Tissue Engineering With Electric Fields: Immobilization of Mammalian Cells in Multilayer Aggregates Using Dielectrophoresis ABSTRACT: Positive dielectrophoresis can be used to create aggregates of animal cells with 3D architectures. It is shown that the cells, when pulled together into an aggregate by positive dielectrophoresis in a low-conductivity iso-osmotic solution, adhere to each other. The adherence of the cells to each other is non-specific and increases in time, and after 10–15 min becomes strong enough to immobilize the cells in the aggregate, enabling the ac electric field to be released, and the iso-osmotic buffer to be replaced by growth or other media. Cell viability is maintained. The new method of immobilization significantly simplifies the construction of aggregates of animal cells by dielectrophoresis, and increases the utility of dielectrophoresis in tissue engineering and related areas.

您好，问题已收到。
可能没五千个啦。Control theory and electricity grids theory is the electrical engineering and automation major foundation, the power electronic technology, computer technology is its main technical means, also contains a systems analysis, system design, system development and system management and decision-making, etc research field.The professional and some feature that weak electricity combining, electrical and electronic technology to combine together, software and hardware, combining with interdisciplinary nature, electric power, electronics, control, computer multi-discipline, give graduates have strong adaptability, is "the broad caliber" professional.Electrical engineering and automation to the examinee has a strong attraction, belongs to the popular major, the university entrance exam to admit fractional line often than other professional direction high, killing this lot are the main reasons: (1) the employment easy, working environment is good, the high income;(2) the name of students listen, professional content attractive; Social propaganda and public opinion guide to its advantage.The professional direction has a very good prospects for development, the research results easier to reality and product shifts, with considerable benefits.His creative thinking attracts many examinee, here is really good place to display their talent.But given the form of domestic now, examinee in enter oneself for an examination the professional when should pay attention to the following two points:(1) fully consider their interests.Maybe he could not for the sense of direction interested, but many people say, so oneself "interest".The following development is very harmful. After all, the interest is the best teacher.(2) measure their comprehensive quality.Electrical engineering and automation need strong knowledge of mathematics, physics foundation, strong language comprehensive ability, can grasp and flexible for future use professional knowledge for preparation.The professional direction of the personnel needs, but although large selection of many people, if not very strong comprehensive quality, it is difficult to get out in the crowd, outstanding achievements.Perhaps this for many bosom the examinee of lofty ambition it is unacceptable.Of course, here said the two also and whether it is feasible to the pursuit of individual students about, if a person is limited to pursuit