高一数学 2.2函数的表示法(备课资料) 大纲人教版必修

●备课资料在近几年的高考题中,我们发现考查函数思想方法的题目较多,选用的题目经常源自生产、生活的实际,也经常用到函数的知识、方法及思想,这就要我们在对函数的学习中,一定要认识函数思想的实质,强化函数的应用意识.1.对函数知识、方法及思想的应用[例1]经市场调查,某商品在近100天内,其销售量和价格均是时间t 的函数,且销售量近似地满足关系g(t )=-31t +3109(t ∈N *,0<t ≤100),在前40天内价格为f (t )=41t +22(t∈N *,0≤t ≤40),在后60天内价格为f (t )=-21t +52(t ∈N *,40<t ≤100),求这种商品的日销售额的最大值(近似到1元).分析:弄清“日销量”“价格”“日销额”这三个概念以建立它们之间的函数关系式.解:前40天内日销售额为:S =(41t +22)(-31t +3109) =-121t 2+47t +77931 ∴S =-121(t -10.5)2+4837849 后60天内日销售额为:S =(-21t +52)(-31t +3109) =61t 2-6213t +35668 ∴S =61(t -106.5)2-2425 ∴得函数关系式S =⎪⎪⎩⎪⎪⎨⎧N ∈≤<--N ∈≤<+--*)10040(2425)5.106(61*)400(4837849)5.10(12122t t t t t t 且且 由上式可知:对于0<t ≤40且t ∈N *,有当t =10或11时,S max ≈809对于40<t ≤100且t ∈N *,有当t =41时,S max =714.综上所述得:当t =10或11时,S max ≈809答:第10天或11天日售额最大值为809元[例2]某中学高一年级学生李鹏,对某蔬菜基地的收益作了调查,该蔬菜基地种植西红柿,由历年市场行情得知,从2月1日起的300天内,西红柿市场售价与上市时间的关系用图一的一条折线表示;西红柿的种植成本与上市时间的关系用图二的抛物线段表示,试解答下列问题.(注:市场售价和种植成本的单位:元/102kg ,时间单位:天)(1)写出图一表示的市场售价间接函数关系P =f (t ).写出图二表示的种植成本与时间的函数关系式Q =g (t )(2)认定市场售价减去种植成本为纯收益,问何时上市的西红柿纯收益最大?解:(1)由图一可得市场售价间接函数关系为,f (t )=⎩⎨⎧≤≤-≤≤-)300200(,3002)2000(,300t t t t 由图二可得种植成本间接函数关系式为g (t )=2001(t -150)2+100,(0≤t ≤300) (2)设t 时刻的纯收益为h (t ),则由题意得h (t )=f (t )-g(t )即h (t )=⎪⎪⎩⎪⎪⎨⎧≤<-+-≤≤++-)300200(,21025722001)2000(,217521200122t t t t t t 当0≤t ≤200时,得h (t )=-2001(t -50)2+100 ∴当t =50时,h (t )取得在t ∈[0,200]上的最大值100; 当200<t ≤300时,得h (t )=-2001(t -350)2+100 ∴当t =300时,h (t )取得在t ∈(200,300]上的最大值87.5 综上所述由100>87.5可知,h (t )在t ∈[0,300]上可以取得最大值是100,此时t =50,即从2月1日开始的第50天时,上市的西红柿收益最大.评述:(1)以上两例都是考查用数学中函数知识思想、方法去解决实际问题的能力,注意其中关键词的理解,正确找出函数关系式.求最值时配方法是一种常用方法.(2)应用题是高考热点问题,且应用题的具体内容可以多种多样,千变万化,而抽象其数量关系,并建立函数关系式是具有普遍意义的方法.(3)数学应用题因其具有没有固定的背景与题型,难以摸拟分类的特点,也就更接近于我们的生产和实际生活.所以应用题是考查学生创新意识和创新能力的难得的有效题型,同时也不失为提高学生分析问题和解决问题能力的好题型.所以,我们广大师生应加强这一方面的训练,清除心理负面影响,以积极的姿态,迎接数学应用题的挑战,以适应高考的改革要求.二、“应用数学”的能力训练季节性服装当季节即将来临时,价格呈上升趋势,设某服装开始时定价为10元,并且每周(7天)涨价2元,5周后开始保持20元的价格平稳销售;10周后当季节即将过去时,平均每周削价2元,直到16周末,该服装已不再销售.(1)试建立价格P 与周次t 之间的函数关系式.(2)若此服装每件进价Q 与周次t 之间的关系为Q =-0.125(t -8)2+12,t ∈[0,16],t ∈N *.试问该服装第几周每件销售利润L 最大?解:(1)P = ⎪⎩⎪⎨⎧∈∈-∈∈∈∈+*]16,10[ ,240*]10,5[,20*[0,5) , 210N N N t t t t t t t t 且且且 (2)因每件销售利润=售价-进价,即L =P -Q 。

