This compound was identified by C, H and N elemental analysis and quantitative analysis of Cs atom. The molecular formula is Cs(ATZ). The physicochemical properties were characterized by FT-IR, Raman spectroscopy and X-ray power diffraction and the peaks of FT-IR were also assigned.展开更多

从8月初伯纳乌杯点球建功,率领拜仁抢走皇马百年庆典的荣光,到当月中旬被《踢球者》评为年度德国足球先生;从德甲第2轮为新东家打入首粒联赛进球,到冠军联赛也为拜仁攻陷城门;从9月8日欧洲杯预选赛首轮为德国队首开纪录,到联赛梅开二度...从8月初伯纳乌杯点球建功,率领拜仁抢走皇马百年庆典的荣光,到当月中旬被《踢球者》评为年度德国足球先生;从德甲第2轮为新东家打入首粒联赛进球,到冠军联赛也为拜仁攻陷城门;从9月8日欧洲杯预选赛首轮为德国队首开纪录,到联赛梅开二度使拜仁位居榜首(失去他的勒沃库森却是一片惨淡)……新赛季以来,巴拉克可谓遍地开花,以风暴般的力量摧毁对手的同时,也征服着慕尼黑、德国乃至欧洲。一时间诸如"慕尼黑的上帝"、"伟大的斗士"、"中场王"等赞誉从天而降,纷纷加在这位德国足球新皇帝身上,集万千宠爱于一身。不只球迷、队友和主帅对他大加赞扬,昔日德国足坛的名宿们也坐不住了,前有内策尔出来妙笔生花,然后"先皇"贝肯鲍尔也开金口,称巴拉克会比齐达内做得更好,将成为欧洲之王。红得已经发紫的巴拉克在球场上的表现已经尽人皆知,那么他的生活无疑更是人们想了解的话题,现在就一起来看他A TO Z 的自述吧,以首个字母排序的单词可是德语的——展开更多
