The first biological effect of ionising radiation is the absorption of energy , leading to the removal of electrons from atoms . this occurs almost instantaneously and is followed by chemical damage to cells , which can include damage to dna 第一,電離輻射能吸收能量,令電子脫離原子,這過程差不多即時發生,令細胞因化學反應而受損,包括脫氧核糖核酸dna 。
And 15vol . % tic were tested . results of mechanical properties indicated that the introduction of small quantities of ti2alc can improve the mechanical property , due to the absorption of energy of particles flexibility . however , further increasing of ti2alc is disadvantage to the mechanical property 力學性能測試結果說明,少量tizaic的引入,使得材料中增加了顆粒增韌的能量吸收機制,這也可以提高材料的力學性能;然而過多的tizaic含量對材料的力學性能不利。
