The BT100 features two different channels: a distortion channel, featuring Crate’s exclusive Shape control for quick and easy access to the tone you need, and a clean channel with a four-band rotary EQ. Another unique and valuable feature of this amplifier is the Octave control. This feature electronically creates a second signal that is one octave lower than the original signal. An active electronic tuner, conveniently located on top of the amplifier, allows you to get in tune and stay in tune “on the fly.” The Mute switch allows you to tune in silence without changing the channel Level controls. A built-in Limiter keeps your sound clean even at full output power levels, and front panel jacks are provided for connecting a CD player and a pair of headphones, thereby optimizing your practice time.Like all Crate products, your BT100 is designed by musicians and built using only the best components. Extensive testing at the hands (and ears) of skilled technicians and musi-cians insures you that this amplifier is the absolute best it can be.In order to get the most out of your new bass amp, we urge you to check out the infor-mation in this manual before you begin playing.And thank you for choosing Crate.Declaration Of Conformity#34, Effective 01-01-2001Manufacturer’s Name:SLM ElectronicsProduction Facility:1901 Congressional Drive, St. Louis, MO 63146, USAProduction Facility:700 Hwy 202 W, Yellville, AR 72687, USAShipping Facility:1400 Ferguson Ave., St. Louis, MO 63133, USAOffice Facility:1400 Ferguson Ave., St. Louis, MO 63133, USAProduct Type:Audio AmplifierComplies with the following Standards:Safety:EN60065, E60065, C22.2, UL6500 and/or UL813EMC:Directive 89/336/EEC, EN55103, EN55013, EN61000,and/or FCC 47CFR 15B clASupplementary information provided by:SLM Electronics - R & D Engineering1901 Congressional Drive, St Louis, MO 63146, USATel.: 314-569-0141, Fax: 314-569-0175341. INPUT:Use this 1/4” jack to connect your bass to the amplifier by means of a shielded instrument cable.2. -15dB/0dB:Use this switch to match the output signal level of your instrument to the amplifier. If your instru-ment has standard pickups, setting the switch to the 0dB position (switch in the out position) should yield the best results. If your bass has active electronics or high output pickups, set the switch to the -15dB position (switch depressed).3. MUTE:This switch, when depressed, interrupts the signal prior to the power amplifier, allowing you to tune your instrument in silence.4. GAIN:Use this control to adjust the amount of distortion for the Distortion channel. As you rotate the control clockwise the amount of distortion increases.NOTE:The BT100 employs an internal noise gate on the Distortion channel to keep residual noise to a minimum.The Clean channel’s Level control (#8) must be turned up above “0” in order for the noise gate to trigger proper-ly. The Gain control (#4) and input signal level also affect the noise gate.5. SHAPE:Use this control to adjust the tone of the Distortion channel, from a studio “V”-shaped tone to a more “live,” more present sound.6. LEVEL:Use this control to adjust the output level of the Distortion channel.7. CHANNEL SWITCH:Use this switch to select either channel. With the switch in the out position, the Clean channel is selected. When the switch is depressed, the Distortion channel is selected. The adjacent LED illumi-nates when the Distortion channel is selected. NOTE:When using a footswitch: when this switch is depressed,the footswitch switches between the Distortion channel and the Clean channel; when this button is in the out posi-tion, the Clean channel is always active, and the footswitch turns the Distortion channel on and off, allowing you a blend of both channels.8. LEVEL:Use this control to adjust the output level of the Clean channel, and as part of the Octave level control (see #13).9. LOW:Use this control to adjust the low frequency output of the Clean channel.10. LOW MID:Use this control to adjust the lower-midrange frequency output of the Clean channel.11. HIGH