Lateral crus presented diamond-shaped or long strip,(16.21 ± 2.71) mm in length,(8.45 ± 1.72) mm in width,(1.09 ± 0.18) mm in thickness. Cephalic rim intersected lower edge of lateral nasal cartilage, and slightly covered the lower edge of the lateral nasal cartilage, so that the two were overlapped, but also only the intersection without overlapping. Lateral crus constituted the base of nasal wings. Narrow medial crus formed nasal tip and the frame of front nasal columella, showing posteroinferior curve or S shape,(13.06 ± 2.16) mm in length,(3.79 ± 0.58) mm in width,(1.02 ± 0.18) mm in thickness. The left and right medial crus in the middle were connected by connective tissue, and in the same way connected to the anterior margin of the lateral nasal cartilage.

第五章中认为不仅不同类型的重叠式状态形容词之间存在着程度量等级差别，而且同一重叠形式之内也存在着程度量等级的差别。

Thist paper chooses 90 groups of "Tong_su_yi_xu synonymic words" from "Modern Chinese dictionary ", and divides them into three kinds according to the interpretation method in the dictionary, regards web page of Sohu website as the platform, us.es the search engine to carry on the search of the word , count the frequency that every group"s word appears , and rejects artificially the mistakes appearing in all web pages that can be opened, language fact presented in observation post then carefully (namely the example sentence with this word appearing in the webpage), and find that the 90 groups of "Tong_su__yi_xu synonymic words" except that the meaning of a word is the same, have quite a few of at frequency of utilization and concrete usage for difference: Because people"s use habit and word use the difference on to cause the appearance frequency of the word analogous to or with a wide gap, because of word-building ability, the word collocates, the word overlaps or the language usually overlaps, linguistic context of area and times , the meaning of a word that the word appears are abstract and concrete, semanteme is laid particular emphasis on, the morphological feature-change, etc.

本文从《现代汉语词典》中选取90组同素异序同义词，按词典中的释义方法将其分成三类，以搜狐网站的网页为平台，运用搜索引擎进行词语的搜索，统计下每组词语出现的频率，并将所有能打开的网页中出现的错误进行人工干预，然后仔细观察所出现的语言事实(即网页中出现的含有该词语的例句)，发现这90组同素异序同义词除了词义相同之外，有相当一部分在使用频率和具体的用法上还存在着差别：由于人们的使用习惯和词语使用上的差异造成词语的出现频率相当或者相差悬殊，又因为构词能力、词语搭配、词语重叠或语素重叠、词语出现的区域和年代语境、词义抽象与具体、语义侧重、词性变化等方面的差异造成词语使用上的区别。

The temporal and spatial niche breadth value of Propylaea japonica was maximum, and the temporal niche overlap value of Theridion octomaculatum between dominant predatory enemies and Aphis gossypii was maximum and the spatial niche overlap of Pardosa T-insignita was maximum.

对淮北棉田节肢动物优势种群组成和时空生态位进行分析，结果表明：棉蚜、烟粉虱、棉叶螨、棉盲蝽、四点亮腹蛛、龟纹瓢虫、T-纹豹蛛、草间小黑蛛、八斑球腹蛛、华姬猎蝽、小花蝽和青翅隐翅虫为优势种群；时间和空间生态位宽度值都是以龟纹瓢虫最大，捕食性天敌优势种群与棉蚜时间生态位重叠值以八斑球腹蛛最大，空间生态位重叠值以T-纹豹蛛最大。

In chapter 2, we focus on derivation of the tortuosity models for flow of Newtonian incompressible fluid in two- and three-dimensional porous media with spherical, cubic and plate-like particles by applying the geometrical method. We first present the ideal geometrical models of porous media to show the ideal and representative streamlines based on the assumption that some particles in porous media are unrestrictedly overlapped and hence of different configurations, then the average tortuosity is derived by geometrically and weightedly averaging these representative flow paths.

第二部分采用几何分析法研究了二维和三维情况下的球形颗粒、立方体颗粒和板状颗粒多孔介质中流体流线的迂曲度，首先给出多孔介质的理想几何模型，通过分别考虑固体颗粒重叠时、不重叠时以及粒子的不同排列等情形时的流体流线，然后对这些理想代表性流线的迂曲度取几何平均和加权平均，最后推导出流体流过多孔介质的迂曲度解析表达式。

By comparing with known compound A2'P 5'A,it was shown that two ribose rings of a and b adopt predominantly S conformation at 18℃, but with elevation of temperature, the N conformation of some ribose ring increaed: the torsional angles e' and β of the phosphate backbone were estimated to have a change of +2° and ±12°respectively; two ribose rings of both A2'P(CH3)5'A and were partially overlapped and the degree of overlapping of was smaller than that of the : with increasing of temperature, the adenine moiety of A2'P(CH3)5'A showed a stronger tendency to unstack than A2'P(CH3)5'A .

它们与A2′P5′A相比发现：(1)在18℃时两个核糖环是S型构象占主要成分，但随温度升高有的核糖环趋向于转化成N型构象；(2)磷酸骨架的扭角ε′和β分别改变±2°及±12°；(3)A2′P(CH_3)5′A和的两个核糖环均属部分重叠，并且前者的重叠程度小于后者；(4)随着温度升高，A2′P(CH_3)5′A比A2′P(CH_3)5′A有着更强的去堆积效应。

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.
