However, the models in these tools lack of flexibility and are not open to the end-user. Models developed in one tool can not be conveniently used in others because of the barriers among these simulators. In order to solve those problems, a flexible and extensible distillation system model library is constructed in this study, based on the Modelica and Modelica-supported platform MWorks, by the object-oriented technology and level progressive modeling strategy. It supports the reuse of knowledge on different granularities: physical phenomenon, unit model and system model. It is also an interface-friendly, accurate, fast PC-based and easily reusable simulation tool, which enables end-user to customize and extend the framework to add new functionality or adapt the simulation behavior as required. It also allows new models to be composed programmatically or graphically to form more complex models by invoking the existing components. A conventional air distillation column model is built and calculated using the library, and the results agree well with that simulated in Anen Plus.展开更多

Based on the psychological theory of memory mechanism, the linguistic theory of lexical approach, together with the analysis of students' compositions, the author argues that writing through language chunks is effective and practicable. Methods in implementing language chunks in writing are provided as an important part in this paper.展开更多

Traditional phraseological perspective focuses on syntactic and semantic aspects of chunks and its most important criteria of chunk identifications and classifications are compositionality and frozenness/fixedness. Psycholinguistic perspective focuses on the psychological salience of chunks and its most important criterion of identifying a chunk is whether it is processed as a whole unit. Corpus linguistic perspective focuses on frequencies of chunks and its identification of chunks is done on the basis of frequency counts. All of the three perspectives have tapped into the phenomenon of multi-word combinations and yielded fruitful findings on the use of chunks in aspects of quantitative, syntactic, semantic, functional, and psychological features; however, each has their pros and cons展开更多

There are a lot of language chunks in block is different from the special language unit words, phrases, sentences, prefabricated resistance, can be stored as a whole and extract which plays important role in language acquisition. Teaching Chinese as a foreign language, the theory of lexical chunks in such aspects as help memorization and build up your language sense showed a huge advantage. To explore the teaching methods of lexical chunks has important significance to improve the effectiveness of Chinese teaching. Our research proposed the novel paradigm for the education which will be meanin~,ful and helnful.展开更多

In our Autonomous Learning Modules (ALMS) at Helsinki University Language Centre, students write various autobiographical texts as part of their language portfolios. The texts are discussed in the face-to-face counseling meetings. Finnish students' learner identities are influenced by the competitive role of English in Finland: mastering English is a must, and not mastering English can single them out as failures. This is especially true of self-identified "different" learners whose previous language learning experiences and classroom situations have caused them anxiety. In ALMS, counselors engage them in sharing stories about past learning experiences as a way of supporting them in planning their personal study programs. Storytelling also helps them to explore their "wounded" learner identities by creating safe spaces for reflexive self- study. The practice and research of such storytelling are explored in the article.展开更多

文摘For modeling and simulation of distillation process, there are lots of special purpose simulators along with their model libraries, such as Aspen Plus and HYSYS.
