当您首次为一个信息集合构造一个xml模型时，通常应将这个信息集合定义为一个元素集合并使用属性来改进这个元素结构。
When you first construct an XML model for an information set, it's often useful to define the information set as a collection of elements and refine the element structure with attributes.
SDO有一个很重要的特点就是使数据操作变得更容易了，因此一旦构造好一个数据图，很重要的一点就是需要使用SDOAPI来遍历树结构，并访问其中的元素。
An important part of SDO is to make data manipulation easier. So once a data Graph is constructed, it is important to be able to traverse the tree and to access its elements with the SDO API.
如何构造元素的结构是与构造组成关系数据库的列和表同样重要、复杂而且可能非常困难的设计问题。
How you construct models for elements is just as important, complex, and potentially difficult a design question as how you construct the columns and tables that comprise a relational database.
在构造“结果树”的过程中，来自于“源树”的元素可以被任意地过滤、重组，以及添加任何的结构。
In constructing the result tree, elements from the source tree can be filtered and reordered, and arbitrary structure can be added.
正如BassL等人所指出的，视图是由系统参与者编写和读取的体系结构元素或构造以及它们之间关系的内聚集合。
As Bass l, et al. point out, a view is a coherent set of architectural elements or constructs along with the relationships among them, as written by and read by system stakeholders.
对数据元素解释毫无帮助的属性(糟糕的层次结构构造或属性的误用)。
Attributes that have nothing to do with data element interpretation (poor hierarchy construction or misuse of attributes).
在用抽象对象作为惟一元素构造出稳定的系统组织结构和应用框架后，从抽象对象派生出实例对象以实现框架和实例对象的分离。
System issues and application frameworks were constructed with abstract objects, and the instance objects were derived from the abstract objects to separate the frameworks with the instance objects.
根据这些玻璃质微球粒的物理、表面结构构造及常量元素等特征，可认为是微玻璃陨石。
These spherulites are identified as glassy microtektites by their surficial texture, physical and optical properties, and common element contents.
在构造预条件因子时，采用从目标的“几何结构剖分”出发，而不是从“矩阵元素”出发确定“基权函数之间的作用量关系”，这样保证了构造预条件矩阵的计算复杂度仅为O（N）。
The preconditioner is generated from the target's "geometry structure " and not from the "matrix element", which assured the computational complexity for generating the preconditioner is only O(N) .
