非周期的

And it is further proved that the technique is effective and practical by means of the examples of the extraction of periodic and aperiodic signals.

运用周期和非周期弱信号的检测实例，进一步证明了该方法的有效性和实用性。

Other useful categories include those of periodic or aperiodic signals and random or deterministic signals.

其他有用的分类包括周期信号和非周期信号，随机信号和确定性信号。

This technique is an improved and generalized version of the finite array Green's function method[1], and fit for analyzing all kinds of arrays including finite periodic and aperiodic arrays.

该法不受阵列单元排布形式、单元电流分布情况和单元数量的限制，对有限周期和非周期阵列的分析都有着较高的计算效率和稳定的收敛性。

The result of simulation and experiment showed that in follows:Stochastic resonance in the neuron models was not only for periodic signal but alsofor aperiodic signal.

实验结果表明：神经元模型中的随机共振不仅仅局限于周期信号，对于非周期信号也广泛存在。

Expansion of the wavefunction ; Boundary conditions ; Periodic function ; Nonperiodic function

波函数的展开；边界条件；周期函数；非周期函数

The results also showed that this measure was a good wayto distinguish long period oscillation from a nonperiodic oscillation within the time domain wecould observe.

这些结果也表明这种方法是所观察的时间范围内区分长周期振荡和非周期活动的好方法。

If a is a nonperiodic recurrent point and there is a period point in orb, orb doesn't contain an innumerable scrambled set.

结果 a是符号空间中的非周期回复点，且orb包含一个子转移σ的周期点，则orb不包含一个不可数混乱集。

In this review, we discussed the consequences of inhibiting histone deacetylases in cycling versus non-cycling cells, in light of the dynamics of histone acetylation patterns with a specific emphasis on heterochromatic regions of the genome.

本综述通过讨论HDACIs对周期和非周期细胞中组蛋白去乙酰化酶的抑制结果，来阐明组蛋白乙酰化模式的动力学特征，特别是对基因组异染色质的作用。

System modeling involves with both functional modeling and timing modeling, which relate with computation model (eg, Data-flow-oriented vs. Control-flow-oriented, Uni-processing vs. Multi-processing), time model (eg, Continuous vs. Discreet, Time vs. Untimed, Cycle-based vs. Non-cycle-based, State-based vs. Event-driven, Branching-time vs. Linear-time, Single-rate vs. Multi-rate) and communication model (eg Shared Variable vs. Messaging Passing).

涉及系统建模与功能建模和时间建模，涉及的计算模型（例如，数据流导向与控制流为导向，统一处理与多处理），时间模型（例如，连续主场迎战Discreet公司，时间与Untimed ，周期为基础的与非周期为基础，以国家为基础与事件驱动，分枝时间与线性时间，单率与多速率）和通信模型。

Also it can minimize leakage errors involved in fast fourier transform based measurement and can be pre-emphasized by keeping low crest factor.

与伪随机信号的周期反卷积不同，扫频信号通常都是由非周期反卷积求脉冲响应，这使脉冲响应的长度可以大于信号的长度。

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。
