Cabrera is, at least, an ideal fourth outfielder. He is an above-average runner and defender with a well-above-average arm, plus he is a switch-hitter with a good eye. Last year he capably filled in for a stretch and did it with infectious enthusiasm.

Cabrera是个理想中的第四外野手，有著中上程度的跑垒及防守能力，也有著一副强肩，更是个拥有优异选球能力的左右开弓打者，去年球季他适时填补了球队的空缺，对比赛也展现出了极具感染力的热情，唯一让他还无法站上先发位置的疑虑，就是Cabrera是否能继续提升自己的power，他能办到吗？

The research work of this paper is divided into five parts: The first ,according to the work characteristics of ship's auxiliary boiler, this paper is to design applied project in the automatic control system of ship's auxiliary boiler; The second, according to the work request of the cargo winch of alternating three-speed change-pole speed-adjusting, this paper is to determine adopting the method of the PLC control; The third, this paper is to design PLC application in three -phase induction motor control, to give the ladder chart, program and input and output circuit diagram; The fourth, this paper is to research the method of the ship's combined starting screen automatic control with the PLC; The fifth, this paper is to inquire the possibility of apply the PLC in ship's engine room surveillance system; According to the comprehensive analysis of above actual example of ship's auxiliary machinery automatic system with the technique of PLC; not only can use the technique of PLC to replace traditional relay-contactor control technique in ship's auxiliary machinery automatic system, but also can get the conclusion of the former is more dependable and more clever than the latter, the maintenance is more convenient, thus develop a new path for ship automation.

本文研究的工作主要包括五个部分：第一，根据船舶辅锅炉的工作特点，设计PLC在船舶辅锅炉自动控制系统中的应用方案，主要有PLC选型及输入输出点的设计，画出系统控制梯形图并分析工作原理；第二，根据交流三速变极调速起货机的工作要求，确定采用PLC控制的方法，进行控制系统的硬件设计和软件设计，并分析工作原理：第三，设计了PLC在三相异步电动机控制中的应用，给出了控制梯形图、程序及输入、输出接线图；第四，研究了用PLC实现船舶组合起动屏自动控制的方法，进行了系统的电源设计和软件设计，给出系统工作流程图；第五，探讨了船舶机舱监视系统应用PLC的可行性，将继电器报警线路改为用PLC控制报警，给出系统硬件图和软件梯形图，并分析了PLC机的选型、抗干扰和应用PLC的经济效益和社会效益等问题。综合以上船舶辅助机械自动控制系统采用PLC技术的实例分析，可以得出船舶辅助机械自动控制系统不但可以使用PLC技术取代传统的继电器接触器控制技术，而且前者比后者更可靠、更小巧，维护保养更方便的结论，从而为船舶自动化开辟了一条新的路径。无忧毕业设计网 www.5ubs.cn

The second one is vague and depressed, heavyhearted and melancholy such as Hetangyuese and Jiangshengdengymlideqmghuaihe.There are four aspects that consist of the style of language rhythm in Zhu Ziqings proses: Firstly, image language description shows the style of language rhythm and coincide with his subtle feelings.

朱自清散文语言的音乐美表现在四个方面：一是表现在他散文的意象性语言的描绘中，朱自清极善于把意象化的画面转换同主观情绪、情感的变化有机揉和在一起，使读者感受到一股含蓄深隐的情绪、情感之流，听到源于作者灵魂深处的心灵之声。

The results indicated that the concentration of Cu in the soil is 220.16 mgkg^(-1) contrast to the CK 500.31 mgkg^(-1) significantly decrease when the concentration of EDTA in the soil is 2 mmolkg^(-1) that explains EDTA treatment significantly decreased soluble Cu content in soil because of translating into Cu of water distill floating on the surface of soil and most accumulating around root. Contemporary, application of EDTA to the soil significantly enhanced mobilization of Cu in soil and increased Cu uptake in shoot of Leersia hexandra Swartz., the highest concentration in the leaves 336.54 mgkg^(-1) is 4 times higher compared with the ck 80.34 mgkg^(-1). However, citric acid, oxalic acid and malic acid inhibited mobilization of Cu and less significantly affected shoot Cu accumulation.

结果表明，当向土壤中施加质量摩尔浓度为2mmolkg^(-1)的EDTA时，土壤中Cu质量分数为220.16mgkg^(-1)与空白土壤中500.31mgkg^(-1)相比明显减少，说明EDTA可以极显著的降低土壤中的铜质量分数，使其转化成水提取态的Cu浮于土壤表面，并大部分聚集在根部周围，同时向土壤中施加EDTA不但促进了对Cu的活化而且显著提高了李氏禾对Cu的吸收，叶中最高质量分数达到336.54mgkg^(-1)是对照中80.34mgkg^(-1)的四倍；而柠檬酸、草酸和酒石酸则抑制了Cu的活化，但对李氏禾地上部分的Cu质量分数影响不大。

Through the topographical survey, literature research and analysis of the remote sensing images, we shall emphasize on the five factors of water conservancy, water flow, streams, water retaining and water utilization in the upper reaches of the river, which are interacted and interplayed.

