The RT7251A’s current mode architecture allows the transient response to be optimized. Cycle-by-cycle current limit provides protection against shorted outputs and soft-start eliminates input current surge during start-up. Fault conditions also include output under voltage protection, output over voltage protection, and thermal shutdown. The low current (<5μA) shutdown mode provides output disconnect, enabling easy power management in battery-powered systems. The RT7251A is available in a WDFN-8L 2x2 package.Feature●4V to 17V Input Voltage Range● 1.5A Output Current●Internal N-MOSFETs●Current Mode Control●Fixed Frequency Operation : 340kHz●Output Adjustable from 0.8V to 12V●Up to 95% Efficiency●Internal Compensation●Stable with Low ESR Ceramic Output Capacitors●Cycle-by-Cycle Over Current Protection●Input Under Voltage Lockout●Output Under Voltage Protection●Output Over Voltage Protection●Power Good Indicator●Thermal Shutdown Protection●RoHS Compliant and Halogen FreeKey Performance Summary TableKey features Evaluation board number: PCB005_V1 Default Input Voltage 12VMax Output Current 1.5ADefault Output Voltage 3.3VDefault Marking & Package Type RT7251AZQW (WDFN-8L 2x2)Operation Frequency Steady 340kHz at all load currentsOther Key Features 4V to 17V Input Voltage RangePower Good IndicatorTiny WDFN-8L 2x2 packageProtection Over Current ProtectionHiccup Mode Output Under-Voltage & Over-Voltage ProtectionThermal ShutdownBench Test Setup ConditionsHeaders Description and PlacementPlease carefully inspect the EVB IC and external components, comparing them to thefollowing Bill of Materials, to ensure that all components are installed and undamaged.

EN is automatically pulled high (by R4) to enableoperation. Connect EN low to disable operation.BS Boot strap supply test point Floating supply voltage for the high-side N-MOSFET switchPG Power Good test point Power Good IndicatorV1 External Voltage for PG External voltage terminal for PG pull-up voltage.GND Ground GroundPower-up & Measurement Procedure1. Apply a 12V nominal input power supply (4V < V IN < 17V) to the VIN and GND terminals.2. The EN voltage is pulled to logic high by R4 (100kΩ to VIN) to enable operation. Drive EN high (>2.5V) toenable operation or low (<0.4V) to disable operation.3. Verify the output voltage (approximately 3.3V) between VOUT and GND.4. Connect an external load up to 1.5A to the VOUT and GND terminals and verify the output voltage and current.Output Voltage SettingSet the output voltage with the resistive divider (R1, R2) between VOUT and GND with the midpoint connected to FB. The output is set by the following formula:OUT R1V = 0.8 x (1 + )R2The installed V OUT capacitors (C4, C5) are 22μF, 16V X5R ceramic types. Do not exceed their operating voltage range and consider their voltage coefficient (capacitance vs. bias voltage) and ensure that the capacitance is sufficient to maintain stability and provide sufficient transient response for your application. This can be verified by checking the output transient response as described in the RT7251 IC datasheet.Schematic, Bill of Materials and Board LayoutEVB Schematic DiagramBSC1, C2: 10μF/50V/X5R, 1206, TDK C3216X5R1H106KC4, C5: 22μF/16V/X5R, 1210, Murata GRM32ER61C226KL1: 15μH TAIYO YUDEN NR8040T150M, DCR=50mΩBill of MaterialsReference Qty Part number Description Package Manufacture U1 1 RT7251AZQW DC-DC Converter WDFN-8L 2x2 RichtekC1, C2 2 C3216X5R1H106K160AB 10μF/±10%/50V/X5R1206 TDK Ceramic CapacitorC4, C5 2 GRM32ER61C226KE20# 22μF/±10%/16V/X5R1210 Murata Ceramic CapacitorC7 1GRM32MR71H103KA01# 10nF/±10%/50V/X7R0603 Murata Ceramic CapacitorC3, C6 2 C1608X7R1H104K080AA 0.1μF/±10%/50V/X7R0603 TDK Ceramic CapacitorC8, C9, C10 0 Not Installed 0603L1 1 NR8040T150M15μH/2.7A/±20%,DCR=50mΩ, Inductor8mmx8mmx4mm TAIYOYUDENR1 1 110kΩ/±1%, Resistor 0603 R2 1 36kΩ/±1%, Resistor 0603 R3, R4 1 100kΩ/±1%, Resistor 0603 CP1 1 ShortD3, R6 0 Not InstalledTP 6 TestPinGP 4 GoldenPinEVB LayoutTop View (1st layer)Bottom View (4th Layer)Component Placement Guide—Component Side (1st layer)PCB Layout—Component Side (1st Layer)PCB Layout—Inner Side (2nd layer)PCB Layout—Inner Side (3rd layer)RT7251AZQWEvaluation BoardUG7251AZQW-00 March 2014 11Component Placement Guide—Bottom Side (4th Layer)PCB Layout—Bottom Side (4th Layer)Other Technical InformationF or more information, please find the related datasheet or application notes from the Richtek website。

