电子邮件地址：iltonlb@,rcsfreire@alessiot@silvanacunhacosta@摘要：本文提出了一款低成本的小型可变频信号发生器。
该发生器采用串行通信方式，在实际的应用中通过对失聪人员的实时触觉反馈对其进行模式训练。
这个信号发生器是用于修正数字化去电流延迟及对实际的声音信号进行处理。
通过使用该信号发生器，我们将用于触摸端用以生成数字化信号的部分从接收模块中分离出来。
关键词——耳聋，音高，信号发生器，触觉感知。
I 介绍大约在五十年以前，Geldard提出触觉是一直“被忽略的通讯感知”[1]。
他指出虽然视觉系统和听觉系统分别在空间区隔及时间区隔时候利于信息的传递，而人体本身的感觉系统则在两种情况下都可适应。
另一方面，在无法听到也无法看到的情况下，触觉就变得非常关键了。
在Geldard之前有人曾试图用触觉作为一个通信联络的方式。
从XX世纪以来，人们就开始研究对失聪人员采用触觉系统进行声音信号的传递。
人们尝试寻找各种各样的信息转换的方式，并且由此开发出了许多触觉感知装置来帮助失聪人员。
[3]，[4]，[5]在文献[6]里面，触觉感知编码是以葡萄牙语文本开发的，它应用于用来辅助语音教学的音节游戏中，其中设置了以触觉感知为基础的语音参数的转换系统。
这些转换装置在传输感知实验中验证了基准语音频率和元音音节的触觉感知。
但这种转换装置没有被采用在实时系统当中。
由于是触觉感知，为了有助于对基准频率控制的训练，系统没有设置对应于实时系统的寄存器。
但不管怎样，装置中任然设计了帮助通过触觉感知的信息传输来进行语音朗读的系统[7][8][9][10]。

电子信息工程电路编程中的AT89C51单片机译文标题电路编程中的AT89C51单片机AT89C51 In-Circuit Programming 原文标题作者Robert W.Sparks等译名国籍美国斯帕克等W.罗伯特Atmel Corporation原文出处摘要本应用说明的是ATMEL公司AT89C51的电路可编程闪存的微控制器。
为在电路可编程AT89C51的应用提出了与应用程序相关的例子，它的修改要求支持在线编程。
这种方法显示在该应用程序中的AT89C51单片机可通过商业电话线远程改编。
本应用笔记中描述的电路，仅支持5伏电压下编程，需要使用一个AT89C51-XX-5。
标准A T89C51的需要12伏电压。
该应用程序的软件可从ATMEL下载。
总论当不在进行程序设计的时候，在电路设计中的AT89C51设计将变得透明化。
在编程期间必须重视EA/VPP这一脚。
在不使用外部程序存储器的应用程序中，这脚可能会永久接到VCC。
应用程序使用的外部程序存储器要求这一脚为低电平才能正常运行。
RST在编程期间必须为高电平。
应该提供一种方法使得电路通入电源以后，使RST代替主要的复位电路起到复位的作用。
在编程过程中，PSEN必须保持低电平，在正常运行期间绝不能使用。
ALE/ PRO在编程过程中输出低电平，在正常运行期间绝不能使用在编程过程中AT89C5I / 端口是用于模式应用程序，地址和数据选择的，可能要该控制器从应用的电路隔离。
如何做到这一点取决于应用程序输入端在编程过程中，控制器必须与应用电路的信号来源隔离。
带有三个输出状态的缓冲区在应用程序之间插入电路和控制器，同时在编程时缓冲区输出三种状态。
一个多路复用器用于信号源之间进行选择，适用于任何一方的应用电路或编程控制器电路的信号输出端如果应用的电路可以允许端口在编程过程中的状态变化，则不需要改变电路。
如果应电路的状态，必须事先在编程过程中的保持不变，可能在控制器和应用电路中插入锁存。

Field-programmable gate array(现场可编程门阵列)1、History ——历史FPGA业界的可编程只读存储器（PROM）和可编程逻辑器件（PLD）萌芽。
可编程只读存储器（PROM）和可编程逻辑器件（PLD）都可以分批在工厂或在现场（现场可编程）编程，然而，可编程逻辑被硬线连接在逻辑门之间。
在80年代末期，为海军水面作战部提供经费的的史蒂夫·卡斯尔曼提出要开发将实现60万可再编程门计算机实验。
卡斯尔曼是成功的，并且与系统有关的专利是在1992年发行的。
1985年，大卫·W·佩奇和卢文R.彼得森获得专利，一些行业的基本概念和可编程逻辑阵列，门，逻辑块技术公司开始成立。
同年，Xilinx共同创始人，Ross Freeman和Bernard Vonderschmitt发明了第一个商业上可行的现场可编程门阵列——XC2064。
该XC2064可实现可编程门与其它门之间可编程互连，是一个新的技术和市场的开端。
XC2064有一个64位可配置逻辑块（CLB），有两个三输入查找表（LUT）。
20多年后，Ross Freeman 进入全国发明家名人堂，名人堂对他的发明赞誉不绝。
Xilinx继续受到挑战，并从1985年到90年代中期迅速增长，当竞争对手如雨后春笋般成立，削弱了显著的市场份额。
到1993年，Actel大约占市场的18％。
上世纪90年代是FPGA的爆炸性时期，无论是在复杂性和生产量。
在90年代初期，FPGA的电信和网络进行了初步应用。
到这个十年结束时，FPGA行业领袖们以他们的方式进入消费电子，汽车和工业应用。
1997年，一个在苏塞克斯大学工作的研究员阿德里安·汤普森，合并遗传算法技术和FPGA来创建一个声音识别装置，使得FPGA的名气可见一斑。
汤姆逊的算法配置10×10的细胞在Xilinx的FPGA芯片阵列，以两个音区分，利用数字芯片的模拟功能。

相比较于之前常规的迈克耳孙干涉仪,我们使用一个空心回射器而不是一个平面反射镜的反射镜。
本文将为大家介绍实验设置和长度测量的结果。
关键词：飞秒线性加速器，长度串，干涉仪，空心回射器1 介绍最近关于电子脉冲压缩的实验产生高峰值电流和亮度飞秒电子串。
关于短束源自于高质量光束的潜在应用要求这方面一起了广泛兴趣。
高质量的核物理加速器,自由电子激光器驱动加速器,下一代线性对撞机,第四代光源都需要短时间光束脉冲。
同时,在进程中对诊断的短电子串的研究也起了重要作用。
有几种已经使用或正在开发的方法去测量短电子串的长度。
这些一般分为两类:频域方法和时域方法。
众所周知，在时域测量长度的方法中使用条纹相机，条纹相机已经证实是限于串长度超过200 fs ，此外,条纹相机昂贵并且测量系统复杂。
相对于时域测量方法，频域测量使用相干过渡辐射(CTR )从金属箔在测量飞秒脉冲的短电子中已经显现出前景。
本文我们首先从短电子串方面给出了基于一代的高强度相干渡越辐射的理论和试验研究,然后讨论该方法基于相干渡越辐射测量束飞秒的长度,并从改进电子实验装置给出了串长度测量的结果。
最后,我们分析了空气湿度对串长度测量的影响，并且阐释了对未来研究的计划。
2 理论背景2.1 相干渡越辐射源自于相对论性电子串辐射如同步加速器辐射跃迁辐射等，本质上有较广的范围，如果辐射的波长短于电子串长度，这个阶段的辐射电子不同于彼此，所以辐射是不连贯的。
另一方面,如果波长较长的串长度，辐射是连贯的并且辐射强度的平方成正比每串数字电子。

The chip was fabricated by standard 1-photomask with low cost method. The device consists four reservoirs, four channels and one open region which contain a cell retention chamber. Reservoir one was used for cell introduction and washing, whereas reservoir two was used for reagent delivery. Reservoir three and four were used as waste reservoirs. By using this chip, they quantified dynamic Ca2+ mobilization of a single cardiomyocyte during its spontaneous contraction. Also, they monitored successfully dynamic responses from various external stimulation such as daunorubicin (cardiotoxic chemotherapeutic