新概念英语第二册课后习题答案详解Lesson 11. b选b最为正确。
因为a.d.都与课文内容不符合，也不合乎逻辑；c.的意思是“他们没有注意他”，而作者的意图并不是想让他们注意他，而是想让他们停止谈话。
所以选b. 最能表达作者当时心里的感受。
2．c其余3个答案都与原句意思不符合。
3．b因为 a. to 不对，可以是He went to the theatre;c. into 也不对，可以是He went into the theatre;d. on更不符合语法，表示在某一个地方用介词in 或at, in 表示在大的空间，如国家，城市等，at 则表示在小的地点或空间，如atthe office, at the theatre 等, 所以选b.是正确的。
4．db. above(在……上方)；c. ahead of (在……的前面，在……之前)不和behind 对应，也不强调位置的前后顺序。
a. before 和d. infront of 都是和behind 对应的，都有“在……前面”的意思。
但in front of 更具体的强调位置，而before则包含更宽泛的意思，即时间上，空间，次序，登记，重要性方面的“在……前面”5．c因为用a. Where, b. why, d. when 提问都不符合逻辑，都不是针对状态提问的，只有How提问，才能用Angry回答。
6．ab. they 只做主语；c. their只能做定语；d. us 虽然可以做宾语，但与前一句意思不符合。
7．da. none是代词，很少用在名词前面；b. any 只能用在否定句或疑问句中；c. not any 不符合语法，因为前面没有助动词did.8.ba. chair(椅子)， c. armchair(手扶椅) d. class(班级) 这3个选择都和seat的意思不符合。
Seat是”座位，座席”的意思。
强调的是可供坐下的地方，不是具体的椅子。
Valtek MaxFlo 4 Eccentric Rotary Plug Control Valv
Valtek MaxFlo 4 Eccentric Rotary Plug Control ValveMaxFlo 4 Eccentric Rotary Plug Control Valve2The Flowserve Valtek MaxFlo 4 control valve is a high performance eccentric rotary plug valve designed for the process industry. It features a large capacity, standard hardened trim and superior shaft blow-out protection. This valve is available in sizes 1 through 12 inches, ASME Class 150, 300 and 600 as well as DIN PN 10, PN16, PN 25, PN40 and PN63.An optional ISA 75.08.01 or DIN EN 558 series 1 long-pattern body makes this valve an easy drop-in replacement for a globe control valve.The MaxFlo 4 is suitable for most applications; its control valve features include:• Highest Rated Cv • Precise Control • Reliable Shut-off• Most Current Safety Standards • Fugitive Emissions Elimination •Integral Noise Reduction PlatesHighest Rated CvThe unique design of the MaxFlo 4 shaft and plug provide as much as 70% more Cvcompared to the competition. This allows customers to get more flow when neededand sometimes allows for a smaller, more economical valve to be used.Precise ControlThe MaxFlo 4 polygon connection between the shaft and plug is a proven superiormethod for making demanding mechanical connections that are stronger, more preciseand have a substantially longer service life. This reduces backlash and the high strengthof the polygon connections makes them capable of withstanding greater shock loadsunder extreme torque reversal conditions.Reliable Shut-offThe MaxFlo 4 double-offset eccentric plug rotates into the seat at an angle that eliminatessliding over the seat surface. This design reduces seat wear, and thereby decreases main-tenance requirements and costs. At the same time, a tight ANSI Class VI shutoff is easilyobtainable using the soft seat design.Safety StandardThe shaft is designed to meet the safety requirements of industry standard ASME B16.34to ensure that the shaft is retained even if the actuator is removed when the valve is stillpressurized. This is standard on every MaxFlo 4 to provide our customers with confidenceand safety.3Separate bonnet ensures positive anti-blowout, accommodates multiple packing options, and offers flexibility in material selection for demandingapplications.Heavy-duty rigid metal seat,with hardfaced or soft-seat options, provides tighter shutoff, and easier maintenance. Available in full area and several reductions in every size to suit your process needs.Blow out proof shaft required by ASME B16.34 2004 Sec 6.5 ensures safety. Standard on every MaxFlo 4.An economical flangeless configuration of the MaxFlo 4 is also available. The standard flanged body is the same length. To replace existing globe valves we offer the flanged body with the same face to face length as a globe valve (Per ISA 75.08.01).4Open Flow Path gives as much as 70%more C v than competitive valves that have the shaft obstructing the flow. In many cases it is possible to use a smaller, more economical MaxFlo 4.Flanged end post allows for easy maintenance.Hard stainless steel plug requires no breakout torque and increases valve life as the plug lifts off the seat immediately when it begins rotating.Precision NC machined plug and shaft significantly reduces maintenance costs byallowing replacement of only the necessary parts.Polygon shaft/plug connection for precise robust control.Shimless seat offers simplified assembly and easy maintenance.5Eliminate Fugitive EmissionsSpecial Flowserve packing sets, such as SureGuard XT live loaded packing, are available to control fugitive emissions. Packing options include: PTFE V-Ring, Braided PTFE, Graphite, Sureguard