The work not only disclosed the mechanism of order structure formed in wave growth but also discovered the essence that the bacteria keep survive along with human - being owing to highly adaptive ability 此项工作不仅揭示了波动生长有序结构的机制,而且深刻地认识到细菌以高度适应能力伴随人类生存。
Occurred in the neozoic , the strong himalayan movement made the first order and the second order structure units uplift to form maintains in the basin , which are unfav orable to preserve oil and gas 新生代发生的强烈的喜山运动,促使盆地内部各一、二级正向构造单元进一步冲断上隆、甚至生长为盆内山脉,对古油气藏保存不利。
A variety of methods have been explored to make photonic crystals materials from submicrometer balls of sio2 , polystyrene latex arranged into 3d ordered structures to porous , ceramic materials templated by this formed 3d ordered structures and oil emulsion 本文采用多种包覆方法结合,制备出这种对电磁场响应的复合微粒,并研究了各微粒的性能,及其在电磁场作用下的排列行为。
Connected rough structure with algebra structure , topology structure and order structure , many new prosperous mathematics branches will appear currently , there have been some articles on connecting rough structure with algebra structure 将粗糙结构与代数结构、拓扑结构、序结构不断整合,必将涌现出新的富有生机的数学分支。目前,粗糙结构与代数结构结合起来进行的研究已有文章出现。
Cells only the chromatin or chromosomes are heavily stained , the other components are bleached . after the chromosomes are stained by nama - ur , we have observed that the highest order structure of chromosomes is helical ; while the secondary structure is radically folding . the dna fibres with a diameter of 2530 nm have radically folded into chromatid fibres in a diameter of approximately 250 nm 染色体经dna特异染色后,观察到其最高层次结构是螺旋的,而次级结构存在着放射环结构,即由直径为2530 nm的dna纤丝放射状折叠排列成约250 nm左右的染色单体丝染色单体丝进一步螺旋形成中期染色体结构。