Suit-able for bonding materials relevant for direct glazing such as paints, glass, ceramic frits, painted and e-coated surfaces in commercial-vehicle production and repair.Curing of Sikaflex®-271 PowerCure is acceler-ated by Sika’s PowerCure technology which makes it largely independent of atmospheric conditions.PRODUCT BENEFITSAccelerated curing and adhesion build-up ▪Excellent application properties▪Ideal for glass replacement in commercial vehicles▪Low climate dependency of the curing speed with Sika® Booster ▪High mechanical strength ▪Solvent-free▪AREAS OF APPLICATIONSikaflex®-271 PowerCure is designed espe-cially for manual direct-glazing application, and vehicle-glass replacement in commercial vehicles. Thanks to the PowerCure Techno-logy Sikaflex®-271 PowerCure exhibits a fast strength and adhesion build-up.This product is suitable for experienced pro-fessional users only. Tests with actual sub-strates and conditions have to be performed to ensure adhesion and material compatibil-ity.1 / 2CURE MECHANISMSikaflex®-271 PowerCure cures by reaction with moisture provided by the accelerator paste and largely independent from atmo-spheric moisture. For typical strength build up data see table below.Time [h]Tensile lap-shear strength at23 °C [MPa]10.72 3.5Table 1: Strength build-up of Sikaflex®-271 PowerCure CHEMICAL RESISTANCESikaflex®-271 PowerCure is generally resistant to fresh water, seawater, diluted acids and di-luted caustic solutions; temporarily resistant to fuels, mineral oils, vegetable and animal fats and oils; not resistant to organic acids, glycolic alcohol, concentrated mineral acids and caustic solutions or solvents.METHOD OF APPLICATIONSurface preparationSurfaces must be clean, dry and free from grease, oil and dust. Surface treatment de-pends on the specific nature of the substrates and is crucial for a long lasting bond. All pre-treatment steps must be confirmed by pre-liminary tests on original substrates consider-ing specific conditions in the assembly pro-cess.ApplicationSetup the PowerCure Dispenser according to the PowerCure User Manual. If the applica-tion is discontinued for more than 2 minutes, the mixer needs to be replaced.Sikaflex®-271 PowerCure can be processed between 5 °C and 40 °C, but changes in react-ivity as well as application properties need to be considered. The optimum temperature for substrate and adhesive is between 15 °C and 25 °C.The open time is significantly shorter in hotand humid climates. The parts must always bejoined within the open time. As a rule ofthumb, a change of + 10 °C reduces the opentime by half.To ensure a uniform thickness of the bondlineit is recommended to apply the adhesive inthe form of a triangular bead (see figure 1).Figure 1: Recommended bead configurationRemovalUncured Sikaflex®-271 PowerCure can be re-moved from tools and equipment with Sika®Remover-208 or another suitable solvent.Once cured, the material can only be re-moved mechanically. Hands and exposed skinhave to be washed immediately using handwipes such as Sika® Cleaner-350H or a suit-able industrial hand cleaner and water. Donot use solvents on skin.FURTHER INFORMATIONThe information herein is offered for generalguidance only.

