三将下列段落翻译成中文（3×10.0，共30分）

1. In aerobic processes (i.e. molecular oxygen is present), heterotrophic bacteria (those obtaining carbon from organic compounds) oxidize about one-third of the colloidal and dissolved organic matter to stable end products (CO2+H2O) and convert the remaining two-thirds into new microbial cells that can be removed from the wastewater by settling. Ever since the importance of wastewater treatment became recognized, municipalities and industries have relied almost exclusively on aerobic rather than anaerobic biological processes for treating their liquid organic wastes. Aerobic treatment has predominated because of its simplicity, stability, efficient and rapid conversion of organic contaminants to microbial cells, and relatively odor-free operation.

2 Wastewaters from industries include employees’ sanitary wastes, process wastes from manufacturing, wash waters, and relatively uncontaminated water from heating and cooling operations. The wastewaters from processing are the major concern. They vary widely with the type of industry. In some cases, pretreatment to remove certain contaminants or equalization to reduce hydraulic load may be mandatory before the wastewater can be accepted into the municipal system. In contrast with the relatively consistent characteristics of domestic sewage, industrial wastewaters often have quite different characteristics, even for similar industries. For this reason, extensive studies may be necessary to assess pretreatment requirements and the effect of the wastewater on biological processes.

3. Modification to the basic oxidation ditch design can be made to achieve nitrogen and phosphorus removal. The key to obtaining nitrogen removal is the proper control of dissolved oxygen levels in different sections of the oxidation ditch, and the maintenance of adequate mass of bacteria under aerobic and anoxic conditions. To meet more stringent total nitrogen effluent limits a separate anoxic channel or basin outside the ditch channels may be added. Holding mixed liquid under anaerobic conditions is required for enhanced biological phosphorus removal. This can be accomplished in either a nonaerated channel or by adding an anaerobic basin before the aerobic oxidation ditch channel.

四将下列句子翻译成英文（5×4.0，共20分）

1. 充氧池内溶解氧含量至少应保持在1.5~

2.0mg/L。

2. 在这些众多的分类中，干燥工艺随干燥剂类型而不同。

3. 表1中给出了废水处理厂三次连续反渗透试验的分析数据，这些数据用于评价在连续实验过程中，温度对分离性能的影响。

4 基于短程硝化和厌氧氨氧化的自养脱氮工艺是生物脱氮领域研究的热点，它的发现为低碳氮比废水的处理提供了新的思路。近些年来，人们陆续开发了SHARON, ANAMMOX, CANON, OLAND等自养生物脱氮工艺，进一步推动了高效、低耗脱氮技术的开发和研究。

5. 为了应对新的饮用水水质标准，传统的共沉积、离子交换、膜处理、电絮凝、吸附等技术取得了新的进展。新材料的稳定性、高选择性、廉价性是未来新技术研究与开发的重要研究方向。

The automobile engine is an internal combustion engine because the fuel (gasoline) is burned inside it. The burning of gasoline inside the engine produces high pressure in the engine combustion chamber .This high pressure forces piston to move, the movement is carried by connecting rods to the engine crankshaft. The crankshaft is thus made to rotate: the rotary motion is carried through the power train to the car wheels so that they rotate and the car moves. What do we see from the first paragraphs? ( ) The engine is source of power for a car. The engine can not make wheels go around. The engine is resource of oil. Which one Statement is true according the above first paragraph? ( ) The automobile engine is an international combustion engine. The automobile engine is an external combustion engine. The automobile engine is an inner combustion engine What do we see from the second paragraphs? ( ) High pressure is source of power inside a engine. Crankshaft is rotated without any force. Combustion chamber is not a part of the engine. Which one Statement is true according the above second paragraph? ( ) The movement of piston is carried by connecting rods to the engine crankshaft.

