  3. Besides, scan rate and cycle period also affect the result ; co - deposition of dualistic oxide is a focus of research, as an element in the same group, ir is selected. deposition rate of composition is decreased by the adding of ir composition, and when the proportion of ir exceeded 50 %, composition procession can be ceased. but cooperation of ir and ru oxide can highly increase the specific capacitance of active material ; annealing treatment under a certain temperature can help to change the hydrate ru composition into mixture state ru oxide, accordingly increase the stabilization of active material

    研究表明:電解液的配製過程中,氯化釕濃、溶液ph值、陳化時間、溶液溫對電鍍效果均有影響,其中溶液ph值是最主要的影響因素;在儀器的使用條件探索中,理論結合實驗確定了本電鍍液體系循環伏安電勢窗的理想范圍,並發現循環伏安掃描和掃描周期對電鍍結果也有較大影響;混合氧化物的共沉澱是目前研究熱點,在此選用與釕同一族的銥作為共沉澱元素,銥的加入會阻礙氧化物的沉積,銥的比例超過50 %會使沉積作用停止,但是二元氧化物的協同作用使沉積的活性物質比容量大大提高;一定溫退火后處理作用會使合釕化物轉變成混合價態的氧化釕,從而提高活性物質的穩定性。
  4. 3. aiming at the limitation of simulated anneal genetic algorithm on a high computation while applied to flow shop scheduling problems, the paper presented selected simulated anneal genetic algorithm

    人為活動干擾,如過放牧壓實土壤和去除地表覆被造成土壤滲透性顯著降低,是林地土壤質量退化及土壤分缺乏的重要誘因。試驗結果表明,植物生物量和生產力隨土壤滲透率的增大而顯著提高。
  8. Karst ecosystem is a kind of vulnerable ecosystem, its vulnerability including mainly : 1 environment capacity is small, vegetation is difficult to recover after having been destructed, hydrologic movement is rapid and floods and droughts often occur ; 2 vegetation growth depends on the conditions of eco - environment overly, which are affected by environment obviously ; 3the positive evolve of eco - environment relies on the recover of vegetation, 4the methods of water resource use and land use lack of rationality. these vulnerabilities are be magnified by climate changes

    巖溶生態系統是一種脆弱的生態系統,它的脆弱性主要表現在:環境容量小,植被遭破壞后很長時間才能恢復,以及文過程變化迅,旱澇時常發生;植被生長過依賴于生境條件,但生境條件受到環境影響明顯;生態環境的良性演化依賴植被的恢復;資源利用與土地利用方式間缺乏合理性,如刀耕火種、過渡開墾造成生態環境中種子庫嚴重丟失,物種多樣性受到影響,植被演化趨于單一或種群退化。
