Usually, the stability of individual commodity market price fluctuation is studied based on supply - demand equilibrium, called as " cobweb model "
通常，關于單商品市場價格波動的穩定性問題，是在供需均衡的條件下進行研究的，稱為「蛛網模型」 。 -
The dynamic change and the stability of the generalized cobweb models such as model one are studied, including setting up the models and giving the economic meanings ; dynamic analysis on model one and proving that the price array produced by model one wo n ' t emerge above the third cycle movement and chaos ; stability analysis on model one and obtaining six theorems about the stability of equilibrium price. chapter four, analysis on some specialized cobweb models. this is the second key part of the thesis
主要研究了對形如模型（ ）的一般化蛛網模型的動態分析與穩定性問題，主要包括三個方面工作：一是建立模型並給出經濟含義；二是對模型進行動態分析，證明了由模型（ ）所生成的價格系列在一定的條件下不會出現3以上周期運動和混沌現象；三是對模型進行穩定性分析，並得到模型（ ）關于均衡價格穩定的六個定理。 -
Evolution mechanism of logistic equation is studied, and is used in a kind of cobweb model. the stability and the characters are studied with the change of parameters. finally the parameters " regions in which the economic system reaches the stability and the chaos are determined
第五章：邏輯斯蒂方程在蛛網模型分析中的應用本章研究了邏輯斯蒂方程的演化機制，並將它應用在一類蛛網模型的研究中，對模型進行動態分析和穩定性分析，研究了各種參數條件下的性態，確定了經濟系統達到穩定狀態的參數范圍及進入混沌狀態的參數范圍。 -
Thirdly, similarity matrix, dissimilarity matrix or similarity table are established based on the n - strong peaks, the overlap rate of common peaks and the cosine / sine of vectors " angle which are derived from the fingerprint chromatograms of samples. and based on these data model, clustering research has been done by k - means algorithm, biggest tree in fuzzy clustering and improved cobweb algorithm, where different results have been gained. by comparing, cobweb algorithm is the best
本次研究利用n強峰、共有峰的重疊率和向量夾角正餘弦值對樣品色譜指紋圖譜分別建立了相似度矩陣、相異性矩陣或相似度表，以這些數據模型為基礎，分別用了k -平均、模糊聚類的最大樹法和改進的cobweb法進行了聚類研究，得到了不同的效果。
