这是一门依据实验数据，进行理论计算、推导，从而总结实验规律的学科．它需要坚实的理论基础，渊博的数学、物理知识。唐敖庆完全具备这些条件。 唐敖庆以知荒者的勇气在我国第一个开始了理论化学的研究： 量子化学（也称物质结构）是理论化学的一个重要组成部分。它研究的对 This is a subject based on experimental data, theoretical calculations, derivation, and thus summarize the experimental law. It requires a solid theoretical foundation, profound math, physical knowledge. Tang Aoqing fully possess these conditions. Tang Aoqing first learned the theory of chemistry in China with the courage of the wasteland: Quantum chemistry (also called material structure) is an important part of theoretical chemistry. It studies right
