VU和db是两种音量单位

VU和db‎是两种音量‎单位，0VU相当‎于-3dB，vu是对音‎量进行了加‎权处理，它的值比较‎接近人耳的‎听感，而db就比‎较精确。

0UV=4dB.我们的播控‎都用0UV‎做为标准，而演播室以‎0DB作为‎标准，有点乱。

另外关于音‎量有效值电‎平指示的响‎应也不同，有的设备已‎经过了，但有的设备‎还在0UV‎以下。

估计也是由‎于厂方有不‎同的标准的‎缘故。

VU表反映‎的是信号的‎平均值，这种表对声‎音信号电平‎的骤变反映‎比较迟钝。

PPM表是‎峰值节目表‎，它能快速扑‎捉到信号包‎络的变化，但它有指示‎值下降时间‎的设置，为了便于观‎察。

基本换算公‎式：0VU=+4dBu=-8PPU （在1KHz‎稳态信号下‎）dB是个相‎对度量单位‎，如果没有0‎d B的基准‎说明，dB值表达‎的意义是不‎确定的。

当然，由于有明确‎的定义，dBu、dBm、dBV这些‎单位都是有‎绝对的值所‎对应的。

VU作为一‎个平均值度‎量单位，总之接近人‎耳的听觉响‎应特点，符合人耳“确切“的听觉响应‎。

一般情况下‎，VU与dB‎u的对应关‎系为0VU‎=+4dBu，但0VU是‎否为一个绝‎对值，我一直存有‎疑问，我觉得0V‎U更可能也‎是一个相对‎值（这一点未经‎权威资料证‎实，提出来供商‎榷），理由如下：1、VU表刻度‎是不均匀的‎，如0VU为‎绝对值，则过大、过小音频信‎号很难在面‎板上精确表‎现出来，而各传输环‎节的音量大‎小往往不太‎一致，我所知道的‎一个电台光‎纤发送端0‎V U就设为‎+2dBu。