These devicesfeature a rugged alu m i n umenclosure small enough to mount onthe back panel of typical computerequipment, saving valuable deskand floor space. Isolation ispro v ided by optical couplers anda DC-to-DC converter. The RS232con n ec t ion is through male orfemale EIA 25-pin con n ec t ors. The RS485 connections are madethrough con v en i ent solderless screw terminals.The LDM485 series is designed forfull duplex op e ra t ion over two-wirepairs. Outputs are tri-state, allowing multidropping of up to 64 units.Hardware hand s hake is available over two separate wire pairs. Data rates are DC to 57.6k baud. Six diagnostic LED indicators are provided (see Figure 1) for in s tal l a t ion guid a nce and system trou b leshoot i ng. The RS-232 interface sup p orts Request To Send, Clear T o Send, Data Set Ready, Re c eived Line Signal Detect, and Data Ter m i n al Ready.A convenient null modem switch is pro v ided for the data lines. Also, a line termination switch connects a line termination resistor and line bias re s is t ors to the RS485 receive lines. The RS485 interface supports Request To Send and Clear To Send on separate wire pairs. The LDM485 may be used to convert two sets of send and receive channels by using RTS and CTS circuits as the second data channels. Data rates are thesame. The units use 12 Vac from a wall-mounted transformer to screw terminals 1 and 2 on the RS485 con n ec t or. Al t er n ate l y, they can use ±12 Vdc to pins 9 (+) and 10 (–) of the RS232 connector.The LDM485 conforms to EIA RS232 and RS485 specifications. Data T er m i n al Ready must be asserted by the host RS232 port before the LDM485 can transmit data. When Data Ter m i n al Ready is not as s erted, all outputs of the LDM485 are high impedance, allowing up to 64 LDM485 units to be mul t idrop p ed on a common com mu n i c a t ions cable. See Figures 1 and 3 for details.Request To Send and Clear T o Send are carried through the RS485 port as two separate wire pairs. These may be used for full duplex flow control.Data Terminal Ready, DTR, must be asserted before the LDM485 can trans m it data. This is normally done by the host computer. For situations where the host equipment does not have the capability of supplying a DTR signal, RLSD may be used to automatically assert DTR. On the RS232 connector P1 of each LDM485, simply connect RLSD pin 8 to DTR pin 20.