秩亏自由网
§8-2 秩亏自由网平差2学时在前面介绍的经典平差中,都是以已知的起算数据为基础,将控制网固定在已知数据上。
如水准网必须至少已知网中某一点的高程,平面网至少要已知一点的坐标、一条边的边长和一条边的方位角。
当网中没有必要的起算数据时,我们称其为自由网,本节将介绍网中没有起算数据时的平差方法,即自由网平差。
在经典间接平差中,网中具备必要的起算数据,误差方程为111ˆ⨯⨯⨯⨯-=n t t n n l xB V (8-2-1)式中系数阵B 为列满秩矩阵,其秩为t B R =)( 。
在最小二乘准则下得到的法方程为0ˆ11=-⨯⨯⨯t t tt bb W xN (8-2-2)由于其系数阵的秩为t B R PB B R N R Tbb ===)()()(,所以bb N 为满秩矩阵,即为非奇异阵,具有凯利逆bb N 1-,因此具有唯一解,即W N xbb 1ˆ-= (8-2-3)当网中无起算数据时,网中所有点均为待定点,设未知参数的个数为u ,误差方程为111ˆ⨯⨯⨯⨯-=n u u n n l xB V (8-2-4)式中d t u +=d 为必要的起算数据个数。
尽管增加了d 个参数,但B 的秩仍为必要观测个数,即u t B R <=)(其中B 为不满秩矩阵,称为秩亏阵,其秩亏数为d 。
组成法方程0ˆ11=-⨯⨯⨯u u u u W xN(8-2-5)式中PlB W PB B N T u T uu ==⨯⨯1,,且u t B R PB B R N R T<===)()()(,所以N 也为秩亏阵,秩亏数为:t u d -=(8-2-6)由上式知,不同类型控制网的秩亏数就是经典平差时必要的起算数据的个数。
即有:⎪⎩⎪⎨⎧=测角网网测边网、边角网、导线水准网、测站平差,4,3,1d在控制网秩亏的情况下,法方程有解但不唯一。
也就是说仅满足最小二乘准则,仍无法求得xˆ的唯一解,这就是秩亏网平差与经典平差的根本区别。

工程热力学课后思考题答案__第四版_沈维道_童钧耕主编_高等教育出版社.
1.闭口系与外界无物质交换,系统内质量保持恒定,那么系统内质量保持恒定的热力系一定是闭口系统吗?不一定,稳定流动系统内质量也保持恒定。
2.有人认为开口系统内系统与外界有物质交换,而物质又与能量不可分割,所以开口系统不可能是绝热系。
对不对,为什么?不对,绝热系的绝热是指热能单独通过系统边界进行传递(传热量),随物质进出的热能(准确地说是热力学能)不在其中。
4.倘使容器中气体的压力没有改变,试问安装在该容器上的压力表的读数会改变吗?绝对压力计算公式p =p b +p g (p > p b ), p = p b -p v (p < p b )中,当地大气压是否必定是环境大气压?当地大气压p b 改变,压力表读数就会改变。
当地大气压p b 不一定是环境大气压。
6.经验温标的缺点是什么?为什么?不同测温物质的测温结果有较大的误差,因为测温结果依赖于测温物质的性质。
7.促使系统状态变化的原因是什么?举例说明。
有势差(温度差、压力差、浓度差、电位差等等)存在。
4题图9.家用电热水器是利用电加热水的家用设备,通常其表面散热可忽略。
取正在使用的家用电热水器为控制体(但不包括电加热器),这是什么系统?把电加热器包括在研究对象内,这是什么系统?什么情况下能构成孤立系统?不包括电加热器为开口(不绝热)系统(a 图)。
包括电加热器则为开口绝热系统(b 图)。
将能量传递和质量传递(冷水源、热水汇、热源、电源等)全部包括在内,构成孤立系统。
或者说,孤立系统把所有发生相互作用的部分均包括在内。
12.图1-22中容器为刚性绝热容器,分成两部分,一部分装气体,一部分抽成真空,中间是隔板,(1)突然抽去隔板,气体(系统)是否作功?(2)设真空部分装有许多隔板,逐个抽去p v1a b29题图隔板,每抽一块板让气体先恢复平衡在抽下一块,则又如何?(3)上述两种情况从初态变化到终态,其过程是否都可在p -v 图上表示?4.一刚性容器,中间用绝热隔板分为两部分,A 中存有高压空气,B 中保持真空,如图2-12所示。

