MKS πMFC (mass flow controller) 商品说明书

MFCMODEL PFC-50 AND PFC-60πW W W .M K S I N S T .C O MFlow DIS C O N T I N U E DThe next generation MKS πMFC (mass flow controller) includes technology improvements in functionality and performance to help users in semiconductor and high purity thin-film applications increase tool throughput and reduce overall system costs. Real-time accurate flow control that is insensitive to upstream and downstream pressure disturbances is provided through advanced digital algorithms. Enabling real-time control of process gas flow, accuracy and repeatability is significantly improved over conventional PID based digital MFCs, resulting in better chamber matching.Cost savings to users are seen through several innovative enhancements. T o reduce the number of MFCs in inventory, users can access specific MFC gas calibrations and flow ranges from up to 31 stored gas tables, configuring the πMFC right off the shelf. The integrated pressure sensor and local LED display help to reduce the number of components required in a gas stick. A web based browser interface allows for setup and troubleshooting of MFCs in-situ, thereby reducing the number of “No Problem Found” MFC replacements and the need to break the process gas line.The πMFC represents MKS’ ongoing dedication to helping customers increase productivity while reducing system costs.DescriptionFeatures & BenefitsIncreases Throughput and Perf ormance • Insensitive to upstream and downstream pressure disturbances— Accurate flow control without the need for additional dedicated line pressure regulators• Enables better chamber matching through increased MFC accuracy of any process gas• Increases tool uptime through reduction of “No Problem Found” MFC replacements—Includes embedded diagnostics software that allows users to check MFC functionality without removing the MFC—E-diagnostics through embedded Ethernet interface Reduces Overall Costs• Reduces MFC inventory through multi-gas, multi- range availability• Enables reduction in number of gas stick components needed, such as pressure regulators, filters, and pressure transducers• Minimizes overall footprint of gas delivery moduleEasy to Integrate and Operate• Straightforward configuration and diagnostics through Ethernet interface — U ses standard web browser – no special software required—Includes remote PC application• Easy viewing of line pressure, flow rate, gas type, full scale flow range and Ethernet address with bright LED displayπMFC with Integrated Display —Ethernet e-diagnostics interface and DNET control optionDI SC ONT I NUE DDescription (cont’d)As a technology leader in MFCs, the πMFC represents the latest in cost effective technology and innovation to meet production needs.The performance of the πMFC is quickly apparent where short process steps are required. The ability to provide accurate and real-time control of high molecular weight gas applications differentiates πMFC from other market brands. This results in precise etch rates and controlled deposition for most critical semiconductor processes.T o enable ease of integration into next generation or existing process tools, a variety of mechanicalconfigurations exist, including surface mount and VCR ®. Coupled with its compact size, the πMFC provides an ideal way to migrate from existing analog MFCs where reducing MFC inventory and improving process repeatability are important.T o ensure that customers can easily use the πMFC, the gas selection and full-scale range can be easily selected by the customer to meet specific application requirements (PFC-50). For DeviceNet ™ configurations, this is performed through the DeviceNet protocols or Ethernet interface. For analog I/O users, setup is achieved via Ethernet on or off the tool. Users can configure the πMFC directly through the separate embedded Ethernet port using a standard web browser – no special software is required.The embedded Ethernet port also offers e-diagnostics capability for maintenance and troubleshooting – without interrupting πMFC operation. Password protected, theconfiguration mode provides access to all device functions, live updates, and real-time plotting of pressure and flow conditions.Our award winning manufacturing facility is well versed in producing high quality MFCs to meet the demands of critical ultra-high purity applications. πMFCs aremanufactured in our Class 100 cleanroom, in accordance with ISO 9001 procedures. With short lead times to allow you to meet your ever changing delivery schedules, the πMFC meets your business requirements as well as your technical specifications.Designed with production requirements in mind, the πMFC offers process reliability and device flexibility for all yourgas delivery applications.Figure 1 —πMFC User Interface Screen illustrating DeviceNet ™ parametersFigure 2 —πMFC User Interface Screen demonstrating real-time charting of pressure and flow rate.DI SC ON T I NUE DPerformanceFull Scale Flow Ranges (N 2 equivalent) 5 - 50000 sccm (consult factory for available flow ranges)Maximum Inlet Pressure 150 psig (can not exceed pressure differential requirement across MFC)Normal Operating Pressure Differential 10 to 5000 sccm; 10 to 40 psid (with atmospheric pressure at the MFC outlet) 10000 to 30000 sccm; 15 to 40 psid Proof Pressure 1000 psig Burst Pressure 1500 psig Control Range 2% to 100% of F .S.Typical Accuracy ± 1% of setpoint for > 20 to 100% F .S. ± 0.2% of F .S. for 2 to 20% F .S.Repeatability ± 0.3% of Reading Resolution 0.1% of ReadingTemperature CoefficientsZero < 0.05% of F .S./°C Span < 0.08% of Rdg./°C Inlet Pressure Coefficient < 0.02% of Rdg./psi Typical Controller Settling Time < 1.5 sec typical above 5% F .S.

