对象

According to the specific features of AEC industry and info levels of AEC product, concepts of drawing cell, granularity of DC object and collaborative links are introduced to realize the CAD info integration, which maps the geometrical and topological constraints of product info into inner-correlation and outer-hyperlink of DCO.

文中针对工程设计的特点和工程产品的信息结构层次，通过"图元对象"概念的引入、图元对象粒度的建立和协同链接集成，在图元对象的内部关联和外部链接两个层次上建立了工程产品CAD信息集成模型。

Second, it clears the mark on the scavengers and the transitive closure of scavenger references. So if a scavenger object references a nonscavenger object then we clear the bits on the nonscavenger, and on everything that it refers to. I am using the word "closure" in a different sense than in my earlier post.

然后，gc清除scavenger的标记以及scavenger引用变量的闭包集合的成员的标记，所以如果一个scavenger对象指向另一个非scavenger对象，那么gc也清除那个对象的标记，并重复这一过程（这里"closure"的意思和我先前的一篇文章中的不同）。

One common strategy is to preallocate a block of raw memory to hold unconstructed objects. When new elements are created, they could be constructed in one of these preallocated objects. When elements are freed, we'd put them back in the block of preallocated objects rather than actually returning memory to the system.

一个通用策略是预先分配一场原始内存来保存未构造的对象，创建新元素的时候，可以在一个预先分配的对象中构造；释放元素的时候，将它们放回预先分配对象的块中，而不是将内存实际返还给系统。

The operator new function next checks whether there are any objects on the freelist. If not, it asks the allocator member to allocate chunk new, unconstructed objects. It then iterates through the newly allocated objects, setting the next pointer.

operator new 函数接着检查自由列表中是否有对象，如果没有，它就请求 allocator 成员分配 chunk 个新的未构造对象，然后，它通过新分配的对象进行迭代，设置 next 指针。

So,we should use conceptions of target of the criminal behavior and undertaker of so...

我们应彻底抛弃犯罪对象的概念，以行为对象和社会关系的物质承担者，来分别承担犯罪对象原有的两种功能。

When a Hero object is created, it can be passed to any of these methods, which means it is being upcast to each interface in turn.

当创建一个 Hero 的对象的时候，就会调用这些方法，这意味着那些对象要被上传转化为接口类的对象。

Since all objects in the class pool are upcast to their common base class, the polymorphism of the method leads to that which object method will be executed can only be ascertained at runtime.

由于所有位于对象池中的对象都被上溯到它们的基类型，方法多态使得只有在运行时刻才能真正确定到底哪个对象的方法被执行。

They can be any arbitrary Python object, i.e., from standard objects to user-defined objects.

他们可以是任意Python对象，即，从标准对象到用户自定义对象。

Firstly, working on the data model of temporal-relation, a bitemporal data model on object-relation is proposed in this paper, which may be implemented in current object-relational databases.

首先在现有时态关系数据模型基础上，提出了一种基于对象关系双时态数据模型，而这种数据模型适合于在现有数据库平台上实现；其次，在该模型框架内，讨论了时态对象关系模式与时态关系模式相互间的联系与转换，这也是由时态关系扩充到对象关系的基本要求：再次，分析了时态模型中时态变量复杂语义和相应绑定算法，这是时态数据库能够有效运行的基本课题

As an extension to the "973" Program of National Planning key basic research project -----the study of China lake nutrient over-enrichment process and the mechanism of blue alga outbreak, this paper introduces our experiments as below:(1) Experiment on heavy metal absorption and disorption abilities of Ceratophyllum demersum , Hydrilla verticillata and Myriophyllum triphyllum, in order to campare their absorption capability .

本文在前人的研究基础上，依托国家&973&国家重点基础研究规划项目&湖泊富营养化过程与蓝藻水华暴发机理&，开展了下列工作： 1、选取狐尾藻、金鱼藻、黑藻三种大型沉水植物作为研究对象，通过对重金属离子铜离子的吸附及解吸实验，比较其三种沉水植物之间吸附能力的大小； 2、选取狐尾藻、黑藻为研究对象，研究了重金属离子铜离子对沉水植物的胁迫作用及铜离子在植物体内的富集情况； 3、选取黑藻为研究对象，研究了沉水植物在富营养条件下不同浓度的氨态氮和硝态氮对沉水植物的生理生长的影响。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