2、我单位使用‎的Logi‎t ekVU‎表使用说明‎书中便指出‎，该设备在出‎厂时0VU‎设定在+4dBu，隐含这个值‎可重新加以‎设定的意思‎。

数字音频设‎备的满度电‎平本标准规定‎了广播电视‎数字音频系‎统中，节目制作、播出及传输‎系统数字设‎备的满度电‎平值。

本标准适用‎于广播电视‎数字音频系‎统，其他数字音‎频系统可参‎照执行。

The TPS54620 implements asplit input power rails with separate input voltage inputs for the power stage and control circuitry. The power stage input (PVIN) is rated for 1.6 V to 17 V while the control input (VIN) is rated for 4.5 to 17 V. TheTPS54620EVM-374 provides both inputs but is designed and tested using the PVIN connected to VIN. Rated input voltage and output current range for the evaluation module are given in Table 1-1. This evaluation module is designed to demonstrate the small printed-circuit-board areas that may be achieved when designing with the TPS54620 regulator. The switching frequency is externally set at a nominal480 kHz. The high-side and low-side MOSFETs are incorporated inside the TPS54620 package along with the gate drive circuitry. The low drain-to-source on resistance of the MOSFET allows the TPS54620 to achievehigh efficiencies and helps keep the junction temperature low at high output currents. The compensation components are external to the integrated circuit (IC), and an external divider allows for an adjustable output voltage. Additionally, the TPS54620 provides adjustable slow start, tracking and undervoltage lockout inputs. The absolute maximum input voltage is 20 V for the TPS54620EVM-374.1.2 Performance Specification SummaryA summary of the TPS54620EVM-374 performance specifications is provided in Table 1-2. Specifications are given for an input voltage of V IN = 12 V and an output voltage of 3.3 V, unless otherwise specified. TheTPS54620EVM-374 is designed and tested for V IN = 8 V to 17 V with the VIN and PVIN pins connect together with the J3 jumper. The ambient temperature is 25°C for all measurements, unless otherwise noted.1.3 ModificationsThese evaluation modules are designed to provide access to the features of the TPS54620. Some modifications can be made to this module.2TPS54620 Step-Down Converter Evaluation Module User's Guide SLVU281B – MAY 2009 – REVISED AUGUST 20211.3.1 Output Voltage Set PointThe output voltage is set by the resistor divider network of R8 and R9. R9 is fixed at 10 kΩ. To change the output voltage of the EVM, it is necessary to change the value of resistor R8. Changing the value of R8 can change the output voltage above 0.8 V. The value of R8 for a specific output voltage can be calculated using Equation 1.)OUT k V -V R V10W(0.88=0.8(1)Table 1-3 lists the R8 values for some common output voltages. Note that V IN must be in a range so that the minimum on-time is greater than 120 ns, and the maximum duty cycle is less than 95%. The values given in Table 1-3 are standard values, not the exact value calculated using Equation 1.1.3.2 Slow Start TimeThe slow start time can be adjusted by changing the value of C7. Use Equation 2 to calculate the required value of C7 for a desired slow start timeTss(ms)Iss(μA)C7(nF)=Vref(V)´(2)The EVM is set for a slow start time of 4 msec using C7 = 0.01 µF.1.3.3 Track InThe TPS54620 can track an external voltage during start up. The J5 connector is provided to allow connection to that external voltage. Ratio-metric or simultaneous tracking can be implemented using resistor divider R5 and R6. See the TPS54620 data sheet (SLVS949) for details.1.3.4 Adjustable UVLOThe under voltage lock out (UVLO) ca be adjusted externally using R1 and R2. The EVM is st for a start voltage of 6.521 V and a stop voltage of 6.065 V using R1 = 35.7 kΩ and R2 = 8.06 kΩ. Use Equation 3 and Equation 4 to calculate required resistor values for different start and stop voltages.ENFALLING START STOPENRISING ENFALLING p h ENRISING V V -V V R1=V I 1-+I V æöç÷èøæöç÷èø(3)ENFALLINGSTOP ENFALLING p h R1×V R2=V -V +R1(I +I )(4) IntroductionIntroduction 1.3.5 Input Voltage RailsThe EVM is designed to accommodate different input voltage levels for the power stage and control logic. During normal operation, the PVIN and VIN inputs are connected together using a jumper across J3. The single input voltage is supplied at J1. If desired, these to input voltage rails may be separated by removing the jumper across J3. Two input voltages must then be provided at both J1 and J2. Test Setup and Results2 Test Setup and ResultsThis section describes how to properly connect, set up, and use the TPS54620EVM-374 evaluation module.The section also includes test results typical for the evaluation module and covers efficiency, output voltage regulation, load transients, loop response, output ripple, input ripple, and start-up.2.1 Input / Output ConnectionsThe TPS54620EVM-374 is provided with input/output connectors and test points as shown in Table 2-1. A power supply capable of supplying 4 A must be connected to J1 through a pair of 20 AWG wires. The jumper acrossJ3 must be in place. See Section 1.3.5 for split input voltage rail operation. The load must be connected toJ7 through a pair of 20 AWG wires. The maximum load current capability must be 6 A. Wire lengths must be minimized to reduce losses in the wires. Test-point TP1 provides a place to monitor the V IN input voltages with TP2 providing a convenient ground reference. TP8 is used to monitor the output voltage with TP9 as the ground reference.Test Setup and Results 2.2 EfficiencyThe efficiency of this EVM peaks at a load current of about 2 A and then decreases as the load current increasesshows the efficiency for the TPS54620EVM-374 at an ambient temperature of 25°C.towards full load. Figure 2-1Figure 2-2 shows the efficiency for the TPS54620EVM-374 at lower output currents below 0.10 A at an ambienttemperature of 25°C.The efficiency may be lower at higher ambient temperatures, due to temperature variation in the drain-to-source resistance of the internal MOSFET. Test Setup and Results 2.3 Output Voltage Load Regulationshows the load regulation for the TPS54620EVM-374.Figure 2-3Measurements are given for an ambient temperature of 25°C.2.4 Output Voltage Line RegulationFigure 2-4shows the line regulation for the TPS54620EVM-374.2.5 Load TransientsFigure 2-5 shows the TPS54620EVM-374 response to load transients. The current step is from 25% to 75% of maximum rated load at 12 V input. Total peak-to-peak voltage variation is as shown, including ripple and noiseon the output.Figure 2-5.