专业英语考试试题与答案

1.Why are cast metal sheet ingots hot-rolled first instead of being cold-rolled? Because of cold rolling is to use hot rolled steel coils as the raw material, after acid pickling to remove oxide skin for cold rolling, the finished product is hard roll, because of cold work hardening caused by deformation of continuous cold rolling hard roll strength, increase hardness, toughness and plastic index decreased, so the stamping performance will deteriorate, can only be used for simple deformation of the parts 2.What type of heat treatment is given to the rolled metal sheet after hot and “warm” rolling? What is its purpose? 轧钢的热处理的类型？轧钢热处理的目的？ Heat treatment of the main types are annealing, normalizing, quenching and tempering, solution treatment and aging treatment, cold treatment, chemical treatment, etc. Annealing： The steel is heated to a certain temperature and heat preservation for a period of time, and then make it slowly cooling, called annealing. Steel annealing is a heat the steel to the phase change or part of the phase change temperature, slow cooling after heat preservation heat treatment method. The purpose of annealing is to eliminate tissue defects, improve the organization make composition uniformity and fine grains, increase mechanical properties of the steel, reduce residual stress; Can decrease the hardness at the same time, improve the plasticity and toughness, improve machinability. So before annealing in order to eliminate and improve both the legacy of tissue defects and internal stress, and to prepare for the follow-up process, so the annealing is belong to the intermediate heat treatment, also called heat treatment in advance Normalizing： Normalizing is heated to above the critical temperature of steel, to all into homogeneous austenitic steel, heat treatment and natural cooling in air. It can eliminate hypereutectoid steel mesh cementite, for hyposteel normalizing can refine crystal lattice, improve comprehensive mechanical properties, low requirements for the parts use the normalized instead of the annealing process is more economic. Quenching: Quenching is the steel is heated to above the critical temperature, heat preservation for a period of time, then quickly into the quenching medium, the temperature plummeted, rapid cooling at greater than the critical cooling rate of speed, which is mainly composed of martensite and unbalanced heat treatment method of the organization. Can increase strength and hardness of the steel quenching, but to reduce its plasticity. That is commonly used in quenching hardening agent are: water, oil, caustic soda, and salt solution, etc

2021郑州大学英语语言文学考研经验

分数出来之后，长长地舒了一口气，虽然分数不是很高，354（66,61,112,115），但是对于我这种从计算机跨专业考进来的工科女已经算是值得歇斯底里的一个分数了。下面给大家摆摆我这半年的学习历程，说一下我得到的经验和不足。一是希望能帮助到考山大的同学，二是感谢high研APPAPP哥哥姐姐们这半年里对我的帮助，希望能把这种爱心延续下去。那种对自己没有信心的同学，大家鼓起勇气来，只要用心了，生活一定会报答你！下面我把内容简单分成了三个部分，分别是考研时间安排，课程准备，以及其他注意事项。说考研时间安排。我是从六月份开始决定考这个方向的，六月份我主要是准备资料（山大英语专业研究生方向，历年的考研真题回忆版，论坛里的各种复习资料，学姐们的复习经验，招生人数等）、买书（各种往年的规定教材、选读、基础英语的练习册），找到了一个稳定的相对比较安静的自习室、大致规划了时间安排等。几乎从七月份开始，我就正式进入状态了。七月上旬，我把两本文学简史，语言学戴伟栋和苗兴伟，做了一番浏览，也就是速读，对其做了一个简单的概要。七月下旬，我就开始做笔记了。做笔记的过程一直持续到高级英语讲座开始（11月4号）算是正式完成，11月12月两个月的时间不停地背笔记、提炼、自己理解，法语做练习。复习过程一直持续到入考场前的最后一秒，我还在背语言学的terms。课程准备。先说专业课。专业课复习起来非常辛苦，尤其是我当时对这个专业几乎没什么深入地了解，只是凭热情一心要学英美文学。专业课我就是做笔记，背诵，但是最重要的过程还是自己思考和提炼的过程。主要参考了规定的教材，另外还看了学习指南，环球的专业课参考书，陈嘉的英国文学简史，还有部分重点作家比如莎士比亚参照了诺顿。整理的过程非常辛苦，已经不记得崩溃过几次了。大家根据题型安排好时间，文学术语也不要忘记整理（我就是十二月才想起整理文学术语，所以答的不好）。语言学戴伟栋和苗兴伟的我都有看，但是戴伟栋的我是暑假看了一遍然后做的笔记，背诵还是背的苗兴伟的。关于专业课，不得不说11月上旬的那个高级英语讲座还是比较有用的，老师会说一些具体的答题方法，建议大家去参加。十一过后给山大外院打电话问问就可以了（PS，我不是这个辅导班的
