不规则

Trying to describe how the five planets in the night sky followed seemingly irregular paths, Ptolemy hit upon an idea he called epicycles .

当设法解释夜空中的五颗行星为何好象沿着不规则的轨道运行时，托勒密脑海中闪现出一个观念，他称之为"本轮"。

Its content was only 0.945%±0.492％ of the disc dry weight.The elastin was obviously reduced at deep laminae of annulus fibrosus.④On the elastin fibers of the pathological discs,the fraying,irregular holles,crevice were showed.

突出椎间盘弹性蛋白纤维密度降低，含量明显减少，仅占椎间盘干重的0.945%±0.492％，尤以纤维环深部降低明显，弹性蛋白纤维上出现磨损、裂隙、不规则空洞等。

Owing to the monotonic mapping of fuzzy structured element established the homeomorphic property between fuzzy number space and the family of standard bounded monotone function, so, we can transform the study of any properties in fuzzy number space to the corresponding one in the family of standard bounded monotone function, e.g.

本项目针对矿井下采空区岩石陷落形成的多孔隙介质空间的极度不规则性，建立一种以模糊值函数分析学为基础的、更接近于刻划采空区内气体流动实际状况的模糊微分方程及各种边值问题，进而得出解算复杂采场气体模糊渗流问题的数学方法。

The anatomical study deepens the knowledge of G-type conducting cells: 1 It proves the theory of two depositional process for secondary wall (Bierhorst, 1960): the discontinuous cellulose layer is laid down before the continuous lignified layer; the former layer is prone to be broken down, while the latter is highly decay-resistant; 2 It suggests that the cellulose primary and secondary walls of tracheids are not perforated. Instead of longitudinal pits (Li, 1992), the lignified tracheid secondary wall of Hsüa possesses irregular simple perforations; 3 In Hsüa reflexa and Huia gracilis, the perforation casts may represent the thickness of lignified secondary wall; 4 The wall structure of G-type tracheid is diversified. At the genus level, the secondary wall structure differs in the distribution, internal shape and structure of the perforations; 5 Perforations of some G-type tracheids combine the characters of S-type tracheids in their distribution, density and diameter.

解剖学的研究加深了对G-型输水管胞的认识 1）验证了管胞次生壁分两个阶段形成的理论（Bierhorst，1960），即先后形成不连续的纤维质层和连续的木质化层，前者易被分解，后者抗侵蚀性强；2）证明管胞纤维质的初生壁和次生壁不具穿孔，Hsüa管胞的木质化次生壁具有不规则的简单穿孔，而不是纵列的纹孔（Li，1992）；3）Hsüa reflexa和Huia gracilis的穿孔铸体可代表木质化次生壁的厚度；4）G-型管胞壁层结构具多样性，植物属一级的分异主要表现在次生壁穿孔的分布、孔腔形状和结构的不同；5）某些G-型管胞的穿孔在其分布、密度和孔径方面可兼有S-型管胞的特征。

This in turn, allows the moist and warm mucous membranes to clean, humidify and regulate the temperature of air entering the lungs.

两个鼻孔的边缘是不规则的突出，从而增大了内壁的表面积，也能阻隔尘土和异物，从而留在鼻腔。

Surfaces may be fairly smooth or irregular, hummocky or ridged.

其表面也许是相当平滑或不规则，成波形或背状。

The probabilities are increasing, in an irregular and immeasurable manner, as knowledge and materials become available to those who wish us ill. Fear may recede with time, but the danger won't the war against terrorism can never be won. The best the nation can achieve is a long succession of stalemates. There can be no checkmate against hydra-headed foes.

这种可能性，正以一种不规则且难以衡量的速度逐渐增加当中，随时仇视我们的敌人渐渐掌握伤害我们的信息及资源，恐惧的心理或许会随着时间慢慢淡化，但危险却依然存在，对抗恐怖活动的战争永远不会结束，我们能够得到最好的结果是让问题控制在一定程度之下，对于铲除仇视我们的狂热份子绝无根治之道。

The seepage of irregular fracture is a very important problem in rock hydraulics.

不规则裂隙的渗流问题是岩体水力学中一个比较复杂的问题。

The generation of regular mesh is easy and simple, and as for irregular computational mesh hydrologist usually generated it manually.

规则网格的自动生成很简单，不规则网格的生成，水文中一般采用手工方法。

The results showed that Pleurotus tuber-regium was solitary or tufted, it's primodium was milk-white and weight was generally 48~78g, the biggest was 220g. The structure of Pleurotus tuber-regium included three stories: the outmost story was epidermis, the middle was medulla, and the undermost was hymenium.

结果表明，虎奶菇子实体为单生或丛生，原基乳白色，一般朵质量为48~78g，大的可达220g；其结构分为3层，上层表皮层，中间层为髓部，下表层为子实层，表面起伏不平，有不规则疣状突起。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