drug), caffeine, and isoliquiritigenin (herbal anticancer). Their results also prove that anticancer drugs have less effect on the Ca2+ of the cardiomyocytes. This device has quantified the cellular response of single cardiomyocytes, discovery of heart diseases drug and cardiotoxicity testing.In 2010, Mellors et al. [95] proposed an electrophoretic and electrospray ionization based microfluidic device for single cell analysis. The device was fabricated on corning borosilicate glass substrate by using standard photolithography and wet chemical etching technique. Figure 12 shows the schematic of the microfluidic device, where A was a cell loading reservoir and B was buffer loading, which intersects with the separation channelThis intersection zone was a cell lysis zone. CS was an electro-osmotic pump which was connected with an electrophoretic separation channel and electrospray orifice. Cells can flow throughhydrodynamically or electrically to the intersection zone, where cells were electrically lysed. Then, cells can migrate to electrospray orifice through the separation channel where cells electrospray ionization occurred. This device successfully lysed human erythrocytes with real-time electrophoretic separation. The heme group, α and β subunits of hemoglobin were detected from erythrocytes when cells were continuously flowed through the device. This device can analyze 12 c/m.Localized single cell membrane electroporation can provide better cell transfectionwith micro/nanofluidic devices compared to single cell electroporation (SCEP) or bulk electroporation (BEP). Because of micro/nanoscale electrode dimension and distance between two electrodes were very small, as a result, electric field can intense in a very small region of the cell membrane compared to single cell dimension. Thus, the local area of the single cell can be affected by a strong electric field, whereas other areas will be unaffected. Due to the effects of small areas of the whole single cell, high cell viability and high transfection rate can be achieved compared to single cell electroporation. However, Boukany et al. show localized single cell electroporation by using nano-channel based ion transportation using electrophoresis method with two large electrodes [30]. By fabricating micro/nano electrodes with a micro/nano scale electrode gap, this device can provide some promising parameters such as low voltage and power requirement, lower toxic effect due to negligible ion generation, small sample volume and negligible heat generation. These parameters are essential to achieve high transfection rate and high cell viability. Thus, microfluidic based LSCMEP process can provide a better understanding to analyze intracellular cytosolic compounds compared to SCEP or the bulk electroporation process. Nawarathna et al., demonstrated the AFM based LSCMEP process. Figure 13 shows localized electroporation of a single cell using atomic force microscopy (AFM) technique [29]. For this experiment, they modified AFM tip to act as a nano-electrode to make an intense high electric field near the localized area of the single cell membrane. A boron doped silicon AFM tips (σ = 0.001 Ω cm, k = 1.5 N/m) was used for LSCMEP process. Before electroporation, the tip was grown with 20 nm SiO2 layer and finally this oxidized tip was sectioned until bare silicon was exposed by focused ion beam (FIB) technique. As a result, a smaller area of bare silicon can cause an intense high electric field on a single cell membrane. They have reduced this bare silicon area down to 0.5 μm in diameter, which was concentrated