查询词典 ordered chain complex

The transition matrix that is also called the environment of Markov chain is a key factor of Markov chain.

影响马氏链的一个关键问题就是转移矩阵，亦称之为马氏链的环境。

As applications, we prove the following results: If / has pointwise pseudo-orbit tracing property, for any k ∈ Z+, and fk is chain transitive, then for any k ∈ Z+, fk has open set transitive ; If f has pointwise pseudo-orbit tracing property, and for any n ∈ Z+,fn is chain transitive, then f has sensitive dependence on initial conditions; If f is open set mixing and has pointwise pseudo-orbit tracing property, then f has property P; Let f :→ be a homeomophism, then f is pointwise pseudo-orbit tracing property if and only if the shift map σf is pointwise pseudo-orbit tracing property.

作为应用，证明如下结论：若f具有逐点伪轨跟踪性质，且对任意k∈Z+，fk为链转换的，那么对任意k∈Z+，fk为开集转换；若f具有逐点伪轨跟踪性质，且对任意n∈Z+，fn为链转换的，则f具有初始敏感依赖性质；若f为开集混合的，且具有逐点伪轨跟踪性质，那么f具有性质P；设f：→是同胚映射，那么f具有逐点伪轨跟踪性质当且仅当移位映射σf具有逐点伪轨跟踪性质。

Firstly a fast direct computing 3kP algorithm in field was deduced,which only needed one inversion;the new double base number chain based on 1/2 and 3 could be integrated with high-speed direct computing 3kP and halving algorithm.Scalar multiplication based on the new chain only employed point addition,halving algorithm,triplication and direct...

在底层域推导出直接计算3kP的快速算法，该算法只需一次求逆；新设计的以1/2和3为基的双基数编码可结合高效的直接计算3kP和折半运算，基于该双基数编码的标量乘算法只涉及到点加运算、折半运算、三倍点和直接计算3kP，底层域运算复杂性得到降低，在NIST推荐的椭圆曲线上比Dimitrov算法效率提高70%以上，比Wong方法提高10%以上。

An effective supply-chain management is capable of avoiding the overstock or understock in various sections of the chain, through which reduces cost of inventory management.

有效的供应链管理，可以避免造成存货在不同环节出现的积压或短缺，降低存货管理成本。

The uniformization embeded Markov chain is used to study the sensitivity of a continuos-time Markov process. It is proved that sensitivity estimators provided by the embeded Markov chain have less variance.

提出了用一致化嵌入马氏链来研究连续时间马氏过程的灵敏度分析方法，证明了用嵌入马氏链不仅实现简单而且还可以减小灵敏度估计量的方差。

The unimolecular decomposition and dehydrogenation of ethanol initiate the branched chain reaction, and the 3 isomers of radical C2H5O determine the direction of the reaction chain branching.

乙醇氧化经裂解反应、脱氢反应最终形成支链反应，乙氧基C2H5O的三种同分异构体在链分支中决定了链分支的进行方向。

The results showed that:(1) With increasing of the length of the carbon chain, the reducing of degree of unsaturation and not introducing the branched-chain, the tribological performance enhances. But with increasing of the added volume, the tribological performance does not always enhance.

结果表明：(1)随着合成酯的碳链长度增加、不饱和度减小及支链的非引入，摩擦学性能增强；但添加量增大，摩擦学性能并非一直增强。
