The effects of dissolution the η′ phase by solution treatment on mechanical properties A7075-T6 alloy were investigated. Immediately after T6 sheet at 450 oC or higher, elongation significantly increased and occurred. is main hardening phase. After natural-aging, GPI, which coherent with aluminum matrix, was formed strength increased. When bake natural-aging performed, yield slightly due to par...

This paper presents our Chinese microblog sentiment classification (CMSC) system in the Topic-Based Chinese Message Polarity Classification task of SIGHAN-8 Bake-Off. Given a message from Chinese Weibo platform and a topic, our system is designed to classify whether the message is of positive, negative, or neutral sentiment towards the given topic. Due to the difficulties like the out-ofvocabul...

The CIPS-SIGHAN 2012 Chinese Named Entity Recognition and Disambiguation (NERD) bake-off was held in the summer of 2012. Named entity recognition and disambiguation is an important task in natural language processing and knowledge base construction. It aims at detecting entity mentions in raw text, followed by pointing the detected mentions to real world entities. Often, real world entities can...

The effects of copper on the ageing precipitation behavior of as-quenched and pre-aged AA6016 aluminum alloy were studied by differential scanning calorimetry (DSC), Vickers hardness measurement and transmission electronic microscopy (TEM). The results indicate that the addition of copper facilitates the growth of clusters (GP I) to the critical size during pre-ageing. Therefore, the addition o...
