  1. Equation ( 4 ) is said to belong to limit circle type if all solutions of equation ( 4 ) belong to l ~ ( 2 ) ( simply denoted by l. c. ) equation ( 4 ) is said to belong to lagrange stable if all solutions of equation ( 4 ) belong to ( simply denoted by l. s. ). in chapter 4, we study criteria for the linear nonhomogeneous differential equation belonging to the limit circle type

    方程( 』 )稱為極限圓型的,若方程( 』 )的所有解都屬于護[ a , co ) (簡記為l . c . ) ;方程( 』 )稱為拉格拉日穩定,若方程( 』 )的所有解均屬于lco [ a , co ) (簡記為l . s . ) .由於方程( 』 )解的平方可積性及有界性的研究在微分運算元理論、按微分方程的特徵函數展開理論以及無界區間上受控系統的最佳控制理論等方面具有重要應用
  2. The spatial directional resolution ( sdr ) of the 2 - d regular arrays ( square array, circle array, l array ) was investigated in this paper by means of theoretical analyses and computer simulations

    摘要利用理論分析和計算機模擬相結合的方法、對三種常用的二維均勻天線陣列(方陣、圓陣、 l陣)的空間方向特性進行了深入的理論和模擬實驗研究。
  3. On the direction of sequence stratigraphy theory, writer sets down unit framework in this gas field on the basis of analysis of logging data of 42 wells, seism synthesize and api of 17 wells and 155. 5m core data of 8 wells. four key interface, fifteen three stage sequence interface are been set off in the research strata. the substrata are been divided and contrasted in controlling grade with low circle mode l

    在層序地層學理論的指導下,用42口井的測井曲線、 17口井的地震合成記錄以及波阻抗資料和8口井共155 . 5米的巖芯資料,建立了全區地層格架,在研究層段內,共劃分了四個關鍵界面、十五個三級層序界面,在地層格架內分級控制,採用小旋迴對比法對全區各層段小層進行了劃分和對比。
