In the method of the invention, a baseband signal is pre-processed to realize nonlinearity compensation. The pre-processing method comprises the following steps: the filter coefficient and the multinomial coefficient of the high power amplifier are extracted; corresponding gain is calculated for the amplitude value of each point input into the sequence of the baseband signal, and the phase compensation value is calculated according to the amplitude gain; the phase compensation value and the gain which are corresponding to each point are synthesized into re-gain, a pre-processing value pi is obtained, and pre-processing output sequence is formed; the pre-processing output sequence is output into the high power amplifier directly or through a inverse filter.

本发明方法是将基带信号进行预处理来实现抵偿非线性，预处理方法是：提取出高功率放大器的滤波器系数和多项式系数；对输入基带信号序列中的每一点的幅值计算对应的增益，根据幅度增益计算出相位补偿值；每一个点对应的相位补偿值与增益合成复增益，得到预处理值p i ，构成了预处理输出序列；将预处理输出序列直接或经过反向滤波器后输出到高功率放大器中。

In this paper,the effect of pre-stress on peen-forming is studied by experiments,the results show that pre-stress can change the relationship between pre-deformation and pre-stress shot peen deformation,and that 0.05%～0.1%pre-strain is comparetively suitable to improve the spanwise rectilinearity of shot peen-forming configuration surface.

文摘：对预应力喷丸成形进行了试验研究，指出预应力可以改变其对应的预变形与预应力喷丸变形之间的大小关系，在以改善喷丸型面纵向直线度为主要目的的预应力喷丸成形中，预应变取值0.5/1000～1/1000较为适宜。

We also use rank sum test to analyse the differe- nce between the light pre-eclampsia group and the severe pre-eclampsia group (P=0.000),the early onset pre-eclampsia group and the late onset pre-eclampsia group (P=0.003). All of the results give the same conclude that the differences within the three groups are significant (P.05). Conclusion: We conclude that HLA-G proteins are normally expressed in invasive trophoblasts and HLA-G proteins expression is defective in most pre-eclamptic placenta.We propose that trophoblasts lacking HLA-G proteins are vulnerable to attack by the maternal immune system.

结论HLA-G分子特异性分布于胎盘EVCT的胞膜及胞浆中，生理妊娠组、子痫前期组间差异性存在表明其表达量的下降与子痫前期的发病相关；轻、重度子痫前期组间显著差异表明HLA-G分子表达量的下降与子痫前期病情严重程度相关，早发型重度子痫前期患者胎盘组织中HLA-G分子的表达明显低于迟发型组，提示我们HLA-G分子表达的降低程度还与发病早晚有关。

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