MID:Use this control to adjust the upper-midrange frequency output of the Clean channel.12. HIGH:Use this control to adjust the high frequency output of the Clean channel.13. OCTAVE:The BT100 features internal circuitry which creates a second signal which is one octave lower than the input signal. Use this control in conjunction with the Clean channel’s Level control (#8) to adjust the level of the octave signal.14. MASTER:Use this control to adjust the overall output level of the amplifier.15. LIMIT LED:This LED illuminates when the internal limiting circuit is active. Occasional flashing during play-ing is normal. If the Limit LED remains illuminated, reduce the output level of the amplifier until the LED flashes.16. CD INPUT:Use these RCA jacks to connect the line level (or headphones) output of a CD player, tape deck or rhythm machine to the amplifier. The signal level from these jacks is adjusted by the Master control (#14). If the signal from the source connected to these jacks is too strong, use the output level control on the source to adjust the signal to obtain the proper level for a good mix.17. HEADPHONES:Use this jack to listen to the amplifier through a pair of stereo headphones. The internal speaker is disconnected when the headphones jack is used. To avoid possible damage to your hearing, do not use headphones for extended periods of time at extremely loud listening levels.The Front Panel:518. POWER:Use this switch to turn the amplifier on and off. The adjacent LED illuminates when the amplifier is turned on.19. ELECTRONIC TUNER (top panel, not shown):This active electronic tuner is on whenever the amplifier is turned on, allowing you constant, “real-time” tuning. The tuner is fully chromatic – use the flat and sharp indica-tors until the LED between them illuminates, indicating proper tuning.The Rear Panel:20. AC LINE CORD (not shown):The grounded power cord should only be plugged into a grounded power out-let that meets all applicable electrical codes and is compatible with the voltage, power, and frequency require-ments stated on the rear panel. Do not attempt to defeat the safety ground connection.21. EXTERNAL SPEAKER:Use this jack to connect the amplifier to an external speaker cabinet. This jack is wired in series with the internal speaker, which remains active when this jack is used. A 4 ohm external speaker cabinet is recommended.22. FOOTSWITCH:Connect a two-button footswitch (such as the Crate CFS-2) here for remote control of the channel selection/“blend” (see #7) and octave on/off. (When the Channel Switch [#7] is depressed, the footswitch switches between the Clean channel and the Distortion channel; when the switch is in the out position, the Clean channel is always active, and the footswitch turns the Distortion channel on and off, allowing you a blend of both channels.)23. EFFECTS LOOP SEND:Use this jack to connect an external signal processor to the amplifier by means of a shielded signal cable. Connect the other end of this cable to the input jack of the external processor.24. EFFECTS LOOP RETURN:Use this jack to connect an external signal processor to the amplifier by means of a shielded signal cable. Connect the other end of this cable to the output jack of the external processor.25. BALANCED LINE OUT:Use this XLR jack to send a balanced line level signal to an external power amplifi-er, mixing board, or recording console.26. PRE/POST:Use this switch to determine whether the Balanced Line Out signal is Post-EQ (switch depressed)or Pre-EQ (switch in the out position).27. GROUND LIFT:This switch, when depressed, lifts the ground connection at the Balanced Line Out jack (#25).This may help reduce hum in the Balanced Line Out signal.28. VOLUME: Use this control to adjust the signal level at the Balanced Line Out jack (#25).POSTGND67BUFFEREQNOISE GATETUNERA BC D EF GSHAPEOCTAVEBALANCED EFFECTS BLENDEXTERNAL SENDPHONESPOWER SPEAKERATTENUATORRETURN SWITCHING CIRCUITRYBT100 Technical Specifications:Specifications subject to change without notice©2003 ST.

