threshold excitation

基本解释

The phenomenon of electron resonance near the excitation threshold and its mechanism are discussed.
在激發閾值附近，發現了分波共振現象，竝對這個現象産生的機制作了分析。
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：對5例行SPR患者進行術中電刺激閾值及行爲反應觀察，對閾值較低、有反應擴散現象的神經小束予以切除。
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.
這樣，我們就可以觀察到一些新的現象，如多光子過程，閾上電離，隧道電離等。