with an intense electric field on 10 μm diameter of rat fibroblast cell. Figure 13a–h shows the results of LSCMEP technique using AFM tip for electroporation process and Figure 13i demonstrated the AFM tip, which was positioned on top of the single cell for localized single cell membrane electroporation (LSCMEP) process. To make an intense high electric field, 1Vpp with0.5 Hz pulse was used to transfect rat fibroblast cells. The transfection of single cell was completed within 10 s. This device can perform highly localized electroporation of a sigle cell with concentric electric field on local area of single cell membrane. The experiment can be performed in a friendly environment such as cell culture dishes, etc.In recent years, Boukany et al. [30] showed nanochannel based localized single cell electroporation with a precise amount of biomolecules delivery. In this device, they positioned a single cell in one microchannel by optical tweezers and transfection agent was loaded to another microchannel. These two microchannels were connected by one nanochannel. To apply a very high electric field in between two microchannels, a transfection agent was delivered through the nanochannel using an electrophoretically driven process and finally drugs were delivered inside a single cell through a very small area of the cell membrane. In 2012, Chen et al. demonstrated another localized single cell membrane electroporation usimg ITO microelectrode based transparent chip [27]. Figure 14 shows microfluidic localized single cell membrane electroporation device. They deposited ITO films on a covered glass substrate and patterend it by standard lithographic process to form as ITO lines. After that, a thin SiO2 layer was deposited as a passivation layer by plasma enhanced chemical vapor deposition (PECVD) technique. The final ITO lines were cut by the focused ion beam (FIB) technique. The gap between two electrodes were 1 μm and width of each electrode was 2 μm. When single cell was strongly attached in be tween two electrodes gap, the electric field was intensed in only a 1 μm gap area on single cell membrane. As a result, they demonstrated localized single cell membrane electroporation with microfluidic device. Figure 14a shows localized electroporation process between two micro-electrodes and Figure 14b shows multiple number of electrodes for LSCMEP process. Figure 14 c and d shows the optical microscope image of patterened ITO microelectrodes and scanning electron microscope (SEM) image of ITO microelectrodse with micro-channel. According to their results, they achived 0.93 μm electroporation region with 60% cell viability for 8Vpp 20 ms pulse application. To reduce the gap between two electrodes, a high transfection rate can beachived by this technique. This device not only control the recovery of cell membranes (reversible electroporation) without cell damage but also it provides clear optical view by using an inverted microscope (ITO based transparent chip). Recently, another LSCMEP based device was proposed by Jokilaakso et al. [77] for single cell lysis. They reported a silicon nanowire and nanoribbon based biological field effect transistor for single cell positioning and lysis mechanism. Figure 15a shows the cross sectional view and electric connection with PDMS above the device and Figure 15b shows an array of the transistors with both nanowires and nanoribons. To position the single cell on this device, they used programmable magnetic field for magnetic manipulation of 7.9 μm COOH modified COMPEL magnetic microsphere. After positioning the single cell (HT-29) on top of the transistor, cells were adhered for 30 min prior to electroporation experiment. The applied electric field was 600–900 mVpp (peak to peak) at 10 MHz for 2 ms pulse. This electric field was connected with a shorted source and drain in one terminal and another terminal connected on the gate of the device. The electric field intensity was fringing in nature, which affected the cell membrane integrity leading to cell lysis. This device can perform single cell lysis which is potentially applicable to medical diagnostics and biological cell studies.In summary, this article describes the details about bulk electroporation (BEP), single cell electroporation (SCEP), and localized single cell membrane electroporation (LSCMEP) by using micro/nanofluidic devices with their advantages and disadvantages. All of these processes can deliver drugs, DNA, RNA, oligonucleotides, proteins, etc. However, to analyze cell to cell behavior with their organelles and intracellular biochemical effect, single cell analysis must be executed. Micro/nanofluidic devices are the potential candidates to analyze single cells, because of their dimension reduction to the dimension of single cell level. These devices provide easy performance such as cell handling, lower power consumption, low toxicity, small sample volume, lower contamination rate, high cell viability, and high transfection rate when compared to conventional electroporation. To reduce the electrode area and gap between two electrodes by using micro/nanofluidic devices,selective and localized drug delivery is possible. This new approach is called localized single cell membrane electroporation (LSCMEP). However, until now this technique is in the development stage. In the future, the LSCMEP process can provide selective and specific single cell manipulation from millions of populations of cells together. Micro/nanofluidic devices can approach this level in the near future, which will be potentially beneficial for medical diagnostics, proteomics analysis and biological studies.Part2：Nerve and muscle cells2.1 INTRODUCTIONIn this chapter we consider the structure of nerve and muscle tissue and in particular their membranes(动植物体内的隔膜、薄膜), which are excitable. A qualitative description of the activation process follows. Many new terms and concepts are mentioned only briefly in this chapter but in more detail in the next two chapters, where the same material is dealt with from a quantitative rather than a qualitative point of view.The first documented reference to the nervous system is found in ancient Egyptian records. The Edwin Smith Surgical Papyrus, a copy (dated 1700 B.C.) of a manuscript composed about 3500 B.C., contains the first use of the word "brain", along with a description of the coverings of the brain which was likened to the film （薄层、薄膜）and corrugations（起皱、皱纹）that are seen on the surface of molten copper（熔融铜）as it cooled (Elsberg, 1931; Kandel and Schwartz, 1985).The basic unit of living tissue is the cell. Cells are specialized in their anatomy and physiology to perform different tasks. All cells exhibit a voltage difference across the cell membrane. Nerve cells and muscle cells are excitable. Their cell membrane can produce electrochemical impulses and conduct them along the membrane. In muscle cells, this electric phenomenon is also associated with the contraction of the cell. In other cells, such as gland cells and ciliated cells, it is believed that the membrane voltage is important to the execution of cell function.The basic unit of living tissue is the cell.

