Internet-----外文翻译（全文）

The Internet also known as the Net is the world's largest computer network . “ And what is a network”? You may ask. A computer network is basically a bunch of computers booked together somehow. In concept, it's sort of like a radio or TV network that connect a bunch of radio or TV stations. ..
数控机床上探测器应变的工具-------外文文献翻译（原文+译文）

摘要在数控机床中刀具探测器是非常重要的。在现代工业中探测器的应用及缺点。按照起初的想法，在切削刃的四个方向： + X，-X， + Z和-Z定向刀具磨损的直接测量中全部使用应变桥。关键词：探针，应变式传感器，刀具磨损的测量，直接测量刀具磨损。1引言各领域制造技术的快速发展，以降低成本，提高精度和缩短生产..
低电压开关设备的电压特性分析和测试系统的设计-----外文翻译

Abstract - The test of low-voltage switchgear (contactor,relay, breaker etc.) includes electric longevity and electriccharacters of turn on-off. The fast calculation and analysis methods for electric parameters were investigated. Muchattention has been paid to the effect of performance in lowvolt..
公司金融的理论与实践：来自实地的证据----外文翻译（原文+译文）

关于资本成本、资本预算和资本结构问题，我们调查了392位首席财务官。大的公司主要依靠现值技术和资本资产定价模型，而小公司相对地比较喜欢使用回收期标准。当发行债务时，公司比较注重维护财务弹性和比较好的信用等级；当发行股票时，比较注重每股收益稀释和近期股票价格升值情况。我们发现了对于支持优序融资假说和交..
土木工程外文翻译

适当有效的建筑材料是限制富有经验的结构工程师成就的主要原因之一。早期的建筑者几乎都只使用木材，石头，砖块和混凝土。尽管铸铁在修建埃及的金字塔中已被人们使用, 但是把它作为建筑材料却由于大量熔炼它比较困难而被限制。藉由产业革命，然而，受到把铸铁作为建筑材料和在大量融炼它的能力的两者对其双重需要的影..
孔隙水压力作用下土坡的极限分析-----外文翻译

ABSTRACT: the limit-equilibrium method is commonly, used for slope stability analysis. However, it is well known that the solution obtained from the limit-equilibrium method is not rigorous, because neither static nor kinematic admissibility conditions are satisfied. Limit analysis takes advant..
复杂光学曲面慢刀伺服超精密车削技术研究

自由曲面光学元件具有许多优异的光学性能，越来越多地应用到现代光学系统设计中。而自由曲面光学元件制造的复杂性和不确定性是制约其应用的瓶颈之一。慢刀伺服单点金刚石车削是一种可以加工很高精度自由曲面光学表面或非回转对称光学曲面的新技术。机床伺服执行能力是自由曲面能否加工的基本条件。金刚石刀具几何参数的..
计算机程序-----外文翻译

Computer Program, set of instructions that directs a computer to perform some processing function or combination of functions. For the instructions to be carried out, a computer must execute a program, that is, the computer reads the program, and then follow the steps encoded in the program in a ..
从非饱和土力学的角度，土石坝材料的特性-----外文翻译

Abstract ：The basis of the design of earth and rockfill dams is focused on ensuring the stability of the structure under a set of conditions expected to occur during its life. Combined mechanical and hydraulic conditions must be considered since pore pressures develop during construction, after..
