构造的

Second, in the viewpoint of crypto analysis, the practical requirement for the cryptographic function is to construct the function that can resist all the known crypto analysis and attacks. In advanced, the main cryptographic properties are compared, and the relation among these cryptographic properties is analyzed, including the trade-off ones. Get the conclusion that the construction of cryptographic Boolean function is to find out the proper Boolean function in the whole vector space under the restriction of several cryptographic properties required for the security system.

然后本文从密码分析的角度，讨论了密码函数的实际需求，即构造能够抵抗已有密码分析与攻击的布尔函数；分析了布尔函数的主要的密码学性质，并比较了这些性质之间的相互关系，包括制约的关系；得出了构造布尔函数的实质的结论，即在向量空间中构造全体布尔函数，以所需的若干密码学性质作为限制条件，用有限域上的多项式、Walsh谱、Hadamard矩阵等数学工具找出适当的布尔函数用于加密体制的设计。

The internal structure of the Earth's poorly understood, or even Uu understanding, especially of the circle of the Earth's structure and the layer between the circle tilt differential problem is not the concept.

实验结果表明，该构造方法可以构造出非常复杂的曲面。

That means to calculate the Hessian matrix of optical flow equation, and the weight of Lucas-Kanade＇s method is defined as the reciprocal of the conditioning number of its Hessian matrix.

然后借用灰度直方图的概念构造方向直方图，提取光流特征，方向直方图由量化光流场来得到，再利用方向直方图构造出一个模板库及其索引序列库。

To promote solid earth sciences by development of plate tectonics is inevitable.

It is the structural stress that made the gold in the greenstone belts migrated and enri ched to form gold deposits.

构造应力使绿岩层中的金发生活化，迁移到构造有利部位富集成矿。

If T is a class type (clause 9) with a user-declared constructor (12.1), then the default constructor for T is called and the initialization is ill-formed if T has no accessible default constructor

也就是说如果T这个类具有用户自定义构造函数的话，那么"值初始化"（value-initialize）将会调用它；如果这个类是non-union类型且没有用户自定义的构造函数，则每一个非静态数据成员将会进行"值初始化"。

Classes that do not define the default constructor and/or the copy constructor impose serious limits on users of the class.

不定义复制构造函数和／或默认构造函数，会严重局限类的使用。