Their cell membrane can produce electrochemical impulses and conduct them along the membrane. In muscle cells, this electric phenomenon is also associated with the contraction of the cell. In other cells, such as gland cells and ciliated cells, it is believed that the membrane voltage is important to the execution of cell function.The origin of the membrane voltage is the same in nerve cells as in muscle cells. In both cell types, the membrane generates an impulse as a consequence of excitation. This impulse propagates in both cell types in the same manner. What follows is a short introduction to the anatomy and physiology of nerve cells. The reader can find more detailed information about these questions in other sources such as Berne and Levy (1988), Ganong (1991), Guyton (1992), Patton et al. (1989) and Ruch and Patton (1982).2.2 NERVE CELL2.2.1 The Main Parts of the Nerve CellThe nerve cell may be divided on the basis of its structure and function into three main parts:(1) the cell body, also called the soma;(2) numerous short processes of the soma, called the dendrites; and,(3) the single long nerve fiber, the axon.Fig. 2.1. The major components of a neuron.The body of a nerve cell (see also (Schad and Ford, 1973)) is similar to that of all other cells. The cell body generally includes the nucleus, mitochondria, endoplasmic reticulum, ribosomes, and other organelles. Since these are not unique to the nerve cell, they are not discussed further here. Nerve cells are about 70 - 80% water; the drymaterial is about 80% protein and 20% lipid. The cell volume varies between 600 and 70,000.The short processes of the cell body, the dendrites, receive impulses from other cells and transfer them to the cell body (afferent signals). The effect of these impulses may be excitatory or inhibitory. A cortical neuron (shown in Figure 2.2) may receive impulses from tens or even hundreds of thousands of neurons (Nunez, 1981).The long nerve fiber, the axon, transfers the signal from the cell body to another nerve or to a muscle cell. Mammalian axons are usually about 1 - 20 in diameter. Some axons in larger animals may be several meters in length. The axon may be covered with an insulating layer called the myelin sheath, which is formed by Schwann cells (named for the German physiologist Theodor Schwann, 1810-1882, who first observed the myelin sheath in 1838). The myelin sheath is not continuous but divided into sections, separated at regular intervals by the nodes of Ranvier (named for the French anatomist Louis Antoine Ranvier, 1834-1922, who observed them in 1878).2.2.2 The Cell MembraneThe cell is enclosed by a cell membrane whose thickness is about 7.5 - 10.0 nm. Its structure and composition resemble a soap-bubble film (Thompson, 1985), since one of its major constituents, fatty acids, has that appearance. The fatty acids that constitute most of the cell membrane are called phosphoglycerides. A phosphoglyceride consists of phosphoric acid and fatty acids called glycerides (see Figure 2.3). The head of this molecule, the phosphoglyceride, is hydrophilic (attracted to water). The fatty acids have tails consisting of hydrocarbon chains which are hydrophobic (repelled by water).Fig. 2.3. A sketch illustrating how the phosphoglyceride (or phospholipid) molecules behave in water. See text for discussion.翻译一：细胞工程在2007年。

数据共享是网络的重要应用之一。网络可以共享交易数据，搜索和查询数据，信息，公告板，日历，团队和个人信息数据，备份等。在交易的时候，连接一个公司的电脑的中央数据库包括现有库存信息和出售的数据信息。如果数据被储存在一个中央数据库中，搜查结果便可从中获取。电子邮件的发送已经成为同事之间最常用的信息共享的方式之一。
自从信号在空中传输后，广播，光以及红外线作为传播媒体已经不需要电缆。
传输能力，即一个传播媒体一次性传输的数据量，在不同的媒体中，材料不同，安装时付出的劳动不同，传输的能力有很大的区别。传播媒体有时候被合并，代替远地域之间的高速传播媒体，速度虽慢，但是成本低，在一幢大楼中进行信息传播。
