一、板式换热机组电控设计标准《低压成套开关设备》-GB7251-2005《低压配电设计规范》-GB50054-1995《自动化仪表工程施工及验收规范》 -GB 50093《电气装置安装工程接地装置施工及验收规范》-GB 50169电控柜应具有的保护功能1、短路保护2、接地保护3、过载保护4、缺项保护5、报警功能6、欠压保护众所周知,在控制系统中经常提到两个专业术语,即“模拟量”和“开关量”。

不论输如还是输出,一个参数要么是模拟量,要么是开关量或数字量。

模拟量在时间上或数值上都是连续的物理量称为模拟量(如温度从0-100度、压力从0-1.6Mpa、或调节阀的开度0-100%等)。

把表示模拟量的信号叫模拟信号。

把工作在模拟信号下的电子电路叫模拟电路。

数字量在时间上和数量上都是离散的物理量称为数字量(常说的物理量的两种状态,即开关的通和断或继电器的闭合和打开灯)。

把表示数字量的信号叫数字信号。

把工作在数字信号下的电子电路叫数字电路。

控制器:按照预定顺序改变主电路或控制电路的接线和改变电路中电阻值来控制电动机的启动、调速、制动和反向的主令装置。

可编程逻辑控制器(Programmable Logic Controller,PLC),它采用一类可编程的存储器,用于其内部存储程序,执行逻辑运算、顺序控制、定时、计数与算术操作等面向用户的指令,并通过数字或模拟式输入/输出控制各种类型的机械或生产过程。

中央处理单元(CPU):是可编程逻辑控制器的控制中枢。

它按照可编程逻辑控制器系统程序赋予的功能接收并存储从编程器键入的用户程序和数据;检查电源、存储器、I/O以及警戒定时器的状态,并能诊断用户程序中的语法错误。

当可编程逻辑控制器投入运行时,首先它以扫描的方式接收现场各输入装置的状态和数据,并分别存入I/O映象区,然后从用户程序存储器中逐条读取用户程序,经过命令解释后按指令的规定执行逻辑或算数运算的结果送入I/O映象区或数据寄存器内。

Theycalled this new feature an "Add-On Instruction" (AOI). This AOI featureallows third party vendors, panel builders, and system integrators to createladder logic code that can be protected for safety or security reasons andcan be locked to ensure that the code remains unchanged.ProSoft Technology®’s inRAx® Modbus TCP/IP Ethernet CommunicationModule for ControlLogix®, the MVI56(E)-MNET, is provided with an Add-On Instruction to allow easy integration of the module into new or existingRSLogix 5000 Version 16 and newer projects.ProSoft Technology® has enhanced the MVI56(E)-MNET module’s Add-On Instruction in a way that will significantly simplify installation.Now users can integrate the module into a new or existing project byimporting a single ladder logic import file, as opposed to importing multipleUser Defined Data Types and ladder logic rungs, one-by-one.The entire ladder logic required by the MVI56(E)-MNET is encapsulated inone, single Add-On Instruction. And, when the ladder logic .L5X file isimported, it automatically creates all the required User-Defined Data Types,Controller Tags, and the Add-On Instruction logic, all while adding thepreconfigured AOI instruction to the ladder rung.This new way of importing an AOI as a completed ladder rung enables quicker and easier integration of theMVI56(E)-MNET with fewer chances for human typographical errors and ladder coding or setup errors.Instructions1 Open the F ILE menu, and then choose N EW…2 Select your ControlLogix controller model.3 Select R EVISION 16.4 Enter a name for your controller, such as "My_Controller".5 Select your ControlLogix chassis type.6 Select S LOT 0for the controller.7 Add the MVI56(E)-MNET module to the project.In the C ONTROLLER O RGANIZATION window, select I/O C ONFIGURATION and click the right mouse button to open a shortcut menu. On the shortcut menu, choose N EW M ODULE...This action opens the S ELECT M ODULE dialog box.8 Select the 1756-M ODULE (G ENERIC 1756M ODULE)from the list and click OK.This action opens the N EW M ODULEdialog box.9 In the N EW M ODULE dialog box, enter the following values.Parameter ValueN AME Enter a module identification string. Example: Modbus TCP/IPEthernet.D ESCRIPTION Enter a description for the module.

