光开关主要性能指标及各类光开关比较
光开关主要性能指标及各类光开关比较【内容摘要】:前面已经讲到光开关是光交换的关键器件,其主要任务是切换光路,是全光网中全光交换的核心器件。
本文讲述如何评价光开关质量优劣的主要性能参数并对现有光开关作一定的比较,希望帮助读者对光开关有一个更好的理解。
【关键字】:光开关 性能参数 质量比较【正文】:一、 光开关的主要性能参数1、开关时间:开关时间是光开关的主要指标。
不同的应用场合,对光开关的开关时间要求不同。
如下图是实现一些特定功能对光开关的时间需求:2、损耗:光信号通过光开关时,将伴随着能量损耗。
依据功率预算设计网络时,光开关及其级联损耗对网络性能的影响很大。
损耗和干扰将影响到功率预算。
光开关损耗产生的原因主要有两个:光纤和光开关端口耦合时的损耗和光开关自身材料对光信号产生的损耗。
在这里主要强调插入损耗。
插入损耗:光信号通过连接器之后,其输出光功率相对输入光功率的比率的分贝数。
其中Pin 为进入开关的光功率,Pout 为出开关的光功率。
一个好的光开关要求有较低的插入损耗。
10lg (dB)out inP IL P =-3、光路回波损耗:反射损耗,光纤连接处,后向反射光相对输入光的比率的分贝数:其中Pt 表示回射波的功率,Pl 表示入射波的功率。
光路回波损耗是源于光开关与电缆链路中由于阻抗不匹配而产生反射的而造成的损耗。
4、交换矩阵的大小:光开关交换矩阵的大小反映了光开关的交换能力。
光开关处于网络不同位置,对其交换矩阵大小要求也不同。
对于大交换容量的光开关,可以通过较多的小光开关叠加而成。
HP/Agilent Bubble 开关阵列5、交换速度:交换速度是衡量光开关性能的重要指标。
交换速度有两个重要的量级,当从一个端口到另一个端口的交换时间达到几个ms 时,对因故障而重新选择路由的时间已经够了。
如SDH/SONET 来说,因故障而重新选路时,50ms 的交换时间几乎可以使上层感觉不到。
当交换时间到达ns 量级时,可以支持光互联网的分组交换。

色谱柱常用填料
保护柱填料一般与分析柱填料相同。
Hypersil 填料Hypersil填料是基于粒度为3um、5um和10um,孔径为120A的硅胶为基质的HPLC 填料其生产过程的质量控制标准非常严格全世界数千个实验室使用Hypersil色谱柱已长达20多年很多应用实例可以从多种文献及著名杂志上查到。
大量的试验测试已经证实Hypersil ODS2 填料是替代Waters Spherisorb ODS2的最佳填料无论是在酸性还是碱性样品的分析上选择性与峰型几乎与其保持一致。
|Hypersil BDS 填料尽管常规填料色谱柱具有优异的选择性和较长的色谱柱寿命且对于简单的两元流动相如甲醇/水当样品为酸性中性和弱碱性化合物时均可获得较佳的峰不对称度但当分析药物等样品中的强极性含氮的化合物时样品峰型就极差拖尾严重并导致定量分析精度下降时常会出现一些小峰埋没于前一拖尾峰的尾巴中造成该现象的原因是固定相上尚有残余的硅羟基尽管很多厂家对硅胶表面作了第二次反应即所谓的封尾以减小残余硅羟基的作用但往往都不能完全消除残余的硅羟基的影响Hypersil公司开发的将残余的硅羟基降至极限的Hypersil BDS (Base Deactived Silica碱钝化硅胶)系列产品并用现代衍生反应技术生产出特别适用于碱性化合物的真正均一反相填料。
Hypersil BDS填料的特征*对碱性化合物有更好的峰型*更长的柱寿命*更好的稳定性*同碱性化合物一样酸性和中性化合物也有非常优异的峰型真正的通用柱填料。
尽管常规填料色谱柱具有优异的选择性和较长的色谱柱寿命。
且对于简单的两元流动相(如甲醇/水),当样品为酸性、中性和弱碱性化合物时均可获得较佳的峰不对称度。
但当分析药物等样品中的强极性含氮的化合物时,样品峰型就极查,拖尾严重,并导致定量分析精度下降,时常会出现一些小峰埋没于前一拖尾峰的尾巴中,造成该现象的原因是固定相上尚有残余的硅羟基。
尽管很多厂家对硅胶表面作了第二次反应,即所谓的“封尾”,以减小残余硅羟基的作用,但往往都不能完全消除残余的硅羟基的影响。

Introduction of Akzo Nobel Metal AlkylsAkzo Nobel Polymer Chemicals is a major, global supplier of metal alkyls. Using technology licensed by Nobel laureate Karl Ziegler, large-scale production of aluminum alkyls was pioneered by Akzo Nobel in 1959. The original manufacturing site in Deer Park, TX was formerly known as Texas Alkyls, Inc., but has been wholly owned by Akzo Nobel since 1992. Today, Akzo Nobel supplies more than 50 developmental and commercial products encompassing metal alkyl derivatives of aluminum, magnesium, boron and zinc.Recognizing increasing worldwide requirements, Akzo Nobel expanded capacity in 1996 with the construction of a major metal alkyl manufacturing facility near Rotterdam, The Netherlands. From the Deer Park and Rotterdam sites, as well as from smaller facilities in Tianjin, China and Paulinia, Brazil, Akzo Nobel supplies a broad range of metal alkyls to customers on six continents. These customers are primarily manufacturers of polymers, such as polyethylene, polypropylene, and synthetic rubber, produced via Ziegler-Natta polymerization.As markets for polyolefins and elastomers grew, so too did Akzo Nobel, expanding scale of manufacture and diversifying product line to accommodate emerging technologies:• In 1971, Akzo Nobel was the first supplier to offer ultrapure trimethygallium (TMG*) for use in making compound semiconductors. In addition to TMG, Akzo Nobel now offers a range of high purity metal organics (HPMO). Such products, previously known as semiconductor grade metal organics (SGMO), have metallic purities in excess of 99.99%. In 2000, HPMO became a separate Akzo Nobel Polymer Chemicals business unit (for more information see ). Facilities for HPMO production were expanded in 1987, 1993 and 2002.