She studied physics at the University of Leipzig in the 1970s and physical chemistry in Berlin in the 1980s.

20世纪70年代，她在德国莱比锡大学攻读物理学，80年代在柏林学习物理化学。

Chemistry has traditionally been subdivided into four areas: organic, inorganic, analytical, and physical chemistry.

化学被传统地分为四个领域：有机化学、无机化学、分析化学和物理化学。

Ageing in this case must occur according to the laws of physical chemistry and of thermodynamics.

。 在这种情况下， 老化必须根据物理化学和热力学定律发生。