连接设备包括网络连接卡NICS，或者在计算机和网络间进行传输和信号传递的局域网LAN卡。其他常用的设备连接不同的网络，特别是当一个网络使用不用的传输媒体的时候。使用一个对很多用户都开放的系统很重要，比如windows/NT,Office2000，Novell，UNIX.

Circuit analysis with MATLAB文献翻译
文献翻译英文原文：Circuit analysis with MATLABThe electrical appliances is becoming more and more important in today’s world where computer technology, internet technology and communication technology are developing rapidly and people’s life has been greatly imp roved.Circuit analysis is a necessary course and basic knowledge for electronic special student. It is the foundation of circuit maintenance and circuit application. As one of the most important subjects for an under-graduated student who’s mayor in elect ronic information engineering, circuit analysis state for the professional capability. With the development of the circuit analysis field, circuits get more complicated and simulation technology using computer grown up. Dynamic circuit analysis is the most difficult, which takes time and a huge mount of manual work especially when circuit is complicated. So we uses the Matlab/Simulink simulation tools and the power system block model library to make analysis on several simple circuit such as the alternating urgent steady-state circuit、direct current steady-state circuit and first-order dynamic circuit. The circuits are programmed by Matlab language and simulate it by Simulink tools. Although simulation by computer software can not replace the traditional way, it helps people to understand circuit analysis directly and effectively. By these tools，people can demonstrate the circuit performances and reduce complicated calculation. It makes us save a lot of work. During this process，we know how Matlab/Simulink work and show the advantage of Matlab/Simulink tools on circuit analysis，it turns out to be simple，convenience，efficient and flexible.MATLAB is a high-performance language for technical computing. It integrates computation, visualization, and programming in an easy-to-use environment where problems and solutions are expressed in familiar mathematical notation. Typical uses include:1．Math and computation2．Algorithm development3．Modeling, simulation, and prototyping4．Data analysis, exploration, and visualization5．Scientific and engineering graphics6．Application development, including graphical user interface building MATLAB is an interactive system whose basic data element is an array that doesnot require dimensioning. That allows you to solve many technical computing problems, especially those with matrix and vector formations in a fraction of the time, which would take a lot of time to write a program in a scalar non-interactive language such as C or FORTRAN.The name MATLAB stands for matrix laboratory. MATLAB was originally written to provide easy access to matrix software developed by the LINPACK and EISPACK projects. Today, MATLAB engines incorporate the LAPACK and BLAS libraries, embedding the state of the art in software for matrix computation.MATLAB has evolved over a period of years with input many users. In university environments, it is the standard instructional tool for introductory and advanced courses in mathematics, engineering, and science. In industry, MATLAB is the tool of choice for high-productivity research, development, and analysis.MATLAB features a family of add-on application-specific solutions called toolboxes. Very important to most users of MATLAB, toolboxes allow you to learn and apply specialized technology. Toolboxes are comprehensive collections of MATLAB functions (M-files) that extend the MATLAB environment to solve particular classes of