• In 1975, Akzo Nobel became the first commercial producer of hydrocarbon-soluble dialkylmagnesium compounds for use in polyethylene manufacture. Akzo Nobel is now the global leader in manufacture of magnesium alkyls for the polyolefins industry.• In 1998, Akzo Nobel completed a major expansion in Deer Park to produce trimethylaluminum (TMAL). TMAL is required for the production of a variety of methylaluminoxanes used as activators (co-catalysts) for single-site catalysts (SSC). It is also a crucial raw material for HPMO products.Akzo Nobel is an industry leader in metal alkyls safety and environmental know-how. Akzo Nobel is committed to the ACC Responsible Care®Code of Management Practices. The Deer Park site has achieved ISO 9001 certification for design, development and manufacture of metal alkyls. Deer Park has also received ISO 14001 certification for environmental standards. The Rotterdam, Paulinia and Tianjin sites are ISO 9002 and ISO 14001 certified. Additionally, Deer Park is an OSHA VPP Star site and both Rotterdam and Paulinia have achieved OHSAS 18001 certification.A. Analysis of Metal AlkylsAnalysis of metal alkyls requires the controlled hydrolysis of the compounds to their respective metal ions, halide ions and alkanes. Generalized equations for these reactions are shown below.R n AIX3-n + 3 H2O n RH + (3-n) HX + AI(OH)3where 1 ≤ n ≤ 3, and X = F, CI, Br, I, H or OR2Mg + 2 H2O Mg(OH)2 + 2 RHR2Zn + H2O ZnO + 2 RHDifferent methods have been advanced to achieve the analysis of metal alkyls.Procedures most suitable for quality control are simple and provide the necessary degree of accuracy and precision. Methods used to determine metal and halide content and hydrolysis gas composition are summarized in the following sections. From a single hydrolysis of a metal alkyl sample, the metal (aluminum, magnesium or zinc) and halogen (chloride and iodide) contents can be determined. By using a different hydrolysis technique, gaseous hydrolysis products consisting of alkanes and hydrogen can be determined.These combined analyses then can be used to derive the composition of the sample.Unlike aluminum, magnesium and zinc alkyls, alkylboranes may be analyzed directly by GC*, i.e., without hydrolysis. (See references contained in the TB entitled Properties of Alkylboranes from Akzo Nobel). Akzo Nobel determines purity of alkylboranes using GC and/or NMR spectroscopy.Akzo Nobel continues to explore the use of new and improved techniques for the analysis of metal alkyls to improve safety, accuracy and precision of analytical methods.Other techniques include:• Laser Raman (LR) Spectroscopy• X-Ray Fluorescence (XRF) Spectroscopy• Inductively Coupled Argon Plasma (ICP) SpectroscopyB. Titrimetric Analysis for Metal and Halogen Content1. Summary – The metal alkyl sample (0.150± 0.015g metal) is weighed and hydrolyzed under controlled conditions. Aluminum and zinc content in an aliquot of aqueous hydrolysis solution are determined by complexometric titration by addition of an excess amount of a standard solution of the disodium salt of ethylenediaminetetraacetic acid (EDTA) followed by back titration with standardized ZnSO4. Magnesium content is determined by direct EDTA titration. Weight percent of the metal of interest is calculated from the milliequivalents of metal in the aliquot and the weight of the sample hydrolyzed. Halogen content in a second aliquot of the hydrolysis solution is found by direct potentiometric titration with standard AgNO3. As in the metal determination, weight percent halogen is calculated from the milliequivalents of the halide in the aliquot and the weight of the sample hydrolyzed.2. Hydrolysis of the Samplea. Reagent and Equipment•Sulfuric acid (0.5N): ACS, reagent grade.