冲面

Wedge mechanism was adopted in piercing die to achieve side piercing, and the positioning of taper pipe depended upon the conical surface of blanking die itself.

在冲孔模中选用了带有楔角的斜楔机构来实现侧冲，并利用冲裁凹模自身的锥形面实现了锥形管的定位。

As you should know, we have an extremely large lifting surface.

你应该知道的，我们有一个超级大的冲面

Combined a large number of on -site investigate and survey data of loess area in the north of Shaanxi Province, the paper analyzed the influence factors and interrelationship of slope erosion, then put forward the main influence factors , the peculiarity of outwash destructions the main style and protective measures about slope erosion of highway in loess area. The first: the emphasis about protective measures of cut-slope are the selection of rate of grade, the place of plain stage of slope, the slope protection; the second: the emphases about drainage of cut-slope is the rational installation and mating of drainage establishment; And following this principle: the effective holding up , the rapid obviating, the smooth articulation, the seepage prevention and prevent erosion.

根据陕北黄土地区公路的大量现场调查和实测资料，分析了公路边坡冲蚀的影响因素及其相互关系，提出了黄土地区公路边坡冲蚀的主要影响因素、冲蚀破坏特点、主要类型与防护对策，得出：1、路堑边坡坡面冲蚀防护重点是坡率选择、边坡平台设置、边坡防护；2、路堑边坡排水重点是排水设施的合理设置与配套；并遵循有效拦截、迅速排除、衔接顺畅、防渗防冲等原则。

Caution: adding aluminized tape to a punch or cavity will most likely requiring grinding the mating half respectively.

注意： 放置铝基带到冲头或凹模型腔时，冲头和凹模在配合面处都应当粗抛光。

Highelevation and lowreliefsurface,which is preserved between large rivers in SE plateau,is generically linked to the lowrelief surface in plateau interior and shows a gradual transition to less preservation because of southeastwardly increased river incision.

虽然随着河流下切深度往南逐渐增加，残留面虽越来越少，但仍然可以识别，最终终止在雅砻江逆冲断裂带附近，该断裂带以南地区没有明显负地形特征。北东向展布的雅砻江逆冲断裂带对应着50～200 km宽的地形相对陡变带。

Not only is the present Yangtze craton constrained by regional compressional stress field but also its cold and dense lithospheric root is descended into the deep mantle by negative buoyancy, Which further strengthens inward obduction of orogenic belts surrounding it. For examples, Longmen shan mountain, Huaying shan and Bamian shan mountains override onto western margin and eastern part of Sichuan basin, respectively.

现今的扬子克拉通不仅受大区域挤压应力场背景制约，同时其冷而致密的巨厚岩石圈根正在向深部地幔下拽，从而进一步加剧了四周造山带向盆地的逆冲作用，龙门山、华蓥山和八面山分别向川西盆地和川东逆冲就是例证。

Any very large marine food and game fish of the genus Thunnus; related to mackerel; chiefly of warm waters

The major deposits in the Sanzhou ore field are related to Yanshanian or later tectonic activity,which is divisible into six sequences represented by:1the Upper Triassic-Lower Jurassic low-angle normal slip fault and associated structures near or immediately occurring on the unconformity between the Lower Carboniferous and the Upper Triassic;2the longitudinally bucking fold in Devonian-Carboniferous and Upper Triassic-Lower Jurassic strata;3the earlier phase thrusts toward northwest;4the transcurrent fault toward northeast;5the later phase thrusts toward northwest;and 6the extensional normal slip minor faults.

彭少梅 ，杨坤光，姚淑梅三洲矿田内主要矿床与燕山期或更晚的构造活动有关。燕山期构造活动可分为六个序列：1下石炭统与上三叠统不整合面附近和不整合面之上的上三叠统―下侏罗统中的低角度正滑断层及伴生构造，2泥盆系―石炭系及上三叠统―下侏罗统中的纵弯褶皱，3北西向逆冲断层，4北东向平移断层，5第二次北西向逆冲断层，6伸展性正滑小断层。

The fold cambers in plane which protrudes to the south. Regional tectonic pattern show bigger hiberarchy, which mainly is composed of roof -slippage-fault-fold. The tectonic pattern of shallow hiberarchy which includes middle-upper Triassic's fragmentary rock is fault-propagation and low-angle faults fracture, its roof rock is mainly pelyte. The tectonic pattern of midding-deep hiberarchy which includes upper Paleozoic's carbonatite is possibly thrust and broad-tempered fold.

研究区的构造样式表现出较大的层次性，总体为盖层滑脱式逆冲褶皱型，其中，以中、上三叠统碎屑岩为主的浅层次，其构造样式主要为紧密型断滑或断展褶皱低角度逆冲断裂，其滑脱面为三叠系下部泥质岩或粉砂质泥岩；以上古生界碳酸岩为主的中深层次，其构造样式推测以冲断和宽缓褶皱为主。

Results Xunhua-Guide area is characterized by step-shaped low-relief at different elevation. The low-relief surfaces developed above the newer strata in sedimentary basin among the Oligocene to the lower Pleistocene are in higher elevation, but above the older strata, are in lower elevation. The elevations of all above low-relief surfaces are lower than those of the planation surface above the bedrocks in the thrust belts. The low-relief surfaces of terraces, developed on both sides of the deep-cutting valleys within the basins, are lowest in elevation.

结果 循化－贵德地区地形形态总体呈台阶状结构，在不同海拔高度存在低起伏地形；发育于盆地沉积地层之上的低起伏面表现为年代越新的地层之上低起伏面高程越高，越老的地层高程越低，并且它们均低于发育于逆冲带基岩之上的夷平面；发育于盆地深切河谷两侧阶地之上的低起伏面海拔高程总体较低。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
