  2. ( 三 ) under the dynamic load of the explosion, the numeric analysis has been done and achieve the rule as follow : ( 1 ) when the frequency of vibration is 0. 3hz, the acceleration of the slopes top gets the maximum ; so 0. 3hz is believed the natural frequency of the slope as a whole ; ( 2 ) the vibration of explosion can been magnified because of the condition of the landform, when the relative altitude is up to 45m, the acceleration of horizon gets the maximum ; when the relative altitude is up to 100m, the absolute value of acceleration and the deformation of horizon is larger than that in the bottom of the slope ; ( 3 ) in the period of forced vibration, at the top of the slope, the acceleration of horizon become larger and larger ; at the middle part of the slope, it becomes smaller ; ( 4 ) when the explosion velocity of is much little, the shallow part destruction is the primary deformation of the slope

    (三)採用模態疊加針對爆破動力作用,進行邊坡的動力響應分析,得出了以下結論: ( 1 )振動頻率為0 . 3hz時,坡面頂部水平向加速度最大;綜合考慮,可認為該邊坡的自振頻率為0 . 3hz左右; ( 2 )地形對爆破地振動存在放大作用,研究剖面的坡面,水平向加速度及位移在地形相對高差45米左右最大,而後隨相對高差的增高而減小,相對高差為100米時,水平向位移及加速度絕對均大於坡腳; ( 3 )迫振動段,水平向加速度隨時間變的規律為:坡頂節點總的變趨勢是越來越大,而坡體中部節點的變趨勢是越來越小; ( 4 )當爆破振速較小時,變形破壞的形式表現為坡頂表面滑塌型。
  3. Using the variational method, analytical conditions for stationary pulse propagation in dense period fibers with strong dispersion management are deduced. the expression of initial soliton peak power is given. by employing the obtained formulas, the soliton evolution semi - analytically in various dispersion maps can be investigated. effects of the third order dispersion are also studied in this paper. the results show that imperfect dispersion slope compensation can cause pulse central position shift and even serious degradation of soliton shape

    利用變分方,推導出了在色散管理的密集周期光纖中脈沖穩態傳輸的解析條件,並給出了初始脈沖功率的表達式.運用這些公式,對各種色散管理系統中孤子的演進行了半解析的考察.三階色散也被考慮在內.結果表明:不完善的色散斜率補償將導致脈沖中心位置的偏移甚至嚴重的孤子形狀劣
  4. Peg and superfluous aa reaction by complete concatenation method, the esterify production " esterify water " and acid number were mensurated, it shows that the esterify reaction would be processed under 100 esterify temperature and with amine accelerantthe tide of esterify reaction was substantiated by ir. in the ir spectrum, the characteristic peak of hydroxy of peg and carboxyl of aa were weakened. and the ester link of peg was reinforce. the " esterify water " was increased gradually and the acid number of esterify production was debased gradually along with the extent of esterify time and the augmentation of molecular weight of peg

    通過聚乙二醇與過量的丙烯酸採用全連續進行反應,測定酯產物「酯水」和酸等宏觀手段反映出在胺類促進劑、 100的酯溫度等條件下的酯進程,而利用紅外光譜( ir )分析所反映的聚乙二醇的羥基和丙烯酸的羧基特徵減弱,而pea的酯基特徵等特徵進一步證實了宏觀手段所表現出來的酯趨勢:隨著酯時間的延長和聚乙二醇分子量的增大,產生的「酯水」逐漸增加,酯產物的酸逐漸降低;從酯時間看,當反應時間達到300min時,酯物的酸達到最小,而從ir分析來看,酯物pea4的羥基在300min時減弱到最小, pea23在120min時羥基的表現出酯基本完全。