•n-Heptane (high purity).•Sample delivery syringe assembly: 2-, 5- or 10-mL Cornwall syringe fitted with a Perfektum spring clip, Luerlok® stopcock and a 1” long, regular point, 20-gauge hypodermic needle. A 2-mL syringe with metal syringe holder is recommended for transferring concentrated alkyl samples.•Hydrolysis bottle: 350-mL minimum capacity with neck to fit a crown cap. Hydrolysis bottles used at Akzo Nobel are specially designed heavy-walled borosilicate bottles.•Crown cap: Long-skirted metal beverage cap with two 1/8” holes or four holes (two 1/8”and two 1/16”).•Rubber liner: Buna-N to serve as a seal between bottle cap and bottle.•Heated Shaker Bath: Maintained at 60± 5°C.•Analytical balance: One that will weigh accurately to 0.0001g and has a capacity of at least 150g.b. Procedure for Hydrolysis of Sample – Weigh a sample of metal alkyl in a sample delivery syringe assembly. Sample should contain 0.150g ± 0.015g of metal. Deliver the syringe contents cautiously to an evacuated hydrolysis bottle that contains 100 mL of 0.5N H2SO4 and about 35mL of n-heptane. Place the hydrolysis bottle with contents in the heated shaker bath for at least 15 minutes or until contents are completely digested. Remove the hydrolysis bottle and cool to room temperature. Alternatively, samples can be hydrolyzed by stirring on a hot plate for 15 minutes at 60 °C.3. Complexometric Determination of Aluminum or Zinc Contenta. Reagents and Equipment•Disodium salt of ethylenediaminetetraacetic acid (EDTA) (0.02N): ACS, reagent grade, standardized against pure aluminum.•trans-1,2-diaminocyclohexane tetraacetic acid monohydrate (CDTA) can be used as an alternate (to EDTA) complexing agent: ACS, reagent grade.•Zinc sulfate (0.02N): ACS, reagent grade, standardized against standard EDTA.•Sodium acetate buffer: ACS, reagent grade. Prepare a pH 5 buffer by dissolving 27.3g of sodium acetate in 60 mL of 1N HCI and dilute to one liter with demineralized water.•High strength sodium acetate buffer and xylenol orange indicator solution: Prepare a pH5.5 buffer by dissolving 1000g of sodium acetate and 40 mL of 1N HCI in 15 Ldemineralized water. The solution is diluted to 18 L total solution. Dissolve 0.25g xylenol orange in the buffer solution.•Sodium fluoride (0.8N): ACS, reagent grade.•Berzelius tall form beaker: 300-mL capacity.•Aliquot syringe assembly: 10-mL BD Cornwall syringe with metal Luerlok® and 1”regular point, 20-gauge hypodermic needle. The syringe is fitted with a metal holder which can be locked to deliver a constant volume. The syringe must be calibrated to deliver exactly 10.0 mL.