The board also features oneMicrel, Inc. January 11, 2011MII connector for the Switch MII interface. It is to facilitate connection from the switch to either the external CPU or the external PHY.Figure 1: KSZ8873MLL/FLL/RLL Evaluation Board Block DiagramThe KSZ8873MLL/FLL/RLL evaluation board is easy to use. There are programmable LED indicators for link and activity on the PHY ports and a power LED. A manual reset button allows the user to reset the board without removing the power plug. The 5V power on the board can be supplied by a standard 5VDC power supply (close pin 1-2 of JP400 jumper) or by the USB cable (close pin 2-3 of JP400 jumper) which is used to access the registers in SPI mode. A standard 5VDC power supply is included so that the user can supply power from any 110 Volt AC wall or bench socket. Before to start to use the evaluation board, make sure the power connectors JP403, JP404, JP405 and JP31 are connected, and close pin 1-2 of J14.4.1 Strap In ModeStrap in configuration mode is the quickest and easiest way to get started. In this mode, the KSZ8873MLL/FLL/RLL acts as a standalone 3-port switch. Simply set the board’s configuration jumpers to the desired settings and apply power to the board. The configuration can be changed while power is applied to the board by changing the jumper settings and pressing the convenient manual reset button for the new settings to take effect. Note that even if no external strap in values are set, internal pull up and pull down resistors will set the KSZ8873MLL/FLL/RLL default configuration. Section 4.1.1 covers each jumper on the board and describes its function. To start in strap in configuration mode, make sure that the USB cable is unplugged, JP34, JP35, JP3and JP9 are connected, JP21, JP25 have jumpers fitted between pins 2 to 3.Micrel, Inc.

3M Versaflo S-Series 呼吸器头罩和头巾说明书
3M™ Versaflo™ S-Series Hoods and Headcovers3M™ Versaflo™ S-Series Hoodsand Headcovers for Powered andSupplied Air Respirators/Versaflo22Many wearers of half and full facepiece respirators are taking a second look at powered and supplied air respirators for reasons that go beyond compliance.All-Day ComfortNew 3M™ Versaflo™ S-Series Hoods and Headcovers have beendesigned to provide users with the optimal level of comfort.Easily adjustable suspensions (most models) and soft comfortpads help provide excellent fit, stability and tracking. Comfortsuspension hoods and headcovers feature wide faceseals withsoft elastic for improved comfort and reduced air flow noise. Thepremium reusable suspension allows wearers to modify the airflowdistribution inside the hood to suit personal comfort needs. All ofthese improvements combine to help workers stay more comfortablethroughout the day.VersatilityAs a part of Versaflo respirator systems, S-Series hoods andheadcovers can be used in dozens of different Powered Air PurifyingRespirator and Supplied Air Respirator combinations.Excellent AirflowS-Series hoods and headcovers direct a comfortable stream of airinto the headgear. The moving airflow may make hot environmentsmore tolerable while reducing visor fogging. When used with anapproved 3M™ Supplied Air Regulator, the compressed air can bemade cooler or warmer by up to 50°F (28°C) for additional comfort.High Performance–APF3M has conducted research to document an Assigned ProtectionFactor (APF) of 1000 for the S-Series hoods when used as part of aNIOSH-approved powered or supplied air respirator system. An APFof 1000 is the highest level allowed under the Occupational Safetyand Health Administration (OSHA) Respiratory Protection Standard(29 CFR 1910.134) for this class of respirator. S-Series headcovershave an APF of 25, making them suitable for a wide range ofapplications and working environments.Fast AssemblyAll S-Series compatible breathing tubes feature the innovative 3M™Quick Release Swivel (QRS) connection. Simply push the QRS end ofthe breathing tube into the air inlet of the headgear until it snaps intoplace. The breathing tube can be quickly removed with only one handby squeezing the breathing tube clips.Simple MaintenanceChoose the ready-to-use integrated suspension models forapplications where assembly would be too time-consuming orimpractical. Or select the premium reusable suspension hoods forquick, highly cost-effective replacement of outer fabrics.3M™ Versaflo™3M ™Versaflo ™4Integrated Suspension Hoods and HeadcoversAvailable with two different suspensions, comfort and fabric,integrated suspension hoods and headcovers offer the advantage of being fully assembled and ready to use straight out of the box. They can be suitable for applications that require frequent replacement of the entire headgear assembly, such as pharmaceuticalmanufacturing, or in situations where there is less soiling of the outer fabric. Integrated suspension headgear is available in two sizes to comfortably fit more wearers: S/M and M/L.CoMFoRT SuSPENSIoN MoDELSIntegrated suspension models S-133, S-133B and S-533 also feature a wide faceseal with soft elastic for improved comfort and reduced noise. The new airflow distribution minimizes the potential for air whistling past the wearer’s ears, allowing for better worker communication and improved comfort. A new exhalation panel vents the headtop without the traditional vent hole pattern or exhalation valve.FABRIC SuSPENSIoN MoDELSEconomy suspension models S-103 and S-403 provide a lower cost alternative to value-conscious customers while still offering comfort and protection.3M ™ Versaflo ™ Economy Headcover S-103Head and face coverage.

The new design permits significantly faster user assembly of the entire headtop.The suspension’s new rigid ducting provides a consistent air path. An externally-adjustable airflow control allows wearers to modify the airflow distribution to suit personal comfort needs. While wearing, the airflow may be directed primarily to the front visor or split to provide more airflow to the top of the head.The suspension has independent adjustments for the crown and head circumference, allowing a comfortable, custom fit for a wide range of head sizes. An optional size-reducing comfort pad is provided to further extend the range of compatible head sizes.Opened ValveClosed ValveThe external cover letswearers modify the location ofthe airflow.3M Automotive Aftermarket Division (AAD) Product Numbersare found in blue type on selected products.3M ™ Versaflo ™ HoodNew Breathing TubesAll S-Series compatible breathing tubes feature the innovative 3M™ Quick Release Swivel (QRS) connection. The QRS connects quickly to the headgear and swivels to minimize loops and kinks in the breathing tube.3M™ Versaflo™Breathing Tube,Small/MediumApprox. 28", features steelcore coils for durability.To improve comfort andreduce the potential tocatch on the wearer’ssurroundings, BT-20 tubesare available in two sizes.373093M™ Versaflo™Breathing Tube,Medium/LargeApprox. 38", featuressteel core coils fordurability.

山药中含有丰富的多糖、黄酮、过氧化氢酶、尿囊素、植酸、山药碱等成分因子［１－３］，还含有多种维持人体生命活动必要的无机元素、金属元素和微量元素，可以提高机体免疫能力。
除此之外，山药还具备显著降低血糖浓度及血脂浓度的功效，可以调理肠胃功能，增强营养的摄入吸收，起到保健作用［４］。
鲜切山药既保留了山药的营养成分，同时又具备鲜切果蔬方便快捷、可完全食用的特点，因而成为目前山药最合适的加工方式之一。
如何增强鲜切山药的抗氧化性能，保证品质质量，延长其商品的货架期，是鲜切山药加工存放与交易流通的关键，这也使得鲜切山药的保鲜问题成为我国山药行业的重点研究方向［５－７］。