TPS54620EVM-374 Output Ripple2.8 Input Voltage RippleFigure 2-8 shows the TPS54620EVM-374 input voltage. The output current is the rated full load of 4 A and V IN =12 V. The ripple voltage is measured directly across the input capacitors.Figure 2-8. TPS54620EVM-374 Input Ripple Test Setup and ResultsTest Setup and Results 2.9 Powering UpFigure 2-9 and Figure 2-10 show the start-up waveforms for the TPS54620EVM-374 . In Figure 2-9, the output voltage ramps up as soon as the input voltage reaches the UVLO threshold as set by the R1 and R2 resistor divider network. In Figure 2-10, the input voltage is initially applied and the output is inhibited by using a jumper at J2 to tie EN to GND. When the jumper is removed, EN is released. When the EN voltage reaches theenable-threshold voltage, the start-up sequence begins and the output voltage ramps up to the externally set value of 3.3 V. The input voltage for these plots is 12 V and the load is 1Ω.Figure 2-9. TPS54620EVM-374 Start-Up Relative to VIN Array Figure 2-10.

The peak temperature of the IC (70°C) is well below the maximum recommended operating condition listed in the data sheet of 150°C.Figure 2-11. TPS54620EVM-374 Thermal ImageBoard Layout 3 Board LayoutThis section provides a description of the TPS54620EVM-374 , board layout, and layer illustrations.3.1 LayoutThe board layout for the TPS54620EVM-374 is shown in Figure 3-1 through Figure 3-5. The topside layer of the EVM is laid out in a manner typical of a user application. The top, bottom and internal layers are 2-oz. copper. The top layer contains the main power traces for PVIN, VIN, V OUT, and VPHASE. Also on the top layer are connections for the remaining pins of the TPS54620 and a large area filled with ground. The bottom and internal ground layers contains ground planes only. The top side ground traces are connected to the bottom and internal ground planes with multiple vias placed around the board including two vias directly under the TPS54620 device to provide a thermal path from the top-side ground plane to the bottom-side ground plane.The input decoupling capacitors (C2, and C3) and bootstrap capacitor (C5) are all located as close to the ICas possible. In addition, the voltage set-point resistor divider components are also kept close to the IC. The voltage divider network ties to the output voltage at the point of regulation, the copper V OUT trace at the J7 output connector. For the TPS54620, an additional input bulk capacitor may be required, depending on the EVM connection to the input supply. Critical analog circuits such as the voltage setpoint divider, frequency set resistor, slow start capacitor and compensation components are terminated to ground using a wide ground trace separate from the power ground pour.

|PTE7300I²C PRESSURE SENSORInstallation & Communication GuideDescriptionThe PTE7300 pressure sensor is the ideal customer solution for challenging measuring requirements for general applications in the mid and high-pressure ranges. The PTE7300 features a wide range of ports and provides an I2C digital pressure output.ElectricalPressure Ranges 0-16 bar to 0-600 bar (0-230 psi to 0-8700 psi)Pressure Reference Gauge (Module) and Sealed Gauge (fully hermetic sensor) Supply Voltage 2.7VDC to 5.5VDCDigital Interface I2C with CRC (memory integrity, and data transmission) Device Address 0xDA (including CRC)0x6C (excluding CRC)Operating Current In SleepMode6.5 uA (typical)Operating Current In ActiveMode3.7mA typical (4mA maximum)Available Data PressureBridge temperature*Status synchronizedDevice serial (int16, at address 0x30) min./max. of span mapped to ±16000 bit value(int16, at address 0x2E)-40̊C..+125̊C mapped to±16000 bit value(uint16, at address 0x32) (uint32, at address 0x50 (low word), and address 0x52 (high word))Resolution Note: Sensata offers a C++ library available on request that is written on Arduino platform, which allows for plug-n-play sensor control and is easy to port to other platforms.15 bitResponse Time (default) < 1 msProbe Configurations Continuous or On-demand / single cycle*Note: the bridge temperature is not part of the production quality control routines. Sensata will not guarantee any performance ratings for the sensor’s temperature output. For accurate and reliable temperature measurement, it’s advised to use a different sensor with qualified temperature output.Typical Application CircuitNote: the pull-up resistor resistance values and cable length highly depend on the application. Typical pull-up resistors are 4.7kOhm for a cable between 1-2 meters. Please note that, in general, a low internal resistance and low internal capacitance cable will increase the action radius since, in that case, the voltage is dropping less over distance. Also, lowering the resistancevalues increases the current which sharpens the edges of the digital communication signals, but at costof power consumption when communicating with the device.I 2C outputPTE7300 SERIESContents1Pin Assignments (5)2Pin Descriptions (5)3Absolute Maximum Ratings (5)4I2C interface (6)4.1 Device Address (6)4.2 Command Format (7)4.3 System Operation Modes and State Diagram (9)4.4 I2C Bus Timing (9)5Revision History (10)1 PIN ASSIGNMENTSFigure 1.

