    按照氣候帶的劃分，澳大利亞的北部為熱帶，中部為遼闊的乾旱地帶，南部為溫帶。澳洲的氣候比較溫和，全年溫差不大。澳洲的四季正好與中國相反。
  3. In this paper, the upwind scheme and the central scheme are presented for solving 3 - d n - s equations using the cell - center finite volume spatial discretization and four - stage runge - kutta time stepping scheme, with standard convergence acceleration techniques such as local time stepping and implicit residual smoothing

    在n - s方程的數值計算上，採用了中心差分格式和迎風格式，用格心格式的有限體積法進行了空間離散，用四步龍格?庫塔法作顯式時間推進，並採用了當地時間步長和隱式殘差光順等加速收斂措施。
  4. With the merits of technical simplicity, better adaptability to materials, less start time and operational stability, this gasification technology can produce mcv ( > 2500kcal / nm3 ) biomass fuel gas with low tar content ( < 50mg / m3 ), which entirely meets the standard of agricultural ministry ny / t443 - 2001 ? technical specification and acceptance of standard for straw gasification system of central gas supply

    其技術簡單、原料適應性好、啟動速度快、運行穩定，產出的生物質煤氣熱值2500kcal nm ~ 3 ，焦油含量50mg m ~ 3 ，均達到農業部標準ny t443 - 2001 《秸稈氣化供氣系統技術條件及驗收規范》的要求。
  5. First, the standard errors computed under the assumptionthat the error term is independent identical distribution will be biased. second, theassumption of independence is unlikely to satisfied. in the panel data analysis modelwith hierarchical structure, hierarchical effects, nested effects, time effects are seted. then the dissertation deduced parameter estimation and hypothesis test statistic andits probability distribution and analyze the hierarchical panel data set : eastern china, central china and western china are the top level, and the prc ’ s province, cities, and autonomous regions are bottom level

    然後針對目前面板數據分析過程中存在的兩方面問題，即一方面在利用面板數據模型進行分析時，標準誤差的計算是基於誤差項相互獨立並且同分佈的假設，如果誤差項是相關的將會造成估計有偏的後果;另一方面關于獨立性這一假設本身就難以滿足;提出多層嵌套面板數據模型，設定了層效應、嵌套效應以及時間效應參數，研究了多層嵌套模型的參數估計量和假設檢驗統計量及其分佈。
