The radiation pressure of the laser bullet is so great that the much lighter electrons are blown outward in all directions, leaving behind the more massive ions 因?yàn)榇死咨渥訌椀妮椛涔鈮合喈?dāng)大,所以會(huì)將所有較輕的電子吹到四面八方,只留下重得多的離子。
In essence, the beam pushes the lighter electrons away from the heavier positive ions, which in turn get left behind, creating a region of excess positive charge and a region of excess negative charge [ see box above ] 基本上,這會(huì)將較輕的電子從較重的離子中推開(kāi),這時(shí)候較重的離子會(huì)略為落后,而創(chuàng)造出一個(gè)帶有較多正電荷的區(qū)域及另一個(gè)帶有較多負(fù)電荷的區(qū)域(參閱上方在電子泡泡里)。