聚四氟乙烯材料力学性能参数表

1．聚四氟乙烯聚四氟乙烯是用于密封的氟塑料之一。

聚四氟乙烯以碳原子为骨架，氟原子对称而均匀地分布在它的周围，构成严密的屏障，使它具有非常宝贵的综合物理机械性能(表14—9)。

聚四氟乙烯对强酸、强碱、强氧化剂有很高的抗蚀性，即使温度较高，也不会发生作用，其耐腐蚀性能甚至超过玻璃、陶瓷、不锈钢以至金、铂，所以，素有“塑料王”之称。

除某些芳烃化合物能使聚四氟乙烯有轻微的溶胀外，对酮类、醇类等有机溶剂均有耐蚀性。

只有熔融态的碱金属及元素氟等在高温下才能对它起作用。

聚四氟乙烯的介电性能优异，绝缘强度及抗电弧性能也很突出，介质损耗角正切值很低，但抗电晕性能不好。

聚四氟乙烯不吸水、不受氧气、紫外线作用、耐候性好，在户外暴露3年，抗拉强度几乎保持不变，仅伸长率有所下降。

聚四氟乙烯薄膜与涂层由于有细孔，故能透过水和气体。

表14-9聚四氟乙烯性能聚四氟乙烯在200℃以上，开始极微量的裂解，即使升温到结晶体熔点327℃，仍裂解很少，每小时失重为万分之二。

但加热至400℃以上热裂解速度逐渐加快，产生有毒气体，因此，聚四氟乙烯烧结温度一般控制在375～380℃。

聚四氟乙烯分子间的范德华引力小，容易产生键间滑动，故聚四氟乙烯具有很低的摩擦系数及不粘性，摩擦系数在已知固体材料中是最低的。

聚四氟乙烯的导热系数小，该性能对其成型工艺及应用影响较大。

其不但导热性差，且线膨胀系数较大，加入填充剂可适当降低线膨胀系数。

在负荷下会发生蠕变现象，亦称作“冷流”，加入填充剂可减轻蠕变程度。

聚四氟乙烯可以添加不同的填充剂，选择的填充剂应基本满足下述要求：能耐380℃高温即四氟制品的烧结温度；与接触的介质不发生反应；与四氟树脂有良好的混入性；能改善四氟制品的耐磨性、冷流性、导热性及线膨胀系数等。

常用的填充剂有无碱无蜡玻璃纤维、石墨、碳纤维、MoS2、A123、CaF2、焦炭粉及各种金属粉。

如填充玻璃纤维或石墨，可提高四氟制品的耐磨、耐冷流性，填充MoS2可提高其润滑性，填充青铜、钼、镍、铝、银、钨、铁等，可改善导热性，填充聚酰亚胺或聚苯酯，可提高耐磨性，填充聚苯硫醚后能提高抗蠕变能力，保证尺寸稳定等。

The charge station can operate in two modes. In the first mode ”free charging”, is the charging started as soon as you connect the plug to the charging station. In the second mode, ”RFID mode”, is the charging not started until the user has been authenticated via RFID. Free charging In the free charging mode is the charging started immediately when the charging plug is connected. The LED strip turns blue when charging starts. See chapter LED strip for explanation of the LED strip behaviour. RFID mode In the RFID mode is EV driver required to authenticate him/herself to the charging station before the charging session starts. The use case for RFID is as follows:1. EV Driver connects cable to charge station (before RFID tag identification takes place).2. Charge station blinks twice in green to indicate that it has detected cable connected.3. EV Driver puts RFID tag above RFID window on charge station4. Depending on authentication result:a. Charge station blinks blue when RFID tag detected and accepted. Charging starts immediatelyb. Charge station blinks red when RFID is detected and rejected. Charging does not start.5. For successful RFID authentication is the LED ring blue until the cable is unplugged.6.

常吃这两类食物100%患肝癌
肝脏是人们身体最重要的器官，负责人体的消化和新陈代谢，而肝癌虽然大部分是由肝炎诱发导致的，但也跟人们日常生活的饮食习惯有密切的关系，一旦饮食中吃了容易致癌的物质，稍微不注意就会诱发肝癌。

常吃两类食物容易诱发肝癌
①发霉的食物不能食用
真菌中的黄曲霉毒素为致癌物质，该毒素能诱发人、猴、鼠、禽类发生肝癌，致癌所需时间最短为24周。

预防真菌污染食物，应注意：1、家藏花生、玉米、白薯干、稻米、小米等一定要晒干晒透，存放在干燥通风环境中。

2、发霉的花生、薯干、萝卜干等应剔除丢弃，人畜家禽均不能食用。

3、花生油及棉籽油均不宜久贮;当怀疑大批粮油、奶类食品有真菌污染时，应请防疫站检查，允许后才能发放、销售或食用。

②动、植物油有哈喇味后不宜食用
陈腐油类中均含有一种化学成分，它能使蛋白质的结构变异，导致变异蛋白质的细胞失去正常功能并向初期癌细胞转化。

此外，还有的化学成分酸的复制使人的老化过程加快。

因此，动、植物油切勿存放太久，已变质产生哈喇味的油不宜食用。

用有哈喇味的油炸炒制的食品不仅味道不好，更重要的是能导致癌症，缩短寿命。