•Titration can be done manually using an endpoint indicator change from yellow to peach (the sample is over-titrated at a scarlet endpoint). Autotitration (Brinkmann 682 Titroprocessor or equivalent) using a photoprobe colorimeter equipped with a 550 nm filter (or equivalent) can also be utilized for the analysis.b. Procedure for Titration and Calculation of Aluminum Content – Transfer a 10-mL aliquot of the hydrolyzed solution to a clean 300-mL Berzelius beaker. Use multiple aliquots for lower concentration of aluminum. Deliver the appropriate increment of EDTA to complex the aluminum leaving an excess of approximately 5-10 mL EDTA. Add 20 mL of sodium acetate buffer to beaker. Heat the beaker until it boils for no more than two minutes. Cool the beaker to room temperature in the water bath. (Boiling the sample is not required if CDTA is used to complex the metal.) Add 50 mL demineralized water and 80 mL high strength sodium acetate solution. Back titrate with standard zinc sulfate. Back titer should be between 4 and 8 mL.Note: Calculation of weight percent aluminum is based on a 10-mL aliquot from 100-mL aqueous hydrolysis solution. Multiple aliquots (20, 30-mL, etc.) require division by the number of 10-mL aliquots used.[(V EDTA x N ZnSO4)] x 26.982Weight % Aluminum = ––––––––––––––––––––––––––––––Weight of Sample Hydrolyzed (g)c. Procedure for Titration and Calculation of Zinc Content – Aluminum interferes with the zinc analysis at pH 5. To determine zinc in the presence of aluminum, 10 mL of 0.8N NaF solution is added to an aliquot of the hydrolyzed solution to mask the aluminum. The sample is then titrated for zinc content in a manner similar to that described for aluminum. If both metals are present, an additional aliquot without the masking agent must be titrated. The difference between the unmasked titer and the masked titer is due to the amount of aluminum present.Note: Calculation of weight percent zinc is based on a 10 mL aliquot from 100 mL aliquot of aqueous hydrolysis solution. Multiple aliquots (20, 30 mL, etc.) require division by the number of 10-mL aliquots used.[(V EDTA x N EDTA) - (V ZnSO4 x N ZnSO4)] x 65.38Weight % Zinc = ––––––––––––––––––––––––––––––Weight of Sample Hydrolyzed (g)4.

Prepare a 10-11 pH buffer solution by dissolving 65.5g NH4CI in 570 mL NH4OH (reagent grade, 28-30% assay as NH3). Dilute to one liter with demineralized water.•Berzelius tall form beaker: 300-mL capacity.•Titration can be done manually using an endpoint indicator change from violet to blue.Autotitration (Brinkmann 682 Titroprocessor or equivalent) using a photoprobe colorimeter equipped with a 660 nm filter (or equivalent) can also be utilized for the analysis.b. Procedure for Titration and Calculation of Magnesium Content – Deliver a 10-mL aliquot of the aqueous phase of the hydrolysis solution to a 300-mL Berzelius beaker. Add 8 mL 20% triethanolamine/Calmagite indicator solution and 30 mL of ammonium chloride/ammonium hydroxide solution. Titrate to a blue endpoint with standard EDTA.NOTE: Calculation of weight percent magnesium is based on a 10-mL aliquot from 100-mL aqueous hydrolysis solution.(V EDTA x N EDTA) x 24.31Weight % Magnesium = ––––––––––––––––––––––––––––––Weight of Sample Hydrolyzed (g)5. Potentiometric Determination of Chloride and Iodide Contenta. Reagents and Equipment•Silver nitrate (0.05N): ACS, reagent grade, standardized against 1.5M potassium chloride.•Titration is conducted manually using a pH meter (or automatically using a Brinkmann 686 Titroprocessor or equivalent).•Electrode: Combination silver billet and calomel reference porous plug type.