  1. The systematic and synthetic description and review of lianas, chiefly in tropic, are described and reviewed in this paper, in which some ecological questions of lianas are included distributed as follows : ( 1 ) the conception and significances of lianas ; ( 2 ) liana flora and its distribution in the world ; ( 3 ) its biological characteristics ; ( 4 ) its ecological characteristics ; ( 5 ) its abundance ( density ) and species - richness in tropical forest ; ( 6 ) the ecological significance of lianas - aggregation in gap and the variance of its abundance in the process of forest succession ; ( 7 ) the relationship between lianas and trees ; ( 8 ) the positive and the negative contribution of lianas to tropical forest ; ( 9 ) the types of climbing mechanism of lianas and its competitive predominance ; ( 10 ) global climate - variance ( co2 increase ) promotes abundance of lianas to increase, and some ecological consequence are resulted from which

    摘要對藤本植物（以熱帶為主）研究的動態與發展進行了綜述，其中包括： （ 1 ）藤本植物的概念及重要性； （ 2 ）藤本植物區系和分佈； （ 3 ）藤本植物的生物學特性； （ 4 ）藤本植物的生態學特性； （ 5 ）藤本在森林中的多度（密度）及種的豐富度； （ 6 ）藤本在空地上聚生的生態意義以及它們在森林演進過程中的消長； （ 7 ）藤本與樹木的相互關系； （ 8 ）藤本對森林正面和負面的影響； （ 9 ）藤本的攀援方式類別及其競爭優勢； （ 10 ）全球氣候變化（ co2濃度增高）促進藤本優勢度增長並導致不良的生態後果。
  2. The particles aggregation was simulated using particle - cluster and cluster - cluster aggregation model. several type of floes was reached and its morphological characteristics was analyzed the fractal dimension, density and porosity of floes was studied by changing sticking probabilities, sticking position, particle number, particle concentration, difrusion coefficient and motion trajectory. the parameters by which special floes growth were determined. in the study of morphology, floes of yellow river ' s loess particles was observed by tv - microscope. its morphological characteristics were obtained by image analysis. the effect of fractal dimensions by stirring time strring speed, macromolecule flocculant dosage, flocculant concentration and particle concentration was studie. its rule of change was obtained. on the basis of other studies, the flocculation kinetics and floes structure was studied

    本文應用計算機模擬技術，在二維空間內採用單體凝聚和集團? ?集團凝聚兩種模型對顆粒凝聚過程進行了模擬，得到了多種形態的絮體，並對絮體進行了形態分析，通過改變粘附概率、粘附位置、顆粒數量、顆粒濃度、擴散系數和運動路徑等模擬參數，我們考察了絮體分形維數、密度和孔隙率隨模擬條件變化的影響規律，得到了形成特定形態絮體的控制參數。
  3. The mangrove bushes of 0. 26 acres located along the coast of keya river, adjacent to the exit of the west coastal expressway is an aggregation of many organisms in high density

    位於虎山裡西濱快速道路下，客雅溪沿岸旁，有一片面積0 . 26公頃的水筆仔純林，是許多生物聚集點，生物的密度非常高。
  4. Ca2 + ions from the reactants attended to be absorbed in the diffusion dilayer by the so3 - anion. calcium ions could compress the diffusion dilayer and reduce the aggregation number of aot molecular because of the higher charge density. the absorbance of ca2 + ions change of phase diagram of system and water core diameter

    反應試劑溶液中的ca ~ （ 2 + ）離子傾向于被吸附在aot極性頭基的- so _ 3 ~ -陰離子附近，壓縮了極性頭基水解產生的擴散雙電層，使得aot分子的聚集體變小，也使得處于束縛狀態的水分子數量減少。