研究结果表明，漓江为雨源性河流，降雨时空分配极不均匀，70%的降雨量集中在漓江上游区域，全年62.7%降雨量和降雨时间集中在四个月内(即4～7月)，最大的日降雨量可达415.8mm；降雨量最小的月份出现在12月至翌年1月，仅100～110mm，占全年降雨量的6%左右，由此直接影响流域河川径流季节性的变化，造成洪水期和枯水期现象，周期性水量的变化是不为人们意志改变的一种自然规律。

The nature of man and life is intuit; man's different intuits of the universe and life lead to four different life states, and the transcendent state is the best one that an ideal life could reach, which is also that of a sage. The transcendent way to be a sage is "To be wise but through a mediocre way".

人及人生的本质是觉解，人生的意义因觉解不同而不同，人对宇宙人生不同的觉解形成四种不同的人生境界，天地境界是理想人生所能达到的最高境界，也是圣人的境界，实现成圣的超越之路就是&极高明而道中庸&。

Jakarta was still a sleepy backwater in those days, with few buildings over four or five stories high, cycle rickshaws outnumbering cars, the city center and wealthier sections of town—with their colonial elegance and lush, well-tended lawns—quickly giving way to clots of small villages with unpaved roads and open sewers, dusty markets, and shanties of mud and brick and plywood and corrugated iron that tumbled down gentle banks to murky rivers where families bathed and washed laundry like pilgrims in the Ganges.

雅加达在那时仍是穷乡僻壤，很少有楼层高过四五层，三轮黄包车比汽车多得多，城市中心和市镇中比较富有的地区——带有殖民时代建筑的高雅和豪华，得到精心照料的草坪——极快地被密集的小村落占据了，包括，没有铺石砖的路径，未封闭的下水道，多尘的市场，泥浆、砖、夹板和瓦垅钢皮建成的棚屋，坐落于不太陡峭的堤岸上，建筑下是混浊的河水，人民在河里洗浴、洗衣服，就像印度人在恒河的生活一样。

Such doubts havesitimulated the researchers'curiosity and start to explore the students' terms This research proceeds by observation interview test using learning sheets and etc The purpose is to explore students' terms of scientific concepts sources of terms connections between students' usage nomenclature and chooses of usage The results of the research are as follows: 1 There are five kinds of naming principles for students' terms of scientific concepts: appearance habit function replacing and sound Appearance principle contains three categories: color shape and partial construction; habit principle contains custom and ability; replacing principle contains reality and non-reality 2 Students' terms of scientific concepts come from two ways: self-acquisition and learning through senses The former way is only a bit more common than the latter 3 There are three different relationships between students' usage of terms and nomenclature: one both the same in usage and meaning; the other both different; another different usage but the same meaning Normally terms that students used are various from nomenclature in the aspects of usage and meaning only a few would match and even rare for "Synonyms" to occur 4 Alternative options for students' scientific terms are maintenance adaptation or co-existence with formal scientific terms The most common way of selecting usage of terms is to maintain Sometimes students would adapt themselves once learn of scientist's term However some believe that very odd chances for both could exist at the same time

这样的疑问深深引起研究者的好奇，著手探索学生科学概念所使用的语言。本研究透过观察、访谈、学习单施测等方法来进行，目的在探讨学童在科学概念上所使用之学生惯用语、学生惯用语来源、学生惯用语与科学家用语之关联性、学生惯用语选择。研究结果如下：一、学童在科学概念上所使用之学生惯用语的命名原则有五种：外型、习性、功能、藉代称呼及声音，其中外型原则有颜色、体型及部份构造三类目，习性原则有习惯及能力两类目，藉代称呼原则有实体及虚拟两类目。二、学童在科学概念上所使用之学生惯用语有两种来源，分别为自己称取和听来。学生惯用语来源较多为自己称取，透过其他方式听来少一点，但两种来源的比率差距甚小。三、学童在科学概念上所使用之学生惯用语和科学家用语的关系有三种，分别为用语意涵均相同、用语不同意涵相同和用语意涵均不同。学生惯用语通常和科学家的用语是不同的，且其意涵也不同，只有部份学生惯用语和科学家用语意涵均相同，至於学生惯用语和科学家用语不同但意涵相同的极少。四、学童的科学概念相关学生惯用语选择有三种，分别为维持学生惯用语、改变成科学家用语和科学家与学生惯用语皆可。学童的科学概念相关学生惯用语选择，以维持学生惯用语最多，而有些时候学生会在得知科学家的用语后改变成科学家用语，但认为科学家用语和自己使用的学生惯用语皆可的则很少。
