  2. Abstract : the restoration of the riparian vegetation disturbed by human activities is one of the hotspots of watershed ecology. through interpreting the images of remote sensing in 1985 and 1999, the basic information of forest resources of lushuihe forest bureau, which is a typical forest area of changbai mountain, was obtained with support of gis. by dividing land covers of lushuihe area into 10 types ( water body, residential land, stump land, farming land, wetland, mature conifer forest, midlife conifer forest, mature broadleaf forest, midlife broadleaf forest, and man - made young forest ) and dividing the riparian zone into four buffers ( in turn, 1000, 2000, 3000, 4000 m away from the river ), the changes of riparian forest resources during 1985 - 1999 were analyzed. the results showed that the deforestation intension has obviously decreased and the whole environment has been evidently improved, but the riparian ecosystem was still flimsy. in buffer 1, 2, 3, the area of midlife conifer forest increased largely, but the areas of other types of land covers all decreased. midlife conifer forest had a comparatively good status in the three buffers. in buffer 4, midlife conifer forest, mature conifer forest, and mature broadleaf forest formed a forest - age rank that is helpful to stabilize the forest ecosystem and exert its functions. area percentage of wetland decreased in buffer 1, buffer 2, and buffer 3, even in buffer 4 in which forest ecosystem rehabilitated comparatively well, so protecting and rehabilitating wetland is a very difficult task

    文摘:本文對兩期遙感圖像進行解譯,並在gis支持下提取露水河林業局主要河流兩岸各緩沖區森林資源信息,經分析得到各類地物在1985年及1999年的變化趨勢.結果表明:在河流沿岸對森林的採伐強度1999年較1985年明顯減小,整體生態環境較1985年有所改善.在緩沖區1 , 2 , 3除中齡針葉林大幅度增加外,其它地物類型均減少,由此可以看出,在這三個緩沖區內針葉林得到了較好的恢復.在緩沖區4內,中齡針葉林、成熟針葉林、成熟闊葉林形成一個林齡梯隊,有利於森林生態統的穩定與功能的發揮,十五年間緩沖區4受到的干擾相對較小.量在四個緩沖區內均有所減少,雖然在緩沖區4內森林生態統恢復的較好,但仍有所減少,說明保護及恢復地資源是一件非常艱巨的任務,必須引起高度重視.圖5表2參12

  4. The calculated drafts covers the whole possible ship draft in the large amplitude motion ; secondly, the research creates and solves the ship large amplitude motion equations. on the one hand, the actual calculation takes into account the coupling between the different motion modes, on the other hand, in the process of calculation of the ship hydrodynamic coefficient, it considers the influence of the nonlinear factor. the hydrodynamic coefficient used in the calculation of froude - krylov force, diffraction force and radiation force changes instantaneously following the draft, and the hydrostatic buoyancy is computed very accurately for the instantaneous immerse hull

    本文的研究分為二個部分:首先利用frank源匯法計算水動力,計算包括不同吃水時的附加質量和阻尼,吃水范圍涵蓋了船舶大幅度運動時所有可能的吃水;然後建立和求解船舶大幅度運動方程,在實際計算時一方考慮了運動模態之間的耦合,另一方在計算水動力時,考慮了非線性因素的影響。 froude - krylov力、輻射力、繞射力中的水動力隨吃水瞬時變化,靜浮力的計算精確到船體瞬時,最後用四階龍格?庫塔方法在時域內求解船舶運動方程,並進行了載荷計算。
  5. Water cement ratio and mixing fly ash or slag into concrete effect on ability of resisting chloride penetrating that are considered in the model. the effect of environment that include temperature, relative humidity and cumulating of surface chloride concentration of concrete are also considered. moreover, chloride diffusion changing with time is included in this model as well as

    模型中考慮水灰比和混凝土配合比(摻入不同量的粉煤灰和礦渣)變化對混凝土抵抗氯離子侵蝕能力的影響,同時考慮溫度、相對度和表氯離子濃度累變化等環境因素對氯離子侵入混凝土過程的影響,以及氯離子擴散隨時間的變化。
