By means of scanning electron microscopy , transmission electron microscopy and X-ray diffraction techniques, microstructure of spray-deposited hypereutectic Al-Si alloy was analyzed.

本文以过共晶Al-Si合金为研究对象，在对喷射沉积合金凝固过程分析的基础上，重点研究了合金的微观组织与力学行为，讨论了后续热挤压和热处理对喷射沉积合金微观组织和力学性能的影响。

Result The CTA of vertebral artery can find all kinds of abnormal ,example hypogenesis stenosis,formation of atheroselerotie plaque and calcification,and press by surrounding tissue, and affect the blood stream of vertebral artery directly.

结论椎动脉CTA可以发现椎动脉的先天狭窄、管壁内粥样斑块形成及其钙化，以及受周围组织挤压，均能引起TIA。

Forces of 15 g for the fine root of a lower incisor and 60 g for a molar are sufficient for slow extrusion.

部队的15政的细根的门齿，并降低60克的摩尔有足够的缓慢挤压。

And the company is the first one entitled to draft out the standard of low pressure casting line, which is a professional manufacturer of special casting equipment including low-pressure die casting machine, differential pressure die casting machine, extrusion die casting machine, inclinable gravity casting machine, air tight tester, air-elimination refine machines, hydrogen-test machines etc.

主要从事低压铸造机、差压铸造机、挤压铸造机、可倾式重力铸造机、气密性试验机、除气精炼机、测氢仪等热加工专用及辅助设备的生产。

Driving toothed gear precision forgings have been successfully produced by compound precision form ing technology combined waFln forging of blank with cold extrusion not only with high surface cleanness,dimension accuracy and small post machining of outer surface but also the indention inner gear formed by cold extrusion can be put into use without post machining,with notable energy saving and material saving and economic benefit.

精锻件不仅表面光洁、尺寸精度高、外表面的后续加工余量小，而且冷挤压成形的锯齿状内齿无需后续加工就可以装配使用。因此，精密成形具有显著的节能、节材效果，经济效益十分显著。

The influence of indentor radius on the plastic deformation has been discussed and some important results are as follows:(1) The influence of the ratio of ceramic coating thickness to indentor radius on the failure of coating, plastic deformation of substrate and crack propagation are obvious.(2)The propagation of crack in ceramic coating is assumes to be of semi-elliptical shape under normal contact with a rigid sphere.(3)Fatigue life of ceramic coating is mainly decided by substrate and load, the lower substrate elastic moduli and load, the more cycles of fatigue.

分析了压头半径对塑性变形的影响，模拟结果表明；(1)陶瓷涂层厚度和压头半径之比对涂层失效、基体塑性变形及裂纹的形成有显著影响；(2)在刚性球压头静态挤压条件下，陶瓷涂层中的预制裂纹按照椭圆形裂纹规律扩展；(3)陶瓷涂层的疲劳寿命与基体和载荷有很大关系，基体弹性模量越小，疲劳寿命延长。

The limited hydrothermal karst and mixed zone beneath the anticline axis controls the porosity distribution of Ordovician System and it is anticipated that surroundings of the axis of fold formed by compressional reverse orverthrusting during Indo-Chinese epoch and the coordinated area of morphology of anticline in the screen of buried hill and that of top surface morphology is the best position for development of the reservoir.

局限的热液岩溶和裸露的背斜轴部之下的混合带对千米桥潜山奥陶系孔隙分布具有重要控制作用，预期在印支期挤压逆冲作用形成的背斜轴部，特别是潜山内幕背斜形态与潜山顶面形态相互协调的区域，应是储层发育最好的部位。

If you'd prefer instead to build a more old-fashioned, standard Big Bang universe, you'll need additional materials. In fact, you will need to gather up everything there is—every last mote and particle of matter between here and the edge of creation—and squeeze it into a spot so infinitesimally compact that it has no dimensions at all.

你最好造一个老土一点的大笨宇宙，你必须搜集点另外的原料，实际上，你得把所有的东西都搜巴到一块——每粒灰尘，边边角角的微粒——然后把它挤压到一个小得没有面积得污点样的东西里。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
