中线

In this method,the Archimedes spiral was adopted as channel midline which could be generated by programmer in the process of modeling,and the original wooden patterns and the area change rule of channel could be modified,so that 3-D design of double-channel impellers could be implemented.

在该设计方法中，采用阿基米德螺旋线为流道中线，在造型过程中编入程序生成流道中线，并对原木模图和流道面积变化规律进行修正，实现对双流道式污水泵叶轮的三维设计。

A formula was deuced, which shows the relation between the outlet angle of center line of channel and wrap angle, variant coefficient, if variant Archimedes spiral is assumed the curve of center line of plate plane. It is the basis for controlling outlet angle of channel.

推导了采用变异的阿基米德螺线作为平面流道中线时，中线出口角与包角和变异系数之间的关系式，为设计中控制流道出口角提供了依据。

Embryo 7 weeks, Maxillary Tunisia Tunisia at the top connected to the formation of nasal and nasal Department, in the middle and small ball connected to the formation of Tunisia at the bottom of the nose and upper lip, two small balls connected to the formation of Tunisia in the midline nasal columella, lip people and ex-jaw.

It was shown that the TRH test is closely correlated with the injury types,the shift degree of brain,midline and the volume of EDH respectively on CT.The reduced reactions were most seen in the groups of SDH and midline shift ab...

结果发现：CT所表现的损伤类型、脑中线移位程度及EDH血肿量与TRH兴奋试验的改变有密切关系，反应不良出现率以SDH组及脑中线移位≥10mm组最高，EDH血肿量越大，TRH兴奋试验改变也越明显。

Yesterday the diversion project starts middle Taocha Headwork mobilization meeting in the city of Nanyang Xichuan 9 Taochvillage headworks at the construction site marking the Water Diversion Middle Route Project has entered a new stage.

昨日，南水北调中线陶岔渠首枢纽工程开工动员大会在南阳淅川县九重镇陶岔村渠首施工现场举行，标志着南水北调中线工程进入一个全新荒阶段。

Month postoperation, the tissue-engineered skin grafted to the left back of swines remained living with obvious keratinization, but it had no pigmentation. The acellular dermal matrix grafted to the right back of swines converted into guanulation tissue with local crusta, and margins of the skin defects contracted.

术后1个月，实验猪背部正中线左侧移植的组织王程皮肤成活良好，表皮角化明显，色素缺失；正中线右侧移植的猪脱细胞真皮形成肉芽组织，局部结痂，创缘收缩明显。

To the side of the center line move over 2 and draw a line parallel to the center line.

到中线一侧移动了2，划一条平行于中线。

Based on the methods of Fuzzy Synthetic Evaluation in Fuzzy mathematics methods and the theories of Pedology and Ecology,the authors defined some membership functions to deal with the information date gathered from the railway of Bao |zhong,found the nature of ecological changes in the railway of Bao zhong in varied time and places and achieved a good result.

利用模糊数学中综合评判方法及土壤学、生态学理论构造了评价模型及一系列因素的隶属函数，用于处理收集到的宝中线有关生态信息数据，获得了宝中线生态时空变化规律。

The next point to be staked is a common issue in the GPS RTK staking. It is proposed in this paper that the coordinate of a certain point be used to determine its direction and perpendicular distance from the road center.

在GPS RTK道路中线测设时，常遇到下一个点在何处的问题，做法是随测一个点的坐标，反算出该点趋向道路中线的方向与垂距，在行进之中，实现导向与导距。

METHODS: Using thoracic computed tomography scans of 100 adults,we measured the distance from skin surface to pleura and tointrathoracic structures at the level of the sternal angle atthe midhemithoracic line, and at the level of the xiphoidprocess at the anterior axillary and midaxillary lines, as wellas the distance from the sternal midline to internal mammaryvessels.

通过对100位成年人进行胸部 CT 扫描，我们测量出胸半中线上胸骨角平面及腋前线和腋中线上剑突平面上皮肤表面至胸膜和胸腔内结构的距离及胸骨中线至内乳血管的距离。
