一
高频功率放大器总是工作在 大信号状态 ，所 以非线性失真比较严 重。另外 ，由于现代通信系统采用 了频分多路 ，时分多路等各种 多路 调制体制，当多路载波—起进入高频功放后，各路载波信号之问会产 生互调干扰 ，使得非线失真更加严重。与小信号线性放 大器一样 ，工 程上也采用Ｐ ｄ 和Ｉ３ ｌＢ Ｐ 这两个参数作为高频功 放的线性性能指标。率 和输出功率在 某些工作状态下是相互矛盾的两个指 标 ， 在丙类工作状 态下功率放大器 的效率最高 ，但是输 出功 率不是最大 ，在 甲乙类工作 状态下输 出功率最大 ，但效 率不是最高 。

森源石化特价批180#重油\燃料油船舶用油燃料油是成品油的一种，是石油加工过程中在汽、煤、柴油之后从原油中分离出来的较重的剩余产物。
它广泛用于船舶锅炉燃料、加热炉燃料、冶金炉和其它工业炉燃料。
燃料油主要由石油的裂化残渣油和直馏残渣油制成的，其特点是粘度大，含非烃化合物、胶质、沥青质多。
燃料油的主要技术指标有粘度、含硫量、闪点、水、灰分和机械杂质。
上海期货交易所燃料油期货的交易标的是船用18 0CST燃料油，这是燃料油品种中的一种，该品种占燃料油总量的50%-75%，约3000吨以上，其中进口180CST燃料油易于期货交割，而国产燃料油由于大多包含较多其它品种，能用于交割的不多。
船用180号燃料油是一种发热量大、燃烧性能好、储存稳定、腐蚀小、使用范围广的燃油，是大马力、中、低速船舶柴油机最经济理想的燃料，同时可做中小型喷嘴的锅炉燃料，性能很好。
1、粘度：粘度是燃料油最重要的性能指标，是划分燃料油等级的主要依据，它是对流动性阻抗能力的度量。
它的大小表示燃料油的易流性、易泵送性和易雾化性能的好坏。
目前国内较常用的是40℃运动粘度（馏分型燃料油）和100℃运动粘度（残渣型燃料油）。
2、含硫量：燃料油中的硫过高会引起金属设备腐蚀和环境污染。
根据含硫量的高低，燃料油可划分为高硫、中硫和低硫燃料油。
3、闪点：是涉及使用安全的指标，闪点过低会带来着火的隐患。
4、水分：水分的存在会影响燃料油的凝点及燃料性能，会造成炉膛熄火、停炉等事故。
5、灰分：是燃料后剩余不能燃料的部分，掺入燃料油后，会加速泵、阀磨损。
如覆盖在锅炉受热面上，使传热性变坏。
6、机械杂质：它会堵塞过滤网，造成抽油泵磨损和喷油嘴堵塞，影响正常燃料。
（二）分类作为炼油工艺过程中的最后一种产品，产品质量控制有着较强的特殊性，最终燃料油产品形成受到原油品种、加工工艺、加工深度等许多因素的制约。
根据不同的标准，可将燃料油进行以下分类：1、根据出厂时是否形成商品量，燃料油可以分为商品燃料油和自用燃料油。

FT-180A 单边带电台改装成业余电台的方法
FT-180A 单边带电台改装成业余电台的方法FT-180A单边带电台是日本八重洲株式会社80年代生产的电台，部分在国内组装，国内有相当的一部分企事业单位及部队装备有此种电台，因本机具有6个固定的工作频率, 故使用灵活性较差, 现正趋于退役。
由于该电台采用恒温晶体振荡器及专用的上边带滤波器和下边带滤波器，工艺成熟，因此性能十分稳定，本机还具有体积小巧,配有专用的天调及输出功率大[最大输出功率可达100W]、并在其技术标准上符合我国的无线电技术标准的特点，所以，改制后作为业余电台使用，是相当理想的业余电台。
虽然该电台原设计的频率复盖是1.8---18MHZ，由于其是采用可调整的6个单频点的频率调整方法，所以，机内的选频放大的收发共用通道的谐振回路有相应于使用频段的配置。
因该机目前已停止生产，难以找到配置于业余波段谐振回路的器件。
因此，本文基于业余精神，介绍一种简便易行的方法，使之尽量利用原电台的器件通过改制后能工作在业余频段。
本文先介绍7MHZ业余频段的改制方法，其它频段的改制方法，将陆续介绍。
一、FT - 180A 单边带电台的特点：1、FT-180A单边带电台采用的是恒温晶体振荡器，因此，具有良好的温度特性和抗干扰特性。
由于所适用晶体的温度应达到+70℃度,故在改制中应特别的注意选择适用的晶体。
如果选不到合适温度的晶体，业余条件下，可断掉恒温箱的电源，从而使用一般的晶体，实践表明，频率的稳定性可完全满足要求。
2、FT-180A电台的第一本振为10.7MHZ晶体稳频的固定频率振荡器。
其第二本振频率的调整是利用波段开关切换6块晶体来完成，与第一本振的和频产生电台的工作频率。
通过两只边带滤波器，选择LSB或USB工作方式。
由于本机采用宽带功放，故混频器的输出信号必需进行选频放大后再送入宽带功放，以保证电台的通带特性和电台的其它指标。
本机的选频放大器是跟据频段的不同而固定配置的器件，在业余频段的使用时，是改制成业余电台的关建部位。

