  1. The calculated results show that, for low energy protons ( energy less than several decade mev ), the contribution of proton nuclear reaction to energy deposition can be neglected ; while for high energy protons ( energy greater than several hundred mev ), the great difference appears for the above two cases. this gives us an indication that the contribution of proton nuclear reaction to the energy deposition must be concerned for high - energy protons. the propagation process in material of thermal shock wave induced by high - energy intense - current pulsed proton beam irradiation is calculated for several different proton energies

    對于入射能注量為418 （ j cm ~ 2 ）脈沖寬度為0 . 1 s的矩形脈沖強流質子束，計算結果表明，由於質子束能量不同，引起的初始熱激波（ 0 . 1 s時刻的熱激波）有單峰結構，也有雙峰結構，不同能量的強流質子束引起的熱激波在傳播的過程中都會出現明顯的彈性前驅波。
  2. The shearing layer is carried by the jet and the eddy is formed because of the instability and selective amplification of shearing layer which will propagate to the downstream. as the eddy impacts the impinging wall, a wave of pressure disturbance with certain frequency is induced. this wave then propagates to the upstream with high speed, and results in the overlap and amplification of the waves when the frequencies of them are close with each other

    當前噴嘴流束中的不穩定擾動波在穿過腔內的剪切層時，剪切層對其有選擇放大作用，形成渦環結構，剪切流動中渦環與碰撞壁撞擊，在碰撞區域產生壓力擾動波並向上游反射，在上游剪切層分離處誘發新的擾動的產生，當新擾動與原擾動匹配時，射流上游就被不斷地受到周期性激勵，腔內就產生流體自激振蕩並在後噴嘴出口形成脈沖射流。
  3. Evaluation results show that the turbulence in convection zone is capable of generating enough wave energy to supply coronal energy lose due to convection and radiation

  4. And then, in the simulation of three - dimensional, the application of o - type grid and hybrid grid are used in two relatively complicated structures make the total amounts of grids and the time of grid generation reduced greatly. moreover the hexahedron grids are placed in most areas to provide higher precision. through the comparison between the results of two - dimensional and three - dimensional simulation, we knew two - dimensional calculating is not adequate

  5. ( 3 ) with the increase of the injected current, the lasing wavelength of fgesl appears fluctuation, the side mode suppression ratio ( smsr ) increases accompanied by an oscillation, and the p - i curve distorts slightly

    Fgesl的激射波長隨ld的注入電流的增大而發生波動;邊模抑制比（ smsr ）隨注入電流的增大總體上呈現上升趨勢，但其變化過程並不平滑而是有較大的波動; fgesl的p一i曲線有微小的扭曲。
  6. At the same time, the possibility of using nonlinear optics in widening the detecting wave band of hartmann - shack wavefront sensor is exploringly discussed. adaptive optics guarantees the beam quality of laser projecting system. beam cleanup, atmospheric turbulence compensation and correction of any disturbance and fabrication error in the light way are required to promise a near diffraction beam, but normal adaptive optics system can only correction one of them
