The paper is based on systematology theory and means, qualitative and quantitative analysis, statistical information analyzing. referring to many papers, historical literature, statistical data, we analyze the evolvement of rivers and lakes, and its driving forces in sihu area from holocene epoch, and discuss the interaction of its change and regional anthropogenic activities. we also systemically analyze the complexity and rules in their interrelationship. furthermore, we study the benefit and harm of the water conservancy - hardhanded driving force coming from human world
本文以系統論的思想和理論為指導，採用定性和定量相結合的方法，參照大量的文獻、歷史資料和多項統計數據，通過對四湖地區全新世以來的河湖環境演變過程及其驅動因子的分析，探討了河湖環境演變與區域人類活動的相互作用；尤其是系統地分析了區域河湖系統和人類活動之間的密切聯系、相互作用、相互制約的復雜性和特定的規律性。The results showed that the capability of reaumuria soongorica in seed actual reproduction and artificial restoration was positively correlated with disturbance levels ; the capability of restoration varied with the characteristics of disturbance factors, of which water was the key factor
結果表明，紅砂種子更新恢復能力與干擾水準呈正相關；干擾因數的特徵不同，則更新恢復能力不同；尤其水分因數參與對紅砂種群的自然更新與人工輔助恢復起著關鍵性的作用。Especially since 1990s, the increase year in and year out of quantity of floating population, " farmers " frenzied hunt for work in cities " annual tide get up tide, become will it be the end the 20th century china one of the most noticeable phenomena of the social economic life
尤其是20世紀90年代以來，流動人口的數量年復一年的增加， 「民工潮」每年潮起潮湧，成為20世紀末中國社會經濟生活中最引人矚目的現象之一。廣東作為我國改革開放的前沿陣地，是全國經濟發達的地區之一，也是全國流動人口的主要流入地之一。An efficient algorithm qais is proposed that uses the efficient method to reduce database access activity, and present a novel algorithm aiu based on this algorithm, it is fit for mining association rules and incremental updating. it is especially effective in vldb, mining long patterns, and high support. the perfermance of qais / aiu is verified on the basis of synthetic data, experiments show that the proposed algorithm can mine association rules more efficiently by not generating candidate itemsets and reducing the redundancy of frequent itemsets while generating association rules
然而目前大多數挖掘關聯規則的演算法往往必需多次掃描事務數據庫才能達到要求的目標，這樣重復性的數據庫存取動作將會導致過多的執行時問浪費在i o動作上，另外在頻繁集生成規則時現有的演算法沒有考慮到規則的大量冗餘，為了解決這個問題本文提出了一個不需要生成候選集同時有效的去除生成規則時產生大量冗餘的演算法qais ，來提高關聯規則生成的速度，並且在此演算法基礎上提出了新穎的關聯規則增量更新演算法aiu ，通過應用合成數據驗證了qais aiu演算法的有效性，由試驗結果來看這個方法確實能更有效且準確地獲得事務數據庫的關聯規則，尤其適合挖掘超大數據庫中高支持度下長模式的挖掘。A measuring technique of geometric accuracy for the cross - sectional contours based on their shapes and centroids is presented, and the feature points are generated according to the offset value of each segment of a cross - sectional contour
摘要以切層輪廓的形狀因子和幾何形心作為輪廓精度的評價參數，根據各輪廓邊的偏置量自動拾取輪廓的特徵點，尤其適合得到具有復雜形狀的切層輪廓特徵點。Especially, the relay protective settings of transmission line are greatly affected by network parameters and framework changing resulted from operational mode of system and the examining and repairing of equipment. so it makes the calculation of relay protective settings more complicated and the more repeated computation work and lasts more time, while the best plan ca n ' t always be achieved
尤其輸電線路保護整定值受系統運行方式、設備檢修等導致的網路參數和結構變化影響較大，使得其整定計算更加復雜繁瑣，重復計算工作量非常大，耗時較長，而且還不一定能夠得到最優方案。But as we add more complexity into the grid, particularly with geographically dispersed sites or nodes, it becomes more common for the job scheduler and data mover to make conflicting decisions
但是由於我們增加了網格的復雜性，尤其是那些地理上分佈的站點或節點的復雜性，因此任務調度程序和數據移動程序很可能會作出相互沖突的決定。分享友人
