The fresh-keeping effects of Portunus Trituberculatus were investigated. The results showed the efects were better when air components and ratios of MAP were CO2 50% N2 50%. Compared with coating package and MAP, vacuum packing could inhibit the production of melanin in Portunus Trituberculatus gills and legs and prolong storage period effectively at 0-4℃.

结果表明：气调包装气体配比为CO2 50%，N2 50%的保鲜效果较好；但真空包装与气调包装和涂膜包装的保鲜效果相比，0～4℃下，真空包装可有效抑制梭子蟹腮部和足部褐变并延长三疣梭子蟹保鲜期，保鲜效果好于气调包装和涂膜包装。

CO2 is a safe natural refrigerant which had been and will be used in air conditioning andheat pump systems.

CO2是一种安全可靠的自然工质，可望在空调和热泵系统中得到应用。

The results showed that the addition of alcoholate increased the elution recovery of phenolic acids on resins in supercritical CO2. The infrared spectroscopy was used to study the interaction between solute and solvent molecules in supercritical fluid. The hydrogen bond between alcoholate entrainer and phenolic acid was the main factor to increase the ability of supercritical elution. The results appeared that salvianolic acids could be extracted by supercritical carbon dioxide with ethanol as entrainer.

结果表明：醇类夹带剂的加入能大大提高树脂上酚酸类化合物的超临界洗脱率；通过红外光谱技术研究了超临界流体中分子间的相互作用与超临界洗脱过程的关系，认为醇类夹带剂与酚酸类化合物的氢键作用是提高酚酸类化合物洗脱率的主要因素；以乙醇为夹带剂的超临界CO2洗脱可应用于丹参酚酸的提取。

The polyphenols of the beer fermented under the optimum processing was 101.78 mg/ L, which was close to the international standard 100 mg/L. The chroma, the total nitrogen, the total acid, pH, alcoholicity, diacetyl and CO2 of the product beer were close to that of Zhujiang beer

该优化工艺发酵的啤酒多酚值为101.78mg/L；总氮、色度、PH、总酸、酒精度、双乙酰、CO2与所测的珠江啤酒的指标接近。

But partial staff member disinfects technical inexperience, the disappear venom chroma that make up is unqualified, alexipharmic time is insufficient, all be the cause that causes a bacterium to exceed bid. 2.2 small microclimate and air quality circumstance indoor temperature, wind speed and CO2 content all accord with 6 guesthouse wholesome requirement.

但部分工作人员消毒技术不熟练，配制的消毒液浓度不合格，消毒时间不够，均是导致细菌超标的原因。2.2微小气候和空气质量情况6个宾馆室内温度、风速和CO2含量均符合卫生要求。

The reaction performance that the soda acid sex of carrier and the size of the area that compare a list affect activator directly, of the compound carrier surface that decorates via alkaline-earth metal alkalescent increase, rose to leave capacity to the adsorptive solution of CO2, activation agent is shown in reforming reaction better fight carbon deposit ability.

载体的酸碱性和比表面积的大小直接影响到催化剂的反应性能，经碱土金属修饰的复合载体表面的碱性增强，提高了对CO2的吸附解离能力，使催化剂在重整反应中表现出较好的抗积炭能力。
