Fractal is a subdiscipline of nonlinear area, researches on fractal characteristics of the deoxyribonucleic acid sequence may reveal some secret hidden in the DNA sequence during the process of biological evolution. Chaos Game Representation was proposed as a scale-independent representation for genomic sequences by Jeffrey in 1990. This technique, based on iteration function system, represents the word distribution statistics in DNA sequence as the fractal graphic. Therefore, we can get the distribution of sequence through analysis of fractal theory.

分形是非线性领域的一门分支学科，关于脱氧核糖核酸序列分形特征的研究，可以揭示生物在进化过程中隐藏在DNA序列中的某些秘密。1990年Jeffrey提出了基因组序列的与尺度无关的混沌游戏表示法，这是基于迭代函数系统的一种方法，它将DNA序列中一定长度字的分布规律表现为图形的分形特征，进而通过分形分析就可获取序列的分布规律，从而也成为DNA序列分析的一种统计方法。

The inverse series is non-linear in the scattered field, which includes the source wavelet and a chosen reference medium's properties.;An imaging subseries of the inverse series for a 1-D constant density variable velocity acoustic medium is isolated and analyzed.

逆系列是非线性的散射场，其中包括小波的来源和选择范围中的属性。；的成像亚逆系列一维密度不断变速声中被孤立和分析。

Initial symptoms are nonspecific; fever is usually present and other symptoms may include chills, headache, myalgia, conjunctival suffusion, nausea, or diarrhea. The CDC notes that leptospirosis should be included in the differential diagnosis of any worker who presents with febrile illness within 1 month of participating in a flood clean-up.

感染钩端螺旋体的起始症状是非专一性的，几乎所有病患都会发烧，其他症状包括畏寒、头痛、肌肉痛、结膜泛红、恶心或是腹泻；CDC表示，钩端螺旋体应该列入任何曾经於洪水地区参与清理的人们发烧的鉴别诊断之一。

It is not an imperative carved in stone; it is a human idea, and human beings are frail and suggestible, and sometimes get the wrong end of the stick.

它不是由上帝颁布刻在石上的伦理十诫中的一诫，它是人类的想法，而人是容易受到引诱耳根发软的，有时甚至还会完全是非颠倒。

The length of the sunward merging line between the two peaks of reconnection potential shows a non-monotonic variation in response toθ_,peaked atθ_=90°,so it is also not justified to take electric fields along the merging line to characterize the the total reconnection rate and the coupling strength between the solar wind and the magnetosphere.

3向阳侧磁合并线电势的最大值和最小值之间的合并线长度与θ_IMF的关系是非单调的，在θ_=90°时最长，因此用合并线上的电场来取代重联电压来表征总的重联率和太阳风一磁层耦合程度也不合理。

The reached supercoolings are larger than the critical supercooling of 0.2 in the classical nucleation theory.

本文则揭示了某些金属的比热随温度的变化是非单调的，因此外推法是不适用的。
