    結果表明，不管是懸浮物截留、吸附，還是微生物的生長，所造成的堵塞狀況都呈現出隨濾層厚度增加按負指數形式遞減的趨勢。
  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：在不同海拔高度和等值鹽密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律降低；當覆冰量增加到一定程度后，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等因素有關；在海拔4000 5500m之間，不同等值鹽密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呈乘冪關系降低，氣壓影響特徵指數n與絕緣子類型、覆冰類型、覆冰表面狀況等因素有關；當覆冰量和氣壓一定時，絕緣子的最低冰閃電壓均隨著等值鹽密（ esdd ）或覆冰水電導率的增加而呈乘冪關系降低，並逐漸趨于飽和。
  3. To solve the problem of exponential space in the instruction - set automated design for the application specific instruction set processor ( asip ), a formular clustering integer linear programming model ( cim ) is proposed, which can decrease the exploration space effectively utilizing function dependencies between instructions

    摘要提出集束式整數線性規劃形式化模型，利用指令間的功能依賴性解決專用指令集處理器中指令集自動定製的指數性空間問題。
  4. The test results show that both the permeability of sandstone and that of granite with a single fracture decrease with increasing effective stress, following the law of exponential decay. the permeability sensitivity of granite to effective stress is more stronger than that of sandstone, but the permeability recovery capability of sandstone is more stronger than that of granite

    試驗結果表明，在圍壓升降過程中，砂巖和單裂隙花崗巖的滲透率均隨有效應西南交通大學博士研究生學位論文第日頁力的增加呈負指數規律減小，但單裂隙試件的滲透率對有效應力的敏感程度遠大於砂巖，而砂巖滲透率的恢復程度則遠大於單裂隙試件。
  5. The results showed that the stress - strain realtionship of pt could be expressed with exponential functions, and there were significant differeces between the normal group and the immobilized group in their theoretical curves of stress - strain relationship and two material constants of pt. also, significant differences were found in tensile strength and tangent modulus between the two groups, but the maximum load of pt in the immobilized group did not decrease significantly

    結果顯示：正常組與制動組間髕韌帶的應力-應變關系理論曲線有明顯不同，其材料常數亦有顯著差異；制動組髕韌帶的極限強度和彈性模量較正常組均有明顯下降，其極限載荷下降不明顯。
