非周期的

Chaos Theory is the qualitative study of unstable aperiodic behaviour in deterministic non-linear dynamical systems.

在确定性的非线性动态系统中，混沌理论是针对不稳定的非周期行为的量性研究。

New sequences with good aperiodic ACF properties are presented. The results obtained by an evolutionary algorithm are better than other known results in most cases.

阴道鞭毛虫为WHO宣布为最广泛的非病毒性性接触传染疾病，已证实会造成HIV感染机率增加、与子宫颈癌、不孕症有关联性，且其细胞周期的G2期较G1期长，但对阴道鞭毛虫的仍不清楚。

Spontaneous activities of SNc neurons in brain slice of young rats were recorded extracellularly, which were divided into periodic and non-periodic firing patterns.

通过研究黑质致密部(substantia nigra compacta，SNc)神经元的放电型式与其对谷氨酸、多巴胺及缺氧敏感性的关系，探讨&非周期敏感&现象在神经系统的普遍性。

Firstly,Shanghai and Shenzhen stock return time series do not follow normal distribution,it presents leptokurtic and fat-tails;secondly,it is characteristic of long memory,non-linear,persistence and Non-periodic Cycle,which are obviously fractal market Features;finally,we discuss the chaotic dynamic characteristics of tow market,witch can prove the fact of fractal market from the side.

首先，沪深股市的收益率时间序列波动不服从正态分布，而是存在尖峰、胖尾和右偏的特征；其次，序列具有状态持续性，统计自相似性，非周期循环长度，等分形特征；最后，对两市的混沌动力学特征进行了初步探讨，从侧面印证两市为分形市场。

Simulation results show that the strategy is effective for prolonging the network lifetime.

仿真实验表明，非均匀的节点部署策略能有效延长网络的生命周期。

An integrable model with non-period boundary condition is constructed by use of factorized L operator.

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。
