Using sentences in Nature to classify sentences, it is discovered that the dominant sentences in number are the simple sentence in structure and next to it the one-clause sentence. The DSIN are featured by three phrases: verbal noun phrases and verbally derived noun phrases, the impersonal sentence, and V-ed, V-ing phrases.

采用语料分析的方法，研究Nature论文的句子类型，结果发现：论文的主流句是简单句占51%，带一个从句的句子占36%；Nature论文语言存在三大语言特征：频繁出现动作性名词和动词派生的名词话语形态、非自然关系句和由V-ed或V-ing构成的话语形态。

The asymmetric coefficients of debris flows are quite different in different area: large asymmetric coefficients of debris flow with low resistance; small asymmetric coefficients of debris flow with high resistance. The asymmetric coefficients of debris flow could be used to classify resistance characteristics of debris flow accurately and the resistance law of viscous debris flows was got by asymmetric coefficients.

泥石流的不均匀系数在不同的泥石流地区有很大的不同：不均匀系数小的地区阻力大，而不均匀系数大的地区阻力小，因此可以用不均匀系数划分泥石流沟的阻力特征，从而得到能兼顾所有不同地区的泥石流阻力规律。

自然界中木聚糖是多种糖类的复合体，这就使得木聚糖酶呈现多态性和多域性，由此需将繁多的木聚糖酶进行归类。

In this paper,we discuss the Walsh spectral characteristics of partially-bent functions over ring Znq(q=p1*p2,p1、p2 are primes),propose two new concepts―nonzero factor variant-permanently linear structure and zero divisor variant―permanently linear structure,classify the variant-permanently linear structure of partially-bent functions and show their correlation,obtain several new equivalent conditions of partially-bent functions on ring Znq,finally,point out the correlations among balance, linear structure and points taking nonzero spectrum.

本文在环Znq上讨论了部分bent函数的谱特征(q=p1*p2，p1，p2是素数)，得到了Znq上部分bent函数的几个新的刻划，揭示了部分bent函数的平衡性、线性结构点及非零谱值点之间的相互关系，并对部分bent函数的恒变线性结构点进行了分类，指出了它们之间的相互关系，提出了零因子恒变线性结构点和非零因子恒变线性结构两个新概念。
