查询词典 sieve classification

For example, Keyfitz made the classification of the bifurcations in one state variable, without symmetry up to codimension 7; Golubitsky and Schaeffer obtained the classification of the bifurcation problems in one state variable with Z_2 symmetry, in one parameter up to codimension 3; Golubitsky and Roberts studied the classification of degenerate Hopf bifurcation in two state variables with dihedron D_4 symmetry, in one parameter up to topological codimension 2; Melbourne obtained the classification of bifurcations in three state variables with octahedral symmetry, in one parameter, up to

需要指出的是以上研究均没有考虑分歧参数的对称性，Futer，Sitta和Stewart的工作虽然考虑了分歧参数的对称性，但仅限于分歧参数与状态变量具有相同的对称性，他们得到了状态变量与分歧参数均关于二面体群D_4对称，拓扑余维数不大于1的分歧问题的分类。高守平和李养成则讨论状态变量和分歧参数均具有对称性且对称性可以不同的分歧问题，并给出了状态(来源：A770707BC论文网www.abclunwen.com)变量关于二面体群D_4对称，分歧参数关于S~1对称，拓扑余维不超过1的分歧问题的分类。本文第一章讨论两个状态变量关于二面体群D_3对称，两个分歧参数关于O(2)对称的分歧问题，给出了该类分歧问题在非退化条件q(0)≠0下所有情形的分类与相应的识别条来源：AdadaBC论文网www.abclunwen.com

It is necessary to find a new method for garbage disposal. Compared to existent methods, landfill method of garbage block has its characters, which includes classification throwing, collection and predispose of garbage that make garbage disposal classification; use of reclaimable street collection that make garbage disposal resource; shatter,dehydration and press packing of garbage street collection that make garbage disposal decrease; disinfection and classification stack that attribute to classification administer and supervise of garbage field and make garbage disposal harmlessness; recycle, compost, burning and landfill that make garbage disposal synthesis; exploitation and use of garbage field that make garbage disposal environmental protection.

与已有的垃圾处理方法比较，垃圾块体填埋法有自己的特点，以社区为单元的垃圾源头分类投放、收集和预处理，能使垃圾实现分类化处理；通过垃圾中可回收废物的回收利用，能使垃圾最大限度资源化；通过垃圾分类粉碎、脱水、压缩成块体，使垃圾有效地减量化；经过消毒、分类堆砌有助于垃圾填埋场地的分类管理和安全监控，使垃圾处理基本无害化；回收、堆肥、焚烧、填埋，使垃圾处理综合化；填埋场的复垦与开发利用，使垃圾处理环保化。

The use of rock geomechanics classification method to increase the tiger to the right tunnel surrounding rock classification, the reference and evaluation criteria while rock classification method and the BQ were varied, but the same number of factors can be integrated indicators of scientific objective of rock classification for the tunnel to provide an important basis for the design and construction.

利用岩体地质力学分类方法对老虎岭隧道右幅进行围岩分类，其参考因素和评价标准虽然与BQ围岩分级方法不尽相同，但同样能够综合多因素综合指标，对围岩进行科学客观的分类，为隧道的设计施工提供重要依据。

The angle of every diffraction line of ZSM-5 molecular sieve determinedby X-raydiffraction, we obtained accurate lattice constant by using the least square method, and SiO_2/Al_2O_3 ratio of ZSM-5 molecular sieve according to empirical formula of lattice constant connectedwith SiO_2/Al_2O_3 ratio .

The results showed that the TEAOH possessed stronger framework-directing function during the synthesis process of SAPO-34 molecular sieve, and took up more electronegative framework positions while the morpholine mainly filled the micropore system of SAPO-34 molecular sieve.

结果表明，TEAOH在导向生成SAPO-34分子筛骨架过程中表现活跃，占据了较多的平衡骨架负电荷的位置，而吗啉主要起到填充分子筛孔道的作用。

The cortical cells had thin walls and mitochondrium, and nucleus wassurrounded by chloroplasts, and vesicles were next to cell plasmalemma. However, cellwalls of velamen, cortex and exodermis in the mycorrhiza of D. nobile had ring orpapillary thickenings in many cases. The hyphae were surrounded by moremitochondria and vesicles of plant, and the hyphae were digested and their structure waschanged at last. The cell wall of endodermis also had typical ring thickenings, and manysieve orifices in sieve tube elements of phloem were covered by callose, while therewere liaison cords in a few sieve orifices.
