By using multi-dimensional nuclear magnetic resonance method we have studied the folding mechanism of staphylococcal nuclease in vitro; the tertiary interactions for folding of SNase fragments into native-like conformation; the interaction between SNase N- and C-terminal subunits; the relationship of enzyme activity with folding and dynamic states of SNase; the structural properties of enzyme protein while exert its function. We have studied the internal motions of thermophilic Archaea protein Ssh10b and mechanism of its heat-resistance using the NMR 1H-15N relaxation and H/D exchange methods. We have determined the 3D solution structure of human translationally controlled tumor protein TCTP and the Ca2+-binding site; determined the 3D crystal structure of human mitoNEET, a novel protein from distinct groups of iron-sulfur proteins; determined the 3D solution structure of a novel chromatin protein Cren7. Determination of SNase-DNA and Archaea protein-DNA complex structures are in progress.

The price pricking beer is 3 5 times higher than familiar equal amounts beer , investigates whose cause to have several aspect down: One, has been fresh beer because of it , has kept fine taste of beer and nutrition; That sterile condition demands is strict among it's two , procedure of production, equipment investment is big, be going to want the strict sterility course film fliteration or hole fliteration, besides all microorganism , beer barrel and production environment before irrigating dress; It's three , marketing way have been unique , had been going carrying out the carbon dioxide cooling down and supplementing by the fact that fresh beer sells machine, have made use of carbon dioxide pressure to give beer and , have avoided beer contacting air but have produced oxide taste; It's four, has been that scheduled time is not long because of barrelled fresh beer guarantee quality , the dealer has born certain risk, if being able to not sell out in time, meeting bring about very big economic losses.

扎啤的价格比同等量的熟啤酒高3—5倍，究其原因以有下几个方面：其一，因为它是鲜啤酒，保持了啤酒良好的口味和营养；其二，生产过程中，无菌条件要求严格，设备投资大，在灌装前要经过膜过滤或孔过滤，除去所有的微生物，啤酒桶和生产环境也要严格无菌；其三，销售方式独特，要过通过鲜啤酒销售机进行降温和补充二氧化碳，并利用二氧化碳压送啤酒，避免了啤酒接触空气而产生氧化味；其四，是因为桶装鲜啤酒的保质期不长，经销商承担了一定的风险，如果不能及时售出，会造成很大的经济损失。