S7-1200高速计数功能说明介绍

涉及产品1高速计数器S7-1200 CPU提供了最多6个（1214C）高速计数器，其独立于CPU的扫描周期进行计数。

可测量的单相脉冲频率最高为100KHZ,双相或A/B相最高为30KHZ，除用来计数外还可用来进行频率测量，高速计数器可用于连接增量型旋转编码器，用户通过对硬件组态和调用相关指令块来使用此功能。

2高速计数器工作模式高速计数器定义为5种工作模式计数器，外部方向控制。

单相计数器，内部方向控制。

双相增/减计数器，双脉冲输入A/B相正交脉冲输入。

监控PTO输出。

每种咼速计数器有两种工作状态。

外部复位，无启动输入。

内部复位，无启动输入。

所有的计数器无需启动条件设置，在硬件向导中设置完成后下载到CPU中即可启动高速计数器，在A/B相正交模式下可选择1X（1倍）和4X （4倍）模式，高速计数功能所能支持的输入电压为24V DC,目前不支持5V DC的脉冲输入，表1 列出了高速计数器的硬件输入定义和工作模式要注意不是所有计数器可以同时定义为任意工作模式。

高速计数器的输入使用与普通数字量输入相同的地址，当某个输入点已定义为高速计数器的输入点时，就不能再应用于其它功能，但在某个模式下，没有用到的输入点还可以用于其它功能的输入监控PTO的模式只有HSC1和HSC2支持，使用此模式时，不需要外部接线，CPU在内部已作了硬件连接，可直接检测通过PTO功能所发脉冲。

3高速计数器寻址CPU将每个高速计数器的测量值，存储在输入过程映像区内，数据类型为32位双整型有符号数，用户可以在设备组态中修改这些存储地址，在程序中可直接访问这些地址，但由于过程映像区受扫描周期影响，在一个扫描周期内，此数值不会发生变化，但高速计数器中的实际值有可能会在一个周期内变化，用户可通过读取外设地址的方式，读取到当前时刻的实际值。

以ID1000为例，其外设地址为“ID1000 P”表2所示为高速计数器寻址列表表咼速计数器寻址4频率测量S7-1200 CPU除了提供计数功能外，还提供了频率测量功能，有3种不同的频率测量周期：1.0秒，0.1秒和0.01秒，频率测量周期是这样定义的：计算并返回新的频率值的时间间隔。

