混沌

In this paper, nonfeedback chaos control of Chen's system is realized with nonresonant parametric drive.

本文利用非共振参数策动实现对Chen系统的非反馈方式混沌控制。

Moreover,the mechanismunderlying the transition to nonlocal synchronization has been made clear,i.e.,that the oscillators between the nonlocal synchronized sites can transferthe synchronous components,although they stay in nonsynchronous status.

针对这一奇怪的时空动力学行为，我们详细研究了其机制，发现处于非局域混沌相同步中间位置的振子虽然没被锁相，但它们的运动中包含有相同步的元素起到了传递相同步信号的作用。

The concept of stratigraphic pile-up sequences and decomposition model of overlapping process of Logistic chaotic series are applied to extract the weak signal for the sequence of lithologic ratio parameters, which has established the basis for dynamic modeling of three dimensions in the paleogeographic environment of hydrothermal sedimentary basin.

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.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
