China Engineering and the teaching has yet to fully utilize the power of MATLAB, MATLAB existing books mostly as a computer application tool there, not with the specific disciplines of organic materials combined, MATLAB GUI interface design, will be teaching content according to a certain order of the structure, using simple language, a rich display screen in front of the students. not only improes the students interested in this program, also makes some of the more abstract concepts of the past and the process of teaching students to reflect difficult to understand and master the content, through iid, image of the method explained to the students, so that students more easily understand and grasp. MATLAB and the emergence of soling this problem, MATLAB based on its powerful calculation and graphics functions so as to sole the problem, The system is controlled teaching address the dull, abstract characteristics do.

而我国工科类的教学还未能充分利用MATLAB的强大功能，现有的MATLAB书籍大都作为计算机应用工具书出现，未能与具体学科的教材有机地结合起来，MATLAB中的GUI界面设计，将教学内容按照一定的结构顺序，用简洁的文字、丰富的画面展现在学生面前，不仅提高了学生学习本课程的兴趣，还使得一些比较抽象的概念和过去教学过程中学生反映难以理解和掌握的内容，通过生动、形象的方法向学生阐明，使学生更容易理解和掌握，而MATLAB的出现解决了这一问题，MATLAB基于它强大的计算和绘图功能从而解决了这一问题，本系统就是针对解决控制教学中的枯燥，抽象的特点而做的。

And while Duncan stepped into the spotlight from day one of his NBA career, there is a certain beauty to the way Parker's game has grown over the years, so much so that it shouldn't be surprising if Parker supplants Duncan this season as the franchise player in San Antonio.

帕克成长为一个NBA球员，这是我们都梦寐以求能够做到的事情，只要我们能够有他那样的速度、那样诡异的脚步、那样…不好意思，这些字里行间又再次充满了嫉妒和羡慕。

"My character was traduced by Captain Hawkins ... so much so, that even the ship's company cried out shame".

&我的人格遭到了霍金斯船长的羞辱…以致船员们都替我觉得无地自容&。

Maybe there are not so many trashes in this town so that there is unnecessary to collect twice a week.

尽管作者说了EZ一周两次ABC一周一次，但未交代两者每次清理垃圾的数量，如果事实证明ABC公司每次都派出20辆垃圾车，一周一次就打扫的很干净，而EZ每次只派出5辆垃圾车，尽管一周两次垃圾仍清理的不干净，那么作者观点可信度将大大降低（2）即便两者清理质量相同，考虑到清理垃圾时产生的废气、噪音等负面效果，那么ABC的一周一次是不是对居民打扰更少？

School-age children into school, speech activity greatly increased, due to laughing at the people around them, and should not a good answer to the problem of learning so that children feel the pain of speech defects and increase mood and anxiety neurosis symptoms or take a negative attitude to avoid , such as children afraid to speak, but the older children did not dare to take part in more social activities, become lonely, shy, hesitant, low self-esteem and so on.

学龄儿童进学校以后，言语活动大大增加，由于周围人的嘲笑，以及不能很好地回答学习上的问题，使儿童对言语缺陷感到痛苦，加重焦虑不安情绪和神经症的病状或采取消极逃避态度，如儿童怕说话，年龄较大的儿童不敢多参加社会活动，变得孤独、羞怯、踌躇、自卑等。

