衰落

Many modern genera of conifers arose in the Tertiary, but other gymnosperms declined.

许多现代的松属植物是在第三纪产生的，然而其他的裸子植物开始衰落。

Now the humanities have become the Ottoman Empire of the academy, a sprawling, incoherent, and steadily declining congeries of disparate communities, each formed around one or another credal principle of ideology and identity, and each with its own complement of local sultans, khedives, and potentates.

现在人文科学已经变成了学术界的奥斯曼帝国，一个持续衰落的、不断蔓延扩张的，不连贯的团体的堆积，每个派别都形成一个或者又一个意识形态或者身份的信条，每个派别都有自己的本土苏丹、赫迪夫和君主。

Add fading effects to tables, divs and more.

添加衰落的影响，表， divs和更多。

You must learn to use your downfalls and setbacks as opportunities to grow and reach new heights.

你必须学会利用衰落和挫折作为发展和达到新高度的机会。

The worst frost damage occurs in areas that are usually frost-free, where exposed mature tropical trees, such as mango, or indigenous plants , such as tree ferns and eucalypts, can be set back or even killed.

最严重的霜冻破坏经常发生在像暴露在外面的成熟起的热带雨林那些霜冻经常发生的地区。像蕨类植物的树木，和桉树，会衰落或死亡。

The worst frost damage occurs in areas that are usually frost-free, where exposed mature tropical trees, such as mango, or indigenous plants, such as tree ferns and eucalypts, can be set back or even killed.

最严重的霜冻灾害发生在通常没有霜冻发生的地方，在这些地方裸露在外的，芒果等成熟的热带树木，或是蕨类植物和桉树等土生土长的植物，会衰落甚至死亡。

In order to improve the simulation performance, a method based on sum of sinusoids to implement Rayleigh faders with special doppler spectrum is presented.

为克服这些缺点，提出了一种基于正弦波叠加的方法来实现短波信道中特定多普勒谱的Rayleigh衰落因子。

The results are valid for arbitrary diversity order and the amount of fading, and are obtained for Rayleigh-lognormal, Ricean-lognormal and Nakagami-lognormal composite fadings.

该方法对于任意分集支路数目下的Rayleigh-lognormal，Ricean-lognormal和Nakagami-lognormal三种复合衰落环境均是有效的。

In wireless broadband digital communication, Inter-Symbol Interference caused by time disperse of radio channel is one of main factors that limit bandwidth of communicated information and system performance of communication. In receiver, Orthogonal Frequency Division Multiplexing system can easily cancel ISI and equalize frequency-selective fadings that are both caused by time disperse of radio channel.

在这一系统中，无线信道时延扩展引起的符号间干扰是限制传输性能和信息速率的主要因素之一；而在消除符号间干扰和均衡由无线信道时延扩展引起的频率选择性衰落方面，正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)技术具有明显优势。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