XT, Garlock SVS, LATTYflon 3265 LM and LATTYgraf 6995 NG (meeting requirements for TA-Luft, ISO 15848-1 class B and A, and EPA standards).Integral Noise-Reduction Plate OptionDesigned to reduce noise levels by 5 to 10 dBA, our integral plate fits into the valve body. It can be easily maintained using the same tools required for the seat retainer. It is perfectly suitable with all gases in the shaft-downstream direction, and the plate does not change the length of the valve.Integrated Control Valve SolutionOperated by a diaphragm, piston, or rack-and-pinion actuator coupled with a Logix digital positioner, the MaxFlo 4 maintains high positioning accuracy, repeatability, controlled high speed and reliable response. With the advanced diagnostic solutions that can be seamlessly integrated into a host control and/or plant asset management system, along with state-of-the-art features and performance, the MaxFlo 4 is the most economical Eccentric Rotary Plug valve in the market.NR Diaphragm Rotary ActuatorThe Flowserve NR diaphragm rotary actuator is a rugged single-acting actuator designed to provide high performance, long life and reliability. The diaphragm actuator is very sensitive to small changes in air supply, which allows it toprecisely move the valve plug without over shoot.6Logix 3000MD+ Digital PositionerEasiest calibration and configuration of any positioner available.

After consultation with stakeholders in both countries, Standards Australia and Standards New Zealand decided to develop this Standard as an Australian Standard rather than an Australian/New Zealand Standard.The AS 3894 series provides information on a number of test procedures that are frequently used in the field to determine the adequacy of site-applied protective coating.These test methods may be used where it is inappropriate to adopt test methods described in the AS/NZS 1580 series, which may be better suited for laboratory applications.LIST OF METHODS Number inseriesASTitle 3894.1Non-conductive coatings—Continuity testing—High voltage (brush) method 3894.2Non-conductive coatings—Continuity testing—Wet sponge method 3894.3Determination of dry film thickness 3894.4Assessment of degree of cure 3894.5Determination of surface profile 3894.6Determination of residual contaminants 3894.7Determination of surface temperature and dew point 3894.8Visual determination of gloss 3894.9Determination of adhesion 3894.10Inspection report—Daily surface and ambient conditions 3894.11Equipment report 3894.12Inspection report—Coating 3894.13Inspection report—Daily 3894.14Inspection report—Daily painting s e d b y U N I V E R S I T Y O F S O U T H A U S T R A L I A o n 20 M a y 2008AS 3894.0—20022NOTESs e d b y U N I V E R S I T Y O F S O U T H A U S T R A L I A o n 20 M a y 2008Standards AustraliaStandards Australia is an independent company, limited by guarantee, which prepares and publishes most of the voluntary technical and commercial standards used in Australia. These standards aredeveloped through an open process of consultation and consensus, in which all interested parties are invited to participate. Through a Memorandum of Understanding with the Commonwealth government,Standards Australia is recognized as Australia’s peak national standards body.Australian StandardsAustralian Standards are prepared by committees of experts from industry, governments, consumers and other relevant sectors. The requirements or recommendations contained in published Standards are a consensus of the views of representative interests and also take account of comments received from other sources. They reflect the latest scientific and industry experience. Australian Standards are kept under continuous review after publication and are updated regularly to take account of changing technology.International InvolvementStandards Australia is responsible for ensuring that the Australian viewpoint is considered in the formulation of international Standards and that the latest international experience is incorporated innational Standards. This role is vital in assisting local industry to compete in international markets.Standards Australia represents Australia at both ISO (The International Organization for Standardization) and the International Electrotechnical Commission (IEC).Electronic Standards All Australian Standards are available in electronic editions, either downloaded individually from our Web site, or via on-line and CD ROM subscription services.