Select the R EQUESTED P ACKET I NTERVA l value for scanning the I/O on the module.This value represents the minimum frequency at which the module will handle scheduled events. This value should not be set to less than 1 millisecond. The default value is 5 milliseconds. Values between 1 and 10 milliseconds should work with most applications.12 Save the module.Click OK to close the dialog box. Notice that the module now appears in the C ONTROLLER O RGANIZATION window.13 In the C ONTROLLER O RGANIZATION window, expand the T ASKS folder and subfolder until you reach theM AIN P ROGRAM folder.14 In the M AIN P ROGRAM folder, double-click to open the M AIN R OUTINE ladder.15 Select an empty rung in the new routine, and then click the right mouse button to open a shortcut menu. On theshortcut menu, choose I MPORT R UNG…16 Navigate to the location on your PC where you saved the Add-On Instruction (for example, "My Documents" or"Desktop"). Select the MVI56(E)M ODBUS TCP/IP E THERNET_A DD O N_R UNG_<V ERSION #>.L5X fileThis action opens the I MPORT C ONFIGURATION dialog box, showing the controller tags that will be created.17 If you are using the module in a different slot (or remote rack), select the correct connection input and outputvariables that define the path to the module. If your module is located in Slot 1 of the local rack, this step is not required.18 Click OK to confirm the import. RSLogix will indicate that the import is in progress:When the import is completed, the new rung with the Add-On Instruction will be visible as shown in the following illustration.The procedure has also imported new User Defined Data Types, data objects and the Add-On instruction for your project.19 Save the application and then download the sample ladder logic into the processor.BenefitsThis process for importing the MVI56(E)-MNET Add-On Instruction into the RSLogix ladder logic file has replaced the practice of importing User Defined Data Types and multiple rungs of ladder in multiple ladder files.This enhancement allows you to easily integrate the module into a new or existing RSLogix project without manually copying over each file. Doing so practically eliminates human typographical errors. Additionally, errors that do occur are significantly easier to correct.。

