To this point he has been discreet in dreading to provoke me ; you must represent the peril of quitting that policy, and remind him of my passionate temper, verging, when kindled, on frenzy
關于這一點，他一直很謹慎，唯恐把我惹急了。你一定要說明白我若放棄這個策略的危險性，而且提醒他我的暴躁脾氣，只要一鬧起來，就會發狂的。A rectangular diagram of a logic function of variables drawn with overlapping sub - rectangles such that each intersection of overlapping rectangles represents a unique combination of the logic variables and such that an intersection is shown for all combinations
一種多變量邏輯函數（求值用）的方格圖，橫行表示一組變量（與取值） ，縱向表示另一組變量（與取值） ，重迭（相交）的方格表示若干邏輯變量的一種唯一的組合（與取值） ，而且表示了所有可能的邏輯變量的組合（與取值） 。In the third chapter, we will study the existence and uniqueness of the classical global solution and generalized global solution to the periodic boundary value problem and the cauchy problem for this kind of equation. in the second chapter, we study the following nonlinear wave equation of higher order : with the initial boundary value conditions or with where a1, a2, a3 > 0 are constants, ( s ), f ( s0, s1, s2 s3, s4 ) are given nonlin - ear functions, u0 ( x ) and, u1 ( x ) are given initial functions. for this purpose, by green ' s function of a boundary value problem for a fourth order ordinary differential equation we first reduce the problem ( 1 ) - ( 3 ) to an equivalent intergral equation, then making use of the contraction mapping principle we prove the existence and uniqueness of the local classical solution for the intergral equation
本文分三章，第一章為引言；第二章研究一類非線性高階波動方程的初邊值問題的整體古典解的存在性和唯一性，以及古典解的爆破；第三章研究此方程的周期邊界問題和cauchy問題的整體廣義解和整體古典解的存在性和唯一性，具體情況如下：在第二章中，我們研究一類非線性高階波動方程的如下初邊值問題：或或其中a _ 1 ， a _ 2 ， a _ 3 0為常數， （ s ） ， （ s _ 0 ， s _ 1 ， s _ 2 ， s _ 3 ， s _ 4 ， ）為已知的非線性函數， u _ 0 （ x ） ， u _ 1 ， （ x ）為已知的初始函數，為此，我們先用四階常微分方程邊值問題的green函數把上述問題轉化為等價的積分方程，然後利用壓縮映射原理證明此積分方程局部古典解的存在性和唯一性，又用解的延拓法證明上述問題整體古典解的存在性和唯一性，主要結果有：定理1設u _ 0 （ x ） ， u _ 1 （ x ） c ~ 4 [ 0 ， 1 ]且滿足邊界條件（ 2 ） ，若以下條件滿足：其中a ， b月0為常數， wWhen, there exists at least one limit cycle to the system ( * ) in the first quadrant ; theorem 2. when, there exsits at most one limit cycle to the system ( * ) in the first quadrant ; theorem 3. when, there exactly exists one limit cycle to the system ( * ) in the first quadrant
我們得到下列結論：定理1 、當時，系統（ * ）在第一象限內至少存在一個極限環；定理2 、當時，系統（ * ）在第一象限內至多存在一個極限環，若存在必為穩定的；定理3 、當時，系統（ * ）在第一象限內存在唯一的極限環，且為穩定的。And so, if mammas told sonya looked on the countess and addressed her as a mother, shell say that im spoiling nikolays career, that i have no heart, that im ungrateful, though really in gods name she made the sign of the cross i love her so, and all of you, only vera why is it