2w电磁阀水阀
2w电磁阀水阀抽查情况及主要问题由于以称重传感器为核心部件的电子衡器产品,其准确度和可靠性即涉及到国内外贸易结算,又涉及到广大消费者利益,所以被原国家质量技术监督局于1999年列入《首批重点管理的计量器具目录》,并明确规定制造许可证的申请、考核和发证要严格按照国家规定办理。
2000年又发布了《衡器制造计量器具许可证考核必备条件》,其中称重传感器部分对生产规模、生产设施、检测设备等都有明确要求。
这样做的目的就是要求生产企业认真贯彻《计量法》,严格执行国家标准,不断提高称重传感器和电子衡器的质量水平。
然而事与愿违,由于种种原因,特别是恶性价格大战,无法无序的竞争,产品质量非但没有提高而且与国际同等产品的差距逐渐加大。
看看近几年国家监督抽查结果,你会更加感到称重传感器总体质量形势的严峻性。
1997年国家监督抽查14个企业共48只称重传感器,其中电子计价秤用15~20kg称重传感器33只,合格5只,合格率15%;电子汽车衡用20~25t称重传感器15只,合格3只,合格率20%,总合格率17%。
所抽产品全部合格的只有2个企业,占抽查企业的14%。
不合格主要原因是温度性能指标不符合要求。
2000年国家监督抽查10省市31个企业93台15kg电子计价秤。
抽查企业占生产企业的30%,其产量占全国总一、产品[液压水位控制阀]的详细资料:产品型号:H142X产品名称:液压水位控制阀产品特点:H142X液压水位控制阀,是一种自动控制水箱、水塔液面高度的水力控制阀。
当水面下降超过预设值时,浮球阀打开,活塞上腔室压力降低,活塞上下形成压差。
在此压差作用下阀瓣打开进行供水作业:当水位上升到预设高度时,浮球阀关闭,活塞上腔室压力不断增大致l吏阀瓣关闭停止供水。
如此往复自动控制液面在设定高度,实现自动供水功能。

DLC气体顶压消防给水设备DLC0.95/30-18说明书上海连成(集团)有限公司上海市嘉定区曹安公路3616-36181. 概述建筑消防供水常采用气压罐来代替高位水箱,满足10min消防初期用水量,但往往选用普通气压罐要占据较大空间。
DLC系列消防气体顶压给水设备是以GB/T50016《建筑设计防火规范》;以GA30.4《固定消防给水设备的性能要求和试验方法第4部分:消防气体顶压给水设备》、Q/IFNM 9《消防气体顶压给水设备》为标准生产的新型固定灭火装置。
该装置由气压水罐、稳压装置、集装装置、止气装置、电控系统等组成,其罐体容积是普通气压罐的1/3~1/5,供水压力平稳,是较理想的大型应急消防气压给水设备。
2. 环境条件DLC系列产品适合在下列环境中工作:(1) 环境温度:5~40℃;(2) 空气相对湿度:≤85%(20±5℃时);(3) 介质温度4~70℃;(4) 供电电压:380V(+5% -10%)3. 型号意义4. 工作原理补水泵工作时将水送至给水管网,多余的水进入气压罐,当液位达到设定值SN3时,稳压水泵停止工作,此时系统压力并未达到设定压力值,稳压空压机开始运行;当压力升至稳压压力上限SP2时,稳压空压机便停止运行。
由于系统泄漏等原因造成管网压力下降,当管网压力下降至稳压压力下限SP1时,若液位探测器在设定值SN2点检测为水,则重复稳压空压机运行;若液位探测器在设定值SN2点检测不到水,则重复补水泵运行,如此周而复始。
当发生火情时消防装置投运,稳压装置无法维持管网压力,当压力降至SP3时或消防信号输入,气体顶压装置工作将气压罐里的水顶入消防管网,并向管网提供10min的消防用水。
当液位下降到设定值SN1时,止气装置关闭,防止气压罐中的气体进入消防管网。
设备消防结束。
