Acoustooptic extension of the frequency tunability of CW CO2 lasers: New FIR lasers emissions from CH3OH and13CH3OH

We have increased the frequency tunability of our CW waveguide CO₂ lasers by means of an acoustooptic amplitude modulator, operating at the fixed frequency of 90 MHz. The up-shifted, or down-shifted, laser optical sideband can be generated independently by adjusting the orientation of the modulator. The efficiency is larger than 50%. The frequency tunability of the CO₂ laser around each laser line is thus increased by 180 MHz. To demonstrate the possibilities of this method, a source composed of the above modulator and of a CW, 300 MHz tunable waveguide CO₂ laser has been used for the search of new large offset FIR laser lines from optically pumped CH₃OH and¹³CH₃OH molecules. As a result 15 and 10 new large offset laser lines were discovered respectively. New assignments of some laser lines are also proposed. We have also measured the Stark effect, the offset, and the polarization of other already known lines. In particular a Stark effect frequency tuning of about 1 GHz is demonstrated for a laser line at 208.399 m.     

Optoacoustic Laser Stark spectroscopy and FIR laser action on CH3Br using a waveguide CO2 laser

The optoacoustic spectrum of CH₃Br around 10 m band lines of a tunable cw waveguide CO₂ laser is investigated. Several new infrared absorptions are observed and most of the correspond ing molecular transitions are assigned. Far infra red laser action is reported by pumping with the same CO₂ laser: pump offsets are given using the Transferred Lambs dip (TLD) technique. A new FIR laser emission is obtained and assigned. An optoacoustic Laser Stark spectroscopy technique is used to investigate off resonance infrared tran sitions.     

从硅谷的成功看产学研合作中大学与科技园的关系

大学科技园是产学研合作的重要载体，对加速高校科技成果转化为生产力，促进产、学、研相结合，增强大学自我发展能力，提高办学效益发挥了重要的作用。众所周知，美国的硅谷是大学科技园的成功典范。本文拟从斯坦福大学与硅谷的关系分析，对比我国大学产学研合作中的实际做法，得出一些在高新技术产业化进程中可供借鉴的方法。     

市场化年代的格非先锋历史小说

格非注重历史在小说世界中的想象性实现,他的小说大都可以纳入先锋历史小说的范畴。格非在悲剧中反思历史,在虚构中呈现真实,在隐喻中超越现实,试图展示生命深处的人性本质。格非在历史中探求人性升华的可能,在苦难中寄寓精神救赎的希望,这种对历史和生命的终极关怀,启迪着我们去追寻遥远精神家园。格非先锋历史小说所体现的批判精神和诗性品质是文学在市场化年代应该坚守的立场。     

论"初期白话三诗人"对新诗的贡献

胡适、沈尹默、刘半农,是中国现代文学史上最早从事新诗创作并发表诗作的诗人,可称为“初期白话三诗人”。在中国现代新诗的草创期,“初期白话三诗人”的新诗理论和新诗创作都是很有探索意义的,对现代白话新诗的发展作出了不可磨灭的贡献。     

浅论新型师生关系的建构

随着素质教育的不断推进和深化，建立新型的师生关系在教学改革中显得尤为重要。通过师生相互沟通使学生参与教学决策，通过了解学生需求以融合师生感情并增强学生的主体意识，从而在更高的层次上激发学生参与教学活动和教学管理的积极性、主动性，使学生能够开放思维的空间，激发创新灵感，并真正成为学习的主人。

论民国新儒家的政治合作化与现代化构建

民国新儒家认为政治现代化要通过合作化走和平建设之路,要先利用合作化帮助劳动阶级实现经济自助,培育和锻炼下层民众,再以合作化逐步改造资产阶级,调和阶级关系,最后以合作实现他们的理想政治王国。这是一个完整的政治构想,表达了儒家精神传统的济世情怀与对中国政治的国情思考,是西方合作文化在东方地域移植的必然结果。
