By using a fracture simulation unit,the regularity that temperature,flow rate and fracture width influence on HCl/dolomite reaction rate is investigated.The sequence of temperature,flow rate,acid concentration and fracture width influence to the acidic rock reaction rate is also studied in a four factors and four levels orthonormal test,and the sequence that acid concentration>flow rate>temperature>fracture width is found.At the last,the possible HCl/dolomite reaction mechanism model which can explain the influence factors is derived.

The results showed that both increasing the KMnO4 concentration and using acidic or alkaline solution promoted the removal of Hg^0. The reasons are that H2SO4 in solution facilitates the adsorption of Hg^0 on MnO2, and that free radical OH produced in alkaline solution can oxidate Hg^0. High temperature has a negative effect on the removal of Hg^0, and the effect of Hg^0 initial concentration can be neglected.
研究结果表明,高猛酸钾初始浓度的增加、强酸或强碱条件均有利于Hg^0的去除,H2SO4的存在促进了Hg^0在MnO2上的吸附,而强碱水溶液中产生的OH间接氧经了Hg^0;反应温度的升高抑止了Hg^0的去除,而Hg^0初始质量浓度对反应的影响可忽略;KMnO4。

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。

Were extracted by different extracting solvents in lab, the results indicated that with the increasing of Mn concentration levels, the speciation of Mn in their roots transform from H2O-extractable species to HCl-extractable species and NaCl-extractable species, showed increases of Mn of oxalate binding and pectate binding or prontein binding in cell wall of roots; Mn of H2O-extractable species were 34.55~50.26% of total Mn in stems and increased with the increasing of Mn concentration levels, which benefited upward transport of Mn; Percentage of Mn of H2O-extractable species were 38.55~44.19% and Mn of HCl-extractable species were 20.66~28.74% to total Mn in leaves, suggesting that most Mn in leaves were the speciation of H2O-solubility organic salts or manganese oxalates. 5.

不同的提取剂对水蓼根、茎、叶的提取结果表明,随着锰处理浓度增加,水蓼根中Mn由水提取态向盐酸提取态和氯化钠提取态转化,说明根细胞壁结合的草酸盐和果胶酸盐或蛋白质结合态的Mn含量随锰处理浓度的增加而增加;在茎中,水提取态锰含量占总锰的34.55-50.26%,且随锰处理的增加其水提取态锰的比例增加,这有利于锰向上运输;水蓼的叶片中,水提取态锰占总锰的38.55-44.19%,盐酸提取态锰占总锰的20.66-28.74%,说明叶片中的锰大部分以水溶性有机盐或草酸锰的形态存在。
