现代工程机械行业的技术进步(中文4700字,英文2600字)
大型机械式挖掘机在目前国际国内在矿山开采及工程施工中有着广泛的应用，其性能的优劣对生产率有很大的影响.在国际市场竟争日趋激烈的今天，如何提高产品的质量是提高其市场竞争力的关键。
    目前，我国的大型机械式挖掘机在设计水平，设计手段及产品质量上与国外同类产品相比尚有较大差距.国外已经将人一机一环境作为一个系统统一考虑，提倡低振动、低噪音的绿色设计，将现代设计方法(电子模拟理论、动态设计、可靠性设计等)普遍地应用于挖掘机设计，使产品设计现代化，性能可靠。而我国仍然主要采用传统的仿型设计，而近年来才将现代设计方法逐步应用到挖掘机的设计上，但在这方面工作开展的不得力，主要表现在自行设计开发能力不够，基础工作做得不完善，尤其在挖掘机动力学方面。

英文原文
 Modern construction machinery industry of technical progress
Large-size mechanical mining excavator is used widely in international and domestic engineering construction and mining performance, and its property defines the efficiency much.Now because the international market is opened step step, how to promote the quality of excavator is the key that a factory reinforces its competing force.
In our country，the designing elevation and production quality on excavator can not keep up with international advanced technology applying on excavator.Now the advanced technology has already applied advanced designing method on excavator designing，such as electronic simulating theory，dynamic design， reliability design and so on.But in our country ,the most excavator design has still applied the traditional design method ,the modern design method has not began to be actually applied .The prime display is that the capability of self-design is not enough and the basic work has not done perfectly especially the excavator kinetics .