安徽淮南新元古代原始三叶虫(?)化石发现及其地质意义3宋珍炎安徽理工大学资源与环境工程系,安徽淮南2320013安徽省教育厅自然科学基金资助(N o:2001kj206)关键词 安徽淮南 新元古代 原始三叶虫(?)一、引 言 三叶虫出现于距今5.43亿年前的寒武纪,现已绝灭.出自于安徽淮南新元古代地层中的原始三叶虫(?)化石是迄今为止世界上最早的三叶虫化石,其时限为距今7亿年前.本文阐述了该化石的特征,并探讨了该化石及其产地在地球早期生物演化中的作用. 三叶虫是节肢动物中化石最多的一个纲,已论述约1500个属,一万多个种.三叶虫躯体背面覆以坚实的背甲,背甲由前向后横分为三部分,即头甲、胸甲和尾甲.背甲被两条纵沟即背沟纵向分为三个部分,即中间一个轴部和两边的两个肋部.因背甲的三分性非常明显,故名三叶虫.三叶虫极盛于距今5.43亿年前的寒武纪,从奥陶纪开始种类逐渐减少,直至距今2.50亿年前二叠纪全部绝灭.三叶虫成虫一般长3~10cm,最小不及1cm,最长可达70cm,全为海生[1].最早的三叶虫化石发现于早寒武世地层里,并与其他众多门类的无脊椎动物构成了地球早期的生物大爆发.按照生物进化论的观点,三叶虫决非突然出现.在寒武纪之前,应该有它的祖先,只因该期受其硬体不发育、种数少、保存和出露条件限制,至今未发现任何化石记录.国内学者陈孟莪等也持这一观点[2,3].安徽淮南,地处华北地台南缘台褶带东端,其稳定的盖层中发育了温暖浅海环境下连续沉积、厚达千米、未经变质的新元古界地层[4],其时间跨度为早于寒武纪、长达3亿年之久[5],独特的古地理环境和地质条件为研究地球早期生物演化提供了理想的场所.最近笔者在淮南八公山发现的原始三叶虫(?)化石无疑证实了上述推论.二、化石特征 该化石产于灰黄色中厚层含粉砂泥质粉晶灰岩中,虫体周围至岩层顶面间的岩石构造被扰动,层面具冲刷现象,上为纹层灰岩覆盖,化石生物特征明显.虫体为长椭圆形,体长16mm,宽4mm.头甲大,为半长圆形,具头刺,头鞍棒状平直,无鞍沟,胸甲分节7对,尾小.化石背甲纵、横三分明显,属大头小尾型,完全不同于寒武纪及其后期发现的三叶虫化石,故名为原始三叶虫(?)(见图1),标本现藏于安徽理工大学古生物地质实验室中.图1 原始三叶虫(?)三、地质时代 化石产出地层层位为安徽淮南八公山地区上前寒武系九里桥组,K-Ar法同位素年龄资料为距今7.38亿年前左右[6],S r・C 同位素界定其年龄大于7亿年[7],故化石年龄应为距今7亿年前.其地质年代依全国地层委员会资料[8],应属新元古代南华纪.四、地质意义1.世界上最早的三叶虫 目前,三叶虫化石最早出现在距今5.43亿年前的寒武纪,世界上公认的大冰期后的以似水母、似蠕虫为代表的伊迪卡拉动(上接第182页)12 CCRM A.Im pact of string stiffness on virtual bowed strings[E B/O L].http://ccrma-w w w.stan /~jos/stiffbowed/stiffbowed.pd f, 200213 Nakai M.On different m otions of a bowed string.Proceedings o f Asia-Pacific Vibration Conference’95,V ol.II,Japan,1995:459-46614 S.钱得拉赛卡.莎士比亚、牛顿和贝多芬:不同的创造模式.长沙:湖南科学技术出版社,200215 H.伊夫斯.数学史上的里程碑.北京:北京科学技术出版社, 199016 G.萨顿.科学的历史研究.北京:科学出版社,199017 B.格林.宇宙的琴弦.湖南:湖南科学技术出版社.2002 Approaching the World of Musical String—On the 3000years of the research on string and some rela2 tive considerationsY ang JianGraduate Student,Music College,Nanjing Art Institute,Nanjing,China 210013K ey w ords string,plucked-string m odel,Helmholtz m otion,art,science・381・自然杂志 26卷3期研究通信物群年龄为距今6.80~5.70亿年前,我国在7.00亿年前发现的可靠动物化石仅为蠕虫类[6].在安徽淮南,距今7亿年前新元古代地层中发现的原始三叶虫(?)当属世界上最早的三叶虫.2.淮南生物群又添新物种 产于安徽淮南地区的新元古代地层中,闻名于世的淮南生物群主要由宏观藻类组合和蠕形动物组合而成[5].蠕形动物化石表现为压扁的炭化膜,个体细长且小.