New, and straight from the Barber Custom Shop, The Barb EQ adds cool Blackface-sounding controls to the 5E3 Tweed Deluxe and to amps using single or no tone knob designs. The Barb EQ has three controls, volume, treble and bass. Your Tweed Deluxe will sound much larger and very much like the sweetest Blackface Deluxe you ever heard, with greatly enhanced volume control and input headroom. Just add this in front of your small to medium amp, and enjoy the ability to footswitch bubbly BF style tone into any amp. The Barb E.Q. also can attenuate better and with much improved frequency response than any guitar's volume knob, as well as being able to boost your signal if needed. The true bypass has an effect insert to allow simplied switching of other pedals. The Barber E.Q. uses a voltage booster to run internally at 25 volts, and externally uses 9 volts (either battery or optional adapter) to keep life simple.

这类产品一直是哥喜欢的，不过国内买不到特别能用的，哥自己也只有一块儿ELECTRO-HARMONIX的TUBE EQ，虽然声儿好但是噪音有点儿操蛋个头儿又大跟个便当盒子似的，而且哥自己也极其腻味电子管儿的维护与更换， CARL MARTIN的吧李大胡子又说不好使，声儿太干，想托人带个SADOWSKY PREAMP DI 吧又太TM贵了，哥也后悔前段儿时间邱培容出呀内块儿SADOWSKY 的时候儿哥没出手，不过哥还是希望有个BARTOLINI 的TCT PEDAL，内才是MARCUS MILLER用的，最近看到 ATELIER Z也出了不少类似产品，价格也不高，不过日本子内边儿购买有点儿不方便啊，我操这下可好了， BARBER 出这个正是哥喜欢的哥说实话极其腻味给FENDER用MID-RANGE CONTROL过者DRIVE类BOOST

ABSTRACT: A Rockwell PowerFlex7000 Variable Frequency Drive is used in JiuZHou Electric medium voltage drive test bay as the converter. Because of it belong to the current source drive, it has the function of the four quadrant, it can achieve the energy feedbackmake the motor brake,also has the advanced vector control technology, so it can achieve all kinds of load test, there are no other drives can replace it in simulate motor load. PowerFlex7000 drive has ability to achieve the full load test before the drive leave factory.

摘 要：罗克韦尔PowerFlex7000变频器在九洲中压变频实验站测试系统中作为变流逆变器使用，由于本身属于电流源型变频器，具有四象限运行功能，能够实现能量的回馈和对电机的制动，先进的矢量控制技术，可以实现各种复杂多变的负载特性，在模拟电机负载方面起到了其他变频器无可替代的作用，实现了变频器出厂之前的满负荷测试。

The pulse propagation through fog medium is discussed .The pulse distortion induced by fog is found using method of closed solution for Fourier integral in time domain. It is found that the pulse distortion is affected by the visibility, frequency, pulse width and path length.

The computing plots of the solutions from the two methods were inconsistent under the specified boundary-initial conditions, which stirred up the debate of the effectiveness of Maxwell's equations in lossy medium. It is found that the differences between the two numerical curves can be viewed as the Gibbs phenomenon caused by cutting off the high frequency components in computing the infinite integral of the numerical curve of Harmuth's solution.

通过比较两种解析解的数值曲线得出：两者的差异在于求解Harmuth解的数值曲线时，采取无穷积分的高频截断近似产生了吉布斯现象；在计算Harmuth解的数值曲线时不断增大积分上限，其数值曲线的振荡不断向不连续点处收缩，而且衰减加快，因此在求解Harmuth解的数值曲线时，若积分区间取为理想无限大，则可以预见相同计算精度下两种方法的电场解的数值曲线是一致的。
