The stability of genetic carrier (cluster) is dependent on the competition between repetitious cooling and heating impulse as well as effects of electric pulse modification.

遗传载体—团簇的稳定性在于反复冷热激励与电脉冲孕育两因素的竞争。

After analyzing the spectrum of a group of signals, non-polar differential exponent pulse signal was selected as carrier wave, which can separate therapy threshold and ache threshold.

通过对载波信号的频谱分析，提出了一种能分离治疗阈值与疼痛阈值的无极性指数脉冲。

But to the CW pulse signal with changing carrier wave frequency, common filter cannot achieve narrowband filter, whereas broadband filter cannot reach the request of the signal-noise ratio.

可是，对于载波频率不断变化的CW脉冲信号，普通的滤波器难以实现窄带跟踪滤波，而宽带滤波又不能达到提高信噪比的要求。