problem. Areas in which toolboxes are available include signal processing, control systems, neural networks, fuzzy logic, wavelets, simulation, and many others.The MATLAB system consists of five main parts:Development environment. This is the set of tools and facilities that help you use MATLAB functions and files. Many of these tools are graphical user interfaces. It includes the MATLAB desktop and Command Windows, a command history, an editor and debugger, and browsers for viewing help, the workspaces, files, and the search path.The MATLAB Mathematical Function Library. This is a vast collection of computational algorithms ranging from elementary functions like sum, sine, cosine, and complex arithmetic, to more sophisticated functions like matrix eigenvalue, Bessel functions, and fast Fourier transforms.The MATLAB Language. This is a high-level matrix/array language with control flow statements, functions, data structures, input/output, and object-oriented programming features. It allows both “programming in the small” rapidly create quick and dirty throw-away programs, and “programming in the large” to create complete large and complex application programs.Graphics. MATLAB has extensive facilities for displaying vectors and matrices as graphs, as well as annotating and printing these graphs. It includes high-level functions for two-dimensional and three-dimensional data visualization, image processing, animation, and presentation graphics. It also includes low-level functions that allow you to fully customize the appearance of graphics as well as build complete graphical user interfaces on your MATLAB applications.The MATLAB Application Program Interface(API). This is a library that allows you to write C and FORTRAN programs that interact with MATLAB. It include facilities for calling routines from MATLAB(dynamic linking), calling MATLAB as a computational engine, and for reading and writing MAT-files.In the circuit analysis the RLC two steps electric circuits analysis process is quite complex, and must make the response curve analysis system the performance index extremely to be also difficult. Moreover to the second-order differential equation solution also is quite troublesome, therefore causes the majority the schoolmate which studies this class when studies two steps electric circuits understands quite difficultly. But MATLAB is visible face science and engineering calculation large-scale outstanding science and technology application software, its sentence succinct, the function formidable, simple is practical, in the circuit analysis, the computation has the widespread application. MATLAB provides massive and the rich built-in function, the highly effective succinct sentence, can meet each kind of needs which the electric circuit calculates, the MATLAB language permission plural number direct participation operation, has satisfied the alternating-current circuit analysis, the computation demand. The MATLAB language may directly draw up the voltage, the electric current measures the chart, but measures the chart analyzes the alternating-current circuit essential important tool, is other computation language strength can not.参考译文：MATLAB与电路分析在当今世界，计算机技术，网络技术和通信技术正在迅猛的发展，人民的生活水平逐步提高，电子产品变得越来越重要。

使用了一个长期的随机部署的传感器节点本文针对目标检测的问题监测的区域。
局部区域覆盖被认为是这样的，即该传感器节点的空间密度通常是小的，因为这可能是这种情况在大地区的许多现实的监控方案。
在这样庞大而长远的部署，主要设计目标之一是最大化该系统的运行寿命，通过周期性地打开和关闭传感和通信部分，同时确保目标最终将被检测到，并且相应的通知将一个给定的时间间隔内发送。
虽然最近几年内目标检测的问题已经被广泛研究（例如，见[1-4] ），一个完整的性能建模框架仍然在现实背景下缺失目标检测应用的高能效无线传感器网络。
在本文中我们进一步扩展提出的初步结果在[5] ，推导基于一组相关度量大的性能分析框架。
本文汇集了以下主要贡献：它提出了一个分析框架来描述的义务，有环（在传感和性能通信层）无线传感器网络中错过了目标检。
