The supermolecule system building on the weak interactions between molecules has always been the focus on chemistry , bionomy , material science and informatics theoretically and experimentally . However , because the experiments fail to provide varied information in detail .

通过分子间弱相互作用构筑的超分子体系一直是化学，生命科学，材料科学，信息科学领域在理论和实验上的研究焦点，但对于分子间的相互作用体系，实验研究不能提供十分详细的各种信息，所以量子化学计算在补充其结构，能量，光谱等信息上有着重要的意义。

We present a simple approach to determine the content of casein in crosslinked polyacylamide, i. e., protein molecules are complexed with copper ions by biuret reaction. The polymer containing proteins is cinerated at high temperature and then the residue is dissolved into nitric acid. Protein content is measured by determining concentration of copper ion in nitric acid solution using atomic absorption spectrum.
