The Last Quarter of the Moon is a novel written by Chi Zijian,which describes the life of the Ewenki ethnic minority in northeast China.The novel has received wide attention for its profound theme and unique narrative style.Defamiliarization is a technique commonly used in literary creation.By breaking the conventional expression mode and changing the conventional view,readers can have new feelings and understandings.The original text of The Last Quarter of the Moon describes the life of the Ewenki minority in China,which has a strong defamiliarization effect.In the English version,the translator adopts various methods to reproduce this defamiliarization.Through the analysis of its English translation,this paper discusses the defamiliarization embodied in it and the two translation methods used by the translator to reproduce the defamiliarization of the original text:alienizing translation and hybridization.It is found that the translation successfully retains the unique charm of the original text by means of language and cultural defamiliarization,enabling English readers to obtain a new reading experience,and revealing the important reasons why the English translation of The Last Quarter of the Moon can be successfully translated and spread in the Western world. 展开更多

This paper describes a combinatorial Synthesis of the Mannich Bases in Solution through the Mannich reaction using 3 ketones, 5 amines and formaldehyde in solution and hydrochloride as a catalyst and then using a macroporous quarterized ammonium resin (CO32- form) as a scavenge agent to remove the acid catalyst when the Mannich reaction is completed. It was found by GC/MS analysis that the symmetrical ketone, such as acetone, in the Mannich reaction mainly produces one Mannich base; while the asymmetrical ketone, such as 2-pentanone, gives two Mannich bases. The reactivity depends on the tereo-hinder of both ketones and amines. 展开更多

A series of regular and irregular wave experiments are conducted to study the reflective and transmitting performances of quarter circular breakwater (QCB) in comparison with those of semi-circular breakwater (SCB). Based on regular wave tests, the reflection and transmission characteristics of QCB are analyzed and a few influencing factors are investigated. Then, the wave energy dissipation as wave passing over the breakwater is discussed based on the hydraulic coefficients of QCB and SCB. In irregular wave experiments, the reflection coefficients of QCB and their spectrums are studied. Finally, the comparisons between the experimental results and numerical simulations for QCB under regular and irregular wave conditions are presented. 展开更多