•Berzelius tall form beaker: 300-mL capacity.b. Procedure for Titration of Halogen Content – Deliver a 10-mL aliquot of the aqueous hydrolysis solution to a 300-mL Berzelius beaker. Add 0.1g of potassium nitrate and dissolve by gentle swirling. (Do not use KNO3 with alkylaluminum iodide samples.) Initiate stirring mechanism and lower electrodes into the solution Titrate solution with standardized AgNO3 to respective potentiometric endpoint(s).NOTE: The calculation is based on a single 10-mL aliquot of the 100-mL hydrolysis solution.V AgNO3 x N AgNO3 x 126.90Weight % Iodine = ––––––––––––––––––––––––––––––Weight of Sample Hydrolyzed (g)V AgNO3 x N AgNO3 x 35.453Weight % Chlorine = ––––––––––––––––––––––––––––––Weight of Sample Hydrolyzed (g)C. Gas Chromatographic Analysis of Hydrolysis GasExcept for alkylboranes, direct GC analysis of metal alkyls is impractical due to the high reactivity of most metal alkyls. Consequently, the conventional method for analyzing alkyl group composition has been to hydrolyze small samples to generate volatile hydrocarbon gases and hydrogen as shown in equations 9 through 11. The procedure is useful for analyzing aluminum alkyls containing hydride and C1 to C5 alkyl ligands. Aluminum alkyls containing less volatile ligands (≥ C6) must be analyzed using a liquid sampling procedure. Several methods for analysis of gas mixtures resulting from hydrolysis of metal alkyls have been published. In this method, hydride content of the sample can be determined simultaneously with the other components.The method used at Akzo Nobel involves the controlled hydrolysis of the metal alkyl sample in a small, crown-capped, borosilicate glass bottle. A small amount of (1 mL) of 20 alcohol % (C10 – C12) in dry mineral oil is charged to the bottle which is subsequently capped and evacuated. The alcohol/mineral oil serves as a diluent and moderates the vigorous hydrolysis reaction. The metal alkyl sample is syringed into the bottle and mixed thoroughly with alcohol/mineral oil for 3 – 5 minutes. A small quantity of demineralized water is then syringed slowly and cautiously into the bottle to complete the hydrolysis. Little or no alkene formation (resulting from “cracking” of the metal alkyl) occurs if proper technique is employed. The hydrolyzed sample is maintained in a drying oven at 85 ± 5 °C until injection. The hydrolysis gas is transferred into an evacuated sample loop of the gas chromatograph. The sample is introduced into three columns arranged in series using argon carrier gas and attached to thermal conductivity and flame ionization detectors (Figure 1). Volatile hydrocarbon (C1 – C2) and hydrogenseparation is achieved with column 2 while C3 – C5 components are separated using column 1 as shown in Figure 1. The partial pressure of each component is determined from the peak area andthe appropriate response factor. Using the partial pressures, a mole percent value is obtained for each hydrocarbon component and hydrogen. If the product is a trialkylaluminum compound, mole percent values are converted to weight percent R3AI components in the product.Several other methods have been employed for hydride determination. A nonroutine procedure used at Akzo Nobel involves proton NMR spectroscopy where the hydride signal is quantitatively determined using Fourier transform technology. Validation tests were conducted by comparative analysis of identical samples using the GC and NMR methods. Results show that the two procedures produce results that are comparable down to very low concentrations of hydride.

a.例如:一个梳妆台的台面上三、四道6英寸的划痕确实是一个错误, 且容易引起CULL.b.例如:SPOT CHECK(不在第一道面漆使用)将会有助于使涂装更加一致.4.边角的破坏处理在任何破坏处理中都专门重要,锉痕的柔和程度决定产品破坏处理的严峻程度。
5.所有破坏(虫孔、锉痕、散敲、石块敲击等)应平均分布在产品表面和同时从边缘向内做。
B.实木修色(修绿)目的:统一木材颜色1.由于木材价格和其它因素(如季节和干燥程度),木材质量有所下降。
