And through leslie matrix analysis, we deduced, except of the subpopulation at altitude 490m, the subpopulations of lilium tsingtauense will not die out if not been disturbed badly. we estimated the growth ability and resistance ability of both metapopulation and local population by use the method of quamitative analysis for population structura1 dynamics. the growth ability order is population l > population 2 > population 3 > population 5 > population 6 > metapopulation > population 4
川叩iqu n了e ）復合種群研究摘要從種群年齡結構的穩定、衰退、增長概念出發，以種群結構參數為依據，運用加權法與條件概率乘法法則，定量椎導出衡量種群年齡結構及群落結構的動態指數，該方法克服了過去在植物種群結構動態比較評價中粗放的等級歸類劃分的缺陷，並能解決結構動態定量比較評價問題，因而認為有普遍使用的價值。Based on substitution of the indiscernibility relation by a dominance relation and a confident threshold value a set, an extension of the rough sets model is proposed, which can deal with possible inconsistencies in preferential multiple attribute decision tables and obtain preferential probabilistic decision rules made up of preference actions
摘要通過用優勢關系代替不可分辨關系，並設定置信閾值，提出了一種可以從偏好多屬性決策表中發現偏好概率規則集的擴展粗糙集模型。The problem of signal processing for direct - sequence code - division - multiple - access ( ds - cdma ) signal over multipath frequency - selective mobile channels is considered. a new blind receiver is proposed. without the knowledge of the multiple - access interference users spreading code and the channel characteristics, the receiver achieves blind detection with prior knowledge of only the desired users spreading code and approximate timing. by using reduced rank adaptive decorrelating filter and adaptive multipath combiner which is based on decision - directed algorithm, the receiver gets the ability to combat both fading and the near - far effect at low cost. simulation results demonstrate that the proposed receiver offers high performance
本文研究多徑頻率選擇性衰落通道下直接序列擴頻碼分多址（ ds - cdma ）信號的處理問題，提出了一種新型的盲接收機.該接收機不需預知多址干擾用戶的擴頻碼，不需預知通道參數，只需已知期望用戶的擴頻碼和粗略的定時，就可以完成用戶的盲檢測.同時，該接收機通過降維自適應去相關濾波和基於判決指導的自適應多徑合併，來獲得低成本和良好的抗衰落、抗遠近效應性能.模擬結果驗證了本文提出的接收機的優良性能
