A Diode laser is a kind of small solid-state laser with coupling long life. It has good characteristics of high photoelectric conversion and couples optical fiber to manufacture in material processing. Because output power was only milliwatts or less than a few watts in the early days, the range of applications was mostly in the optoelectronic and biomedical fields. In recent years, technological advances have led to diode array development and the application of diode laser power has increased to tens of watts, allowing the diode laser to branch out into the field of industrial manufacturing. The kilowatts of ultra-high power diode lasers also have long been available, making the ability to process high-profile become prominent. This paper uses a diode laser of wavelength {21244b} = 988nm, with a maximum output power of 200W. The 988nm wavelength is suitable for the laser transmission to process plastics, while 200W output of power is enough to process sheet metals. In order to understand diode laser processing capacity, we use experiment material of 304 stainless steel, 64 titanium alloy and PMMA polymers, to explore a wider range of processing capacity from diode laser. Experiment results show a thickness of 3mm or less of the 304 stainless steel can be successfully welded with full penetration. The same result is observed with the 64 titanium. As for the PMMA, diode laser show the high material removal rate from black PMMA when using the parameter conditions P/V = 0.3 that can remove depth of material to 1.5mm or more. The effects of the color of PMMA on laser transmission welding are also investigated. The experimental results show that white PMMA is not suitable for laser transmission welding. The proper range of the laser machining conditions for the red, yellow and blue PMMA are P/V = 0.3~

Combining a clear, practical and accessible style with a methodical and thorough treatment of the language, it equips learners with the essential knowledge and skills needed to communicate confidently and effectively in Chinese in a broad range of situations. No prior knowledge of the language is required. Colloquial Chinese is exceptional; each unit presents a wealth of grammatical points that are reinforced with a wide range of exercises for regular practice. A full answer key, a grammar summary, bilingual glossaries and English translations of dialogues can be found at the back, as well as transcripts of listening practice exercises. Key features include: A clear, user-friendly format designed to help learners progressively build up their speaking, listening, reading and writing skills Jargon-free, succinct and clearly structured explanations of grammar Step by step introduction of Chinese characters An extensive range of focused and dynamic supportive exercises A combination of listening, reading and speaking activities with the support of transcripts at the back of the book Realistic and entertaining dialogues covering a broad variety of narrative situations Helpful cultural points explaining the customs and features of life in China An overview of the Chinese language: its sounds, structure and Chinese characters Balanced, comprehensive and rewarding, Colloquial Chinese is an indispensable resource both for independent learners and students taking courses in Chinese as well as teachers of Chinese. Audio material to accompany the course is available to download free in MP3 format from www.routledge.com/cw/colloquials. Recorded by native speakers, the audio material features the dialogues, new words and listening practice exercises from the book and will help develop your listening and speaking skills.

This book is intended as a systemic functional contribution to language typology both for those who would like to understand and describe particular languages against the background of generalizations about a wide range of languages and also for those who would like to develop typological accounts that are based on and embody descriptions of the systems of particular languages (rather than isolated constructions). The book is a unique contribution in at least two respects. On the one hand, it is the first book based on systemic functional theory that is specifically concerned with language typology. On the other hand, the book combines the particular with the general in the description of languages: it presents comparable sketches of particular languages while at the same time identifying generalizations based on the languages described here as well as on other languages. The volume explores eight languages, covering seven language families: French, German, Pitjantjatjara, Tagalog, Telugu, Vietnamese, Chinese, and Japanese.
