  1. After this season of congealed dampness came a spell of dry frost, when strange birds from behind the north pole began to arrive silently on the upland of flintcomb - ash ; gaunt spectral creatures with tragical eyes - eyes which had witnessed scenes of cataclysmal horror in inaccessible polar regions of a magnitude such as no human being had ever conceived, in curdling temperatures that no man could endure ; which had beheld the crash of icebergs and the slide of snow hills by the shooting light of the aurora ; been half blinded by the whirl of colossal storms and terraqueous distortions ; and retained the expression of feature that such scenes had engendered

    潮氣結為霧淞的季節過去了，接著而來的是一段乾燥的霜凍時期，北極後面一些奇怪的鳥兒開始悄悄地飛到燧石山的高地上來這些骨瘦如柴的鬼怪似的鳥兒，長著悲傷的眼睛，在人類無法想象其廣袤寥廓的人跡罕至的極地，在人類無法忍受的凝固血液的氣溫里，這種眼睛曾經目睹過災難性地質變遷的恐怖在黎明女神播灑出來的光明裡，親眼看到過冰山的崩裂，雪山的滑動在巨大的暴風雪和海水陸地的巨變所引起的漩流中，它們的眼睛被弄得瞎了一半在它們的眼睛里，至今還保留著當時看到這種場面的表情特點。

  3. This paper is concerned with, the existence and stability of travelling wave solutions for the viscous balance law which is an extension of viscous conservation law where a reaction term g ( u ) is added. l ) the existence of travelling wave solutions by geometric singular perturbation method, we investigate the existence of travelling waves ( a2 ) connecting a saddle point and a sink point and the existence of viscous shock waves c connecting two adjacent or disadjacent saddle points. by giving a detailed analysis of the fast and slow manifolds and verifying the transversality of the intersection of singular stable and unstable manifolds of the reduced problem along the singular heteroclinic orbit, we obtain the existence of travelling waves ( a2 ) in the case of a convex flow function / and that of viscous shock waves c under the assumption that f " is bounded

    有一個演員手裡拿著一把扇子和一些碎紙片，演出了非常美妙動人的「群蝶花間舞」另一個演員用他那從煙斗里噴出來的一縷芬芳的煙霧，在空中迅速地寫出許多青煙文字，這些字構成一句向觀眾致敬的頌詞又有一個耍拋物戲的演員，他一面把幾支點著的蠟燭輪流地從手裡拋起，一面把每一支從嘴前面經過的蠟燭吹熄，然後再陸續地把它們點著，同時卻一秒鐘也不中止他那神奇的拋擲動作。
  5. Especially, when the isocline of x is monotone decreasing in 0 < x < 1, the svstem has no limit cycle and is globally stable ; next, we construct a saddle bifurcation at the boundary equilibrium and a degenerated bogdanov - takens bifurcation at the interior equilibrium by choosing appropriate parameter values in the following two sections, where our work are based on the theory of central manifolds and normal torms. we prove that is a codimention 3 focus - type equilibrium. system ( 6. 1 ) will have two limit cycles at some appropriate bifurcation parameter values, and have homoclinic or double - homoclinic orbits at some other appropriate bifurcation parameter values ; at last, we study the qualitative properties of the system at infinite in the poincare sphere

    因為系統在（ 0 ， 0 ）點處沒有定義，這給研究其在（ 0 ， 0 ）附近的動力學性質帶來了困難，我們應用文獻[ 17 ]中關于研究非線性方程奇點的系列理論和方法，圓滿解決了這一問題，給出了第一象限內當t +或t -時，在全參數狀態下系統的軌線趨于（ 0 ， 0 ）點的所有可能情況，其相圖也得以描繪；並且，系統不存在極限環的幾個充分條件我們也予以列出，當x的等傾線在0 x 1范圍內遞減時，系統不存在極限環，全局漸近穩定；然後，我們以中心流形定理和正規型方法為主要工具，巧妙選擇參數，分別構造了一個余維2的鞍點分岔和一個余維3退化bogdanov - takens分岔，證明了平衡點是余維3的焦點型平衡點，存在參數， m ，的值使得系統（ 6 . 1 ）有兩個極限環，還存在參數， m ，的另外值使得系統（ 6 . 1 ）有同宿軌或雙同宿軌。
