查询词典 Pressure

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。

Blood pressure should be reduced to normal level to prevent heart and cerebral vessels to occur arteriolosclerosiswhen the blood pressure of hypertensive patient is not very highor the duration of illness is short. when blood pressure rises very high or the course of disease is long, blood pressure should be lowered to slightly higher than normal blood pressure level, so it can prevent arteriolosclerosis to be deteriorated further and can prevent the occurence of cerebral ischemia and infarction.

The reliability of analysis result depends largely on the in-house experimental conditions. Unlike the previous analysis that only concerns the sole effect of permeable pressure, this article considers both permeable and confining pressure and deformation characteristics of concrete material under the interaction of them according to the real work state of construction, which may leads to the changing pattern of permeable rate as listed below: permeable rate always reaches its peak with the time process going on, than goes down and remains straight on some certain value; The PR will tend to decline while the confining pressure is increased, and the time taken before the peak will be extended as well; Under the constant permeable pressure and circularly changing confining pressure, the minus-exponential ascend and descend relationship could be applied between the PR and Time axes respectively with crannied and intact concrete samples, and the PR of crannied concrete is far more larger than that of intact concrete. The change pattern of concrete could also be mathematically analogized using the least square method.

室内的实验条件是研究成果可靠性的重要因素，而以往的研究都只考虑了渗透压单一作用，本文根据混凝土结构的实际工作状态，同时考虑了围压与渗透压共同作用下的混凝土材料的渗透性变化特征，得出了混凝土材料在围压作用与渗透压共同作用下的渗透率的变化规律：渗透率都是随时间推移先达到一个峰值，再降低并趋于平稳；渗透率会随围压的增大而减小，并且峰值的到达时间也会随之延长；在渗透压不变，围压升降循环的情况下，有裂缝、无裂缝混凝土的渗透率变化规律是随时间成负指数关系上升、下降，且有裂缝混凝土试件的渗透率远远高于无裂缝混凝土的渗透率，并对混凝土的变化规律运用最小二乘法进行数学拟合。