1、控制方式：即速度控制、转距控制、PID控制或其他方式。
采取控制方式后，一般要根据控制精度进行静态或动态辨识。
2、最低运行频率：即电机运行的最小转速。
3、最高运行频率：一般的变频器最大频率到60Hz，有的甚至
到400Hz，高频率将使电机高速运转。
4、载波频率：载波频率设置的越高其高次谐波分量越大，这
和电缆的长度，电机发热，电缆发热变频器发热等因素是密切相关的。
5、电机参数：变频器在参数中设定电机的功率、电流、电压、转速、最大频率，这些参数可以从电机铭牌中直接得到。
6、跳频：在某个频率点上，有可能会发生共振现象，特别在
整个装置比较高时；在控制压缩机时，要避免压缩机的喘振点。

See Figure2.3.Put marks at the level or grade point on the target area.NoteWhen the Product is mounted on a tripod, make sure the tripod head is perfectly level. Errors in marks can result if a tripod is out of level.Figure 2. New Horizontal or Diagonal AlignmentUse the ProductNew Vertical AlignmentTo identify new marks that are vertically aligned:1.Put the bottom of the Product on a stable surface.2.Turn on the vertical laser and aim the laser at the target area. See Figure3.3.Put marks at the point where the vertical laser intersects the target area.Figure 3. New Vertical AlignmentUsers ManualExisting Item AlignmentTo determine if an existing item is level or aligned:1.Put the bottom of the Product on a stable surface.2.Aim the horizontal or vertical laser at the target area.3.Measure the distance from the item to the laser at various distances from the Product. See Figure4.If the measurements are the same, the item is level or aligned.Figure 4. Existing Item AlignmentUse the ProductPlumb Marks (6R, 6G Only)The Product sends plumb marks up and down.New Plumb MarksTo identify new plumb marks on a ceiling or roof:1.Place a cross mark on the point to be transposed.2.Center the down laser over the cross mark. See Figure5.3.Place a mark at the point where the up laser intersects the target area.To identify new plumb marks on a floor, repeat the steps above but interchange the down and up lasers.NoteUse the floor stand with the Product to increase the sight angle of the vertical down laser.Figure 5. New Plumb MarkUsers ManualExisting Item Plumb CheckTo determine if an existing item is plumb:1.Point either the up or down laser at the target area.2.Measure the distance from the item to the laser at various distances from the Product. See Figure6.If the measurements are the same, the item is plumb.Figure 6. Existing Item Plumb CheckUse the ProductSquare Marks (6R, 6G Only)Use the vertical and horizontal point lasers to create new square marks or to determine if an existing item is square.To layout a new square for a wall or staircase (see Figure7):1.Mark a vertical line on a wall.2.Center the vertical laser on the line on the wall.3.Place the pendulum target on the floor and align the horizontal point laser with the center vertical line on thependulum target.4.Place a mark on the floor below the point of the pendulum target.5.Move the Product either closer to or farther away from the wall and redo the procedure to make another markon the floor.6.Draw a line to connect the two marks. The new line is perpendicular to the wall.Figure 7. New SquareUsers ManualCheck Product AccuracyPeriodically check the accuracy of the Product.Horizontal Laser AccuracyTo check the accuracy of the horizontal laser:1.Find a horizontal site that is almost level that is ≥4.57m (15ft) wide with two opposing walls to use as targets.You can also use scrap wood as targets. See Figure8.Figure 8. Horizontal Laser Accuracy2.Put the Product about 15cm (6in) from target .3.Aim the horizontal laser at target .4.Put a mark at the point where the horizontal laser intersects the target area.5.Turn the Product 180° on its center so that the horizontal laser intersects with target .6.Put a mark at the point where the horizontal laser intersects the target area.7.Repeat with the Product 15cm (6in) from target .8.Measure the distance between mark and mark on target and mark and mark on target .If the distances are the same, the laser is within calibration.9.If the distances are not the same, subtract the lesser measurement from the greater measurement and dividethe result by two to calculate the difference of error.If the distance of error is ≤3mm at 10m (1/8in at 30ft), the laser is within calibration accuracy. If the Product is not within accuracy, contact Fluke. See How to Contact Fluke.Check Product AccuracyVertical Laser AccuracyTo check the accuracy of the vertical laser:1.Find a door jamb that has ∼2.29m (7.5ft) clearance on both sides of the door.2.Put a center mark on the door header an equal distance from both sides of the door jamb.3.Put a cross mark (mark 1) on the floor centered on the mark on the door header. See Figure 9.4.Put a second cross mark (mark 2) ∼2.29m (7.5ft) from mark 1. Use the vertical laser to make sure thatmark 2 is centered on the door header and intersects mark 1.5.Put the Product on mark 2 with the vertical laser on.6.Put a third cross mark (mark 3) on the floor ∼4.57m (15ft) from the Product. Use the vertical laser to makesure that mark 3 is centered on the door header and intersects mark 1.7.Put a cross mark on the door header above mark 1.8.Move the Product to mark 3 and align the laser so that it intersects the centers of marks 1 and 2.9.Put another cross mark on the door header above mark 1.10.Measure the distance between the center points of the two cross marks.If the distance is ≤3mm at 10m (1/8in at 30ft), the laser is within calibration accuracy.Figure 9.