For morein-depth information, go to our web site:.Powered SubwooferTHANK YOU FOR CHOOSING THIS JBL ® PRODUCTHDI-1200P4X Note: Type of power plug varies by regions.1X1X1One combination LFE and trigger cableE n g l i s hSUBWOOFER REAR-PANEL CONTROLS AND CONNECTION1)Power Mode :When switched to 'Auto' position, the subwoofer will then be in Standby mode. It will automatically turn on when an audio signal is detected and will return to the Standby mode when no audio signal is detected after approximately 10 minutes. Setting this switch to ‘On’ keeps the subwoofer powered until Power Switch is turned 'Off.'2)On/Standby LED:When the Power Switch is in the ‘On’ position, this LED indicates whether the subwoofer is in the On or Standby state.••When the LED glows red, the subwoofer is in the Standby mode.4)Low Pass Crossover:This control determines the highest frequency at which the subwoofer reproduces sounds. The higher you set the Crossover control, the higher in frequency the subwoofer will operate and the more its bass will“overlap” that of the speakers. This adjustment helps achieve a smooth transition of bass frequencies between the subwoofer and the speakers for a variety of different rooms and subwoofer locations.5) Subwoofer Gain:Use this control to adjust the subwoofer’s volume. Turn the knobclockwise to increase the volume; turn the knob counterclock-wise to decrease the volume.6)Input Connectors:Connect these to the outputs of a stereo preamp or connect a surround processor's subwoofer output to either the left or right input. Balanced (XLR) and unbalanced (RCA) connectors are available. The inputs are 0dBV nominal to +12dBV max unbal/+18dBV max bal. The XLR input is pin 2 hot.7)Power Switch:Set this switch in the ‘On’ position to turn the subwoofer on. If you willbe away from home, or will not be using the subwoofer for an extended period, set this switch in the ‘Off’ position to conserve energy.8)Power Cord Connector:After you have made and veriﬁed the subwoofer’s input connection,plug the power cord into an active, unswitched electrical outlet for proper operation of the subwoofer.DO NOT plug the power cord into the accessory outlets found on someaudio components.3)Phase Switch:This switch determines whether the subwoofer transducer’s piston-like action moves in and out in phase with the main speakers. If thesubwoofer were to play out of phase with the main speakers, the sound waves from the main speakers could partially cancel out the sound waves from the subwoofer, reducing bass performance and sonic impact. This phenomenon depends in part on the placement of all the speakers relative to the listening position and to each other in the room.9) 12V Trigger In/Out connectors:When the subwoofer’s Power Mode Switch is set to “Trigger”, the subwoofer will automatically turn on when 5V-12V is present at the 12V Trigger “in-connection”, and will turn off when the voltage at this connection is removed. Whenever the subwoofer in on, a 12V trigger signal is available at it’s 12V Trigger Out connector. It is for use with additional HDI-1200P subwoofers, or another triggerable device.11) EQ Frequency control:Selects the center frequency of the particular problem area. The range is from 32HZ to100Hz.12) EQ Bandwidth control:Sets the range of frequencies over which the equalizer will have an effect. The range is from 0.1 octaves to 0.6 octaves; the higher the number the broader the range of frequencies that will be affected.13) EQ Level control:Allows you to adjust how much boost or cut is applied to the selected frequency by the EQ Frequency Control. This control adjusts from-12dB to a maximum of +3dB.14) EQ On/Off switch:Enables/Disables the parmetric EQ controls (Frequency, Bandwidth, and EQ Level, but not Phase)81，3412111056910) Parametric Equalization (PEQ) controls:This set of equalization controls adjust for the dominant room mode at yourlistening position in your speciﬁc listening room. The parametric equalizer includes variable controls to adjust Frequency, Bandwidth, and EQ Level of one band of frequencies. To use these controls, you must ﬁrst set the EQ switch to “ON”. NOTE: Speciﬁc measurement equipment is required to properly adjust the Equalization controls. Your authorized JBL dealer can make the appropriate measurements, using suitable equipment to ensure optimal results.3When the LED glows green , the subwoofer is turned On.CONNECTING THE SUBWOOFER TO A TRIGGER VOLTAGE SOURCE12VTRIGGEROUTPUTThe subwoofer will automatically turn on if it receives a trigger voltage at its External Trigger Input connector and will enter the Standby mode when the voltage ceases.If your preamp/processor or another audio/video component has a trigger-voltage connection that supplies between 3V and 30V (AC or DC), connect it to subwoofer’s Exteranl Trigger Input connector. If the component’s trigger-voltage connection has a 3.5mm mini jack, you can use the supplied combination LFE/trigger cable to make the connection.NOTE: Do not connect the subwoofer’s External Trigger input connector to a remote control output (IR Out) of your home cinema system or surround receiver. Doing so could lead to malfunction.4PLACING THE SUBWOOFERThe performance of a subwoofer is directly related to its placement in the listening room and its physical position relative to the other speakers in the system.While it is true that in general our ears do not hear directional sounds at the lowfrequencies where subwoofers operate, when installing a subwoofer within the limited conﬁnes of a room, the reﬂections, standing waves and absorptions generated within the room will strongly inﬂuence the performance of any subwoofer system. As a result, the speciﬁc location of the subwoofer in the room does become important to the amount and quality of bass that is produced.For example, placing the subwoofer next to a wall generally will increase the amount of bass in the room; placing it in a corner (1) generally will maximize amount of bass in the room. However, corner placement can also increase the destructive effect of standing waves on bass performance. This effect can vary depending on the listening position – some listening positions may yield very good results while others may have far too much (or too little) bass at certain frequencies.In many rooms, placing the subwoofer along the same plane as the left and rightspeakers (2) can produce the best integration between the sound of the subwoofer and that of the left and right speakers. In some rooms, the best performance could even result from placing the subwoofer behind the listening position (3).We strongly recommend that you experiment with placement before choosing a ﬁnal location for your subwoofer. One way you can determine the best location for the subwoofer is by temporarily placing it in the listening position and playing music with strong bass content. Move around to various locations in the room while the system is playing (putting your ears where the subwoofer would be placed), and listen until you ﬁnd the location where the bass performance is best. Place the subwoofer in that location.MAKING CONNECTIONSCAUTION: Never make or break connections unless all system components are powered off.5CONNECTING TO A STEREO RECEIVER,AMPLIFIER OR PREAMPLIFIERIf you are connecting to a stereo device, connect the subwoofer asshown below. Stereo components rarely have subwoofer outputs. Usethem if they are available; otherwise, be sure to use a Y-connector for theleft output and one for the right output, connecting the subwoofer input toone side of each Y and the input for the left or right or right main speaker ampliﬁerto the other side of the Y for proper main speaker operation. You can make either balanced (XLR) or unbalanced (RCA) connections between the device and the subwoofer.Using this connection method, you must set the Low Pass Crossoverknob to some frequency between 50-150Hz, NOT on the “LFE”setting.6TURNING THE SUBWOOFER ON AND OFFSet the subwoofer’s Power Switch to the ‘On’ position. Now set the subwoofer’s Power Mode to the ‘Auto’ position. The subwoofer willautomatically turn itself on when it receives an audio signal, and it will go into Standby mode after it has received no audio signal for approximately If you will not be using the subwoofer for an extended period – forinstance, if you’re going on vacation – set the Power Switch to the ‘Off’ position.SUBWOOFER ADJUSTMENTS: CROSSOVERThe Crossover control adjusts the subwoofer’s built-in low-pass ﬁlter crossover between 50Hz and 150Hz. The higher you set the Crossover control, the higher in frequency the subwoofer will operate and the more its bass will ‘overlap’ that of the speakers. This adjustment helps achieve a smooth transition of bass frequencies between the subwoofer and the speakers for a variety of different rooms and subwoofer locations.To set the Crossover control, listen for the smoothness of the bass. If the bass seems too strong at certain frequencies, try a lower Crossover control setting. If the bass seems too weak at certain frequencies, try a higher Crossover control setting.SUBWOOFER ADJUSTMENTS: VOLUMEUse the volume control to set the subwoofer’s volume. Turn the knob clockwise to increase the subwoofer’s volume; turn the knobcounterclock-wise to decrease the volume. Once you have balanced the subwoofer’s volume with that of the other speakers in your system, you shouldn’t have to change the volume control setting.Notes on Setting Subwoofer Volume:•Sometimes the ideal subwoofer volume setting for music is too loud for ﬁlms, while the ideal setting for ﬁlms is too quiet for music. When setting the subwoofer volume, listen to both music and ﬁlms with strong bass content and ﬁnd a ‘middle ground’ volume level that works for both.•If your subwoofer always seems too loud or too quiet, you may want to place it in a different location. Placing the subwoofer in a corner will tend to increase its bass output, while placing it away from any walls or corners will tend to lessen its bass output.SUBWOOFER ADJUSTMENTS: PHASEThe Phase switch determines whether the subwoofer driver’s piston-like action moves in and out in phase with the speakers. If the subwoofer were to play out of phase with the speakers, the sound waves from the speakers could partially cancel out the waves from the subwoofer, reducing bass performance and sonic impact. This phenomenon depends in part on the placement of all the speakers relative to each other and the listener(s) in the room.Although in most cases you should leave the Phase switch in the ‘Normal’ position, there is no absolutely correct setting for the Phase switch. When the subwoofer is properly in phase with the speakers, the sound will be clearer and have maximum impact, and percussive sounds like drums, piano and plucked strings will sound more life-like. The best way to set the Phase switch is to listen to music that you know well and to set the switch in the position that gives drums and other percussive sounds maximum impact.USING THE SUPPLIED CARPET SPIKESFour metal spikes are supplied for use when you place the subwoofer on a carpeted surface. Do not use these spikes when placing subwoofer on non-carpeted surfaces.To insert the spikes:1.Gently lay the subwoofer on its side (not its front or back) on a soft,nonabrasive surface.2.Screw each spike into the threaded insert in each foot.