An external I 2C parent (e.g. a μC) can read and write all memory addresses (registers) of the device using the following commands:• Random write: Sets a memory address and writes data to consecutive memory addresses of the device starting at the set memory address.• Random read: Sets a memory address and reads data from consecutive memory addresses of the device starting at the set memory address.• Read last: Reads data from the device starting at the last memory address set by the parent. This facilitate s repeated reading of the same memory addresses without transmitting a memory address first.All read/writes must start at word aligned addresses (i.e. LSB of memory address equals 0) and read/write an even number of bytes . Maximum length for CRC protected read/writes is 4 bytes.4.1 Device AddressTable 4.

Their polynomials are:•CRC4 polynomial 0x03, initialization value 0x0F•CRC8 polynomial 0xD5, initialization value 0xFFIf the CRC4 sent by the I2C parent does not match the CRC4 calculated by the I2C child, the I2C frame is aborted by not sending an acknowledge bit from the child after the CRC4. Additionally, the CRC4 error is reported as the event bit 11 at the STATUS register. If a command is aborted by a CRC4 error, no ‘read last’ command must follow.4.3System Operation Modes and State DiagramSystem balances performance and current consumption by different operation mode configurations.

M-511⁄8 DIN Digital Panel RTD MetersThe DP63000-RTD meter accepts standard RTD inputs and precisely linearizes them into temperature readings. A full 4-digit display accommodates a wide range of temperature inputs. State-of-the-art digital circuitry virtually eliminates errors due to drift. The meter features a readout choice of either Fahrenheit or Celsius with 0.1 or 1° resolution. Display prompts and front panel buttons aid the operator through set-up and operation. Programmable digital filtering enhances the stability of the reading. All set-up data is stored in EEPROM, which will hold data for a minimum of 10 years without power. The meter provides a peak “HI” and valley “LO” reading memory with selectable capture delay time. The capture delay is used to prevent detection of false peak or valley readings that may occur during start-up or unusual process events. The peak and valley readings areDP63200-RTDU RTD Meter U 4-Digit, 14.2 mm (0.56") LEDU Accepts Standard 3-Wire 100 Ω RTD Sensors (ALPHA = 0.00385 or ALPHA =0.00392) U Conforms to ITS-90 StandardsU Selectable °F or °C with 0.1 or 1 Degree Display Resolution U P rogrammableTemperature Offset U Programmable Digital FilteringU Peak/Valley (High/Low Reading) Memory U NEMA 4X (IP65) Sealed Front BezelU Custom Units Overlay with BacklightOrdering Example: DP63200-RTD, RTD input, 85 to 250 Vac, 50/60 Hz.stored at power-down, allowing process limits to be monitored over any length of time.