a better job, this major is a good choice.But, if want to make breakthrough technology innovation or based on personal contribution strength as well as hard work, on the basis of the pie is never unprovoked fell from the sky.Because this major research scope, the application prospect of professional quality, graduates are relatively high, therefore employment situation very well.Our country is very need the professional direction of the talent, small to a family, to the whole society, are inseparable from these professional work.Normally, students can choose state-owned quality technical supervision department, research institute, industrial mining enterprises etc; Can also be some foreign investment, private enterprise, treatment of course is considerable.If it is strong enough, and students' ability in during study accumulated better research achievements, can completely his business, rush piece of the sky belongs.It should be pointed out that, because in the professional direction of the overseas research, so bringing preceded us if they want to have further development, establish themselves in the leading position in domestic this direction, to go abroad for further study is a good choice.希望帮到你哦！ 仅此建议，希望采纳。

4.求一篇关于电气自动化的中英文的科技文献的,大约3000字左右
摘要：本文主要介绍了近年来电气自动化技术的发展，以及应用的概况。
电气自动化技术尽管已经广泛应用与我国国民生产的各个部门和领域，但它仍需要不断革新，不断发展。关键词：电气自动化；发展；应用一、发展概况 伴随着我国的电力电子技术、微电子技术的飞速发展，电气自动化的概念已经走出了工厂，并在交通、农业、建筑、办公场所等方面得到了广泛的应用，电气自动化技术作为从电气工程技术发展出来的并与电子与信息技术紧密结合起来的一门电气工程应用技术学科，历经了近一个世纪的发展，电气自动化技术已走过了从无到有、从发展到成熟的过程。
而我国电气自动化的研究工作可以追溯到上世纪的五十年代，可以说研究的时间不短，但是它依旧焕发着生气与活力。下文就来简述一下我国电气自动化的发展历程：（一）全空型的电力电子开关。
于上世纪五十年代晶闸管出现了，它标志着运动控制的新纪元。尽管它是第一代电子电力器件，但仍被沿用至今。
随后交流变频技术出现后相继有出现了全控制式器件如GTR等。这是电力电子器件的第二代；接下来是IGBT和MGT这一类复合型电力电子器件可以称为第三代器件。
最后是功率集成电路，PIC即第四代电力电子器件。（二）由低频向高频方向发展的电路。
不断更新的电力电子器件势必要引发变换器电路的换代。当应用于普通晶闸管时，直流传动的变换器主要是整流相互控制，交流变频传动则是交—直—交变频器。
当电力电子器件转换到第二代的时候，PWM变换器采用的相应也要多些。因为采用了PWM变换器之后不仅提高了功效，并且能够减少高次谐波对电网的影响，合理解决了电动机在低频区的转矩脉动问题。
随着应用的深入，PWM也存在着诸多缺陷，因此也就有了谐振式直流逆变器电路的发展。（三）交流调速控制理论。
交流电机磁场定向远离市由德国学者F·Blaschke所提出来的，这一理论的提出为交流传动高性能控制奠定了深刻的理论基础。但他提出的这个思想远不能够达到理论的操控效果。
于是事隔14年后于1985年德国鲁德大学的Depenbrock教授又提出了直接转矩控制的思想，紧接着有将它推放到了弱磁调速的范围内。可以说他的这一控制思想新颖，控制结构简单明了，信号处理的物理概念明确，是一种高静动态性能的新型交流调速方法。
（四）通用变频器的投入使用。通用变频器：系列化、批量化、占市场量最大的中小功率变频器。
先后变频器经历了第一代：普通功能型U/F控制型；第二代：高功能型U/F型；第三代：高动态性能适量控制型。（五）单片机的发展。
占主导地位的MCS-51的8位机虽占主导地位，但是它的功能还比较简单，指令集短小，因此就有了适合大批量生产的PIC系列单片机的推广使用，它不仅具有很高的可靠性，而且保密性高。二、电气自动化的应用（一）建筑中的应用。
智能化建筑势必要引入电气自动化的成分，随着我国国民经济的飞速发展以及数字电子化科技发展，无疑，高档智能化建筑已经成为了当今建筑界的主流方向。为了达到设备的合理利用，三明的人力的节省就有了建筑设备的自动化控制系统。
例如：在建筑物供配电设计中，接地系统没计占有重要的地位，因为它关系到供电系统的可靠性，安全性。IN—S是一个三相四线J/NPE线的接地系统。
通常建筑物内设有独立变配电所时进线采用该系统。TN—s系统的特点是，中性线N与保护接地线PE除在变压器中性点共同接地外，两线不再有任何的电气连接。
中性线N是带电的，而PE线不带电。该接地系统完全具备安全和可靠的基准电位。
只要像TN—C—S接地系统，采取同样的技术措施，TN—S系统可以用作智能建筑物的接地系统。智能建筑应没置电子设备的直流接地，交流工作接地，安全保护接地及普通建筑也应具备的防雷保护接地。
智能化建筑内有大量的电子设备与布线系统，如通信自动化系统，火灾报警及消防联动控制系统，楼宇自动化系统，保安监控系统，办公自动化系统，闭路电视系统等，以及他们相应的布线系统。这些电子设备及布线系统一般均属于耐压等级低，防干扰要求高，最怕受到雷击的部分。
建立严密，完整的防雷结构。智能建筑多属于一级负荷，应按一级防雷建筑物的保护措施设计，组成具有多层屏蔽的笼形防雷体系。
（二）应用于净化空调设备。净化空调系统控制自动监控装置，可设计成单个系统的测量、控制系统，也可设计成数字计算机控制管理系统。
对温度的控制。净化空凋系统采用DDC控制。
装设在回风管（回风温度近似于洁净室温度）的温度传感器所检测的温度送往DX一9100，与设定点相比较，用比例加积分加微分运算进行控制，输出相应电压信号，控制加热电动调节阀或冷水电动调节阀的动作，控制回风温度保持在18"12—26'℃之间，使洁净室温度符合GMP要求。对湿度的控制。
装设在同风管（回风湿度近似丁洁净室湿度）内的湿度传感器所检测的湿度，送往控制器与设定湿度相比较，用比例加积分运算控制，输出电JK信号，控制蒸汽电动调节阀的动作，控制回风湿度保持在45%.65%，使洁净室湿度以满足GMP要求。电气自动化技术。