The supply pressure flows to the inlet passes through the path between the nozzle and flapper and acts on the supply diaphragm as nozzle pressure. The force generated by the diaphragm pushes down the valve, and the supply pressure flows to the outlet. The discharged air pressure acts on the exhaust diaphragm, and counteracts against the force generated by the supply diaphragm. The air pressure acts on the nozzle diaphragm at the same time, and counteracts against the compression force of the adjusting spring to adjust the set pressure. When the set pressure increases too much, the nozzle diaphragm is pushed up, and a gap is generated between the flapper and nozzle diaphragm. This happens after the flapper closes. The balance of the supply diaphragm and exhaust diaphragm is lost when the nozzle back pressure flows into the atmosphere. The exhaust valve is open after the valve is closed, and excess pressure on the outlet is released to the air. Due to this pilot mechanism, fine pressure variations are detected and precise pressure adjustment is possible.Component partsNo.DescriptionMaterials① BonnetAluminum die-cast② Nozzle diaphragm assembly Aluminum, Weather resistant NBR③ Seal HNBR ④ SealNBR ⑤ Diaphragm spacerPolyacetal ⑥ Supply diaphragmWeather resistant NBR⑦ Exhaust diaphragm assembly Aluminum, Weather resistant NBR ⑧ Valve assembly Aluminum, stainless steel, HNBR⑨BodyAluminum die-castGrease: lithium greaseValve⑥IN / OUT side４．How to order５．Bracket, gauge and switch assembly (optional)６．Panel mounting7．TroubleshootingNo. Problem Possible causes Countermeasures1 Reduction of the set pressure Fluctuation of flow rate at the downstream sideSet the pressure again.Return the flow rate at the downstream side to the initial rate.Leakage due to deterioration of therubber part.Ozone Use the ozone resistant product (80- series).Temperature Avoid using at high temperature or low temperature.Organic solventetc.Take countermeasures to prevent organic solvent from the ambientatmosphere or fluid.High frequency ON-OFF operation on the downstreamside.Set the pressure again.Pressure in the bonnet is reduced.Release the pressure in the bonnet which is the reference pressure tothe atmosphere.2 The set pressure increases ordecreases as time passes.Aging deterioration of the regulator Set the pressure again.3 Increased leakage from thebonnet breathing hole andexhaust portLeakage due to deterioration ofthe rubber part.Ozone Use the ozone resistant product (80- series).Temperature Avoid using at high temperature or low temperature.Organic solventetc.Take countermeasures to prevent organic solvent from the ambientatmosphere or fluid.Foreign matter caught in the seatInstall a filter or mist separator to clean the air supply.Perform flushing by releasing the downstream side to atmosphere.4 The set pressure changesperiodically.Supply pressure fluctuates.