Ceramic bearings can produce oxidation-ho, silicon carbide, silicon nitride and so on, diameter from 3mm-50mm, precision Machinable P0, P6, P5 level; its performance characteristics are: high temperature, oil-free self-lubricating, acid, alkali and salt corrosion , wear resistance, low noise, insulating diamagnetic, since high-speed operation; metal nano-ceramic bearing its production process for a new generation of high content of nano-particles in the heat and pressure infiltration of metal surface is activated to fill the cracks and pits the metal so that 3-5 micron metal surface is more smooth solid surface, greatly reduce the friction, improve Chennai base metals, and greatly increased the life span of bearings, and its characteristics are: long life (as an ordinary stainless steel bearings 2 -- 10-fold), low noise (as an ordinary stainless steel bearings, 70%), wear-resisting, acid, alkali, salt corrosion, high temperature, load large; ceramic bearing and metal nano-ceramic bearing design and development to meet the needs of the market for high-speed, low - noise, high load, the demand for corrosion-resistant; Machinery Production Department to produce aircraft rod end joint bearing, linear guide bearings, the fuel tank of earrings, plastic bearing, non-standard side bearing components, glass door hardware, such as high-precision control products; and provide CNC machining.

陶瓷轴承可生产氧化镐、碳化硅、氮化硅等，内径从3mm-50mm，精度可加工P0、P6、P5级；其性能特点为：耐高温、无油自润滑、耐酸、碱、盐腐蚀、耐磨、低噪音、绝缘抗磁、起高速运转；金属纳米陶瓷轴承其生产工艺为新一代的高含量纳米级微粒在热和压力的作用下被激活渗入金属表面，填补金属缝隙和凹坑，使金属表面3-5微米表面更光滑坚固，大大降低其摩擦力，提高金属的奈酸碱性，并大大提高了轴承的寿命，其特性为：长寿命（为普通不锈钢轴承的2-10倍）、低噪音（为普通不锈钢轴承的70%）、耐磨、耐酸、碱、盐腐蚀、耐高温、负载大；陶瓷轴承与金属纳米陶瓷轴承的设计开发以满足市场对高转速、低噪音、高负载、耐腐蚀的需求；机械生产部以生产机杆端关节轴承、直线导轨轴承、油缸耳环、塑料轴承、非标端轴承零部件、玻璃门控五金等高精度产品；并对外提供数控加工。

In fact, there is little pump of the fluid loss, which makes the operation of pumps can not achieve 100% efficiency, as these fluids are used to on both sides of bearing and gear lubrication, and the pump body is also not possible with no gap, it can not be so that 100% of fluid discharged from the export, so a small amount of fluid loss is inevitable.

实际上，在泵内有很少量的流体损失，这使泵的运行效率不能达到100％，因为这些流体被用来润滑轴承及齿轮两侧，而泵体也绝不可能无间隙配合，故不能使流体100％地从出口排出，所以少量的流体损失是必然的。

Tourmaline negative ions produced by micro-current, and far-infrared to improve human health and the living environment is very beneficial to use products containing tourmaline, its micro-current flow of 0.06mA can complement and balance the body's bio-electric; the dissemination of negative ions can balance the human body fluids, so that acidity of body fluids alkaline; its release could play a far-infrared expansion of capillaries to promote blood circulation, activate cells To promote the role of metabolism and so on, while blocking harmful electromagnetic radiation on the human body injury.

电气石所产生的负离子、微电流和远红外线对改善人体健康和生存环境十分有益，使用含有电气石的产品，其流动的0.06mA微电流，可补充和平衡人体的生物电；其散发的负离子可平衡人体体液，使酸性体液碱性化；其释放的远红外线可起到扩张毛细血管、促进血液循环、活化细胞、促进新陈代谢等作用，同时可阻断各种有害电磁辐射对人体的伤害。

It is determined as a result of heating facilities, regular and high-temperature heating. It operated hot water pipes so that in the 15 ℃---- 90 ℃ from time to time between the operation, resulting in accelerated aging boiler and pipe rust and scale in the United States on heating and heating from time to time out after a period of time. The purpose is to accelerate the pipeline of the scale and rust solid precipitation knot a few years later so easy to plug.

由于供热设施所决定，定时和高温供热，使热水管在15℃----90℃之间不定时运行，产生热胀冷缩加速老化，锅炉和管道中的铁锈和水垢在美日定时供热和取暖期过后停用时间，加速管道的水垢与铁锈的沉淀结固，几年后，使管理易产生堵塞。