LM4926LM4926 Ground-Referenced, Ultra Low Noise, Fixed Gain, 80mW Stereo Headphone AmplifierLiterature Number: SNAS266B芯天下--/LM4926OBSOLETEOctober 3, 2011Ground-Referenced, Ultra Low Noise, Fixed Gain, 80mW Stereo Headphone AmplifierGeneral DescriptionThe LM4926 is a ground referenced, fixed-gain audio power amplifier capable of delivering 80mW of continuous average power into a 16Ω single-ended load with less than 1% THD +N from a 3V power supply.The LM4926 features a new circuit technology that utilizes a charge pump to generate a negative reference voltage. This allows the outputs to be biased about ground, thereby elimi-nating output-coupling capacitors typically used with normal single-ended loads.The LM4926 features an Automatic Standby Mode circuitry (patent pending). In the absence of an input signal, after ap-proximately 12 seconds, the LM4926 goes into low current standby mode. The LM4926 recovers into full power operat-ing mode immediately after a signal is applied to either the left or right input pins. This feature saves power supply current in battery operated applications.Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components. The LM4926 does not require output coupling capacitors or bootstrap capacitors, and therefore is ideally suited for mobile phone and other low voltage appli-cations where minimal power consumption is a primary re-quirement.The LM4926 features a low-power consumption shutdown mode selectable for either channel separately. This is accom-plished by driving either the SD_RC (Shutdown Right Chan-nel) or SD_LC (Shutdown Left Channel) (or both) pins with logic low, depending on which channel is desired shutdown.Additionally, the LM4926 features an internal thermal shut-down protection mechanism.The LM4926 contains advanced pop & click circuitry that eliminates noises which would otherwise occur during turn-on and turn-off transitions.The LM4926 has an internal fixed gain of 1.5V/V.Key Specifications■ Improved PSRR at 217Hz 70dB (typ)■ Power Output at V DD = 3V,R L = 16Ω, THD ≦ 1%80mW (typ)■ Shutdown Current 0.01µA (typ)■ Internal Fixed Gain 1.5V/V (typ)■ Operating Voltage1.6V to 4.2V Features■Ground referenced outputs ■High PSRR■Available in space-saving micro SMD package ■Ultra low current shutdown mode■Improved pop & click circuitry eliminates noises during turn-on and turn-off transitions■No output coupling capacitors, snubber networks,bootstrap capacitors, or gain-setting resistors required ■Shutdown either channel independentlyApplications■Notebook PCs ■Mobile Phone ■PDAs■Portable electronic devices ■MP3 PlayersBoomer ® is a registered trademark of National Semiconductor Corporation.© 2011 National Semiconductor Corporation 201161201161 Version 3 Revision 2Print Date/Time: 2011/10/03 14:38:25LM4926 Ground-Referenced, Ultra Low Noise, Fixed Gain, 80mW Stereo Headphone Amplifier201161b8FIGURE 1.

2011-2012年全球及中国镍行业研究报告2011年，受英美资源Barro Alto镍项目、淡水河谷Onça Puma 镍项目等建成投产，以及中国含镍生铁产量快速增加等因素影响，全球镍产量同比增长10.0%，至100%158.9万吨；消费量同比增长6.9%，至157.2万吨。

2012年，世界各地镍项目的陆续投产以及新增产能的释放，将使镍供应过剩的压力进一步加大，预计全年镍过剩5.0万吨。

与全球镍供需格局不同，中国镍市一直处于供不应求的局面。

2011年中国不锈钢产量同比增长11.9%，极大地刺激了镍的消费，全年镍消费量同比增长17.1%，远高增极大刺激镍消费年镍消费增高于同期世界镍消费增速。

与此同时，中国镍产量也在大幅提升，其中增长最快的是镍铁。

2010年，中国镍产量为32.6万吨，其中镍铁产量（含镍量）为16.1万吨，首次超过电解镍产量，成为中国产量最大的镍产品。

2011年，中国镍产量约为44.6万吨，其中电解镍、镍铁占比分别为41.5%和56.5%。

近年，中国镍铁市场飞速发展的主要原因有两点，一是不锈钢厂商对镍铁的使用比例不断提高，有的甚至达到50%以上。

二是镍铁冶炼工艺的进步。

目前先进且环保的回转窑—电炉（RKEF）工艺已经被镍铁行业接受，并成为主流。

在中国，镍铁生产所需的红土镍矿几乎全部依赖进口，2011年中国累计从印度尼西亚、菲律宾、澳大利亚等国进口镍矿砂及精矿4805.6万吨，同比增长92.4%，其中红土镍矿占比超过98%。

