  1. All the contents are developed around a set of scaling laws taking the form of exponentials which relate to almost all the issues of complexity including fractals, chaos, strange attractors, localization, and symmetry breaking, etc. the main work can be summarized as follows : starting from the law of allmetric growth three fractal dimensions in a broad sense are derived, and according to these dimensions, geographical space is divided into three levels, i. e., real space, phase space, and order space, each of which corresponds to a kind of dimension. based on the idea of spatial disaggregation and using the rmi ( relationship - mapping - reversion ) principle, the urban system is formulated as three scaling laws of the three spaces, including number law, size law, and area law, which can be transformed into a set of power laws such as allometric law and zipf ’ s law associated with fractal structure

    從異速生長的縱向、橫向和切向三個角度將地理空間劃分為實空間、相空間和序空間,分別對應于空間系列、時間序列和級序列三個層面,每個層面的測度各有自己的空間維度。基於「空間循環細分-級體系-網路結構」的數理價關系,利用rmi (關系-映射-反演)原則,成功地實現了城市系統宏觀模型的理論抽象,將空間復雜性問題表徵為簡單的指數式標度(包括數量、規模和尺度) ,這一組標度可以與一組(包括具有分形性質的規模-數目、異速生長和三參數zipf)互為變換。
  2. The study results show that the minimum ac flashover voltage decreases with the increase of the ice amount accreted on the insulator surface by an exponential law, and the down - trend of the minimum ac flashover voltage will slow gradually with the bridging of the shed of the insulators by icicles, both the average saturated ice amount and the special exponent m of effect of ice amount for different insulators depend on the radius of shed and the air - gaps of the sheds of the insulators, and that the ac ice flashover voltage decrease with the decrease pressure ratio p / p0 ( rise of the altitude ) by power - law for different esdd and icing - states when the altitude is from 4000m to 5500m. the special exponent n, which show the effects of altitude on the flashover voltage, is various with the type of insulator, icing - states and the surface status of iced insulator etc., and that the minimum ac flashover voltage of iced insulators decreases by power - law with esdd or the freezing water conductivity for different ice amount and atmospheric

    研究結果表明:在不同海拔高度和值鹽密esdd下,絕緣子的最低交流冰閃電壓均隨覆冰量的增加而呈指數規降低;當覆冰量增加到一程度后,最低交流冰閃電壓隨覆冰量增加而降低的趨勢趨于飽和;不同絕緣子串的平均飽和覆冰量及閃絡電壓的覆冰量影響特徵指數m均與絕緣子的盤徑和傘距因素有關;在海拔4000 5500m之間,不同值鹽密esdd和覆冰狀態下,絕緣子的交流冰閃電壓隨海拔高度的增加(氣壓的降低)與p / p0呈乘關系降低,氣壓影響特徵指數n與絕緣子類型、覆冰類型、覆冰表面狀況因素有關;當覆冰量和氣壓一時,絕緣子的最低冰閃電壓均隨著值鹽密( esdd )或覆冰水電導率的增加而呈乘關系降低,並逐漸趨于飽和。
