"This is an exciting discovery because it extends the time range for liquid water on Mars, and the places where it might have supported life," said CRISM principal investigator Scott Murchie of the Johns Hopkins Applied Physics Laboratory in Laurel, Md. The identification of opaline silica tells us that water may have existed as recently as 2 billion years ago.

" "这是个令人兴奋的发现，因为该发现延长了水在火星上的存在时间，也扩大了可能支持生命存在的范围，"专用小型侦察影像频谱仪的主要研究人员、马里兰州劳瑞尔市约翰霍普金斯应用物理实验室的斯科特·默基说，"蛋白石硅酸盐的发现使我们可以断定：仅仅20亿年前，火星上仍有水存在。

The changes of nutrition in milk treated with different technologies are also determined. Results showed that, 1 higher pressure, longer holding time and more alternative times favour a larger destruction of microorganisms; 2 the combined effect of hurdle technology and pressure on the destruction of microorganisms in fresh raw milk is more effective than only using pressure treatment, among which the effect of ε-polylysine on inactivation of microorganism in fresh raw milk is more effective than that of Nisin with the same concentration of 100mg/L; 3 the whole proteins in milk treated by the different types of sterilization have been detected by SDS-PAGE electrophoresis, and comparing with the whole proteins' electrophoretogram of fresh raw milk, we found that the first spectrum band near the negative pole was disappeared and the colours of the second spectrum band was tint in UHT, pasteurism and 500MPa treated milks, which was suggested that some proteins' subunits were dissociated, but the 400MPa treated milk showed the similar eletrophoretogram with the fresh raw milk; 4 the loss of threonine, VA and VC in high pressure treated milk was more less than those in pasteurism treated milk, in particular threonine and VA were almost retained, and the contents of VB1 and VB2 in the former are also more than that in the latter; 5 high pressure treated milk had longer shelf life than pasteurism treated milk, extending the sale semidiameter of milk.

压力越高，保压时间越长，交变次数越多，杀菌效果越好；2）采用栅栏技术对牛乳中的微生物具有更有效的杀菌作用，其中相同浓度的（终浓度100mg/L）ε-聚赖氨酸较Nisin具有更强的杀菌效果；3）利用SDS-PAGE电泳研究了不同杀菌方式对牛乳总蛋白的影响，发现经UHT、巴氏和500MPa交变处理的牛乳与生鲜牛乳相比其总蛋白电泳图谱靠近负极方向第一条谱带消失，第二条谱带颜色变浅，由此推测经上述处理后牛乳中有一些蛋白质的亚基发生了解离，而经400MPa交变处理的牛乳与生鲜牛乳的总蛋白电泳图谱相似；4）超高压牛乳营养成分与生鲜牛乳相比，苏氨酸、VA、VC在超高压处理中受到的破坏明显比巴氏杀菌小得多，特别是苏氨酸和VA几乎完全被保留下来，而VC含量也要比巴氏奶高出25%以上，对于VB1、VB2，检测数据也表明，超高压灭菌对其破坏要比巴氏灭菌小，其含量分别比巴氏杀菌牛乳高出9.5%和2.6%；5）与巴氏杀菌乳相比，超高压杀菌有助于延长牛乳的保质期，扩大牛乳的销售半径。