Observe operating instructions and affix close within sight of the battery! Work on batteries only under instructions of skilled personel! Smoking prohibited! Do not expose battery to open fame, glowing fire or sparks as explosion and fire hazard exists! When working on batteries wear protective glasses and clothing! Explosion and fire hazard! Avoid short circuits! Caution! Metal parts of the battery cells are always live, therefore do not place items or tools on the battery!Electrolyte is strongly corrosive! Monoblock batteries / cells are very heavy! Ensure secure installation! Only use suitable transport equipment! Dangerous voltage! Acid splashes in the eyes or on the skin must be washed out or off with plenty of water. Then see a doctor immediately. Acid on clothing should be washed out with water! Safety requirements according to EN 50272-31. Commissioninga) Filled and charged batteriesBefore commissioning all blocks must be inspected for mechanical damage, cells must be connected with the correct polarity and connectors firmly seated. The following torque apply for M10 screw connectors is:20 ± 1 Nm If necessary the terminal covers must be put on. Check the electroiyte level in all cells. If necessary top up to maximum level with purified water as under DIN 43530 Part 4. Before putting the battery in operation, plastic transport vent caps must be removed and replaced with ceramic cell plugs. With charger off and loads isolated connect battery to the direct current power supplies maintaining correct polarity (positive terminal to positive post). Switch on the charger and charge as under section 2.2.b) Dry charged (DC) batteries Instructions for the initial charging of a dry charged stationary OPzS and SOLAR (TOPzS) batteries: - Unscrew the sealed vent plugs and fill the cells with pure dilute sulphuric acid, specific gravity 1,230 0,01kg/1 read at 20 (68 F), up to about 25 mm below top of lid for SPgBG multi-block hard rubber containers and 50 mm below of lid for OPzS translucent containers or max level marked on the label. The temperature of the filling acid should be between 10°C and 25°C (50 - 77 F). - Insert the original plastic vent plug with Removed sealing foil on the top or place the special ceramic ventplug. - Start charging for not less than 2and not more than 12 hours elapsed after the last cell has been filled with the acid. - Apply the 0,5 x 110(5A/100Ah)current. - Charge for 8 hours and then keepthe battery on open circuit for 1-2 hours. - Continue the charging for a fewhours, until the battery is fullycharged, i.e. until constant voltage and constant specific gravity have been reached. The specific gravity of the acid in a fully charged celi is 1,240 0,01 kg/I read at 20°C (68 F), If during the charging thetemperature of the acid exceeds 55°C (131 F) reduce the charging current by 50%. - 0,5 h after charging discharge thebattery at 10 hour rate of current until the cell voltage drops toaverage value 1.80 Volts. Allowable minimum voltage of a single cell is 1,70V.- Recharge the battery according tothe operating instructions 2.2. - 24 hours after recharging adjustelectrolyte level to the “max” mark on the label.Activation and test results must be kept as part of batterydocumentation. Non-compliance with this request renders the warranty null and void.2. OperationFor the operation of stationary battery, installations EN 50272-2 apply2.1 DischargingNever allow the final discharge voltage of the battery to drop below that assigned for the discharge current. Chargeimmediately after discharge as well as partial discharge. Recommended DOD (Depth Of Discharge) for normal operating is up to 80% of CN.2.2 ChargingAll charging procedures with their limit values may be employed as stated below:DIN 41773 (lU characteristic) DIN 41774 (W characteristic) DIN 41776 (I characteristic).Depending on charger type and charging characteristic alternating currents flow through the battery superimposing onto the direct current. These alternating currents and the reaction of the loads lead to an additional warming of the battery and strain on the electrodes with possible resulting damage (see 2.5). Depending on the system at hand, charging may be carried out under the following modes:a) Stand-by parallel operation and floating operation.Here the load, direct current and battery are continuously connected in parallel. There by the charging voltage is at the same time the operating voltage of the system. With stand-by-parallel operation the direct current is at any time capable of supplying the maximum load current and the battery charging current. The battery only supplies current when the direct current source fails. The charge volt age should be set at 2,23 V +/-1% x number of cells measured at the battery’s terminals. To reduce therecharging time a charging stage can be applied in which the charging voltage is 2,35 to 2,4 V xnumber of cells (stand-by parallel operation with recharging stage).Automatic changeover to the charging voltage of 2,23 V+/- 1% x number of cells follows after few hours on the voltage 2,35-2,4 V x number of cells. With the floating operation the direct current source is not able to supply the maximum load current at all times. The load current intermit tentlysupersedes the nominal current of the direct current source. During this period the battery supplies power. It is not fully charged at all times. Therefore, depending on the load the chargevoltage must be set at 2.23 to 2.30 V x number of cells.b) Switch mode operationWhen charging the battery is separated from the load. Towards the end of the charging process the charge voltage of the battery is 2,6 - 2,75 V/cell. The charging process and parameters must be monitored (see Sections 2.4, 2.5 and 2.6).On reaching a fully charged state the charging process must be stopped or switched to float charge as under Section 2.3.OPERATING INSTRUCTIONS for stationary vented lead-acid OPzS SOLAR batteriesc) Battery operation (charge/discharge operation)Only the battery supplies the load. Hereby the charge voltage of the battery towards the end of the charging process is 2,6-2,75 V/cell. The charging process and parameters must be monitored (see Sections 2.4, 2.5 and 2.6). When reaching a fully charged state the charging process must be switched off. The battery can be switched to the load as necessary.2.3 Maintaining the full charge(float charging)Devices complying with the stipulations under DIN 41773 (lU characteristic) must be used. They are to be set so that the average cell voltage is 2,23V +/- 1% (2,25 V +/- 1% for UPS) cell at 20°C and the electrolyte density does not decrease over a protracted period(otherwise see 2.8).2.4 Equalizing chargeEqualizing charges are required after exhaustive discharges and after inadequate charges; they can be carried out as follows:- Up to 72 hours at constant voltage ofmax. 