The main components of the lathe are the headstock and tailstock at the oppoaite ends of a bed,and a tool-post between them which holds the cutting tool.the tool-post stands on a cross-side which enblesit to move sidewards across the saddle or carriage as well as along it,depending on the kind of job it is doing.the ordinary centre lathe can accommodat only one tool at at time on tool-post,but a turret lathe is capable of holding five or more tools on the revolving tueeet.

刀架位于一个纵面板上，小拖板使刀架能够根据加工操作的不同作纵向移动；同时又随大拖板作横向移动。普通顶尖车床只能在刀架上夹持一件刃具，但六角车床可以在其旋转的六角刀架上夹持五件或更多的刃具。车床的床身必须很牢固结实以避免在受力的时候弯曲和变形。请提问的同学最好参观一下工厂的金属切削/机加工车间。那里有车床，还有其他种类的金属切削机床。

This influence is particularly outstanding at vanguard fashion design The contemporary art of vanguard fashion design exits in works' original design, it reflected t-he idea and current of thought of the vanguard contemporary art. Since 1990s, having been gone through the strong impact of modernism, post-modernism and post-post-modernism, which is neonatal in realm of philosophy, western art have gradually tend to be unreasonable, unaesthetic and anti-centric.

前卫时装设计中的当代艺术性存在于作品的原创设计中，它反映了当代文化艺术前沿的观念与思潮。20世纪90年代以来，西方艺术经历了现代主义、后现代主义以及新生的后后现代主义的强烈冲击，逐渐具有了反理性、反审美、反中心的创作倾向。

In the second group of which pancreas allogenic graft was made combining with duodenum: schistic necrosis of pancreatic gland alveolus at 3 d post operation, necrosis of pancreatic folia and pancreatic islet at 5 d post operation, widespread necrosis and disappear of structure at 7 d post operation were observed.

胰、十二指肠移植组：术后3 d胰腺腺泡细胞片状坏死；术后5 d胰腺小叶和部分胰岛细胞坏死；术后7 d腺泡细胞大片坏死，胰岛结构消失。

Results While the ES lumen and perisaccular region were infiltrated with mononeuclear-phagocyte at the 3rd day post-vaccination, plasmocyte and lymphatic cells become the predominant infiltrating cells in the ES at the 7th day. The KLH in the ES lumen were phagocytized at the 3-7th day post-vaccination. S-phase cells and IgG positive cells in ES increased markedly in the 3rd day and 7-14 days post-vaccination respectively with similar localization.

结果 内耳受抗原刺激后3 d内淋巴囊囊腔和囊周区域出现单核吞噬细胞浸润，7 d内淋巴囊的浆细胞和淋巴细胞大量增加；3～7 d内淋巴囊囊腔KLH被吞噬，同时S期细胞和IgG阳性细胞逐渐增多，二者的出现部位相似。

Not only that, but the painting is also the history of the early post-yi and the image is recorded, it is the study of the history of China Post, has great awareness of the significance and value of academic research, so in 1982, to commemorate the establishment of All-China Philatelic Federation and the first convening of Congress, Ministry of Posts and Telecommunications to the "station to make map" under the pretext of issuing commemorative stamp sheetlet to witness the China Post's long history and glorious history.

不仅如此，这幅画也是中国早期邮驿历史真是而又形象的记录，它对于中国邮政历史的研究，具有重大的认识意义和学术研究价值，因此在1982年，为纪念中华全国集邮联合会成立暨第一次代表大会的召开，邮电部将其以《驿使图》为名，发行小型张纪念邮票，以见证中国邮政的悠久的历史与辉煌历程。

The results of this study indicate that: 1 the post–surcharge secant secondary compression index decrease with the increase in surcharge ratio; 2 the amended post-surcharge secant secondary compression index also decrease with the increase in surcharge ratio; 3 time at which secondary compression reappears increases with the increase in surcharge ratio; 4 the post-surcharge secondary compression strain rate under the same final load with surcharging and without surcharging have a linear logarithm to logarithm relationship.

根据研究的结果显示：1超载比愈大，后超载割线二次压缩指数所受到的折减愈大，表示对软弱粘土的二次压缩沉陷量改良效果愈好；2修正之后超载割线二次压缩指数亦随超载比的增加而折减；3二次压缩再现时间与超载比的关系显示，增加超载比会延迟二次压缩再现的时间并可将分析结果以一均值曲线表示； 4对后超载应变速率分析发现在相同最终载重，未受超载作用与受超载作用的二次压缩应变速率呈现一双对数的线性关系。

In order to unsterdand the properties of rebound and recompression, this study carried out oedometer tests for six soft clays with three surcharge ratios to simulate surcharging. Properties analyzed in this thesis include: 1 post–surcharge secant secondary compression index; 2 amended post- surcharge secant secondary compression index in which the time starts from load application; 3 time at which secondary compression reappears; 4 post-surcharge secondary compression strain rate.

为探讨软弱粘土於超载移除后的回胀与再压缩性质，本研究利用传统单向度压密试验仪对六种土样分别进行三种超载比的超载单向度压密试验，并分析所得结果，分析方法包括：1评估后超载割线二次压缩指数；2评估修正后超载割线二次压缩指数，将后超载的时间原点改为由加载起始时起算；3评估二次压缩再现时间与超载比的关系；4评估后超载二次压缩应变速率之特性。

The first post in a thread defines the name of the thread. Therefore, the topic of the first post in a thread should be descriptive enough to give participants in a forum enough of an idea what the question is or what your opinion is that they can decide whether to participate without having to access the post's body.

一个主题的第一篇文章决定了这个主题的标题，因此主题的第一篇文章应该主题鲜明，以便吸引有兴趣的人参与讨论。

记者浏览网友们的回复看到，除了称赞发帖者勇气可嘉之外，更有网友提供了寻人方法，&去当地的网吧发帖，去当地人气旺的论坛发帖等等都可以，最笨的一个办法就是有时间就在下午4点半左右去坐同一趟大巴，守株待兔，应该会有机会找到的。&
