By analyzing the incidence matrix of chain structure model and tree structure model , incidence matrix was obtained , then topology information of basic network structures could be reflected 通过对网络的链状和树状基本结构关联矩阵的分析，认为关联矩阵可以完全反映网络基本结构的拓扑信息。
Applying laser tweezers to cylindrical vesicles of lipid bilayers induces an instability , which propagates down the vesicle leaving behind it a peristaltic state , which appears under the microscope as pearls on a string 在光镊的作用下，柱状膜表现出令人惊讶的动力学行为，即珠链状结构的形成及其发展后期的水珠运动现象。
We make up a simple model based on the microscopic mechanism of the membrane to investigate this phenomenon . the model proves reasonable after we quantify the velocity of the pearls drift slowly towards the laser trap 对于此动力学行为，本文从膜的微观结构出发，建立了一个简单的模型，解释了珠链状膜的形成以及光镊熄灭后水珠的运动。
The research was ultimately possible thanks to the unique composition of the fruit flies ' polytene cells - - giant , multistranded chromosomes with hundreds of sets of the genome instead of the usual two sets in conventional cells 这项研究可能最终还要感谢果蝇与众不同的染色体组成? ?巨大、多链状染色体，和一般细胞两套染色体不同，果蝇染色体有数百套之多。
Combining the engineering characteristic and the theory of markov chain , this paper inferred the forecast model of fuzzy markov chain , which had the fuzzy division of conditions and characteristics of no following effects in the main 摘要针对工程问题的特点结合马尔科夫链理论，提出了具备状态模糊划分和具有“大体无后效性”特点的模糊马尔科夫链状的预测模型。
Result of this paper can be used in not only chain - shape structures , but also inverse vibration design of complex structures , physical parameter identification , model modification and other related science fields of involving eigenvalue problems 本文的结果不仅适用于链状结构，而且适用于各类复杂结构的逆振动设计、物理参数识别和模型修改，也可用于涉及特征值问题的其他相关科学领域。
Nanostructured fe - ni alloy have been particularly emphasized because of their high permeability , low coercive force and relatively high saturation magnetization . fe - ni alloy fiber were also used as wave - absorbing materials . fe - co , co - ni , fe - co - ni alloy were armphous soft magnetic materials 其中fe - ni合金是纤维状的非晶态的软磁材料， fe - co合金为球形， co - ni合金也是球形，相互联结成链状。
Before life as we know it could exist on earth , conditions had to favour the creation of self - replicating molecules that enabled information to be passed on between generations . the first were probably chain - like molecules of amino acids or rna 我们知道，要生物可以在地球存在，地球首先要具备有利条件，让能自我复制的分子产生，使生命资讯可代代相传，而最先产生的很可能是氨基酸或核糖核酸的链状分子。
In the dissertation , we use graphs to describe the change of low status of logistics by the influence of ec , analyze the fourth generation of the logistics circulation mode , and then conclude that the modern logistics has been changed from chain of the past to net of now 本文首先用图形描绘了物流中三流地位由于电子商务的作用而产生的演变。分析了第四代物流流通模式的演变，得出第四代物流流通模式由过去的链状变为网状的结论。
Environmental mineral fibre mainly points crude minerals like sepiolite and palygorskite species layer - chained magnesian silicate , which have excellent physical - chemical properties and are rare environmental mineral materials in the world nowadays because of the rigor of their form conditions . the single crystals of palygorskite are mostly acicular and fibrous , 30 - 80nm of crystal diameter , and are typical crude nano - rank materials 环境矿物纤维主要指以海泡石、坡缕石类层链状镁质硅酸盐为主的天然矿物，具有优良的物化性能，由于其形成条件苛刻，为世界性稀缺的环境矿物材料，其单晶多为针状、纤维状，晶体直径为30 - 80nm ，属典型的天然纳米级材料。