2.4 V/ celI,- With the I or W characteristic as under 2.6. If during equalizingcharging permitted load voltagesare exceeded, appropriatemeasures must be taken, e. g.disconnection of the load. Ifexceeding the maximumtemperature of 55°C the chargingmust either be stopped, proceedwith reduced current, or be switchedto float charge to allow thetemperature to drop. The equalizingcharge is completed when theelectrolyte densities no longerincreases within a period of 2 hours.2.5 Alternating currents with periodic deviationsOn recharging up to 2,4 V/cell as under operation modes a) to c) the actual value of the alternating current is occasionally permitted to reach max. 20 A per 100 Ah nominal capacity. Above 2,4 V/cells 10 A per 100 Ah nominal capacity may not be exceeded. In a fully charged state with a charge voltage of 2,23 to 2,30 V/cell the actual value of the alternating current must not exceed 5 A per 100 Ah nominal capacity.2.6 Charging currentsThe charging currents are not limited up to 2,4 V/ celI. When exceeding the charging voltage of 2,4 V/cell, greater water decomposition occurs. The charging currents per 100 Ah nominal capacity shown in Table 1 must not be exceeded.Charging procedure CellmodelCellvoltageI-charact. 5,0 A 2,6 -2,75W-charact. 7,0 A3,5 A at 2,4 V at 2,65V2.7 TemperatureThe recommended operatingtemperature for Lead-acid batteries is10°C to 30°C. The technical data applyfor the nominal temperature 20°C. Theideal operating temperature is 20 +/- 5°C.Higher temperatures shorten the servicelife. Lower temperatures reduce theavailable capacity. The maximumtemperature of 55°C must not beexceeded.2.8 Temperature-related chargevoltageA temperature-related adjustment of thecharge voltage within the operatingtemperature of 15°C to 25°C is notnecessary. Should the temperaturerange be lower than 15°C and/or higherthan 25°C a temperature relatedadjustment of the charge voltage shouldbe made. The temperature correctionfactor is (-0.004 V/Cell per °K).Should the temperature constantly riseabove 40°C then the factor is (-0.003V/Celi per °K).2.9 ElectrolyteThe electrolyte is diluted sulphuric acid.The nominal electrolyte density is basedon 20°C and the nominal electrolyte levelwhen fully charged with maximumdeviation +/ - 0.01 kg/I. Highertemperatures reduce the electrolytedensity; lower temperatures increase theelectrolyte density. The associatedcorrection factor is 0.0007 kg/I per °K.Example: electrolyte density of 1.23 kg/Iat 35°C corresponds to a density of 1.24kg/I at 20°C or electrolyte density of 1.25kg/I at 5°C corresponds to a density of1.24 kg/I at 20°C.3. Battery maintenance and controlThe electrolyte level must be checkedregularly. If it dropped to the lowestelectrolyte level mark, purified watermust be added as under DIN 43530 Part4, maximum conductivity 30 µS/cm. Toavoid leakage currents keep the batteryclean and dry (especially inter cellconnections). Plastic batterycomponents, in particular the vent caps,must only be cleaned with water thatcontains no additives. At least every 6months the following must bemeasured and recorded:- Battery voltage- Voltage of a few selectedcells/mono block batteries- Electrolyte density of a few selectedcells/mono block batteries- Electrolyte temperature of a fewselected cells/mono block batteries.The following must be measured andrecorded annually:- Voltage of all cells/mono blockbatteries- Electrolyte density of all cells/monoblock batteries- Electrolyte temperature of a fewselected cells/mono block batteries- Should the float charge voltage inone celi deviate more than + 0.1 Vor - 0.05 V from the average value(see 2.3), equalizing chargingshould be done (see 2.4.). Annualvisual checks:- on bolted connectors (check thatunsecured bolt connectors arefirmly seated)- on battery installation orarrangement- on ventilation of battery room.4. TestsTests must be performed on fully chargedbatteries according to EN 60896-1.ln addition, special test instructionssuch as EN 50272-2 must be observed.5. FaultsShould faults be detected in the batteryor the charging device, customerservices should be called in immediately.Measurement records under Section 3are necessary for fast fault detection andremoval.6. Storage and taking out of operationShould cells/batteries be stored or takenout of operation for a longer period oftime, they must be stored fully charged ina dry, frost-free room with max.temperature of 25°C. Direct sunlight orother heat sources mustbe avoided. To avoid damage thefollowing charging methods can bechosen:a. Equalizing charges on a quarterlybasis as under Section 2.4. In average,ambient temperatures of more than 30°Cmonthly equalizing charges may benecessary.b. Float charging as under Section2.3.above.7. TransportBatteries, wet, filled with acid requiretransport under demands of EuropeanAgreement concerning the internationalcarriage of dangerous goods (ADR andRID). ADR special provision No. 598:New batteries are not subject to therequirements of ADR, when:- they are secured in such a way thatthey can not slip, fall or bedamaged;- they are provided with carryingdevices, unless they are suitablystacked, e.g. on pallets;- there are no dangerous traces ofalkalis or acids on the outside;- they are protected against shortcircuits.8.

