簇

Cluster is a relative steady microcosmic or sub-microcosmic congeries which is composed of several or even thousands of atoms or molecules through chemical or physical combining force .

团簇是由几个乃至数千个原子或分子通过一定的化学或物理结合力组成的相对稳定的微观或亚微观聚集体。

The two Armijo-type line searches proposed in Chapter 4 are shown to guarantee the global convergence of the class of conjugate gradient methods.

在第四章提出的两种Armijo型线搜索下，针对不同的线搜索参数分别讨论了共轭梯度法簇的全局收敛性。

In Chapter 7, the author investigates a class of conjugate gradient methods, which can be regarded as some kind of convex combination of the Fletcher-Reeves method and the method proposed by Dai et al.

第七章着重讨论一簇共轭梯度法，它可被看作是FR法和DY法的凸组合。

In constant acceleration growth, a retard effect of response of eu-tectic interflake spacing on the growth rate has been observed.

在加速生长过程中，共晶相间距对生长速度的响应呈滞后效应，响应机制是共晶Si相成簇分枝和局域"终结"延伸。

A primary goal in the design of wireless sensor networks is lifetime maximization,constrained by the energy capacity of batteries.So a critical issue is to strategically deploy an appropriate number of aggregators so as to minimize the amount of energy consumed by transporting the data.

无线传感器网络设计的一个主要目标就是最大化网络生命期，因此需要研究如何部署适当数量的簇头节点达到最小化整个网络节点数据传输能量消耗。

We focus on a particular class of subsets in the above topological space which is named support-bounded constructible subset as an analogue of constructible subsets in module variety and is invariant under derived equivalence.

我们研究了复形拓扑空间的一类特殊的子集合，称为支撑有界可构集，它是普通模簇上可构集在导出范畴上的类比并且是导出不变的。

Furthermore, we define a convolution multiplication between characteristic functions of constructible subsets by using push-forward functor from the category of algebraic varieties over C to the category of spaces of constructible functions. We construct geometric model for "intrinsic symmetry" of the octahedral axiom in a triangulated category. Using it, we deduce the multiplication satisfies the Jacobi identity of Lie algebra and then realize infinite dimensional Lie algebras.

进一步，我们使用复代数簇范畴到可构函数空间范畴的pushforward函子，给出了可构集上特征函数的卷积乘法，并构造了三角范畴八面体公理的内蕴对称性的几何模型，最终证明了对于不可分解支撑有界可构集的特征函数，乘法满足李代数定义的Jacobi恒等式，从而给出了无限维李代数的实现。

The continuation method just has the merit to deal with this set of vehicle models with varying parameters.

延续算法处理的也不是单一的车辆模型，而正是这个集合——模型簇。

The reconstruction of shower core is one of the key works of cosmic ray experiment based on terrene.

簇射芯位重建是基于地面的宇宙线观测实验的关键工作之一。

The number of cascade particles changes according to the incident cosmic ray energy, observation height, etc.

到达地面的簇射粒子数目会随不同因素而改变，包括原初宇宙射线的能量、观测高度等。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
