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 order to study the effects of pre-heating on the sensitivity of cells to tumor necrosis factor-α, the K562 cells were pre-heated at 40℃ for different times to induce heat shock protein 70(HSP70). To observe the effects of TNF-α concentration on the sensitivity of pre-heated cells, cells were pre-heated for 60 min and treated with TNF-α(50,100,200 and 400U/ml) for 16 hours, and the cells vitalities were detected by MTT.

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。