笔者曾于2002年介绍了淮南新元古代地层中发现的掘迹化石[9],据其掘迹规模的大小绝非蠕虫所为,该期应存在有别于蠕形动物的另一类动物.原始三叶虫(?)化石的发现为淮南生物群增添了新的物种.3.演化趋势与生态 依据原始三叶虫(?)的特征,表明早期三叶虫形态为长卵形,大头小尾,胸节多,头鞍平直,具锐利头甲,并由此向其他方向发展. 从原始三叶虫(?)对周围物质扰动的产出状态及其所具的锐利头甲,表明早期三叶虫是在浅海海底栖息,在沉积物中摄取有机质生活.4.生物矿化作用的出现 三叶虫实体化石的发现,标志着生物矿化作用在距今7亿年前已经出现,其骨骼化已经开始.5.世界上最早后生动物化石的圣地 安徽淮南八公山新元古代地层中原始三叶虫(?)的发现,以及掘迹化石的发现,给以世界古生物圣地为主题的八公山国家地质公园增添了新的色彩.这块土地的神奇之处,则在于在寒武纪之前,长达3亿年的时间内该区一直为温暖的浅海环境,生活在浅海环境下的宏观藻类改善了海水的含氧量,提供了大量的有机物质.几亿年的温暖浅海环境为多细胞动物的生存、繁殖、进化提供了充足的时间和物质保证.地台盖层稳定的沉降,又为生物提供了合适的埋藏和保存条件.神奇、秀丽以及蕴含丰富人文景观的淮南八公山必将吸引更多的国内外学者、地学爱好者前来观光考察,探究地球早期多细胞动物的起源、形态、生态及其演化规律.在这块神奇的土地上也必将有更多的科学发现.(2004年2月10日收到)1 张永辂等.古生物学.北京:地质出版社,1988:1762 陈孟莪.前寒武纪研究进展,1999;22(3):36-463 朱士兴.前寒武纪研究进展,1999;22(2):59-644 郑文武.合肥工业大学学报,1995;17(1):152-1595 牛绍武等.地层学杂志,2002;26(1):1-76 陈孟莪等.地质科学,1986;(3):221-2317 杨杰东等.地层学杂志,2001;25(1):44-478 全国地层委员会.中国地层指南及中国地层指南说明书.北京:地质出版社,2001:55-569 宋珍炎.淮南职业技术学院学报,2002;3(2):51-54The Discovery of N eoproterozoic E ra Prototrilobite(?)Fossil in H uainan Anhui and Its G eological Sig 2nificanceS ong Zhen-yanDepartment o f Resources and Environmental Engineering ,Anhui Univer sity o f Science and Technology ,Huainan Anhui 232001K ey w ords Huainan Anhui ,neoproteroz oic era ,prototrilobite ?酪蛋白平板法检测蚯蚓纤溶酶活性武金霞 赵晓瑜河北大学生命科学学院,河北071002关键词 蚯蚓纤溶酶 酪蛋白平板 纤维蛋白平板 根据蚯蚓纤溶酶能水解酪蛋白(C asein )的性质,建立了酪蛋白平板检测蚯蚓纤溶酶活性的方法.与纤维蛋白平板法相比较,酪蛋白平板法具有铺板简便、灵敏度高等优点,能检测的最小样品量为0.23μg ,而纤维蛋白平板法能检测的最小样品量为0.53μg. 1983年,日本宫崎医科大学美源恒教授首次证明蚯蚓提取物(earth w orm fibrin olytic enzyme ,简称EFE )具有溶解纤维蛋白的作用,EFE 是蚯蚓体内提取的能溶解血纤维蛋白的蛋白水解酶[1],与其他用于溶栓的药物相比,有不易诱发出血,可以口服,来源广泛等优点[2],是一种极具开发潜力的溶栓物质.因此,许多学者研究了EFE 的分离纯化、药理作用、基因克隆与表达等[2-4].EFE 活性检测是所有研究的基础,目前有酪蛋白底物法、气泡上升法、T A ME 法、纤维蛋白平板法等,其中纤维蛋白平板法较常用,因为它直接测定纤溶酶水解血栓主要成分纤维蛋白的能力,但该方法具有铺板过程烦琐、纤维蛋白原易沉淀、凝血酶易失活等缺点.建立一种简便检测纤溶酶活性的方法十分必要.一、材料与方法1.材 料 蚯蚓(E isenia Foetida )匀浆液(自制),考马斯亮蓝R -250为S igma 产品,纤维蛋白原为中国药品检定所产品,酪蛋白及其他试剂为国产分析纯.2.方 法 (1)纤维蛋白平板法测EFE 活性将平板(7cm ×9cm )放在水平仪上调至水平,用1倍pH 7.2P BS 溶液配制1%的琼脂糖,取5m L 于65℃恒温,另取等体积缓冲液5m L ,在25℃恒温箱中保温,加入1/4支纤维蛋白原和10U 凝血酶,终浓度为3mg/m L ,两种溶液迅速混匀,趁热倒入平板中,将气泡赶至边缘,室温下凝固.用直径3m m 的打孔器打孔,将不同浓度的样品点在・481・Ziran Zazhi V ol.26N o.3研究通信。

