  1. The characteristics of damping shows that the uncompensated parallel ac transmission line can release the coupling between the hvdc and generator and improve the damping of the system, hence the possibility of subsynchronous oscillation decrease. in such a system scheme, the hvdc system dominates the changes of damping due to the small magnitude of the damping provided by ac line. when the ac transmission line is compensated with a fixed series capacitor, the situation will be totally different

    其中，並列運行的無串補交流輸電線路可以緩解hvdc與其臨近機組之間的機電耦合程度，改善hvdc的電氣負阻尼特性，從浙江大學博士學位論文摘要而減輕機組發生次同步振蕩的危險性，此時系統的整體電氣阻尼特性由hvdc的性質決定;但若交流線路中存在串聯補償電容，則系統幅值較大的電氣負阻尼不僅可能使整流站機組發生次同步振蕩，逆變站附近機組同樣存在發生次同步振蕩的可能性，此時系統的整體阻尼特性由串聯補償電容的性質決定。
  2. In the section of theory, we mainly studied optical parameter effect, discussed physical mechanism of optical parameter laser and normalized coupled wave equation and got the solution. we also carried out the analysis of gain mode of optical parameter oscillation, studied the threshold condition, analyzed output characteristics and then achieved characteristic curve

    本文理論部分主要作了有關光參量效應方面的研究，探討了光參量振蕩器的物理機制、參量振蕩的歸一化耦合波方程，求解得到了參量振蕩器的耦合波函數，同時對光參量振蕩的增益模式進行了分析，研究了使參量振蕩的閾值條件，並對光參量振蕩器的輸出特性進行了分析，得到了特性曲線。
  3. The calculation of the position of the shocks for the domain decomposition of the hyperbolic approximation is discussed. it is the matching stable problem for the different schemes in the different domains with different mesh size. after tracing the position of the shocks, the artificial compression method are applied to eliminate the smearing effect and to raise the resolution of the schemes. in the boundaries of each regions, the universal connected matching stable schemes are inserted in so as to make the schemes between different regions matching stable each other. at last, some numerical examples are presented

    討論在激波計算中的區域分解法，即在不同區域中應用不同網格及格式的耦合穩定性問題.先定出激波位置，再在激波附近小范圍內，用低階格式及人工壓縮方法以消除彌散效應.在激波區域外，應用高精度格式，減少了過超振蕩現象，提高了解析度.在各區域交界應用全能穩定聯接格式，解決了格式的耦合穩定問題.最後舉出數值計算實例，計算結果與理論分析符合
  4. Interface capturing method for multi - fluid flow, which smear out the tangential discontinuity, is developed to simulate the compressible flow. the multi - fluid problems can be transformed to a single - fluid to resolve, using the fluid dynamic conservative equations coupled with the interfaces capturing equations, and any of stability and non - oscillation scheme for the whole computational region. the two schemes mentioned above are better

    給出的方法具有以下特點：引入界面捕捉方程將切向間斷抹平，形式上將多流體計算轉化為單一流體計算，數值計算通過解流體動力學和界面捕捉耦合方程組來實現，可以應用的差分格式是任何一種穩定和不產生非物理振蕩現象的差分格式，前面提到的兩種格式只是其中效果比較好的格式。