2012年，印尼正式宣布，从5月6日起48056924%对镍等14种原矿征收20%的出口税。

这一禁令的实施将使2012年中国红土镍矿的供应趋于紧张；同时助推镍价的上涨。

镍铁作为金属镍的替代产品，其价格难以摆脱LME镍价的控制。

2011年，LME镍价大幅下挫，随之国内镍价震荡下滑。

高、中镍铁也出现了不同程度的降价，而低镍铁由于受200系不锈钢需求增加的影响，价格不降反增。

《2011-2012年全球及中国镍行业研究报告》除了研究全球及中国镍市供需状况，镍价走势，镍铁市场外，还着重研究了Norilsk Nickel、Sale SA 等四家国际龙头企业，以及金川集团、吉恩镍业、新鑫矿业等7家中国重点生产商。

金川集团是中国最大的镍生产商，2011年镍产量为13.0万吨，位居全球第三。

吉恩镍业是中国第二大镍生产商，也是中国最大的镍盐生产商，公司主要产品为电解镍和硫酸镍，2011年这两大产品营业收入共占到公司总收入的62.85%。

新鑫矿业拥有丰富的镍矿资源，2011年旗下矿山镍金属量达到57.26万吨，全年生产电解镍8128吨，占到中国电解报告目录3.3.1 国内价格332第一章镍概述1.1 定义12 3.3.2 进口价格本章小结1.2 镍矿资源1.3 镍的冶炼第四章中国镍市场供需分析4.1 生产情况4.1.1 产量412第二章全球镍市场供需分析2.1 供应情况2.2 消费情况 4.1.2 产量构成4.2 消费情况4.2.1 消费量2.2.1 消费量2.2.2 消费结构本章小结4.2.2 消费结构4.2.3 不锈钢市场4.3 进出口分析第三章中国镍矿资源现状3.1 镍矿储量及分布4.3.1 进口4.3.2 出口5.2 中国镍价7.2.1 企业简介7.2.2 经营情况第六章中国镍铁市场分析6.1 镍铁概述6.2 供需现状7.2.3 在华发展7.3 BHP Billiton 7.3.1企业简介6.2.1 供应情况6.2.2 需求情况6.3 进出口现状7.3.2 经营情况7.3.3 在华发展7.4 Xstrata Plc 6.4 价格走势6.5镍铁行业面临的问题本章小结7.4.1 企业简介7.4.2 经营情况7.4.3 在华发展第七章国际镍重点企业研究7.1Norilsk Nickel 本章小结7.1 Norilsk Nickel 7.1.1 企业简介7.1.2 经营情况713第八章中国镍行业重点企业研究8.1 金川集团8.1.1 企业简介812.1.3 在华发展7.2 Vale SA8.1.2经营情况8.1.3 研发与投资8.2吉恩镍业8.2.1 企业简介8.5.3 研发与投资8.6广西银亿科技矿冶有限公司8.2.2 经营情况8.2.3 营收构成8.2.4 毛利率8.6.1 企业简介8.6.2 经营情况8.7陕西华泽镍钴金属有限公司8.2.5 投资分析8.3新鑫矿业8.3.1 企业简介8.7.1 企业简介8.7.2 经营情况本章小结8.3.2 经营情况8.3.3 毛利率8.3.4 镍矿开发进展8.4 中国镍资源8.4.1 企业简介8.4.28.4.2经营情况8.4.3 研发与投资8.5江西江锂科技有限公司851.5.1企业简介8.5.2经营情况图表目录•图：2000-2010年全球镍储量•表：2010年全球主要国家镍储量•表：2008年全球镍资源（分产品）分布•图：2004-2012年全球镍产量•表：2011年全球镍产量前十企业•图：20042012年全球镍消费量2004-2012•图：2007-2012年全球不锈钢粗钢产量及同比增长•图：2011年全球不锈钢粗钢（分产品）产量构成•图：2011年全球镍消费结构•表：2009-2012年全球镍供需平衡分析•图：中国镍矿资源主要类型及占比•图：中国镍矿储量（分省市）分布图中国镍矿储量（分省市）分布•图：2007-2012年中国镍矿砂及精矿进口量•表：2010-2011