It is shown that the average [O] in the steel can be decreased to 12.86 ppm and there is an optimal [%Si] at the end of melting as 0.11%, at which [O] after vacuum carbon deoxidation （VCD） is minimum. A kinetical model has been deduced to simulate the VCD process. The results show that adding Si before Al is superior to the adding Al before Si with respect to the final [O] in the steel. It is suggested that the melting point of covering slag should be lower than 1550℃, and （FeO+MnO） should be less than 1%, so as to effectively refine GCr15 steel

• Ⅰ. Amplification in English-Chinese translation • Amplification means to add necessary words, phrases, clauses or sentences to the translated text in purpose of making it consistent with the target language in meaning, grammar and culture connotation. Amplification does not add new information to the message and only help understand the text. In this part we will analyze how to use amplification to achieve equivalence in English-Chinese translation in these three levels, i.e. syntactic, semantic, and rhetorical. • 1) Her tone was more friendly than David’s (tone). • 2) She sang her sweetest (song). • 3) Shall I write my name on, above or below the line?

This is the first book that can be considered a textbook on thin film science, complete with exercises at the end of each chapter. Ohring has contributed many highly regarded reference books to the AP list, including Reliability and Failure of Electronic Materials and the Engineering Science of Thin Films. The knowledge base is intended for science and engineering students in advanced undergraduate or first-year graduate level courses on thin films and scientists and engineers who are entering or require an overview of the field. Since 1992, when the book was first published, the field of thin films has expanded tremendously, especially with regard to technological applications. The second edition will bring the book up-to-date with regard to these advances. Most chapters have been greatly updated, and several new chapters have been added

Need to study structural mechanics to design properly to prevent failure There is no doubt that any of the disciplines of Aeronautics and Astronautics can contribute to an accident -engine failure -etc. But, the vast majority of non-human induced accidents is due to structural

Teaching Objectives: Students(Ss)will be able to: get acquainted with a new way of communication-showing deep caring to others. understand the favorable effect of deep caring and learn how to extend a helping hand to people in difficulties

Fuzzy control does not exist as an isolated topic devoid of relationships to other fields, and it is important to understand how it relates to these other fields in order to strengthen your understanding of it. We have emphasized that fuzzy control has its foundations in conventional control and that there are many relationships to techniques, ideas, and methodologi there. Fuzzy control is also an\intelligent control\technique

Acute(急性) and chronic(慢性) toxicity Acute toxicity refers to a rapid and serious response to a high but short-lived dose Acute poisons interfere with essential physiological processes, leading to a variety symptoms of distress, even death Chronic toxicity refers to a time-lagged response to a relatively low but prolonged exposure

Persons freedom to communicate, and their ability to do so effectively, has long been recognized as a crucial component of a society that respects human dignity and provides the conditions for humans to flourish. Government actions that suppress persons'speech and other forms of communication have been rightly subject to scrutiny and challenge Governments have also recognized the importance of affirmative steps to enhance persons opportunities for communications, such steps include improving education and supporting public forums. Communication is not only a personal and political good

Static stability is all about the initial tendency of a body to return to its equilibrium state after being disturbed To have a statically stable equilibrium point, the vehicle must develop a restoring force/ moment to bring it back to the eq. condition Later on we will also deal with dynamic stability, which is concerned with the time history of the motion after the disturbance

itrogen-containing compounds are essential to life. Their ultimate source is atmo- spheric nitrogen which, by a process known as nitroge. nitrogen fixation, is reduce ced to ammonia, then converted to organic nitrogen compounds. This chapter describes the chemistry of amines, organic derivatives of ammonia. Alkylamines have their nitro- gen attached to sp'-hybridized carbon; arylamines have their nitrogen attached to an sp2-hybridized carbon of a benzene or benzene-like ring
