threshold excitation

基本解释

The phenomenon of electron resonance near the excitation threshold and its mechanism are discussed.
在激发阈值附近，发现了分波共振现象，并对这个现象产生的机制作了分析。
Methods:To observe the electrical threshold of excitation and behavior reaction of 5 cases during the SPR resect the nerve fasciculus of lower threshold and reacted spreading phenomenon.
方法：对5例行SPR患者进行术中电刺激阈值及行为反应观察，对阈值较低、有反应扩散现象的神经小束予以切除。
In this case, many interesting phenomena of excitation and photoionization can be observed, for instance, muti-photon ionization, above threshold ionization, tunnel ionization and so on.
这样，我们就可以观察到一些新的现象，如多光子过程，阈上电离，隧道电离等。
