Recent progress in ultrafast optics has allowed the generation of ulfcraintense light pulses comprising merely a few field oscillation cycles. the arising intensity gradient allows electrons to survive in their bound atomic state up to external field strengths many times higher than the binding coulomb field and gives rise to ion - ization rates comparable to the light frequency resulting in a significant extension of the frontiers of nonlinear optics and ( nonrelativistic ) high field physics
隨著超快光學技術的發展,僅含幾個振蕩周期的超強脈沖已經能產生,且其強度梯度可使電子存在比庫侖束縛場高許多倍的外場產生的原子束縛態上,並產生了同光頻相差不大的電離率,從而促進了非線性光學前沿及非相對論的強場物理的延伸。It also analyses and compares the characteristics of bulk acoustic wave and surface acoustic wave, such as directivities and shapes. and then optical detection methods of laser - induced ultrasonic, especially cfpi detection method, are introduced
然後,介紹了激光超聲的光學檢測技術,並重點分析了外差干涉檢測技術和共焦fabry - perot干涉檢測技術的原理和特點。The suitable preparing condition of the composite has been set down by a series of experiments. the clay / poly - acrylamid superabsorbent composite is characterized by infrared ( ir ), thermogravimetry, analysis ( tga ), differential scanning, calorimetry ( dsc ) and x - ray diffraction analysis ( xrd )
