描述

Converts the specified floating point number into a character representation and copies the conversion into this descriptor, replacing any existing data.

描述使用特定的基数把浮点数转化为字符表达，并把转化结果拷贝的描述符，替换现有数据。

A formal model is proposed to describe time character of constraint in this paper.

提出一套形式化地描述时间特性的模型，使之能够描述带时间特性的授权约束。

So it is necessary to research on the definition, classification, characteristics, calculation, and formal model of directional relationships.

因此得出结论：研究空间方向关系中的最基本问题，即空间方向关系的定义、性质、特点、分类、形式化描述机制、基本计算等，是研究工作的当务之急，研究新的空间方向关系形式化描述模型很有必要。

The method is based on the formal EBE model that specifies only the external behavior of a protocol.

外部行为描述模型只对协议的外部行为进行描述，强调变迁之间的数据依赖性。

The goal of the attempt is construct an abstractive and object oriented data format to describe various subjects and make these information possible to be stored in one database, and provide integrated information search service.

这一设想的基本目标是利用一种抽象的、面向对象的数据结构定义描述各种事物，使描述不同事物的数据信息以类似 MARC 的方式混合存储在一个数据库中，提供综合性信息检索服务。

The first rule addresses the connection between a software system and the external systems with which it is connected; the next four all address a common issue - how modules will communicate.

第一件规则描述了一个软件系统和外部系统之间的连结关系；余下的全部四件描述了一个普通的议题-模块之间如何沟通。

Rotation, store the data in the matrix as an axis/angle and do the conversions yourself or will need to convert it to a quaternion.A quaternion is composed of four components: a vector with x, y, z coordinates and a w rotation.

当用一个四元数乘以一个向量时，实际上就是让该向量围绕着这个四元数所描述的旋转轴，转动这个四元数所描述的角度而得到的向量。

Comparing with classical viscoelastic models, fractional derivative models describe not only the constitutive of viscoelastic material and the related mechanics properties accurately in wide range, but also need less model parameters.

分数导数模型与其他经典模型相比不但能够精确地描述粘弹性材料的本构关系及其力学特性，而且确定模型所需实验参数少、能够在较宽的频率范围内描述材料的力学行为。

The state-space representation and the transfer function representation of fractional order linear time-invariant systems are introduced.

介绍了分数阶线性定常系统的状态方程描述和传递函数描述。

In order to overcome the difficulty of making a through investigation of each fracture in natural systems, a new concept of quasi double-porosity-medium was put forword and a new mcdel was also developed based on the partition of dominant fractured networks and quasi porous matrixes according to the transmissive and storage mechanism of frae tured medium.

双重介质水流耦合离散模型的建立，改变了以往对双重介质的概化和假设，能如实的反映裂隙系统和孔隙岩块的组合关系，不仅能描述裂隙系统的导水作用和孔隙岩块的贮水作用，还能描述孔隙岩块的渗透特征。对两类空隙系统间的水交替特点有了新的认识，并对以往的结论提出异议。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