飞机的各种速度

飞机的各种速度

V Speeds DefinedV - SPEEDS DEFINEDThis information is based on data provided by Kenny Stone (DC3-603), George Leach (DC3-754), a search of the Internet and FS2000 manuals. Numbers are usually stated, as in "Vee One" for V1. Lower case letters, many times shown as a subscript font, are referred to as "sub" as in "Vee sub a" for Va.V1 - Takeoff Decision Speed - maximum speed during takeoff that will allow the pilot to stop on the remaining runway in case of a rejected (aborted) takeoff.V2 - Takeoff Safety Speed - Speed at 35 feet AGL assuming engine failure at V1.Va - Maneuvering Speed - Sometimes referred to as the "speed for maximum control deflection" or the "rough air airspeed." When flying above this speed it is unwise to make full, abrupt application of the primary flight controls and gust-induced loads can exceed the structural design limit.Vb - Turbulence Penetration Speed - design speed for maximum gust intensity. Developed by the designer as a recommended turbulence penetration speed for an aircraft in severe turbulenceVbg - Best Power-off Glide Speed - the CAS that provides minimum drag thus a best glide ratio, providing the greatest flight distance available from the potential energy of height.Vbe - Best Endurance Speed - the CAS that gives the greatest airborne time for fuel aboard, i.e., the least fuel consumption per hour.Vbr - Best Range Speed - the speed that provides a lift/drag ratio that provides minimum drag and minimum power required and consequently greatest air distance for fuel on board.Vc - Cruise Speed - the design cruising speed or the optimum cruise speed. Vd - Design Dive Speed - Is usually 1.4 times Vno.Vg - Best Glide Speed - The speed that will afford the best range for a given altitude without engine power.Vh - Maximum Level Flight Indicated Speed (CAS) - the maximum using continuous engine power.Vfe - Maximum Flap Extended Speed - The maximum speed for flight with flaps extended. Indicated by the top end of the White Arc on the Airspeed Indicator. Higher speeds, with flaps down, may result in damage to the flaps or to the extension mechanismVle - Maximum Landing Gear Extended Speed - For planes with retractable landing gear, the maximum speed at which the gear can remain extended without damage to gear doors.Vlo - Maximum Landing Gear Operating Speed - For planes with retractable landing gear, the maximum speed at which the landing gear system can be operated (extend or retract).Vmc - Minimum Control Speed - This is a speed the manufacturer determines based on eight factors specified by the FAA. In general, with gear down and flaps in takeoff position, it is the minimum speed where the pilot can maintain control of the aircraft with the critical engine inoperative.Vmd - Minimum Descent Speed - The speed that results in the lowest rate of sink in a power-off glide, providing the longest duration of flight from the potential energy of height.Vmo - Maximum Operating Speed - The speed that must not be exceeded in any flight regime.Vmu - Minimum Unstick Speed - An indicated speed (CAS) used intake-off conditions where it is advisable to lift off at the lowest possible airspeed to get the tires off the surface, e.g. soft field or wet grass and safely fly in ground effect until Vtoss is attained.Vne - Never Exceed Speed - The speed, which must not be exceeded in smooth air. The Red Line at the top end of the Airspeed Indicator's Yellow Arc. Vne is set at 90% of Vd to provide a "flutter" margin.Vno - Maximum Structural Cruise Speed - When cruising at, and below, Vno the aircraft should not be damaged by a 30 feet/second vertical gust. It is indicated by the top end of the Airspeed Indicator's Green Arc. Smooth air only for speeds in the Yellow Arc.Vr - Rotation Speed - The speed at which the pilot raises the nose up for takeoff.Vref - Final Approach - A safe speed for final approach and it should be 1.3 times VsoVs - Stalling Speed - The minimum steady flight speed obtained in a specific configuration (clean) indicated by the bottom end of the Green Arc on the Airspeed Indicator.Vs1 - Stalling Speed - Same as Vs, except for a specific configuration.Vso - Stalling Speed Landing - The minimum steady flight speed in the landing configuration. Bottom of the White Arc on the Airspeed Indicator. Vtoss - Minimum Takeoff Safety Speed - An indicated speed (CAS) chosen to ensure that adequate control will still exist during initial climb after lift off under conditions of turbulence - or even engine failure. After lift off the aircraft should not be allowed to climb away until Vtoss is attained.Vx - Best Angle Of Climb Speed - The speed that will produce the greatest amount of height over the shortest ground distance using maximum thrust available.Vxse - Best Angle Of Climb Speed, Single Engine - The same as Vx based on a single engine.Vy - Best Rate Of Climb Speed - The speed that will produce the most height in the shortest time using maximum power.Vyse - Best Rate Of Climb Speed, Single Engine - The same as Vy based on a single engine.。