Data sheetActuators for modulating control AME 55, AME 56DescriptionThe actuators AME 55 and AME 56 are used with VL 2, VL 3 or VFS 2 valves from DN 65 up to DN 100 diameter or VF 2, VF 3 valves from DN 65 up to DN 150 diameter.The actuator automatically adapts itsstroke to valve end positions which reduces commissioning time.Main data:• The advanced design incorporates load related ‘switch-off’to ensure that actuators and valves are not exposed to overload.• The advanced design incorporates adiagnostic LED, operational data capture and self stroking feature. •Manual override.OrderingType Power supply Code No.AME 5524 V~082H3022AME 5624 V~082H3025TypeCode No.Active return signal kit for AME 55, AME 56082H3070Stem heater (VF, VL valves DN 65 - 100)065Z7020Stem heater (VF valves DN 125, 150 and VFS valves DN 65 - 100)065Z7022Technical dataAccessoriesType AME 55AME 56Power supply 24 V~; +10 to –15%Power consumption 9 VA 19.5 VAFrequency 50 HzControl input Y 0 to 10 V (2 to 10 V) Ri = 24 kΩ0 to 20 mA (4 to 20 mA) Ri = 500 ΩOutput signal X 0 to 10 V (2 to 10 V)Close of force 2000 N 1500 N Max. stroke 40 mm Speed8 s/mm 4 s/mmMax. medium temperature 200 °C Ambient temperature 0 to 55 °C Storage and transport temp. –40 to +70 °C Protection code IP 54Weight3.8 kg- marking in accordance with standardsEMC Directive 89/336/EEC, 92/31/EEC, 93/68/EEC, EN 50081-1and EN 50082-1InstallationMechanicalThe actuator should be mounted with the valve stem in either horizontal position or pointing upwards. Use a 4 mm Allen key (not supplied) to fit the actuator to the valve body.Allow for necessary clearance for maintenance purposes.The valve has position indication ringswhich should be pushed together before commissioning; after stroking they indicate the ends of the stroke.ElectricalElectrical connections can be accessed by removing the cover. Two M16 x 1.5 cable entries are provided. Both entries are provided with a rubber grommet for use with flexible cable.Note that in order to maintain the enclosure IP rating, appropriate cable glands must be used.Disposal The actuator must be dismantled and theelements sorted into various material groupsbefore disposal.DIP switch settingThe actuator has a function selection DIP switch under the removable cover. In particular, if SW6 is set to ON, the actuator will perform as 3-point actuator.The switch provides the following functions:• SW1: U/I - Input signal type selector:If set to OFF position, voltage input is selected. If set to ON position, current input is selected.• SW2: 0/2 - Input signal range selector:If set to OFF position, the input signal is in the range from 2 V to 10 V (voltage input)or from 4 mA to 20 mA (current input). If set to ON position, the input signal is in the range from 0 V to 10 V (voltage input) or from 0 mA to 20 mA (current input).• SW3: D/I - Direct or inverse acting selector:If set to OFF position, the actuator is direct acting (stem lowers as voltage increases). If actuator is set to ON position the actuator is inverse acting (stem raises as voltage increases).• SW4: 0..5V/5...10V - Normal or sequential mode selector:If set to OFF position, the actuator is workingin range 0(2)..10V or 0(4)..20mA. If set to ON position, the actuator is working in sequential range; 0(2)..5 (6)V or (0(4)..10 (12)mA) or(5(6)..10V) or (10(12)..20mA).• SW5: —/Seq - Input signal range in sequential mode:If set to OFF position, the actuator is working in sequential range 0(2)..5 (6)V or 0(4)..10 (12)mA. If set to ON position, the actuator is working in sequential range; 5(6)..10V or 10(12)..20mA.• SW6: Prop./3-pnt - Modulating or 3-point mode selector:If set to OFF position, the actuator is working normally according to control signal. If set to ON position, the actuator is working as 3-point actuator.• SW7: LOG/LIN - Equal percentage or linearflow through valve selector1:If set to OFF position, the flow through valve is equal percentage. If set to ON position, the he flow through valve is linear according to control signal.• SW8: 100% KVS/Reduced KVS- Flow reduction through valve selector1:If set to OFF position, the flow through valve is not reduced. If set to ON position, the he flow through valve reduced by half of increment standard KVSvalues (exsample: valve with KVS16 and SW8 set to ON – maximum flow through the velve is KVS13 (meidle between standard KVS16 and KVS10).1 NOTE: To be used only in combination with valves with equal percentage characteristic• SW9: Reset:Changing this switch position will cause theactuator to go through a self stroking cycle.WiringComplete the mechanical and electricalinstallation and perform the necessary checks and tests:• Isolate control medium. (e.g. self stroking in a steam application without suitable mechanical isolation could cause a hazard).• Apply the power. Note that the actuator will now perform the self stroking function.• Apply the appropriate control signal and check the valve stem direction is correct for the application.• Ensure that the actuator drives the valve over its full stroke, by applying the appropriate control signal. This action will set the valve stroke length.The unit is now fully commissioned.SP24 V~ ............................................Power supply SN 0 V mon Y 0 to 10 V ......................................Input signal (2 to 10 V) 0 to 20 mA (4 to 20 mA)X 0 to 10 V ......................................Output signal(2 to 10 V)Automatic self stroking featureWhen power is first applied,the actuator will automatically adjust to the length of the valve stroke. Subsequently, the self stroking feature can be re-initialised by changing position of SW9.Diagnostic LEDThe red diagnostic LED is located on the pcb under the cover. It provides indication of three operational states: Actuator Healthy (Permanently ON), Self Stroking (Flashes once per second), Error (Flashes 3 times per second - seek technical assistance).Wiring length Recommended square of the wiring 0 - 50 m 0.75 mm 2> 50 m1.5 mm 2CommissioningCommissioning / testing featureThe actuator can be driven to the fully open or closed positions (depending on valve type) byconnecting SN to terminals 1 or 3.24 Vac only.Manual override The manual override is applied by rotating the4 mm Allen key (not supplied) to the requiredposition. Observe the direction of the rotationsymbol.• Disconnect power supply• Adjust valve position using an Allen key• Set valve to closed position• Restore power supplyIf manual override has been used then X and Ysignal are not correct until the actuator reachesits end position. If this is not accepted reset theactuator, or apply accessory active return signalkit.DimensionsActuator - valvecombinations。
