  1. Base on the data collected from the field investigations, we analyzed the static life table, age structure, spatial distribution patterns of the populations of e. chloranthoides. we further studied the intraspecific competitions within the species and the interspecific competitions between the species and other concomitant species in the communities. with the helps of the logistic equation, leslie ' s matrix and the average moving law method we simulated and estimated the population dynamics of this endangered plant species

    本研究以縉雲衛矛為研究對象，通過對三個種群的野外調查，研究和分析了縉雲衛矛的種群年齡結構、種群空間分佈格局及種內和種間的競爭關系，並利用logistic方程、 leslie矩陣及移動平均法模擬和預測了三個種群的數量和結構動態，在此基礎上分析了造成縉雲衛矛瀕危的原因，提出了相應的保護措施，旨在為縉雲衛矛的保護提供理論依據。
  2. After a short - term load forecasting method based analogous and linear extrapolation is proposed, the load forecast and the priority of equipment action are led into static reactive power optimization. the aim function is constructed for the practical situation of power system. on the basis of traditional genetic algorithm the fitness function and the holding of population diversity are improved

    在提出基於相似日和線性外推的短期負荷預測新方法的基礎上，將負荷預測和設備動作優先級引入靜態無功優化中，並結合電網實際情況，構造了實用的目標函數，對遺傳演算法的適應度函數和群體多樣性的保持進行了改進，採用鄰域搜索運算元增加遺傳演算法的局部尋優能力。
  3. Sql server will consider parallel execution plans for queries, index data definition language operations, and static and keyset - driven cursor population

    Sql server將考慮為查詢、索引數據定義語言（ ddl ）操作、靜態的和由鍵集驅動的游標填充實施并行執行計劃。
  4. A static cge model is constructed and applied to simulate the aging population problem and analyze it in contrast between 2000 and 2050

    本文建造了一個靜態cge模型，採用比較靜態分析的方法，對人口老齡化的問題進行了實證模擬。
