凝石技术挑战传统水泥工艺

水泥作为大宗基础建筑材料，是利用地壳丰度前5名的氧、硅、铝、铁、钙元素，通过检验尺度为70m的均化和1400℃高温处理，以低廉成本生产出来的物理和化学性能堪与天然石材媲美的可塑性建筑材料。尽管水泥工业的技术进步一直没有停步，其”两磨—烧”的基本原理诞生100年来迄今未发生变化，而科学家发明的凝石技术却跳出固有的思维。“高温固体排放物凝石化”使固体废弃物成为有用资源，     

Comparison of Yeast Inactivation Treated in He, Air and N2 DBD Plasma

In this paper, the mechanism of yeast inactivation in low temperature atmospheric pressure helium, nitrogen and air plasmas generated by dielectric barrier discharge is analysed and compared. The results show that all the three gas plasmas have a high germicidal efficiency. The morphology of the yeast is observed by scanning electron microscopy, which reveals that the yeast treated in helium plasma is ruptured completely but there are only some flaws on the cell walls in the nitrogen and air plasma treated samples. Also, the flaws on the cell walls treated by air plasma are more significant than that by nitrogen treatment. Simultaneously, the pH values of the samples after 5 rain nitrogen and air plasma treatment have no remarkable change either, while the sample treated with helium plasma descends below 4.0, which is beyond the optimum one for the yeast＇s living environment. The difference in pH values may be caused by the treatment effect and the degree of the cell＇s rupture when the gas discharge plasma treatment is applied.

长江枝江段凤凰滩现代沉积特征

长江枝江段凤凰滩为一典型的加积心滩，沉积物自滩头至滩尾为砾、沙、粉沙和泥。滩头发育大中型沙浪、新用形沙垅和舌状沙垅；滩中发育大型泥裂，滩尾仅发育小波痕，层理类型以大型槽状和板状交错层为主，层理规模自滩头向滩尾逐渐减小。根据沉积物特征及沉积构造可划分为１６种岩石相类型，它们构成了１０种岩石相组合类型。滩体建筑结构要素分析表明，凤凰滩由纵向砾石坝、纵向前积沙坝、侧向粉沙坝、垂向河漫滩和弧形沙坝５种建筑
