混沌

From the opposite direction of the parameter variation, the chaotic quasi-attractor suddenly changes to a chaotic quasi-transience due to the sudden appearance of a stable elliptic island chain as the leaking hole inside it. This resembles the conventional crises.

从相反的参数变化方向看，混沌类吸引子在此参数临界值由于它内部突然出现一个稳定的椭圆岛链作为逃逸孔洞而突然转变为混沌类瞬态，这类似于传统的激变行为。

Furthermore, we discussed the chaotic quasi-attractors in a simplified model and found that this chaotic set is the end-results of the image set of the discontinuous border of the system function.

另外，我们讨论了一个简化模型中的混沌类吸引子，发现这个混沌集就是映象函数不连续边界映象集的归宿。

Our numerical results show that the end-results of the image set of the discontinuous border of the mapping function forms a stochastic web.

类耗散性可能使稳定的混沌轨道转变为"混沌类瞬态"，并最终被椭圆岛（可称为"规则类吸引子"）捕获。

If there exists no regular quasi-attractor, the stochastic web, which is formed by the end-results of the image set of the discontinuous border and immersed in a part of the phase space, dominates the system behavior so that iterations are confined inside a part of the phase space in a"chaotic quasi-attractor"(Our research group has discovered the situation where regular and chaotic quasi-attractors coexist in a quasi-dissipative system, but this thesis will not mention it).

当类耗散系统的相空间不存在任何规则类吸引子时，这种由边界象集的归宿构成、浸入局部相空间的随机网将主宰系统，从而出现约束在局部相空间中的"混沌类吸引子"上的运动（本课题组已发现类耗散系统中规则类吸引子与混沌类吸引子共存的情况，本文未作报道）。

It has two characteristics:① the preclude phase\|locking staircase to type V intermittency before entering chaos includes the traditional\|like and multiple\|like devil′s staircase structures;② the chaotic attractor appearing after the staircase always is the end\|results of the image set of the discontinuous borderline.

这类系统中的 V型阵发有两个特点：1系统进入混沌之前展示的 V型阵发前奏锁相阶梯同时包含类似传统魔梯和多重魔梯的结构；2锁相阶梯之后出现的混沌吸引子总是不连续边界象集的归宿

首先应用混沌计算方法：关联维数D2和最大李亚普努夫指数LLE，以及替代数据分析法，分析了男性受试者在平静状态下记录的呼吸系统时间序列的混沌特征。

It is difficult for an eavesdropper to extract information about chaotic systems for every bit of pseudo-random number generator is generated from three different chaotic orbits.

因为伪随机数发生器的每一位是由三个不同的混沌轨道产生的，所以对攻击者来说，提取混沌系统信息是非常难的。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
