This thesis was divided into eight chapters, and the main results and innovations obtained here can be summarized as follows : ( 1 ) the physics model of tsrs in frequency conversion crystals has been built up firstly. based on quantum - mechanical viewpoints and the following physical processes and parameters : the two - photo interaction of light with matter, paraxial diffraction of stokes, langevin noise sources, reflection at the faces and the edges of crystals, gain coefficient, beam aperture, pulse width and fluence of 3, the physics model of tsrs in kdp and kdp crystals acting as high - fluence frequency convector and the paraxial operator maxwell - bloch - langevin equations have been built up
全文共分八章，取得的主要成果及創新點如下： （ 1 ）首次建立了諧波轉換晶體的tsrs物理模型本文根據量子力學原理，在考慮如下物理過程和參量的基礎上：光與物質的雙光子相互作用； stokes光的傍軸衍射； langevin （郎茲萬）噪聲源；晶體表面反射和端面反射；增益系數、光束口徑、脈寬和三倍頻光能量密度，推導出高通量激光在kdp和kd ~ * p諧波轉換晶體中的tsrs物理模型和空間上的近軸算符maxwell - bloch - langevin方程組。The presence of microwave or ultrasonic wave, the inter - and intra - molecular complexation of cellulose molecules through hydrogen bonding is weakened, and the complexed polymer of cellulose and nylon formed in situ. the yield strength and young ' s modulus of the ramie / nylon / lldpe composites are increased from 9. 68 mpa, 260 mpa to 15. 7 mpa and 722 mpa respectively
經微波輻照或超聲波處理后，苎麻纖維素氫鍵被削弱，與尼龍形成氫鍵復合物，增強了苎麻尼龍電子束輻照lldpe復合材料體系的相容性，屈服強度、楊氏模量從9 . 68mpa 、 260mpa提高到15 . 7mpa 、 722mpa 。