故选C。

2.如图所示,竖直放置的肥皂薄膜受到重力作用而形成上薄下厚的薄膜,从膜左侧面水平射入红光,在左侧面观察到干涉条纹,则下列说法正确的是()A.干涉条纹是由薄膜左右两个面的反射光叠加形成的B.干涉条纹是红黑相间的竖直条纹C.入射光如果换成紫光,相邻亮条纹间距变大D.薄膜上不同颜色的光的条纹的明暗位置相同A解析:AA.干涉条纹是由薄膜左右两个面的反射光叠加形成的,A正确;B.干涉条纹是红黑相间的水平条纹,B错误;CD.光波的干涉条纹的间距公式Δlxd λ=入射光如果换成紫光则波长变短,相邻亮条纹间距变小,而且由于不同光的干涉条纹的间距不同,故不同颜色的光的条纹的明暗位置不相同,故CD错误;故选A。

3.一束由红光和紫光组成的复色光斜射到水平放置的平行矩形玻璃砖的上表面上的O 点,如图所示,入射光线与法线的夹角为i。

系统化护理干预对呼吸内科重症患者的护理效果观察

系统化护理干预对呼吸内科重症患者的护理效果观察发布时间:2021-11-17T00:55:36.849Z 来源:《健康世界》2021年19期作者:李凤朱蓉[导读] 目的:对呼吸内科重症患者实行系统化护理,探究其所产生的实际效果李凤朱蓉成都医学院第三附属医院.成都市郫都区人民医院611730摘要:目的:对呼吸内科重症患者实行系统化护理,探究其所产生的实际效果。

方法:以2020年4月-2021年4月为时间段,从我院病例信息管理系统中选取出58例呼吸内科中的重症患者,将其纳入实验研究范围,所有患者对半划分,其中29例归为A组(观察组),另外29例归为B组(对照组)。

对B组患者采用一般护理,对A组患者采用系统化护理,后就两组患者的预后效果及患者预前预后的各项指标进行对比。

结果:从两组患者的预后效果来看,A组患者的预后效果更佳,其护理总有效率极高,从两组患者的各项指标来看,A组患者均优于B 组,上述各方面两组间均存在显著差异(P<0.05)。

结论:对重症呼吸道疾病患者实行系统化护理所体现出的效果极好,不仅能够使患者的病情发展得到有效抑制,同时还能够促使患者康复的速度加快,值得大力推广。

关键词:系统化护理;呼吸内科;重症患者;实际效果呼吸系统作为气体交换的场所,与外界相通,因此外界空气中的病原体等均极易进入呼吸道从而引发感染,致使人体患病。

通常情况下,呼吸道疾病患者的症状主要体现为呼吸困难、精神不振等,更有甚者还会体现出呼吸衰竭等严重现象。

临床上单靠治疗无法促使患者的病情好转,只能在一定程度上缓解患者的症状,对此需辅以科学合理的护理措施,不仅可以巩固治疗效果,同时还能够抑制患者病情的发展,促使患者早日康复[1]。

现就系统化护理对患有此类疾病的患者所产生的实际临床效果进行分析探讨,具体报道为以下内容。

1.资料与方法1.1一般资料以2020年4月-2021年4月为时间段,从我院病例信息管理系统中筛选出58例患有呼吸道疾病的重症患者纳入实验研究范围,将其对半划分为两组,其29例作为A组(观察组),另外29例作为B组(对照组)。

南京06年高考录取率75.21% 65人考上北
大清华
9月,随着中考、高考招生相继落幕,义务教育免杂费后的第一个新学期开学,昨天,市政府召开新闻发布会,总结了今年我市义务教育免收杂费和中等学校、高校招生录取情况。

