Aiming at precision measurement of cylindricity,this paper puts forward a kind of method which can sep- arate the cross- section roundness error,the radius error of different cross sections,the initial coordinates of least square centers of measured cross sections and can reconstruct the pattern of the measured cylinder,i.

本文针对圆柱度误差的精密测量，提出了一种可分离截面圆度误差、截面半径差和截面最小二乘圆心初始位置并重构出被测圆柱形貌的方法，即三点法圆柱度误差分离与重构技术。

在凝缩剖面中，化石和有机物磷酸盐和海绿石质物质相对于几乎不含化石的快速沉积剖面而言，都趋向于被凝缩。

Methods Pathological sections from 68 patients with hilar cholangiocarcinoma were observed by microscope and the distribution of nerve plexuses in normal hepatoduodenal ligament was analyzed based on the observation of 40 histological sections from 5 autopsy cases.

Methods Pathological sections from 68 patients with hilar cholangiocarcinoma were observed by microscope and the distribution of nerve plexuses in normal hepatoduodenal ligament was analyzed based on the observation of 40 histological sections from 5 autopsy cases.

观察68例肝门部胆管癌患者的病理切片，总结归纳肿瘤神经浸润的方式和规律；分析5例尸检标本正常肝十二指肠韧带内的神经丛分布特点。

"Think about a chromosome as being a highway," says Aramayo. In order to function properly, some sections of the highway must have illumination, which means DNA must be expressed, whereas other sections must not have illumination, which means DNA must not be expressed, or that the region must be heterochromatic.

Aramayo说，我们可以将染色体想象成一条高速路，为了正常运行，高速路的一些区段需要照明，也就是说DNA必须被表达；而其它区段则不需要照明，即DNA不需要表达，或这些区段必须被异染色质化。。。。。。。

Methods The solid sections of hepatic segments were obtained by liver incision according to the lines of surface projections of each hepatic fissures The structural landmarks were on lines of section which were observed Results There existed the structural landmarks on the solid sections of median fissure,right interlobar,right anterior lobe,right posterior liver lobe and left hepatic lobe fissures They were showed on the solid images of three dimensional ultrasound.

所谓三维超声立体断层图是指在同一幅超声图像中，同时显示器官或病灶的冠状面和矢状面，或者同时显示冠状面和水平面，或者同时显示矢状面和水平面，构成&蛋糕块&状的立体图像 [1] ，而不是凸凹不平的&立体感觉&。

Hechi-Yishan fault zone is located in the north of Guizhong depression, which general strike is NW-EW and consists of a series of obduction fault. Generally, there are two main faults, the fault-fold belt about 5-20km is made of main faults, subsidiary faults and concomitant folds; The dip of main faults is N or S; It can be divided into four different structural sections along its strike (Hechi section, Yishan section, Liucheng section and Yingshan section). There are some differences among these sections in structure characteristic, such as fault structure, associated structure, fold association style, deformation of rock, and so on.

河池-宜山断裂带展布于桂中坳陷北部，总体走向NW-近EW 向，由一系列逆冲断层组成，主干断裂一般为2条，主干断裂与次级断裂及伴随的褶皱构造构成宽5-20km 不等的断褶带；主断裂倾向N 或S；沿走向可分为河池、宜山、柳城、英山四个构造段；各段断裂结构、伴生构造、褶皱组合样式、岩石变形等构造特征存在一定差异。

Samples were harvested at 6 week and embedded in paraform, and ground sections of the bone tissue were prepared to observe green fluorescence under laser scanning confocal microscope. Propidium iodide staining of the sections was also performed for observation.

将其植入恒河猴背阔肌的肌袋内，以未转染GFP的BMSC用同样的方法接种块状可吸收HA上，作为对照，术后6周取材，4%的中性多聚甲醛固定，塑料包埋，制作骨磨片PI染色在激光共聚焦显微镜下进行观测。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
