周期

For Lienard equation X +fx'+ ex = e, we obtain that if and for any periodic function or almost periodic function e it has a periodic solution or an almost periodic solution.

而对于Lienard方程x＋fx'＋cx＝e，我们得到：当c＞0且时，对于任意周期、或概周期函数e，它有周期或概周期解。

Solvability of (0,δm),(o,m1,Am2,/m3)-interpolation problems on π-antiperiodic function and some of 2-oeriodic situation were discussed, and some fundamental problems on ;π-antiperiodic function were considered in this aspect.

The periodic correlation function and aperiodic correlation function are discussed in this thesis.

本文讨论了序列的周期相关函数和非周期相关函数，归纳总结了部分周期相关函数的概念及性质，与此相对应给出了部分非周期相关函数的概念。

Further more, we put forward a mixed tasks scheduling algorithm that canprocess periodic and aperiodic tasks.

第三，在以上算法的基础上，进一步提出了既可调度周期任务也可调度非周期任务的混合任务调度算法，它将所有非周期任务转化为周期任务进行调度，并有效地利用处理机无故障时的空闲资源。

For some special cases, the paper gives some important identical theorems, and then establishes a valuable relation between the uniformly almost periodic functions and the trigonometric polynomials.Secondly, on the basis of the identical theorem, the paper investigates the Fourier series of the uniformly B2 almost periodic functions, and further proves that the series is unique.Thirdly, the paper discusses the Parseval equation of the uniformly B2 almost periodic functions, which establishes the relation between these functions and the coefficients of their Fourier series; and next investigates an important approximation theorem-Riesc-Fischer theorem, about the uniformly B2 almost periodic functions and the trigonometric polynomials.

On the applications of the uniformly Besicovitch almost periodic functions to differential equations, the main works are as follows:First, the paper proves that the space of the uniformly B2 almost periodic functions, with a special norm, is a Banach space, and then the Fixed Point Methods could be used in this function space.Second, since the space of the uniformly B2 almost periodic functions is per-fect, the paper investigates the existence and uniqueness of uniformly B2 almost periodic solution of a wave equation involving reflection of the argument by the principle of contraction mapping.

关于一致Besicovitch概周期函数在微分方程中的应用，本文主要做了以下工作：第一，证明了一致B~2概周期函数空间在其特定范数下构成Banach空间，从而可以在此函数空间上应用不动点定理；第二，由一致B~2概周期函数空间的完备性，应用压缩映像原理，讨论了一类满足一定初始条件的带反射变量的波方程一致B~2概周期解的存在唯一性。

In addition to Kondratieff's economic waves, Modis adds similar 56-year cycles in scientific advances described by himself, and 56-year cycles in infrastructure replacement studied by Arnulf Grubler.

而且，除了Kondratieff发现的这个经济周期，Modis还补充了两个类似的56年周期，一个是他自己提出的关于科学的发展的周期，另一个则是Arnulf Grubler研究出来的基础建设的更换周期。

The plateau-ravine model describes a cycle, but it also describes a metacycle-a cycle of cycles, a spiral, like the chambered nautilus.

高原-峡谷模型描述了一个轮回周期，也描述了一个元周期--也就是周期的周期，这是个螺旋，就好像鹦鹉螺上一圈圈的纹路。

The deterministic neuronal firing model could simulate only the period adding bifurcation scenario in which period n bursting was changed into period n+1 bursting directly. The period adding bifurcation scenario and the new firing pattern similar to the experiment could be simulated in the stochastic Chay model.

确定性神经放电理论模型只能模拟周期n节律直接到周期n+1节律的加周期分岔序列；而随机Chay模型可以模拟实验中的加周期分岔过程和新节律。

These cycles, used in sometimes complicated combinations, are the daily cycle, with hymns for vespers, compline, the midnight prayer, matins, and the four canonical hours; the paschal cycle, which includes the period of Lent before Easter and the 50 days separating Easter and Pentecost and which is continued throughout the Sundays of the year; and the yearly, or sanctoral, cycle, which provides hymns for immovable feasts and the daily celebration of saints.

这些周期，用于在复杂的，有时组合，是每日周期，与赞美诗为晚祷， compline ，午夜的祈祷，晨祷，和4小时的典型；逾越周期，其中包括时期贷出复活节前和50天的分离复活节和圣灵降临节，这是继续在整个星期日的一年；和每年，或sanctoral ，周期，其中规定圣歌为不动产节日和日常庆祝圣人。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
