Hummel promises to deploy the missiles over san francisco if washington doesn t make amends to ignored combat victims to the tune of 100 million. a cadre of navy seals are dispatched to quell the situation, assisted by the mysterious, macho john mason sean connery, the only man to ever escape from alcatraz, who must now help the seals break back in
當時間一分一秒地溜走的同時，苦無對策的政府只可依靠一位件輕的化學武器專家尼古拉斯基治飾及唯一一個曾逃離石牢的聯邦要犯辛康納利飾勇闖墜壘，拆毀所有毒氣飛彈，以解除這個危困。Femtochemistry and organic reaction mechanism
飛秒化學與有機反應歷程The 1999 nobel prize in chemistry was rewarded for professor ahmed h. zewail, california institute of technology, pasadena, usa for his studied of the transition states of chemical reaction using femtosecond spectroscopy. his pioneering investigation of fundamental chemical reactions, using ultra - short laser flashes, on the time - scale on which the reactions actually occur, and the development of femtochemistry are introduced
介紹了1999年諾貝爾化學獎得主哈邁德.澤維爾教授採用激光技術研究超快化學反應，特別是對飛秒化學所作的先驅性研究以及飛秒化學的產生與發展。With the development of science and technology, more and more oxide crystals are synthesized by more and more advanced technique, the new oxide crystals are incessantly synthesized and the new characters of oxide crystals are incessantly founded. corundum dopped with impurity not only is cherished because of it ' s beautiful appearance, but also is used in the fields such as electrotechnics, mechanism, laser, the optic apparatus and the underlay of semiconductor. sapphire dopped with ti3 + is the best material of the tunable solid laser. zno crystal is material of the direct gap semiconductor ( the width of forbidden band : 3. 37ev ). the excited emission in zno crystal at room temperature has been found, so the ultraviolet luminescence in zno semiconductor can be acquired at room temperature
含有少量雜質的剛玉晶體（ - al _ 2o _ 3 ）不僅由於其色澤艷麗成為人們珍愛的名貴寶石，而且由於它具有的優異性能，被廣泛應用於電工、機械、激光器，光學器件和半導體襯底材料。鈦藍寶石是目前最優異的固體寬帶調諧激光材料，用於製作飛秒脈沖可調諧激光器。氧化鋅晶體是直接帶隙寬禁帶半導體材料（禁帶寬度3 . 37ev ） ，現已發現具有室溫下受激發射特性，有可能實現室溫下半導體紫外發光。We use the laser output ( 320 nm, 200 fs ) of optical parametric amplifier ( opa ) in < wp = 5 > an active passive mode - locked femtosecond ti - sapphire laser operating at a repetition rate of 1khz as a exciting resource to develop optically pumped stimulated emission of zno thin films. when rectangular stripe laser irradiates thin films, optical resonant cavity is naturally formed between two nanocrystallites along with the rectangular laser stripe and planar weveguide confines the light scattering
利用飛秒激光器作為光泵浦激發光源，研究了氧化鋅薄膜的光泵浦受激發射，當條形光斑輻照薄膜樣品時，將沿著光斑條由氧化鋅納米晶面自然地形成光學諧振腔，由於平面介質波導結構限制光散射，所以成功地觀測到二氧化硅襯底上的納米氧化鋅（ zno ）薄膜的紫外受激發射。分享友人