今年,南京52万义务教育阶段学生秋季开学时全部享受政府免收杂费。

其中既包括本市户口的学生,也包括符合政策的外来务工人员子女;既涵盖了公办学校,也覆盖了民办学校。

免杂费范围之广在江苏省列于首位。

此外,2万多困难家庭学生获得助学金、助学券等形式的教育资助。

对他们而言,基本实现了义务教育“全免费”。

今年南京中考、高考招生录取情况也十分喜人。

初中升高中录取率继续稳居95%以上,70%的学生可以进入优质高中。

高考录取率超省均5个百分点,本科录取净增2000多人,高考成绩再度大幅攀升。

在昨天的新闻发布会上,南京市教育局财务处处长张明对有关情况,做了详细的介绍说明。

据了解,今年秋季开学时,南京义务教育实现了减免“提速”和助困“扩容”——52万义务教育阶段学生秋季开学普惠性享受政府免收杂费,2万多困难家庭学生义务教育基本实
现“全免费”。

今年全市累计新增投入6400万元,比原计划提前四年半,全面实行义务教育阶段学生免收杂费政策,惠及城乡521700名学生,每个学生全年可免交杂费170元-310元。

据介绍,凡符合省市规定,在南京接受义务教育的外来务工人员子女,无论其就读公办学校或者民办学校,也都同步享受减免。

在全省,只有南京将减免的范围惠及民办学校和外来务工人员子女。

此外,全市600多名特困职工家庭子女和800名就读中等职业学校的困难家庭学生,今年也首次获得减免和资助。

记者了解到,截至目前,南京已构建起多层次、多路径的“绿色助学通道”,共为67000多人次的困难家庭学生,减免学习费用累计达1500多万元,确保全市义务教育阶段适龄学生,不会因为贫困而失学。

据南京市招生办公室主任刘安康介绍,今年南京高考本、专科录取人数均比去年有所增加,高考成绩再创历史新高,录取率达%,高于省均个百分点。

今年我市报名参加高考人数为35333人,实际被各类高校录取26573人,本、专科录取人数分别为13834人和12739人,录取人数比去年增加2343人。

其中本科录取人数比去年增加2092人,本科录取率高于省均个百分点。

今年被提前录取到国内外知名大学的学生为483人,比去年净增260多人,录取人数比去年实现翻番,占全省60%以上。

其中,被北大、清华两所国内顶尖高校录取的学生共有65人。

被清华录取的保送生有27人,被北大录取的保送生有16人。

还有22人通过普通高考被清华、北大录取。

除了南京外国语学校、南师大附中、金陵中学、南京市一中4所老牌名校,其他几所学校也培养出了能考入北大、清华的学生,如宁海中学有3人被清华录取,6中有1人被清华录取,南师附中江宁分校有3人被清华录取,1人被北大录取,六合高级中学有2人被北大录取。

南京今年不仅一大批重点中学高考成绩喜传捷报,市直属的三所名校分校也势如“黑马”。

南外仙林分校、南师附中江宁分校、金陵中学河西分校今年本科达线率均超过50%。

此外,高淳、溧水等县本科达线人数均增长50%以上,昔日“洼地”今日明显崛起,城乡教育均衡的推进大见成效。

南京市招办透露,今年南京共有170多名学生被英国剑桥大学、美国宾夕法尼亚大学、美国格林奈尔学院、加拿大多伦多大学等国外名校录取。

今年1月份,仅被多伦多大学录取的南京学生就已有72名。

其中包括南外本部43人、南外仙林分校6人、南外中加班10人,其他学校13人。

加上英国剑桥等国外知名院校
录取的南京学生,到目前共有170多名。

多伦多大学的入学考试所涉及的内容五花八门。

以笔试为例,学生须在45分钟时间内完成一篇命题作文,从供学生选择的5个作文题可以看出,除了需要相当的英文水平外,还考察了学生课本以外的知识和发散性思维,比如“介绍一下你心目中南京最吸引人的景点”、“如果有机会与一个历史人物会面,你会选择谁?为什么?”
前来南京主持考试的多伦多大学招生办公室主任当·麦克米伦先生说,他发现中国的学生基础知识非常扎实。

参加考试的南外学生郭亨说,面试时考官很注重他简历上参加课外活动的情况,提的全是课本以外的多元化问题,这使他得以充分发挥优势。

他的老师透露,王天晓初中三年在数理化、计算机等竞赛中共取得了
50多个奖项,确实是个非常优秀的学生。
