普遍且品质最好的语音合成系统，其方法是先输入欲合成之文字后，再经过分析得到语言参数，接著在大型语料库中依据所得到之语言参数找到对应之候选合成单元组，最后透过语音合成器挑选出最合适的单元组进行串接以得到合成语音。

So the flexible HEN problem in the low temperature processes is more evident. Most papers focus on the flexible synthesis of two-stream HEN. The research on the flexible synthesis of multi-stream HEN is limited because of the complexity of the problem and the difficulty of finding the global optimum solution.