1nf电容1khz电路容抗

1nf电容1khz电路容抗电容器是一种存储电能的元件，它的容抗可以用来描述电容器对交流电的阻抗特性。

而在1kHz频率下，我们可以探讨1nf电容的容抗问题。

在交流电路中，电容器的容抗与频率有关，可以通过以下公式计算：XC = 1 / (2πfC)其中，XC表示电容器的容抗，f表示频率，C表示电容值。

在1kHz频率下，我们带入C=1nf（即1纳法拉德）进行计算。

首先，将频率转换为弧度制：ω = 2πf = 2π * 1000 = 6283.2 rad/s然后，将C的单位转换为法拉德：C = 1nf = 1 * 10^(-9) F带入公式计算容抗：XC = 1 / (6283.2 * 10^(-9)) Ω ≈ 159.2 Ω因此，在1kHz频率下，1nf电容的容抗约为159.2Ω。

容抗是电容器对交流电的阻抗特性，它与电容器的电容值和频率有关。

当频率较低时，电容器的容抗较大，对电流的阻碍作用也较大；而当频率较高时，电容器的容抗较小，对电流的阻抗作用也较小。

1nf电容器在1kHz频率下的容抗为159.2Ω，这意味着在该频率下，电容器对电流的阻抗为159.2Ω。

换句话说，当1kHz频率的交流电通过1nf电容器时，电容器将对电流产生阻碍作用，阻抗大小为159.2Ω。

需要注意的是，电容器的容抗是一个虚数，它包含了电容器对电流的阻碍作用以及相位差。

在交流电路中，电容器的容抗与电感器的感抗相对，它们共同构成了电路的阻抗。

阻抗的大小和相位差会影响电路中电压和电流的关系，进而影响电路的性能和特性。

在实际电路中，电容器常常被用于滤波、耦合和储能等方面。

通过合理选择电容器的容值和频率，可以实现对交流信号的处理和控制。

对于1nf电容器来说，它在1kHz频率下的容抗为159.2Ω，可以用于滤波、耦合等应用。

总结起来，本文以1nf电容1kHz电路容抗为题，介绍了1nf电容在1kHz频率下的容抗计算方法和结果，并探讨了容抗对交流电的阻抗特性及其在电路中的应用。

1200名小学生考公务员答案雷人淘汰率50%
昨(24)日，“天府小城”公务人员招聘笔试在成都12所小学举行。

1200名小学生参加笔试，竞争“天府小城”市长、警察局长、教育局长、卫生局长、记者等“稀缺岗位”。

满分100分的笔试试卷，最终被统一回收到成都青少年活动中心。

小学生参加“公务员考试”媒体来源：江西卫视节中，“举例说一说为什么节水迫在眉睫？”“你为什么要参加本次‘天府小城’公务员招聘？”这两个问题，小学生们的答案可谓五花八门。

