摘要修改
根据流体力学以及流体动力学的基本理论可知，此漩涡区对于消能具有积极作用，然而，定量的分析漩涡区的形成可以看到，在漩涡区的中心水流的速度近似为零，形成流动滞止区(stagnant area)，这样的特点对保持流道始终通畅具有明显的不利。因为灌水器在实际使用时，其内部流动并不是单一的流体－水，而是含有由于过滤不掉的固体的颗粒，并且由于使用中水肥往往同步供给，肥料固体不能完全溶解，还有盐类的结晶也会造成水中含有固体颗粒。当这些颗粒运动到这些漩涡区极易在此处沉积下来，这就是造成堵塞的根本原因。
According to hydrodynamics theory, the vortexs are benefit for (beneficial to) energy dissipation. But through the quantitative analysis on the establishment(forming) of the vortex, in the center of vortex the velocity(当只考虑其速度大小而不论及方向时，仅用speed 即可，否则应用velocity) is zero and at this zone (in this region)the velocity(speed) is very low which will form stagnant area(so, a stagnation zone will form therein ). And this characteristic(?) is obviously not benefit for(beneficial to) unblocked of channels(?). Because the liquid in emitters is not single(?) liquid-water(??) in practice. The liquid consist of(由。。。组成和含有的区别？)) solid grain which cannot be filtrated and indiscerptible（不可溶的，insoluble） fertilizer(颗粒肥料,granulated fertilizer) and the crystal of salt kinds(盐类晶体，salt crystals). These grains can desposit(拼写错！) when they move to the stagnant areas forming the clogging of emitters. 参考译文：
It is known from the basic theory of fluid mechanics and hydrodynamics that
vortexes are beneficial (advantageous, favorable )to energy dissipation. However, through quantitative analysis on the forming of vortex, it is discovered that in the center of vortex, the flow speed of water is approximate to zero and in the nearby region, the flow speed is also very low. So, a stagnation zone is formed, which is obviously not beneficial to the free passage of channels(流道通畅). Because the medium inside the micro-channel is not merely the water, there are also some small solid grains evaded from the filter screen（漏网的） and insoluble granulated fertilizer as well as some salt crystals. When these particles move to this stagnantion zone, they are apt to( be apt to….有….倾向) deposit, leading to the clogging of emitters.
高速旋转机械动平衡问题的一篇文章摘要：
Abstract: Most high-speed rotating machineries operate at a speed higher than their first critical speeds. Since there are two different modal shapes existing in rotors before and after(under and over )that speed, most currently used balancing techniques for rotors require two steps to fulfill the balancing purpose. Firstly, a traditional low-speed rigid balancing is performed, and secondly, a high-speed balancing procedure is carried out. This high-speed balancing procedure is very complicated and dangerous, it needs a large number of test runs and causes corresponding wastages as well. This paper develops a novel balancing method, called Low-Speed Holo-Balancing (LSHB), which can balance a flexible rotor without test runs at high speeds. The principle of LSHB is mainly based on the holospectrum technique, which will be illuminated in detail at the end of this paper. Instead of using information from a single sensor, through a multi-sensor fusion(?)a three-dimensional holospectrum is constructed to describe the vibration response of a rotor vividly and accurately. LSHB can easily balance the flexible rotors at lower speeds than the first critical speed, according to the decomposition results of holospectrum. Because LSHB needs not (语法错误！在否定句中，need 已不是实义动词，只能作助动词用，故不能加“s”,而若作实义动词则须在它前面加does not ) any test runs at or higher than the first critical speed like any other traditional balancing techniques do, the balancing procedure is much more safe(又是语法错！safe 的比较级是safer 而不是more safe), and economical. The key points and main operating steps of LSHB will be presented. The results of experiments(最好用experimental results) held(conducted) on a flexible-rotor(这样就变成一个形容词作实验台的定语了) test rig(实验台) validated(一定要用过去时表示已经验证了) the effectiveness of this method.

企业资源计划中基于QFD的经营规划问题的初步研究
Strategic Planning based on Quality Function Deployment in Enterprise Resource Planning(ERP)
随着全球化的竞争的日益加剧，企业必须实行战略管理，提高企业的核心竞争力，为企业赢得持续的竞争优势，从而在激烈的市场竞争中立于不败之地。战略规划是进行战略管理的一个主要过程，是企业为了实现长期的经营目标，充分、有效地利用各种资源和能力，以适应多变的外部环境而制定的指导企业运营活动的总计划。企业资源计划（ERP）则是企业优化资源配置，改善业务流程，增强综合竞争力的重要手段，研究ERP中的战略规划问题具有重要意义。
With the global market competition becoming more and more severe, it is necessary for enterprises to carry out strategic management and enhance its core competitiveness so that they can gain(obtain) sustained(sustained,持久不断的，不衰减的.e.g. ～current持续电流，～load 持久载荷；sustainable, 可持续的. e.g. ~development 可持续发展。) competitive advantages and finally win(succeed) in the market competition. Strategic Planning (SP) is not only the primary process in carrying out an enterprise’s strategy management but also is the topmost planning, which is to realize the enterprise’s long-term objective, make full use of its resources and capabilities and adapt to the variational (varied, changeful，changing) external environment. Enterprise Resource Planning (ERP) System is a powerful means to optimize an enterprise’s resources collocation (configuration), improve operation flow and enhance its comprehensive competence.