OPLA ... absorption, A m ... absorption measured by detector ε ... Extinction coefficient c ... Concentration OPL ... Optical path lengthA light source emits radiation through the medium and the incident radiation is measured on the detector side.Once the light has passed through a filter for wavelength selection, the intensity of the light is determined by a photodiode and converted to a photocurrent.The subsequent conversion to transmission (%) or absorbance units (AU, OD) is performed in the associated transmitter.1Absorption measurement with reference 1Light source 2Optical windows 3Measurement filter 4Measuring detector 5Lens 6Medium flow 7Reference filter 8Reference detectorMeasuring system An optical measuring system comprises:•Sensor (photometer) OUSAF44•Liquiline CM44P transmitter •Cable set CUK80•Assembly to suit the sensor, e.g. OUA260OUSAF44Endress+Hauser 31pipe 5Flow assembly OUA2602Transmitter CM44P 6Sensor: light source (lamp)3Cable set CUK807Cable set CUK804Sensor: detector InputMeasured variableUV absorption Measuring range •0 to 2.5 AU •Max. 50 OD (depending on the optical path length)WavelengthDiscrete wavelength at 254, 280, 295, 302, 313 or 365 nmMore available on request Power supplyElectrical connection The sensor is connected to the transmitter using the pre-terminated or labeled cable set CUK80 (for connection to CM44P) or OUK40 (for connection to CVM40). The terminals and labeling may vary depending on the transmitter in use. The cable set must be ordered separately.OUSAF444Endress+Hauser3OUSAF44 connecting cable ALight source (lamp) power supply B Signals of measurement and reference detectorCable lengthMaximum 100 m (330 ft)Versions for use in hazardous areas Safety instructions for electrical apparatus in explosion-hazardous areas, XA01403CConnecting the detector using a safety barrierThe photometer sensors use silicon photovoltaic cells as detectors which are operated in the current mode. The detectors are intrinsically safe and can be deployed in Zone 1 environments.The safe area is separated from the hazardous area by one safety barrier MTL7760AC.OUSAF44Endress+Hauser 5The safety barrier may only have a very low leak current since the optical signals from the sensor can be in the nanoampere range. Therefore, the sensor cable shield is connected to the ground terminal of the barrier.On delivery, the CUK80 detector cable is permanently wired to the safety barrier. All you have to do is simply connect the individual cable ends to the detector and transmitter.Connecting the hazardous area lamp using a junction boxThe hazardous area lamp (EXP-1) must be connected to the transmitter using a certified junction box.For versions with FM approval, the junction box is included in the delivery and already pre-terminated on the lamp side. You simply have to connect the cable of the transmitter (CUK80)to the terminals of the junction box.For versions with ATEX approval, the junction box is not included in the delivery and it and the cable glands required must be provided by the customer at the place of installation. You must connect the cables entirely on your own (CUK80 of transmitter and lamp cable of photometer sensor).OUSAF446Endress+Hauser5Connecting the hazardous area lamp to CM44P using a junction boxInstallationInstallation instructions6Mounting angles.

w = weighting r = cost of debt or equity e = equity and d = debt t = tax rate (interest is tax-deductible)
WACC example
End
Acme PLC has a cost of equity of 15% and a cost of debt of 6%. Acme PLC has a target capital structure comprising of 65% equity and 35% debt. The tax rate is 25%. Calculate the weighted average cost of capital.
Shareholders bear the highest risk.
Weighted average cost of capital (WACC)
The costs of the various sources of capital are weighted according to the proportions of the sources of capital to overall capital.
Inflation causes money in the future to be worth less than it is at present.
Lenders and shareholders bear a risk that they may not be paid back the money they have lent or invested should the organisation go bankrupt.
WACC = (15% X 65%) + (6% X 35% X 75%) WACC = 11.3%
Cost of equity - CAPM
Exprate plus a premium for bearing the company’s market risk. Ri = Rf + β(Rm – Rf); where Ri = return expected on the company Rm = return expected on the market β = sensitivity of the company’s return to changes in the market return
Capital budgeting Cost of capital
Introduction
Organisations require funding in order to make capital investments. This funding is obtained from the owners or by borrowing. This funding has a cost whether the interest due to the lenders or the return expected by the shareholders. A capital investment should be sufficient to compensate these providers of funds.
Elements of the required return
People prefer to have money today rather than at some point in the future so need to be compensated for the delay in receiving money.
Beta examples
Unlevering beta
The calculated betas reflect some level of financial risk that is unlikely to be applicable to another company that is looking to base its beta on a comparable company. The beta of the comparable company will need to be unlevered by removing the debt element of the beta thereby deriving an asset beta. This asset beta will then need to be levered to reflect the financial risk of the using company.