有小学生直言：“现在社会上最Good的工作就是公务员”、“想过一把当官的瘾”，雷倒不少老师。

A一种设想仿真城市设10个行政机构“天府小城”到底是个什么城市？竟然从小学生中选公务人员？初听到这个招聘消息，家长黄明英吓了一大跳，最终她才搞明白，原来“天府小城”是个虚幻的城市，设在占地约256亩的成都市青少年活动中心。

这样一个“小城市”，有会展中心、天府广场、总府路、春熙路等成都市地标街道。

除此之外，还设置了1个市长，2个副市长以及1个市长助理。

在4人的领导管理下，城市还下设10个行政机构：新闻局、文化局、教育局、警察局、卫生局、商务局等。

“每个行政机构，都需要一个局长，若干个办事人员。

”主办此次招聘活动的成都市青少年活动中心负责人杨加军说，昨日是笔试环节，九里堤小学、北站小学、沙河源小学、沙湾路小学等12所学校1200名学生参与考试。

被选中的学生将在明年1月22日至31日，在“天府小城”里体验一天市长、局长或记者的角色。

B 一次考试答案雷人淘汰率高达50%在昨天的笔试卷里，小学生们需要回答涉及科学、地理、体育、物理以及城市管理的内容。

另外，还需要写一篇300多字的“假如我是×××”的竞选文章。

华西都市报记者在沙湾路小学的100份试卷中看到，竞聘者的答案五花八门。

特别是在开放式问答题环节，孩子们充分发挥想象力，给出了不少让人意想不到的答案。

“你为什么要参加本次‘天府小城’公务人员招聘？”有的小学生答：“现在社会上最Good的工作就是公务员，为了体验一下被人们夸赞和羡慕得眼睛发亮的职业。

”有的小学生答：“因为我一直有一个梦想就是，我能有一个自己管理的地方，让生活在这里的人感到骄傲，我觉得公务人员就有这个机会。

”还有的直言不讳说，“我想过一把当官的瘾。

”这样的答案让不少老师雷翻了。

不过，在“举例说一说为什么节水迫在眉睫”这个问题上，有的答案让人啼笑皆非：“因为口渴，没水洗澡会让你很不爽，为了防止以后没水喝。

”有的答案让人深思：“我们常见的是非洲地区，我曾看见一张照片，一个小女孩站的那片土地已经干裂了，小女孩的双唇已不成样，旁边还有一只蛇准备咬她，我多心痛啊！”杨加军介绍，笔试淘汰率高达50%，只有一半应聘学生能进入到面试环节。

C 一次体验工作繁重市长工资一天50元在“天府小城”，不管是市长、局长，还是普通的公职人员，每个人都只能领到50元代金劵充当工资。

不过他们的任务却“相当繁重”。

以市长为例，朝九晚五的工作中，早上先要召开各部门领导会议，布置当天工作任务；随后将在广场参加升旗仪式，面对小镇公民进行即兴演讲；演讲完毕，市长将召开新闻发布会，接受《小城日报》和小城电视台的采访。

做完这些工作，市长还要巡视小城，并对临时产生的危机进行决策处理。

一天的工作结束，还要主持市政工作总结大会，分析问题，总结经验。

“市长的工作很辛苦的，其他职务也不简单。

”杨加军说，如记者就有社会记者、娱乐记者、时政记者之分，他们需要第一时间将小城里的新闻采集回来，并用A4
纸打印，贴在立起来的《小城日报》版面上。

“这需要采访能力、写作能力强的小学生。

”组织这样的“职业体验”活动，杨加军表示，主要是想让小学生们了解社会的构建和职业分工，也让他们提前体验一下找工作的艰辛。

“笔试、面试全部仿照社会上的招聘进行，竞争很激烈。

”杨加军说，为让小学生能胜任小城公务员的工作，中心还邀请了成都电子科技大学、四川大学、西华大学等10所高校的大学生志愿者参与定向指导。