年中国镍矿砂及精矿（分国家）进口量及进口金额表：2011年中国镍矿砂及精矿进口额前10个省市表•图：2011年中国镍矿港口库存量•表：近年中国在东南亚投资的镍冶炼厂项目•图：2009-2012年中国红土镍矿价格走势•图：2009-2012年中国镍矿砂及精矿进口价格•图：2005-2011年中国镍产量•图：2007-2011年中国镍产量结构•图：2005-2011年中国镍消费量•图：2004-2010年中国镍消费结构•表：中国不锈钢冶炼用含镍原料的优劣势比较•图：2007-2012年中国不锈钢粗钢产量及同比增长•表：2011年中国不锈钢粗钢（分产品）产量及增速•图：2011-2012年中国300系列不锈钢卷板价格•图：2007-2012年中国精炼镍进口量•表：2009-2011年中国精炼镍（分国家/地区）进口量•表：2011年中国系列镍产品出口税率•图：2007-2012年中国精炼镍及合金出口量•表：2009-2012年中国精炼镍及合金（分国家/地区）出口量图：20112012年LME镍库存及现货价格•2011-2012•图：2011-2012年长江镍现货价格•图：中国红土镍矿分品位冶炼方法及镍铁产品分类•图：2007-2011年中国镍铁产量（含镍量）•图：2011年中国主要新建镍铁项目•图：2011年中国不锈钢（分产品）产量构成•表：2009-2012年中国镍铁进出口情况•表：2011年中国镍铁进口（分来源国）构成•表：2011年中国镍铁出口（分目的地）构成•图：2011-2012年中国镍铁价格走势•图：2011年中国高炉镍铁和电炉镍铁生产成本结构•表：Norilsk Nickel 矿山资源及储量•表：2005-2011年Norilsk Nickel 主要金属产量•图：2006-2010年Norilsk Nickel 总收入及毛利润•表：2009-2011年Norilsk Nicke主要产品收入图：20072011年Vale公司营业收入和净利润•2007-2011•表：2009-2011年Vale公司营业收入（分产品）构成•图：Vale镍生产子公司及分布表：20092011年Vale公司镍矿运营情况•2009-2011•表：2008-2011年Vale公司镍产量•图：2011年Vale公司镍销售额（分区域）构成•表：2011财年BHP Billiton （分产品）产量及同比增长•表：2010-2011财年BHP Billiton （分区域）镍产、销量•图：2006-2011年Xstrata plc收入及营业利润•表：2010-2011年Xstrata plc主要产品收入及同比增长•图：2009-2011年Xstrata plc 镍收入及营业利润•表：2009-2011年Xstrata plc 镍产量•表：2009-2011年Xstrata plc 镍销量•表：2011年全球TOP5企业镍产量及占比•表：金川集团基本情况•图：2007-2012年金川集团营业收入和利润总额•表：2007-2012年金川集团主要产品产量•表：吉恩镍业基本情况图：20082012年吉恩镍业主营业务收入和净利润•2008-2012•表：2010-2011年吉恩镍业主要产品收入及占比•表：2009-2011年吉恩镍业（分产品）毛利率•表：2011年吉恩镍业国内镍资源及储量•表：2011年吉恩镍业国外镍资源及储量•表：新鑫矿业基本情况•图：2007-2011年新鑫矿业营业收入和净利润•图：2006-2012年新鑫矿业电解镍产量•表：2009-2011年新鑫矿业（分产品）营业收入•图：2006-2011年新鑫矿业毛利率•表：2011年新鑫矿业镍资源量•表：2011年新鑫矿业镍储量•表：2009-2011年新鑫矿业镍矿冶炼能力•表：新鑫矿业基本情况•图：2006-2011年中国镍资源收入及净利润•表：江锂科技基本情况•表：银亿科技基本情况•表：华泽镍钴基本情况。
